Who would have thought our ‘Black Jack’ would be a street art star…

 But he is! Even if he looks a bit like his good mate Graham Hill, replete with moustache!

Brabham is depicted aboard his 1966 F1 World Championship winning chassis- the Repco ‘RB620 Series’ V8 powered Brabham BT19, click on the links for articles on this bolide at the end of the article.

The artist didn’t realise just how perfect the placement of this sizable work is. Its on a wall in Richmond only 1.5 Km or so from the Doonside Street, Richmond Repco factory where the first of the RB620 V8’s were built and burst into life prior to the shift of Repco Brabham Engines Pty Ltd to Maidstone, in Melbourne’s inner west, in early 1966.

I came upon the art by accident whilst on a walk, its funny the way sometimes these things happen in a serendipitous kinda way.

‘Dimmey’s was an iconic department store in Swan Street Richmond. Its been redeveloped in the last few years- thank the good lord above that the developer was forced to retain the buildings base structure and façade, with the usual, small dog-box apartments contained therein. The big mural is painted on the side of the Dimmeys building. Initially I thought the work was some sort of history of Richmond but its a timeline depiction of ‘Great Australians’ and Oz icons, of whom our Jack is definitely one.

Melburnians can check out the art and have some nice nosh closeby whilst you do so- see the work on the Green Street sidestreet wall, corner of Swan Street. It won’t last forever mind you, it ain’t guarded like the Mona Lisa, if you want a look do so soon before the ‘taggers’ attack it.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

It gives me the pip that in popular listings of ‘Great Australian Sportsmen’ Brabham never pops up in the top 10 or 20.

He is a member of the Sport Australia ‘Hall Of Fame’. To me, hopelessly biased as I am, Brabham’s triumphs in 1966/67, lets put to one side his Drivers Championship wins for Cooper in 1959 and 1960, make him the greatest of any Australian sportsman/athlete.

Don Bradman the cricketer is usually rated at #1, big deal, most of you globally will have never seen a game of cricket. You are lucky, it’s a dull, shit-boring invention of the Brits. Often a ‘Test Match’, the elite form of the game, goes for 5 days without a result. Cricket even makes modern Petite Prix racing look exciting!

Brabham, Ron Tauranac and Repco made the ‘bat and ball’ and then they went and belted the best in the world with it. No-one else comes close to Brabham as our #1- not Ken Rosewall, (tennis) Mark Ella, (rugby) Betty Cuthbert, (sprinter) Rod Laver, (tennis) Herb Elliott, (distance runner) Dawn Fraser (swimmer) or Bradman, none of ‘em match his achievements in my book…

Footnote…

In 1966/1967 Jack Brabham and Denny Hulme won the World Drivers Championship aboard Brabham BT19 and BT19/20/24 respectively. Brabham/Motor Racing Developments were the Champion Constructor in both years powered by Repco RB620 and RB740 Series 3 litre V8 engines.

I’ve deliberately not captioned the mural shots- I don’t know all the names of the dudes depicted myself, so I’ve left it to Aussies to have some fun picking those people and events you can and wonder who/what the ones are you can’t identify! It’s great, do take the time to go and have a look.

The Story of the Repco-Brabham V8 Racing Engine as conveyed in Repco Technical News Volume 12 No 2, November 1965…

This gem is from Michael Gasking’s Collection and is reproduced in all of its glory, this is the 1966 Tasman/F1 engine later more commonly referred to as ‘RB620’, its internal Repco Parts Co project code was ‘620’. It will be difficult to read on your ‘phone, a bit easier on a larger device!

We have covered this engine already in primotipo, click on the links at the end of the article for these stories. Just a couple of ‘editorial comments’ or observations.

repco-1

RB620 and F1…

No mention is made of the engines F1 application so late in the piece, the new 3 litre F1 began on 1 January 1966. Brabham and Repco were playing their cards, understandably, close to their chest. Remember the RB620 V8 first ran in a car at 3 litres not 2.5, at Goodwood before racing in the non-championship South African GP, at Kyalami on 1 January 1966.

Melbourne motoring journalist Chris de Fraga, well known and respected by generations of Victorian enthusiasts is credited with first reporting Repco’s F1 plans in the Melbourne ‘Age’ in early October 1965, a report denied by Repco at the time. This document dated November 1965 was presumably circulated in that month or the following one.

Jack’s Lovechild…

Brabham’s parentage of the project is ignored in this largely technical treatise of the engine, Jack’s involvement not ‘front and centre’ in this public document given the need for F1 confidentiality.

repco-5

‘The Men’…

The duo credited with the engine in the brochure are Chief Engineer of the Repco Parts Group, Frank Hallam and Project Engineer Phil Irving, the only guy missing, as stated above is Brabham. Its worth musing for a bit about the roles these three men played in the championship winning RB620.

In simple terms Jack was the engines conceptual designer- he pitched the Repco board a simple engine using the F85 Olds block as a base whose completed dimensions were to fit the existing BT19 chassis. Phil designed it, inclusive of its drawings. Jack provided both conceptual design and practical feedback to Phil on regular visits to Irving who was based near Brabhams early in 1964 as he progressed the engines design. All of the ‘RB620’ drawings were done by Phil and signed by him according to ex-Repco engineer and Repco Historian, Nigel Tait who has seen and reviewed them all in the process of archiving them with RMIT University, Melbourne, in recent years. Hallam was Repco Brabham Engines Pty. Ltd. General Manager and Chief Engineer. His role was primarily a management one although he had engineering oversight, his direct design and engineering input into RB620 something Hallam has sought to grab a greater share of down the decades.

After Irving’s death, Hallam in his book ‘Mr Repco Brabham’ comprehensively dumps all over Irving and seeks to take more credit than he is due for the ‘RB620’ engine inclusive of positioning Irving as its ‘draftsman’ – ‘draftsman casual’ in the employee list in his books Appendix. In fact all of the ‘Drawing Office Personnel’ listed are described as ‘draftsman’ despite several being degree qualified engineers. Hallam, on the other hand, formally qualified as a motor mechanic, lists himself as General Manager/Chief Engineer. The positioning he inaccurately seeks to convey is clear. In that context its interesting to see Phil’s title as ‘Project Engineer’ in this Repco publication of the day.

The very well known F1 engine designer and manufacturer John Judd joined the Repco Brabham Engines Maidstone design team at Jack Brabham’s behest in 1966. He pretty much unwittingly walked into a storm in terms of the final breakdown in the progressively declining working relationship between Hallam and Irving. Judds arrival at Maidstone was unannounced by Frank to Phil, the design leader at the time, thereby lighting the fuse for a final confrontation which was becoming increasingly inevitable.

Judd got the ‘rounds of the kitchen’ from Phil when he joined RBE according to both Phil’s autobiography and Frank’s book but Judd has this to say about Irving’s contribution to ‘RB620’ in a recent ‘Vintage Racecar’ magazine interview;

‘When Jack returned (to the UK) from the (1966) Tasman  series, he asked if I could go to Melbourne almost immediately, and work with Repco designing parts toward the next year’s engine. That lasted for about four months and I was back again for six months in 1967 working on the 1968 4-cam engine.’

‘The original 1966 engine had been designed almost 100% by Phil Irving of Velocette and HRD fame with input from Jack and Ron Tauranac, but Phil didn’t fit in well with the Repco corporate structure and fell out with his boss Frank Hallam. My insertion into an already fragile situation led to Phil leaving after I had been there two months or so, and to his replacement by Norm Wilson. Looking back at Jack’s 1966 World Championship winning engine, I believe it was largely the product of one man, Phil Irving, to an extent that is and will remain unique.’

Don’t get me wrong, Hallam played a vastly important role in marshalling Repco corporate resources to assemble the men and modern machines to build World Championship winning engines in 1966 and 1967. He was also a wonderful foil between the demanding requirements of the Repco Board and the daily dramas in Maidstone of building and servicing racing V8 engines so far from Brabham Racing Organisation’s Guildford base. But his contribution is more management than engineering detail of RB620 when objectively looked at in the context of all the published evidence and the views of those there at the time.

The antipathy between Irving and Hallam was and is well known, few Repco people want to go ‘on record’ about the topic, which is both understandable and frustrating at the same time. They, rightfully, recognise the contributions of both men. Irving’s book is respectful of Hallam, Hallam’s of Irving not so and was published well after Phil’s death- the shit-canning of Irving is grubby and un-Australian really. If you are going to ‘have a crack’ do so when the other dude can defend himself. Hallam’s book was contracted by him from Simon Pinder, the author. It is not objective as such (neither is Irving’s autobiography of course) but does add much to fill in the RBE story, the long interview with ’67 RB740 designer Norman Wilson is gold for example,  but the books quality varies from gold to ‘merde’ depending upon the chapter. One needs quite a lot of Repco knowledge to pick the chapters to treasure and those to treat with rather more circumspection.

Nigel Tait told me that Jack Brabham was very angry with a fair bit of the contents of the book- it would have been a good idea for the great man to have read its contents before writing the publications foreword! I will explore the relationship between Irving and Hallam, and Hallam’s claims, in detail, soon. In short, this Repco corporate piece puffs up Hallam’s racing background and downplays Irving’s, ‘twould be interesting to know who ‘signed off’ the content of this document before it’s publication.

Enjoy ‘The Story of The Repco-Brabham V8 Racing Engine’, its sensational. Wish I had it when Rodway Wolfe and I tackled the articles linked below 2 years ago!, having said that we have included a good bit of granular stuff not included in this official publication, so read together are not a bad crack at the ‘RB620’ subject…

Jack Brabham willingly takes his go-faster pill from the lovely Goodyear fräulein…

It’s just before the 1966 German Grand Prix, Jack won the race in his Brabham BT19 Repco on 7 August from John Surtees and Jochen Rindt aboard Cooper T81 Masers.

Jack was right in the middle of the mid-season purple patch which gave him the title; from 3 July to 7 August he won the French, British, Dutch and German GP’s on the trot.

Goodyear were a very important part of Brabham Repco’s win that year. Jack was in F1 with them from their start in F1, 1965, and was still winning races with them in 1971.

Brabham’s last race win was aboard a Goodyear RR12 shod Bowin P4X Formula Ford ‘Race of Champions’ victory at Calder, Australia…

image

Bob Jane was always a clever promoter, the champion racer/entrepreneur and Calder circuit owner decided upon a ‘Race of Champions’ amongst the Australian aces of the day to get a few more bums on seats at his 15 August 1971, cold and chilly winter meeting. Look at the crowd!

The just retired, for a while anyway, Jack Brabham was happy to accept the invitation to compete. It just so happened his Ford Dealership in Sydney sponsored Bob Beasley in a Bowin P4 in that years ‘TAA Driver to Europe Series’, the national Formula Ford championship.

The field included Kevin Bartlett, Alan Hamilton, Allan Moffat. Pictured here is Bib Stillwell in the car in which Larry Perkins won the 1971 Driver to Europe title, then Jack and Frank Matich in Elfin 600, Bowin P4X and Aztec FF respectively.

Whether or not Jack did a few laps in the Bowin at Warwick Farm in Sydney before the car was popped onto the trailer for Melbourne is unclear, ditto Bib, the owner of the Perkins Elfin 600! It was a fun race but their were plenty of guys keen to win, Jack prevailed in the short scrap, Goodyear shod of course…

Ps: ‘Drink it Freddy!’…

Was the catchy slogan or tagline of a popular sweet drink called ‘Quik’, the notion being that the additive made cows milk more drinkable at a time such milk was a good thing. I think it still is, but who knows? Anyway, the line was stuck in the back of my head, which is full of useless shite and popped out when i saw Jack and his Goodyear friend…

Pps: Love the neato Repco Brabham sticker on the cockpit screen of Jack’s car!

Check out the view Maxxy!

Niel Allen and Max Stewart having a contretemps at Skyline, Mount Panorama, Bathurst, Easter 1969…

The bucolic terrain of New South Wales Central Tablelands stretches into the distance, the view probably not what the two drivers were focussed upon at the time. The race was the ’69 Bathurst Gold Star round, the field of which was substantially reduced by this first lap prang. The incident happened when Max misjudged his braking behind John Harvey, locked a brake and boofed the fence in his Mildren Waggott 1.6. Niel was right up Max’ chuff in his ex-Piers Courage McLaren M4A Ford FVA 1.6 and couldn’t avoid him. Out of shot is Queenslander Glynn Scott’s Bowin P3 FVA who also joined in the fun!

Here (above) is a shot of Harve’s Bob Jane owned Brabham BT23E Repco, it was Jack’s works ’68 Tasman car, sold to Bob at the end of the series then raced by John in the following years. In fact it wasn’t a lucky car for Harvey, he had a big accident at the same Easter meeting in ’68 when an upright broke, rooting the car and John. He was in hospital for quite a while after the prang, his speed undiminished when he returned to racing Jane’s stable of racers, sports-racers and tourers.

These fellas are favourites; property developer Allen was later as quick as Australia’s F5000 ‘Gold Standard’ Frank Matich without nearly as many seat miles, Stewart a multiple ‘Gold Star’ (1971/4) and AGP winner (19734/5) and Harvey a winner in everything he raced; speedcars, single-seaters, big sportscars and touring cars, the Bathurst enduro included.

Start of the Bathurst ’69 Gold Star race: front row comprises Max’ yellow Mildren Waggott, Niel Allen McLaren M4A FVA and on the inside Leo Geoghegan’s Lotus 39 Repco. The blue car behind is Glynn Scott’s Bowin P3 FVA and Harvey’s red Brabham BT23E, the torque of which clearly gobbled up Stewart and Allen on the steep climb up the mountain for Max to nearly run into him heading down the mountain. The white car is Henk Woelders’ 3rd placed Elfin 600 Ford t/c. You can just see Jacks red Brabham on the outside beginning his charge. He had fuel feed problems in practice so was off grid 7 with times well below the cars potential (Neville McKay)

The race was won by Jack Brabham’s F3 based Brabham BT31 Repco on a rare Gold Star Australian appearance fitted into his European program. This little jigger was powered by a 2.5 litre ‘830 Series’ SOHC, 2 valve Repco V8. Easter Bathurst is an historically significant meeting in Repco terms; it was Jack’s last Repco race and win in Australia. Brabham’s last International Repco races were those contested by he and Peter Revson in the USAC Championship that year in Brabham BT25’s powered by Repco ‘760 Series’ 4.2 litre DOHC, 4 valve, methanol fuelled V8’s.

This article was inspired by Lindsay Ross uploading quite a few images of this meeting on his oldracephotos.com Instagram page, check it out, they pop up a post every day or so. It seemed an idea to put the images floating around of this meeting in one place. I’ve an Instagram page too, as well as Facebook, just key ‘primotipo’ into the respective search engines and follow the prompts. The FB page has quite a lot of shots I don’t use on primotipo so may be worth a look every few days.

Brian Page in BT23A with ‘740 Series’ Repco, DNF with broken exhaust on lap 15 in the ex-Brabham/Scuderia Veloce machine (oldracephotos.com)

The first lap accident ruined what could have been an interesting race, Jack cruised to an easy race win by 1.5 minutes from Harvey’s car and Henk Woelders F2 Elfin 600B Ford t/cam.

Historically interesting is that this meeting was on the weekend of 7 April 1969, high-wings were banned globally at Monaco on the GP weekend of 18 May 1969, so it’s interesting to see the ‘Australian State of the Art’ in terms of fitment of said aero devices immediately before they were banned. Brabham tried the ‘bi-wing’ below setup on his BT31 in practice but raced with only a rear wing fitted.

image

Of arcane interest, perhaps (from the master of the arcane and tangential) is that all of Jacks ‘works’ Repco engined Tasman cars competed in this race bar one…

Brian Page’s BT23A(1) is JB’s ’67 Tasman car, Harve’s BT23E(1) is the ’68 weapon and Jack raced BT31 the car, late arriving in Australia, which did the ’69 Sandown round only.

Missing is BT19(F1-1-65) the chassis in which Jack won the ’66 World F1 Drivers and Constructors titles, and in 2.5 litre ‘620 Series’ engined form, raced in the ’66 Tasman Series, putting valuable pre-GP season race miles on Repco’s ‘brand-spankers’ V8 at Sandown and Longford.

The only car not in Oz now is BT23E(1) which was, and still may be in the US.

Whilst on the arcane it occurs to me is what a versatile, influential and successful design Ron Tauaranac’s BT23 space-frame was in the Brabham Pantheon…

’twas Ron’s clean sheet design for the new for ’67 1.6 litre European F2; it’s variants won a million F2 races over the following years in the hands of aces like Rindt but also in the care of privateer ‘coming-men’. Mind you it didn’t ever win the title despite winning 6 of the ten championship rounds in 1967, ‘graded drivers’ like Rindt were ineligible for championship points. Matra and Lotus took the ‘works entry’ approach more seriously than Jack and Ron during these years, in any event, as a customer racing car the BT23’s won lotsa races, the 1968 Rindt driven BT23C the most successful car of the year.

image

Jochen Rindt typically all ‘cocked up’ on the way to a win in the 9 July 1967 ‘GP de Rouen-les-Essarts’, Brabham BT23 Ford FVA. 1.6 litre F2 formula one of great chassis, it not engine diversity, Ford’s Cosworth FVA won every title from 1967 to 1971. F2 was 2 litre from ‘72 (unattributed)

From an F1 perspective the ’67 World Championship winning BT24 Repco was a ‘beefed up’ BT23, to the extent that Ron initially raced his BT24’s with an FT200 Hewland, the Maidenhead gearbox gurus ‘F2 box’ but found that tranny overstressed with ‘740 Series’ Repco V8 torque tearing away at its gizzards, its CWP in particular. I won’t bang on about the BT24 now as I’m in the process of writing an article about the ’67 Brabham/Repco winning season and go into much BT24 detail. Suffice it to say that the F2 BT23 begat the F1 BT24, my favourite Brabham.

image

Denny Hulme jumping his BT24 Repco at the Nurburgring during his ’67 Championship winning season. He won the German GP by 40 seconds from Jack (unattributed)

From an Australian viewpoint the BT23 Repco Tasman cars were very important as they provided much needed cars on skinny local grids…

The Tasman Series 2.5 Formula grids were ‘chockers’ with cars and stars, the domestic championship contained quality but not quantity. Budgets for these relatively expensive cars were hard to find in the sixties and Australia’s march to Touring Car domination was already well underway so ‘taxis’ were starting to absorb sponsorship budgets previously devoted to real racing cars.

Funnily enough, even though there was a swag of Repco engined BT23’s running around it was Alec Mildren’s, one off, 2.5 litre Alfa Romeo Tipo 33 V8 engined BT23D(1) which took a Gold Star. Frank Gardner raced this car in the ’68 Tasman, it was then taken over by Kevin Bartlett, the Aussie ace took the ’68 Gold Star in it. Repco never won a Gold Star title, a topic to explore at some stage during the Repco series of articles I am gradually writing with Rodway Wolfe and more recently Nigel Tait’s help.

image

Simply sensational Dick Simpson shot of Kevin Bartlett in BT23D Alfa, Hell Corner Bathurst Easter 1968, KB was walking away with the race until a broken rear upright ended his run. Dominant in this car in ‘68/9 (Dick Simpson)

Delving deeper into this BT23 tangent, whilst a BT23 Repco never won a Gold Star, a BT23 Waggott nee Mildren did…

Denny Hulme raced a works F2 Brabham BT23(5) FVA in the ’68 Tasman Series comprehensively boofing the car in the New Zealand Grand Prix at Pukekohe on 6 January, the series opening round.

Denny’s chassis was Jochen Rindt’s Winkelmann Racing entry in ’67, he won 9 Euro F2 races in it including the Rouen event pictured above. Another car (BT23-2) was sent from England for Denny to race in the rest of the series. Feo Stanton and Ian Rorison of Rorstan Racing bought the wreck and sent it to Rennmax Engineering in Sydney for Bob Britton to repair.

Instead of doing so Bob made a jig from the bent frame and sent a new chassis, the Rorstan Mk1 back to the Kiwis. Seven cars were built on the BT23 jig; the Rorstan, Mildren, two Rennmax BN2 and three BN3’s. Of these the Mildren, so named by Alec Mildren, the Sydney Alfa Romeo dealer, team owner and former Gold Star champion was the most successful. The Britton jig was also put to good use over the coming years repairing cars like Harvey’s bent BT23E!

Max Stewart ‘harry flatters in top gear’ heading down Surfers Paradise main straight and about to guide his 2 litre Waggott powered Mildren missile under the fast right hander and Dunlop Bridge. 9th in the ‘Surfers 100’ Tasman round in 1970 against the F5000’s. Graham McRae’s McLaren M10A Chev won the race but Bartlett’s 2 litre Mildren Mono Waggott was 2nd on this power circuit (Dick Simpson)

So…the Mildren pictured resting against the Skyline Armco fencing at this articles outset is a BT23 design. Max Stewart was prodigiously fast in the Mildren Waggott, he was one of those guys who seemed to get quicker as he got older, in ’69 he was quick, by the mid-seventies he absolutely flew in his Lola F5000’s. He was one of the very small number of blokes in Oz who squeezed absolutely everything out of these, big, demanding, fast, spectacular, fabulous 500bhp V8’s.

Bartlett, Matich, Allen, John McCormack, Bruce Allison, Warwick Brown, John Walker and Stewart in my book were the F5000 aces with Matich, if I have to pick one, the first among equals. Mind you, on sheer speed Alf Costanzo who came relatively late to the F5000 party could have been ‘the one’. Its an interesting topic to debate, end of F5000 tangent!

One of the pit sights which always amused me, and admittedly small things amuse small minds was big Max, he wasn’t a ‘fat bastard’, but he was 6’2”, crammimg himself into one of his cars before setting off for the dummy grid. If there was a taller bloke than Max in F5000 globally I’d be intrigued to know his name. He must have given away at least 10Kg to the rest of the grid before he even plopped his arse into the tight aluminium monocoque confines of the F5000 Lolas in which he excelled.

image

Max was big of stature and heart; here he is after winning the Rothmans International Series ‘Sandown Cup’ on 20 February 1977, his last big win, Lola T400 Chev, sadly not too long before his untimely death at Calder, 19 March 1977 (Ian Smith)

By the time Merv Waggott was building 2 litre variants of his superb DOHC, 4 valve, Lucas injected, bespoke aluminium blocked engines they were outright winners in 2.5 litre Tasman Formula events in the hands on the Mildren Duo, Messrs Bartlett and Stewart. The first Gold Star for F5000 was in 1971; Max’ Mildren Waggott won the Gold Star with about 275bhp from his close mate Bartlett in a much less nimble and reliable 500bhp McLaren M10B Chev in a year of speed and consistency. I don’t care what anyone says, F5000’s driven to their limit were always a little brittle.

So, to join the dots, a BT23 design did win the Gold Star albeit called a Mildren. Stewart’s Mildren Waggott and Bartlett’s Mildren ‘Yellow Submarine’ Waggott are tangents too far for this article and a wonderful future topic, there is a sensational article to be written there with Kevin Bartlett’s first-hand assistance on both chassis’ and engine if I ask him nicely…

Merv Waggott changing plugs in his baby, Wigram 1970. Bartlett’s Mildren Mono ‘Yellow Submarine’ Waggott (Bill Pottinger/the Roaring Season)

Merv Waggott changing plugs in one of his superb jewels. An all alloy, DOHC, gear driven 4 valve Lucas injected circa 275bhp 2 litre engine. Its in the back Of Kevin Bartlett’s Mildren ‘Yellow Sub’ Waggott, shot is in the Wigram paddock, 1970 Tasman round on 17 January on 7 December. KB had a lousy meeting, not setting a practice time and DNF on lap 6 with engine dramas, Stewart was 3rd though in his car, Matich the winner in his McLaren M10A Chev.

The Waggott 2 litre engine was first built in late 1969 and initially developed circa 250bhp, its output later circa 268-275bhp with about 160 lbs/ft of torque. It raced to a win in KB’s hands in the ‘Sub upon debut in the ’69 ‘Hordern Trophy’ at WF, KB won again at the 1970 Warwick Farm Tasman round ahead of all the F5000’s and 2.5 Tasman Formula cars.  2 litre Waggotts won Australias’ Gold Star in 1970 for Leo Geoghegan (Lotus 59) and Stewart in ’71 as noted above.

An article about Merv and his creations is a wonderful feature for another time. Briefly for international readers Waggott’s Sydney shop built race winning engines from the 1950’s, checkout the article below on the WM Special/Cooper T20 Waggott Holden twin-cam 6 cylinder raced by Jack Myers and tested by Stirling Moss in the late ‘50’s as some background.

Winding the clock forward, as the ANF1 2.5 litre formula spluttered on in the late sixties a ‘battle to the death’ was fought for the new ANF1 category in Oz between opposing forces who supported either F5000 or 2 litre F2. The latter to commence in Europe from 1 January 1972, F5000 commenced in Europe in 1969 and was born in the US as Formula A earlier still.

Waggott engines were initially of 1600cc, then later 1860cc and used the ubiquitous Ford Cortina block, same as Cosworth’s 1’6 litre FVA wherein Keith Duckworth tested his design ideas in advance of finalising his DFV design. In 1600 form the Waggott would have been Euro F2 legal, it used a production block as the regs required. The 1.6 litre F2 started in ’67 and ended in 1971 when it grew to 2 litres. There were a few FVA’s racing in Australia, the 1.6 Waggott more than a match for them, no Waggott’s, sadly, ever raced in Euro F2.

Lance Ruting studio shot of one of the engines, Ford block by the look of it so 1600 or 1860 (autopics.com)

Waggott 2 litre engines used a bespoke aluminium block as the stock cast iron Ford block maxxed out at about 1860cc. Beyond that the pistons kissed! Mike Hailwood’s Surtees TS10 won the ’72 Euro F2 Championship running Brian Hart built Ford BDA’s of 1850cc, those competitors running greater capacity than that had unreliability. The final Euro 2 litre F2 regs required production blocks from 1972-75 until ’76 when ‘racing engines’ were allowed. So, in the earliest years of the class the Waggott was ineligible.

Merv’s engines could have raced in F2 from ’76 but he had long before told CAMS to ‘shove it’ after F5000 was chosen (probably rightly given the backing of Ford, Holden and Repco who were building V8’s/wanting to develop an F5000 variant of the Holden engine in Repco’s case) as Australias’ new ANF1 from the 1971 Gold Star competition.

Had the ingenious, beautifully built little engine been Euro F2 Championship legal in 1972 Sydney’s Waggott Engineering had the winning engine! The engines were tried, tested championship winning donks ready to pop into any car. 275bhp and a big fat torque curve, Kevin Bartlett quoted the usable rev range of 6800-8750rpm, would have done the trick in 1972, the BMW M12 changed the F2 game from ’73 of course.

A wonderful ‘mighta-been’ all the same. Merv could have ‘stolen the F2 march’ in 1972 in much the same way Repco did in F1 with its Olds F85 production block based ‘620 Series’ V8 in 1966…

As motoring enthusiasts we all have a favourite (or two) when it comes to the various pressed, beaten or moulded automotive art…

The Italians have had a long tradition of art worthy cars for many to aspire. So what happens when the Art World decides to pay homage to a predominately Australian automotive heritage? Well you get the National Gallery of Victoria’s ‘Shifting Gear – design, innovation and the Australian car’ exhibition.

The NGV’s ‘Ian Potter Centre’ in high profile Federation Square, opposite Melbourne’s famous Flinders St Train Station has gone all out to show a variety of Aussie ‘coachbuilders’ art from the roads and the race tracks, ‘a celebration of Australian Automobile design represented by 23 cars dating from the late nineteenth century to the present day’.

Despite there being a lot of red involved, not one has an Italian sounding car name and only one has bodywork with a close relationship to Maserati.

NGV Efijy

‘Efijy’ – Shifting Gear? Or Cape Canaveral we have lift off? Holden built ‘Efijy’ as a Motor Show concept 10 years ago – Corvette basis, 6 litre supercharged GM LS2 644bhp V8 & 4 speed auto with ’55 FJ Holden looks

Upon entering the precinct, Holden’s Efijy greets you. It’s long and oh so low stance ready for cruising along Carlton’s Lygon St.

Then an entry fee covers viewing the main exhibition halls with more than enough variety for all to come away with a favourite that wouldn’t look too out of place sitting in your garage or shed.

It was a tad rushed when primotipo visited, so give yourself at least an hour to pass through and enjoy.

Several of the cars have long standing Australian Motor Racing Heritage, so it’s interesting to see how the Art World perceives them. Certainly different to the bitumen they usually frequent! And indeed, substantially different to seeing them at the likes of Phillip Island or Sandown.

A Unique arrangement that allowed some smart, capable Aussies to take on the world, Brabham BT19 Repco. Brabham and Tauranac based in the UK collaborated with Repco in Melbourne to gain a head start on the new 3 litre F1 Grand Prix rule changes for 1966. Jack and this Brabham successfully taking on the ill prepared other teams within the F1 paddocks and grabbed both Drivers’ & Constructors’ Titles in 1966 and 1967. (Denny Hulme grabbed the Drivers Title in 1967).

Regular readers will know we have covered the history of these achievements in some detail in previous posts; this one about the ‘RB620 series’ 1966 Championship winning engine…https://primotipo.com/2014/08/07/rb620-v8-building-the-1966-world-championship-winning-engine-rodways-repco-recollections-episode-2/

And in the red corner we have Purvis Eureka, Paul England’s Ausca (mostly hidden), Elfin Streamliner Climax and Molina Monza Holden…

NGV Group red

Garrie Coopers’ Elfin concerns first production racing car was the Elfin Streamliner, like many other designers he took a long look at Chapmans’ Lotus 11 and was consistent with many elements of it in his own interpretation; multi-tubular spaceframe chassis, slinky, light aluminium body and a range of engine configurations to suit customer choice. The car on display is the ‘ducks guts’ with Coventry Climax FWA engine and front wishbone, as against split front axle setup.

Elfin built 23 of these cars from 1959 to 1963, Cooper setting the foundations for high standards of design and manufacture which were his hallmark and sustained commercial success.

When Ausca met Eureka; Nice juxtaposition of the 70’s Wedge with the curvaceous 50’s. Not many cars have been built with full canopy door openings. But with the Purvis Eureka and Holden Hurricane this exhibition has two.

Allan Purvis, an advertising executive, obtained the rights to the English developed ‘Nova’ building over 650 cars in Melbournes’ Dandenong between 1973 and 1989 considerably improving the design as he went along. The car was based on VW Beetle chassis and mechanicals although Purvis built some cars with the Ford ‘Kent’ 1600 engine, a very ‘tunable lump’ with bits from Cosworth, Holbay and the like.

Despite its Maserati A6GCS looks, the Paul England-built Ausca has links to Repco and Holden too. A gifted engineer, the Ausca remains fitting testament to Paul’s skills of 60 years ago. He passed away last year

ausca and purvis

Paul England and his friend Bill Hickey built the Ausca in their spare time at Repco Research in Sydney Road, Brunswick the clever, light car having a ladder frame chassis, a fibre glass body, the pair making the moulds. Holden front suspension was used, England narrowing the track by cutting 6 inches out of the middle of the cross-member and a Holden rear axle casing also shortened by 3 inches, suspended by quarter elliptic springs, radius rods doing locational duties.

Steering was by Peugeot rack and pinion, Repco subsidiary Patons provided the drum brakes the car powered by the very first ‘Repco Hi-Power’ cross-flow head for the ubiquitous Holden ‘Grey Motor,  the engine good for around 115bhp @5000 rpm using 2 1 3/4in SU carbs 1956. Gearbox was a Fiat 521 using straight cut gears, the car first raced late in 1955.

The Chamberlain 8 is about the wildest Australian Special of all and deserving of an article in its own right…

Chamberlains’ as a family had a rich engineering heritage, originally manufacturing ball bearings and later tractors so Bob Chamberlain and his friend Bob Price had access to the toolroom and factory facilities to build their outrageously innovative space frame chassis, independently sprung, front wheel drive car.

First completed in 1928, the car evolved over the decades. After a succession of unreliable motor cycle engines Bill Chamberlain decided to build an engine himself. The result was a 1004cc 2 stroke with 4 cylinders and 8 pistons, two crankshafts and a Rootes type blower. Its scream was its hallmark @ 7000rpm, at a sedate 5000rpm it developed 80bhp.

chamber 1

The Chamberlain competed in 3 AGP’s at Phillip Island in the 1930’s coming into its own post war when one of the Chamberlain’s cousins, Jim Hawker built his own spark plugs and improved its electrical system.

The car never left the families hands and was restored for the 1978 Phillip Island 50 Year AGP Anniversary, its now owned by John Hazelden after the brothers deaths some years back. He is the lucky custodian of a very important part of our history.

NGV GTRX

One off, Torana GTR-X concept was still a fair way away from Holden’s 1969/70 production vehicles. As with most concept cars the economics didn’t stack up to sign off for production. It would have been part of a niche market catered by the likes of Datsun’s 240Z and even the Bolwell Nagari shown below.

A stunning car with bullet proof, race proven ‘186’ CID, pushrod OHV, triple Stromberg carbed 160bhp 6 cylinder engine hitting the road through a 4 speed close ratio gearbox…it should have been built and exported.

Repco Brabham ‘RB 750 Series’ V8…

Repco were a very innovative company, this is the engine developed as an option for the 1968 season and whilst developing good power on the test bench the difficulties of fitting the engine into Ron Tauranacs’ spaceframe chassis Brabhams’ or any other car for that matter are immediately apparent given the ‘spiders web’ of exhausts to be accommodated.

Developments of Repco’s ’30 Series’ heads showed there was a power advantage with cross flow gas paths, the ‘radial layout’ ’50 Series’ heads were aimed at exploiting that.

DOHC were used per bank, each one driving inlet and exhaust valves alternately. The valves were side by side in each half of a pent roofed combustion chamber. This layout allowed very simple valve operation compared with the BMW Apfelbeck ‘radial’ heads of the time. Doug Nye..’ On the Repco test heads exhaust stubs appeared within the Vee as a bunch of 8 small bore pipes, while 4 more appeared below the heads outside the Vee on either side. 8 induction trumpets fought for space within the Vee, and 4 more appeared on each side’.

One test engine was built up and the results were ‘encouraging’ but it was a blind alley because of installation problems…So the ‘Type 50′ heads were shelved and the more conventional ’60 series’ DOHC 4 valve heads used in 1968.

When i was 13 i drooled endlessly over the Bolwell Nagari, it really was ‘as good as it got’ in Australia. Home grown in dowdy Mordialloc but with Italian looks; the Chapman inspired backbone chassis a lightweight platform for the fibre-glass body and core Ford componentry; ‘302’ Windsor 5 litre V8, 4 speed ‘box and rear axle, live axle but very well located.

The Coupe version was even sexier than the ‘Spider’, Campbell Bolwell and his brothers were masters of the kit and low volume art…very tricky in a small market like Oz at a time the legislators made life hard for small players.

Molina Monza Holden Special…

In many ways the MM is the most powerful and beautiful of Australias’ Holden engined specials.

Concepted by Lou Molina, much loved member of Melbournes’ ‘Spaghetti Mafia’ who brought fine Italian cuisine to Melbourne between the wars and Silvio Massola, the car was designed and built by Brian Burnett, who by 1955, had the Maybach bodies in his cv. The car had a ladder frame chassis, an aluminium body that was derivative of many influences but wonderfully distinctive with it.

Motive power was the Holden ‘Grey motor’ with Repco Highpower head but also fitted with a Marshall blower fed by a big SU 2 3/16th ins. carb, 199bhp @ 6000rpm the result. Drive was transmitted by a dual plate clutch to a Jag ‘box and then by a short drive shaft to a de Dion rear end utilising Ford components. Front suspension is of planar type using a transverse spring to locate steering knuckles at the top, with wishbones below. Telescopic shocks are used front and rear. Steering is by Citroen rack and pinion, brakes drum using HWM Jag components at the front.

MM made its competition debut at Rob Roy in Melbournes’ Christmas Hills on May 5 1957 and was very successful in Molinas hands against much more exotic cars before slowly passing into obscurity before being superbly restored not so many years ago by Gavin and Bryan Sala.

It is a truly fabulous device.

The Holden Hurricane design study is about as far removed to their Holden production cars could ever be…

It was of course the era of low slung, mid-engined sporties such as the Ford GT40, De Tomaso Mangusta, Lamborghini Miura and even Lotus Europa. So Holden decided to give it a crack. One way to get the new ‘253’ CID Holden V8 noticed

NGV Hurricane

The car made its Melbourne Motor Show debut in 1969 and has a box section steel frame clothed in fibre glass panels. Wishbones, coil springs and dampers were used at the front, rear suspension uses swing axles, trailing arms and coil springs. The 4.2 litre pushrod OHV V8 produced 260bhp @ 6000rpm, the car uses a 4 speed manual ‘box and disc brakes on all corners. Height is 39.2 inches.

‘Hey Charger!’ the Ad Tag Line said in 1972…

The triple 45 DCOE Weber-fed Chrysler Valiant Charger’s played second fiddle to GTs and XU1s for too many years. But not anymore, they have a strong following and their values have increased substantially.

265 CID, in line OHV 6 cylinder engine, ‘E39’ 3 speed and ‘E49’ 4 speed ‘boxes. Never really developed as racers as Fords GTHO’s or Holdens XU-1’s but mighty competitive all the same.

The second episode covered the design and building of the 1966 ‘RB620’ V8, the engine which would contest and win the World Constructors and Drivers Championships in 1966, this is a summary of that season…

Brabham BT19 cutaway

Cutaway drawing of Brabham BT19 # ‘F1-1-65’, JB’s 1966 Championship Winning mount. Produced in 1965 for the stillborn Coventry Climax Flat 16 cylinder 1.5 litre F1 engine and modified by Ron Tauranac to fit the ‘RB620’ engine, which was designed by Phil Irving with Brabham/Tauranacs direct input in terms of ancilliaries etc to fit this chassis. A conventional light, agile, driver friendly and ‘chuckable’ spaceframe chassis Brabham of the period. Front suspension independent by upper and lower wishbones and coil spring/ damper units. Rear by upper top link, inverted lower wishbone, twin radius rods and coil spring/ damper units. Adjustable sway bars front and rear. Hewland HD500, and later DG300 ‘box. Much raced and winning chassis…still in Australia in Repcos’ ownership (Motoring News)

The 1966 South African Grand Prix…whilst not that year a Championship round was the first race of the new 3 litre F1 on 1 January. In December 1965 the first 3 Litre RB620 ‘E3’ was assembled and with slightly larger inlet valves, ports and throttle bodies than the ‘2.5’ produced 280bhp @ 7500rpm. After six hours testing it was rebuilt, shipped to the UK and fitted to Jacks ‘BT19’, a chassis built during 1965 for the stillborn Coventry Climax 16 cylinder engine, the rear frame modified to suit ‘RB620’. Brabham started from pole and lead until the Lucas injection metering unit drive coupling failed. He achieved fastest lap but was the only 3 litre present.

Straight after the race the car was flown to Melbourne and fitted  with  Repco 2.5 engine ‘E2’ for the Sandown Tasman round on February 27, Repco’s backyard or home event…

Rear suspension as described in cutaway drawing above, twin coils, fuel metering unit, HD500 Hewland, battery and ‘expensive’ Tudor oil breather mounted either side of ‘box (Brabhams World Championship Year’ magazine)

During a preliminary race the car set a lap record but an oil flow relief valve failed, causing engine damage which precluded Jack starting the championship race. Upon dissasembly, it was found a sintered gear in the pressure pump had broken. The engine was then rebuilt for the final Tasman round at Longford Tasmania. In a close race, the engine overheating, the car ran short of fuel and was beaten by the two 2 litre BRM P261’s (bored out 1.5 litre F1 cars) of Stewart and Graham Hill, Jackie Stewart easily winning the 1966 Tasman Championship for the Bourne team.

In early January the engine operation was transferred from Repco’s experimental labs in Richmond to the Maidstone address and factory covered in episode 2 where the operations were ‘productionised’ to build engines for both BRO (Brabham Racing Organisation) and  customers in Australasia.

So far the engine had not covered itself in glory but invaluable testing was being carried out and problems solved.

Meanwhile back in Europe other teams were developing their cars for 1966…all teams faced the same challenge of a new formula, remember that Coventry Climax, the ‘Cosworth Engineering’ of the day were not building engines forcing the ‘English Garagistes’ as Enzo Ferrari disparagingly described the teams to find alternatives, as Jack had with Repco.

Ferrari were expected to do well, as they had done with the introduction of the 1.5 litre Formula in 1961, they had a new chassis and an engine ‘in stock’, essentially a 3 litre variant of their 3.3 litre P2 Sports Car engine, the ‘box derived from that car as well, the gorgeous bolide looked the goods but was heavy and not as powerful as was claimed or perhaps Repcos’ horses were stallions and the Italian’s geldings!

Ferrari 312 1966 cutaway

Hubris or too little focus on F1 in 1966…on paper the Ferrari 312 shoulda’ won in ’66…when Surtees left so did their title hopes, Ferraris’ decline in the season was matched by Brabhams’ lift…

Cooper also used a V12, a 3 litre, updated variant of the 2.5 litre engine Maserati developed at the end of the 250F program in 1957 when it was tested but unraced.

Cooper T81 Maserati engine 1966

Coopers’ 1966 T81 was an aluminium monocoque chassis carrying a development of Masers’ 10 year old ‘Tipo 10’ 60 degree V12. DOHC, 2 valves per cylinder, Lucas injected, and a claimed 360bhp @ 9500rpm. The cars were heavy, reasonably reliable. Surtees and Rindt extracted all from them (Bernard Cahier)

Dan Gurney had left Brabham and built a superb car designed by ex-Lotus designer Len Terry. The T1G Eagle was to use Coventry Climax 2.7 litre FPF power until Dans’ own Gurney-Weslake V12 was ready. Again, the car was heavy as it was designed for both Grand Prix and Indianapolis Racing where regulation compliance added weight.

Denny Hulme stepped up to fulltime F1 to support Jack in the other Brabham.

The dominant marque of the 1.5 litre formula , Lotus were caught without an engine and contracted with BRM for their complex ‘H16’ and were relying also on a 2 litre variant of the Coventry Climax FWMV 1.5 V8…simultaneously Keith Duckworth was designing and building the Ford funded Cosworth DFV, but its debut was not until the Dutch Grand Prix in 1967.

BRM, having failed to learn the lessons of complexity with their supercharged V16 1.5 litre engine of the early 50’s, and then reaping the benefits of simplicity with the P25/P48/P57, designed the P83 ‘H16’, essentially two of their 1.5 litre V8’s at 180 degrees, one atop the other with the crankshafts geared together. They, like Lotus were also using 2 litre variants of their very fast, compact, light and simple 1965 F1 cars, the P261 whilst developing their ‘H16′ contender.

Honda won the last race of the 1.5 litre formula in Mexico 1965 and were busy on a 3 litre V12 engined car, the RA273 appeared later in the season in Richie Ginthers’ hands.

Ginther Honda RA273 , Monza 1966

Richie Ginthers’ powerful but corpulent, make that mobidly obese Honda RA 273 at Monza, the heaviest but most powerful car of 1966…it appeared too late in the season to have an impact but was competitive in Richies’ hands, a winner in ’67 at Monza…(unattributed)

Bruce Mclaren produced his first GP cars, the Mclaren M2A and M2B, technically advanced monocoque chassis of Mallite construction, a composite of balsa wood bonded between sheets of  aluminium on each side. His engine solution was the Ford ‘Indy’ quad cam 4.2 litre V8, reduced to 3 litres, despite a lot of work by Traco, the engine whose dimensions were vast and heavy, developed way too little power, the engine and gearbox weighing not much less than BT19 in total…He also tried an Italian Serenissima engine without success.

So, at the seasons outset Brabham were in a pretty good position with a thoroughly tested engine, but light on power and on weight in relation to Ferrari who looked handily placed…

Brabham contested two further non-championship races…with the original engine in Syracuse where fuel injection problems caused a DNF and at Silverstone on May 14 where the car and engine achieved their first wins, Brabham also setting the fastest lap of the ‘International Trophy’.

Monaco was the first round of the 1966 F1 Championship on May 22…Clark qualified his small, light Lotus 33 on pole with John Surtees in the new Ferrari alongside. Jack was feeling unwell, and the cars were late arriving after a British seamens strike, Jack recorded a DNF, his Hewland HD 500 gearbox jammed in gear. Mike Hewland was working on a stronger gearbox for the new formula, Jack used the new ‘DG300′ transaxle for the first time at Spa. Clarks’ ‘bullet-proof’ Lotus 33 broke an upright, then Surtees’ Ferrari should have won but the ‘slippery diff’ failed leaving victory to Jackie Stewarts’ 2 litre BRM P261.

Off to Spa, and whilst Brabham was only fourth on the grid…he was quietly confident but a deluge on the first lap caused eight cars to spin, the biggest accident of Jackie Stewarts’ career causing a change in his personal attitude to driver, car and circuit safety which was to positively reverberate around the sport for a decade.

Surtees won the race from Jochen Rindt in a display of enormous bravery in a car not the calibre of the Ferrari or Brabham, Jack finished fourth behind the other Ferrari of Lorenzo Bandini. Denny Hulme still driving a Climax engined Brabham.

At this stage of the season, the ‘bookies pick’, Ferrari were looking pretty handy.

BRM P83, Stewart, Oulton Park 1966

Another major new car of 1966 was the BRM P83 ‘H16’…love this shot of Jackie Stewart trying to grab hold of the big, unruly beast at the Oulton Park ‘Spring Cup’ 1966. The car got better as 1966 became 1967 but then so too did the opposition, the message of Brabham simplicity well and truly rammed home when the Lotus 49 Ford appeared at Zandvoort in May 1967…free-loading spectators having a wonderful view! (Brian Watson)

Goodyear…

Dunlops’ dominance of Grand Prix racing started with Engleberts’ final victory when Peter Collins won the British Grand Prix for Ferrari in 1958.

Essentially Dunlops’ racing tyres were developed for relatively heavy sports prototypes, as a consequence the light 1.5 litre cars could compete on the same set of tyres for up to four GP’s Jimmy Clark doing so in his Lotus 25 in 1963!

Goodyear provided tyres for Lance Reventlows’ Scarab team in 1959, returned to Indianapolis in 1963, to Europe in Frank Gardners’ Willment entered Lotus 27 F2 at Pau in 1964 and finally Grand Prix racing with Honda in 1964.

In a typically shrewd deal, Brabham signed with Goodyear in 1965, it’s first tyres for the Tasman series in 1965 were completely unsuitable but within days a new compound had been developed for Australian conditions, this was indicative of the American giants commitment to win.

By 1966 Goodyear was ready for its attack on the world championship, we should not forget the contribution Goodyears’ tyre technology made to Brabhams’ wins in both the F1 World Championship and Brabham Honda victory in the F2 Championship that same year.

Equally Goodyear acknowledged Brabhams’ supreme testing ability in developing its product which was readily sought by other competitors at a time when Dunlop and Firestone were also competing…a ‘tyre war’ unlike the one supplier nonsense which prevails in most categories these days.

The French Grand Prix was the turning point of the season…Brabham arrived with three cars, Hulmes’ Climax engined car as a spare and finally an ‘RB620’ engined car for the Kiwi. Perhaps even more critically for Brabham, John Surtees had left Ferrari in one of the ‘Palace Upheavals’ which occurred at Maranello from time to time, fundamentally around Surtees view on the lack of F1 emphasis, the team still very much focussed on LeMans and the World Sports Car Championship, where the marques decade long dominance was being challenged by Ford.

Surtees was also, he felt, being ‘back-doored’ as team-leader by team-manager Eugenio Dragoni in choices involving his protege, Lorenzo Bandini. The net effect, whatever the exact circumstances was that Surtees, the only Ferrari driver capable of winning the ’66 title moved to Cooper, Bandini and Mike Parkes whilst good drivers were not an ace of 1964 World Champ, Surtees calibre…

Rheims was the ultimate power circuit so it was not a surprise when four V12’s were in front of Brabham on the grid, the Surtees and Rindt Coopers and the two Ferraris. Surtees Cooper failed, and Jack hung on, but was losing ground to Bandini, until his throttle cable broke with Brabham leading and then winning the race.

It was Jacks’ first Championship GP win since 1960, and the first win for a driver in a car of his own manufacture, a feat only, so far matched by Dan Gurney at Spa in 1967.

It was, and is a stunning achievement, but their was still a championship to be won.

Brabham’s BT19 leads out of Druids at Brands Hatch, ’66 British GP. Gurney Eagle T1G Climax, Hulme’s Brabham BT20 Repco, Clark’s Lotus 33 Climax and the two Cooper T81 Masers of Surtees inside and Rindt, then Stewart’s BRM P261 and McLaren’s white McLaren M2B Serenissima and the rest (unattributed)

At Brands Hatch Ferrari did not appear…victims of an industrial dispute in Italy. Cooper were still sorting their Maser V12, the H16 BRM’s did not race nor did the Lotus 43, designed for the BRM engine. BRM and Lotus still relying on 2 litre cars. Brabham and Hulme were on pole and second on the grid, finishing in that order, a lap ahead of Hill and Clark.

Jack was tough but had a sense of humor…he had just turned 40 a month or so before, there was a lot in the press about his age so JB donned a beard, and with a jack-handle as walking stick approached BT19…much to the amusement of the Dutch crowd and press (Eric Koch)

Brabham and Hulme again qualified one-two but Jim Clark drove a stunning race in his 2 litre Lotus leading Jack for many laps, the crafty Brabham, just turned forty playing a waiting game and picking up the win after Clarks’ Climax broke its dynamic balancer, the Scot pitting for water and still being in second place when he returned, such was his pace. Clark fell back to third, Hill finishing second, the Ferraris’ and Coopers’ off the pace.

Bernard Cahiers’ famous shot of Brabham ‘playing with his Goodyears’ in the Dutch sand-dunes is still reproduced by Repco today and used as a ‘promo’ handout whenever this famous car, Jacks’ mount for the whole of his ’66 Championship campaign, still owned by Repco, is displayed in Australia

German GP grid 1966

German GP grid, Nurburgring 1966. I like this shot as it says a lot about the size of 1966 F1 cars and the relative performance of the ‘bored-out 1.5 litre cars vs. the new 3 litres at this stage of the formula. The only 3 litre on the front row, is Ferrari recent departee John Surtees Cooper Maserati #7, Clark is on pole #1 Lotus 33 Climax, #6 Stewart BRM P261, # 11 Scarfiotti Ferrari Dino, all ‘bored 1.5’s. Row 2 is Jack in BT19, and #9 and #10 Bandini and Parkes in Ferrari 312’s, all ‘3 litres’. The physical difference in size between the big, heavy Ferraris, and the little, light BT19 ‘born and built’ as a 1965 1.5 litre car for the stillborn Coventry Climax Flat 16 engine, is marked (unattributed)

The Nurburgring is the ultimate test of man and machine…Brabham qualified poorly in fifth after setup and gearbox dramas. Clark, Surtees, Stewart and Bandini were all ahead of Jack with only Surtees, of those drivers in a 3 litre car!

The race started in wet conditions, Jack slipped into second place after a great start by the end of lap one and past Surtees by the time the pack passed the pits, Surtees suffered clutch failure widening the gap between he and Brabham, Rindt in the other Cooper finishing third. Hulme was as high as fifth but lack of ignition ended his race.

Hill and Surtees were still slim championship chances as the circus moved on to Monza.

Ferrari traditionally perform well at home…and so it was, Ludovico Scarfiotti winning the race on September4.

Another power circuit, Brabham was outqualifed by five v12’s, the Ferraris of Parkes (pole) Scarfiotti and Bandini, the Cooper of Surtees and the Lotus 43 BRM of Clark in third.

The Ferraris lead from the start from Surtees, but Brabham sensing a slow pace took the lead only losing it when an inspection plate loosened at the front of the engine, burning oil, the lubricant not allowed to be topped up under FIA rules. Hulme moved into second as Jack retired. The lead changed many times but Surtees retirement handed the titles to Brabham, Scarfiotti winning the race from Parkes and Hulme.

The cars were scrutineered and weighed at Monza, the weights of the cars published by ‘Road and Track’ magazine. BT19 was ‘Twiggy’ at 1219Lb, the Cooper T81 1353Lb, BRM 1529Lb, similarly powered Lotus 43 1540Lb and Honda RA273 1635Lb. Lets say the Repcos’ horses were real at 310bhp, Ferrari and Coopers (Maserati) optimistic at 360 and BRMs’ and Hondas’ 400’ish also a tad optimistic…as to power to weight you do the calculations!

Jim Clarks’ Lotus 43 BRM achieved the ‘H16’s only victory at Watkins Glen…the Scot using BRM’s spare engine after his own ‘popped’ at the end of US Grand Prix practice. Jacks engine broke a cam follower in the race, Denny also retiring with low oil pressure.

The final round of the 1966 was in Mexico City on October 23…the race won by John Surtees from pole, in a year when he had been very competitive, and perhaps unlucky. Having said that, had he stayed at Ferrari perhaps he would have won the title, the Ferrari competitive in the right hands. Brabham was fourth on the grid, best of the non-V12’s with Richie Ginther again practicing well in the new, big, incredibly heavy V12 Honda RA273. Surtees’ development skills would be applied to this car in 1967.

Surtees finished ahead of Brabham and Hulme, despite strong pressure from both, whilst Clark was on the front row with the Lotus 43, the similarly engined BRM’s mid-grid, it was to be a long winter for the teams the postion of many not that much changed from the seasons commencement…

John Surtees, Jack and Jochen Rindt, Coopers T81 Maserati X2 and BT19. Mexican GP 1966. Ferrari missed Surtees intense competitiveness when he left them, the Cooper perhaps batting above its (very considerable!) weight as a consequence, Rindt no slouch mind you. The Coopers’ competitive despite the tough altitude and heat of Mexico City. (unattributed)

Malcolm Prestons’ book ‘Maybach to Holden’ records that 3 litre engines ‘E5, E6, E7 and E8’…were used by BRO in 1966, in addition to E3, all having at least one replacement block.

Some engines were returned to Melbourne for re-building and at least three were sold in cars by Brabham to South Africa and Switzerland, whether Repco actually consented to the sale of these engines, ‘on loan’ to BRO is a moot point!, but parts sales were certainly generated as a consequence.

Detail development of the ‘RB620’ during the season resulted in the engines producing 310 bhp @ 7500rpm with loads of torque and over 260bhp from 6000-8000rpm.

Back In Australia…

The Tasman ‘620’ 2.5 litre engine was not made available to Australasian customers in 1966, they were in 1967, a Repco prepared Coventry Climax FPF won the ‘Gold Star’, the Australian Drivers Championship in 1966, Spencer Martin winning the title in Bob Janes’ Brabham BT11A.

4.4 litre ‘RB620′ engines were built for Sports Cars, notably Bob Janes’ Elfin 400, we will cover those in a separate chapter.

Development of the F1 engine continued further in early 1966 in Maidstone, whilst production and re-building of the ‘RB620’ for BRO continued, we will cover the design and testing of what became the 1967 ‘RB740′ Series engine in the next episode…

Meanwhile Brabhams’, Tauranacs’, Irvings’ and Repcos’ achievements were being rightly celebrated in Australia where ingenuity, practicality and brilliant execution and development of a simple chassis and engine had triumphed over the best of the established automotive, racing and engineering giants of Europe…
