Jack Brabham attacks the Longford Viaduct in 1964, Brabham BT7A Climax…

His differential failed on lap 21 of the ‘South Pacific Trophy’, victory went to the Scuderia Veloce Brabham BT4 Climax driven by Graham Hill from Bruce McLaren’s Cooper T70 Climax.

I’ve accumulated a heap of photos of Jack Brabham, many of which are ‘human interest’ type shots taken in the paddock or at other important events. I’ve packaged them up in chronological order with some comments around the shot or the event, I hope you enjoy the selection.

Speedcar: Parramatta Speedway, Sydney 26 February 1954…

This photo is late in Jack’s speedway career, I’m not sure which chassis he is aboard above, he travelled to the UK in 1955 remember. In 1948 and 1949 he won the Australian Speedcar Championship in his #28 JAP 880 Midget.

In ’54 he was also racing his highly developed road racing Cooper T23 Bristol, contesting amongst many other events the ’54 AGP at Southport and the NZ GP at Ardmore. It was his showing in NZ which was one of the factors which convinced him to try  his hand in Europe.

Brabham’s first road racing competition was with his dirt midget, fitted with four- wheel brakes he won the 1951 Australian Hillclimb Championship in it at Rob Roy, in Melbourne’s outer east at Christmas Hills!

Cooper T43 Climax FPF: ‘Rochester Trophy’ Brands Hatch, 5 August 1957…

Jack and Geoff Brabham in the Brands paddock prior to this F2 race, he won both heats from two other Cooper T43’s of George Wicken and Ronnie Moore.

Jack looks so young- but he is already 31 and a veteran of nine years of competition, much of it on the dirt speedways of eastern Australia. Geoffrey is five- his racing car debut was in an Elfin 620 Formula Ford in 1972 or 1973, his first full season was aboard a Bowin P6F Formula Ford in 1974. Click here for an article on Geoff;

https://primotipo.com/2015/03/31/geoff-and-jack-brabham-monza-1966/

That season Brabham also won F2 events at Brands in June, the London Trophy at Crystal Palace, the Prix de Paris at Monthlery and the International Gold Cup at Oulton Park. In Grands Prix he contested the Monaco, French, British and Pescara events driving 2 litre FPF powered T43’s, his best, sixth place at Monaco.

Bursting onto stage…

Quite literally, Jack motors into the Dorchester Hotel, London ballroom to be presented with a BRDC Gold Star in 1960. By then he had won two World Titles on the trot of course, in Cooper T51 and T53 Climax in 1959 and 1960 respectively.

Jack and Bruce, Sandown Park, 12 March 1962…

Two great buddies, Jack instrumental in Bruce going to Europe and in ploughing the same path Bruce took with his own cars, three years later.

Jack has just left Cooper’s and ran a private ex-works Cooper T55 Climax 2.7 FPF in the Australasian Internationals that summer. Bruce also ran a Cooper T53 Climax FPF 2.7, like Jack, his own equipe prepared and entered the car.

Jack won the ‘Sandown Park International’ on the Sunday with Bruce third behind John Surtees in another (Yeoman Credit) T53 FPF 2.7. It was the opening meeting of the Sandown circuit, built as it is within the confines of a horse-racing facility. Its still in use, long may it continue!

Which Cooper are they leaning on? Dunno.

There are quite a few shots and information on that meeting in this article I wrote about Chuck Daigh a while back. Click here for a peep;

Icy Pole…

There are quite a few shots of Jack cooling down and warding off dehydration with a medicinal treat! Here its aboard his Lotus 24 Climax during the 1962 Belgian GP weekend at Spa. He was sixth in the race won by Jim Clark’s Lotus 25.

He left Cooper at the end of ’61 and raced the Lotus until the new Brabham BT3 was ready- its first appearance was in the German GP in early August.

Sandown Park paddock 1964, Brabham BT7A Climax…

This is the business end of the ‘Intercontinental’ Brabham shot in this articles first photograph at Longford.

Bruce won the first ’64 Tasman Series in the ‘very first McLaren’ his self built Cooper T70 Climax but Jack had a pretty good tour winning three of the races with Graham Hill picking up another in the David McKay owned BT4 as did Denny Hulme in his Motor Racing Developments BT4.

2.5 litre Coventry Climax FPF engine and using a Hewland HD5 gearbox- this very successful model, the BT7A and its BT11A successor won many races in Australasia and South Africa.

‘Warwick Farm 100’ paddock 12-14 February 1965…

Long time BRO mechanic Roy Billington looks on as Jack makes final adjustments to the Repco built and maintained Coventry Climax 2.5 litre FPF engine.

Jack finished second in the 45 lap race behind Jim Clark’s Lotus 32B Climax- Jim won the race, and three others to take the 1965 Tasman for Team Lotus. It was the start of an unbelievable year for the talented Scot who also won the F1 World Championship and Indy 500 in Lotus 33 Climax and Lotus 38 Ford respectively.

Repco obtained the rights to build CC engines in the early sixties- they did a nice trade supplying the locals and Internationals CC 2.5 bits, for many years the engine de jour of the category.

The Charlie Dean/Stan Jones fifties Maybach racing programs run out of Repco Research in Sydney Road, Brunswick created the ‘Repco Racing Culture’ and a swag of gifted engineers, fitters and mechanics who went on to do great things within Repco- and outside it.

The short ‘Coventry Climax Phase’ under Frank Hallam’s leadership in Richmond was an important bridge to the ‘Repco Brabham Engines Phase’ at Repco in terms of men and Hallam’s assembly of the necessary equipment to build and maintain the engines. He bought tools, milling machines, lathes etc. Frank used his budgets wisely to both buy new clobber and refurbish older but far from inadequate machinery.

In essence, the Repco Board believed they had the capacity to build racing engines when Canny Jack pitched the RBE 2.5 litre, Oldmobile F85 based Tasman V8 engine to them in 1963/4.

So, lets not forget the role the maintenance and limited development of the oh-so-successful Coventry Climax 2.5 litre FPF played in Repco’s ultimate 1966-1979 success. Why 1979 you say? The final national championship won by an RBE V8 was Paul Gibson’s win in the 1979 Australian Tourist Trophy at Winton in a Rennmax Repco powered by a 5 litre ‘740 Series’ RBE V8.

Monaco 1966, Brabham BT19 Repco at rest…

Jack resting with a Coke whilst being offered some encouragement from a couple of supporters. He wasn’t well, feeling off-colour, in addition BT19 was late due to a waterside workers strike in the UK.

He had just taken the newish BT19 Repco ‘620 Series’ V8 combinations first win in the Silverstone ‘International Trophy’ a fortnight before so much was expected of the combination in the principality of dreams. In the event the car jammed in gear from a lowly starting position leaving Stewart to win in a BRM P261- a 1.5 litre F1 car with a 2 litre ‘Tasman’ V8 fitted.

Jack’s title winning run started at Reims in July. Click here for my feature on the ’66 season;

OBE from HM The Queen…

Betty, Jack and Geoff Brabham having collected Jack’s Order of the British Empire from the Queen at Buckingham Palace in 1967. He was further honoured with a Knighthood, ‘Knight Bachelor’ in 1979.

Jack looks pretty schmick in tails but I imagine he could not get the ‘Topper’ off his head quick enough!

Victorious French Grand Prix, Le Mans 1967…

Jack won the race from Denny with Jackie Stewart third in an old BRM P261. I wrote an article about this meeting, click here to read it;

https://primotipo.com/2016/02/03/le-mans-french-gp-1967-powerrrr/

It was the fifth event of the championship season and the first win for the reigning champion. Meanwhile Denny was racking up a more than handy pile of points- which would win him the title from Jack and Jim Clark’s new Lotus 49 Ford DFV.

Ain’t she sweet! Ron Tauranac’s ’67 Brabham BT24 was one of his nicest, most cohesive, balanced GeePee designs. It had just enough of everything to do the trick and no more.

Note the characteristic duct to take cooling air within the Vee to keep stuff cool down there, not least the Lucas fuel metering unit. Duct used in the warmer ’67 races.

Mixing With The Big Shots, Melbourne Reception 1967…

Jack with Sir Charles McGrath, long time CEO and later Chairman of Repco Ltd and longtime Premier of Victoria Sir Henry Bolte to honour the achievements of both Brabham and Repco in 1966.

Jack’s suit lapel contains Repco and Goodyear pins reflecting the enormous contribution made by those companies to that success. Jack was a Goodyear early adopter and reaped all the benefits, in no small measure due to his ongoing testing feedback about the product.

McGrath was a Brabham believer, without his ongoing support there would have been no engines. At the time Repco Ltd were an Australian Stock Exchange Top 100 listed company, ‘Dave’ McGrath oversaw the exponential growth of Repco both within Australia and overseas from the time he was appointed Managing Director in 1953. He strode the local corporate scene like a colossus as a Director of Repco and other companies. Click here for his biography;

Gelato @ Monza ’67: ‘Streamliner’ Brabham BT24 Repco…

Proof positive he likes his icecream!

However light Ron Tauranac’s BT24 chassis was, the Repco ’67 ‘RB740’ V8 was still only good for 330 or so neddies compared with the 400’ish of the quad-cam 32 valve, new Ford Cosworth DFV. This aero experiment was successful in making the car slip through the air better but Jack had difficulty placing the car accurately through the complex, compound curvature of the screen so the project was abandoned. A works BT23 F2 car was also tested in similar manner.

This was the famous race in which Jack lost out on a last lap, last corner, braking manoeuvre with John Surtees Honda RA301 V12- losing out to finish second with Denny again behind in third. The big, beefy ‘Hondola’ had heaps more power than the Aussie V8 but equally as much bulk- the ‘pork chops’ of the era were the Hondas and BRM P83 H16. The leading ‘lithe and nimbles’ were the BT24 and Lotus 49.

Biggles Brabham at Bankstown, Sydney…

Brabham was a leading light of the fifties and sixties racer/pilots wasn’t he? Chapman, Hill, Clark and Reventlow all spring to mind. But there were plenty of others.

Here Jack has just arrived from the UK to Bankstown, Sydney on 11 February 1968.

That year he did a truncated two race Tasman in a beautiful Brabham BT23E Repco ‘740 Series’ V8. It was another lightweight purpose built Tasman jigger built on Tauranac’s F2 BT23 jig that could have nicked the title had he raced at all of the rounds. Mind you Jack would have had to knock over the two Gold Leaf Team Lotus Lotus 49 Ford DFW’s of Clark and Hill to do so. Clark was on tip-top form winning the championship with four victories.

I wrote an article about the BT23E, click here for it;

The Lowest Mileage Works Brabham: BT31 Repco…

Jack testing his 1969 Tasman mount, his just assembled BT31, in the late afternoon at Calder the day before it’s race debut at Sandown for the final Tasman round. Chris Amon won the race and the series that year in his works Ferrari Dino 246T V6.

My mate, Repco’s Rodway Wolfe helped Jack assemble BT31 that February day. Years later he owned the car, read his definitive story of this two races in period only, works Brabham!

Tailpiece: Suss the atmospherics of this Sandown Tasman shot 1965…

(R Lambert)

Whenever I see this fence I think of the number of times I jumped over it as a youngster. Not right there mind you, that spot was way too public. Clark’s victorious Lotus 32B Climax FPF is at left- he won five of the seven Tasman rounds and Jack’s Sandown winning Brabham BT11A is being fettled by Roy Billington and the chief himself. The senior advisor, Gary Brabham is just short of 5 years old i think. Check out the ‘Sandown muffler’ on JB’s car.

And the crowd takes it all in.

The original Sandown paddock did get a bit squeezy but boy it was a wonderful place to look at cars, drivers and the racing from the pit counter. Them was the days my friends…

Endpiece: JB, Jack Brabham Ford, Bankstown, Sydney 11 March 1971…

Jack retired from F1 and racing, sort of, he actually won a Formula Ford Race Of Champions in a Bowin P4X in 1971, at the end of 1970. Then there was his touring car ‘Dame Nellie Melba’ return in Taxis in the mid-seventies.

He sold his interest’s in Brabham Racing Organisation and Motor Racing Developments to Ron Tauranac and returned to Australia, at that stage having essentially an aviation business, Jack Brabham Ford on the Hume Highway at Bankstown and a farm at Wagga Wagga, 450 Km from Sydney, where he hoped to keep his sons well way from motor racing!

I’m such a sad little unit I can identify that tyre as a G800 Goodyear, not a bad radial in 1971 when this shot was taken. Jack was a ‘Goodyear Man’, I suspect this is some sort of promotion for the tyre and or the Ford Falcon XY behind the great one. Jack Brabham Ford offered a range of ‘tricked up’ Fords.

John Surtees poses with his Ferrari 312, the Scuderia’s 3 litre V12 new season and new formula contender, March 1966…

‘Big John’ is probably feeling fairly confident at this point, Ferrari seemed to be as well prepared as they had been for the last formula change from 2.5 to 1.5 litres in 1961. They took the title convincingly of course, Phil Hill won it in the Carlo Chiti designed ‘Sharknose’ 156 V6.

Coventry Climax had withdrawn as an engine provider at the end of 1965, other than some transitional support of Team Lotus with a couple of 2 litre FWMV V8’s to tide them over. Generally, 1966 was a year of transition and therefore of opportunity for those who started the season with a fast, reliable package, the Ferrari seemed just that.

‘Down Under’ Jack Brabham installed the first Oldsmobile F85 blocked Repco Brabham ‘RB620’ V8 into a year old Brabham chassis, BT19, built for the stillborn Coventry Climax Flat-16 engine and contested the Non-Championship South African GP at Kyalami in it on 1 January.

Repco then popped a 2.5 Tasman Formula RB620 V8 into BT19 for a couple of Tasman rounds, at Sandown Park and Longford, each time learning a little more about the engine and making it reliable.

Ferrari’s own 3 litre V12 was a trusty old warhorse which had served them well. It was a reliable Le Mans winning unit and more powerful than the Repco V8 but the car was heavy. Brabham’s BT19 was a light spaceframe and his 300 horses were stallions not geldings.

surtees 3

The first GP of the new F1, the 1966 XV Gran Premio di Siracusa was on 1 April, Surtees won it in a 312 from teammate Bandini’s Ferrari Dino 246. The only other ‘new’ F1’s were the Cooper T81 Maserati’s of Jo Siffert and Guy Ligier both of which failed to finish. So too did Brabham’s BT19 with a Repco failure.

On 14 May the teams met at Silverstone for the XVIII BRDC International Trophy which Brabham won from Surtees and Bonnier’s Cooper T81 Maser.

Game on!

Off to Monaco for the first Championship round on 22 May, Jackie Stewart’s BRM P261 took the race from Hill’s P261 both cars with 2 litre versions of the old P56 V8 1.5 litre F1 engine, and Bandini’s Dino. Surtees and Brabham were out on laps 16 and 17 respectively with transmission dramas.

Bandini’s use of the Dino which as the teams #1 Surtees should have been allowed to race, in Johns assessment the better of the two cars for the unique demands of Monaco, was one of many dramas within the team which famously resulted in the headstrong Brit telling Ferrari to ‘shove it’ costing both a title which they may well have taken.

Surtees joined Cooper for the balance of ’66 and made the cars sing but Jack was away and running taking the title he and Repco deserved but which perhaps should have been Maranello’s not Melbourne’s…

Ferrari 312 Specifications…

312 engine

The heart of any Ferrari is its engine of course, and what a glorious thing the Tipo 218 unit was.

Cast in aluminium alloy with cast iron wet cylinder liners, the 60 degree V12 had dual chain driven overhead camshafts per bank operating 2 valves per cylinder. The compression ratio was 11.8:1, heads incorporated 2 plugs per cylinder which were fired, old school, by a battery of 4 coils. The engine was dry sumped, the cylinders fed by Lucas indirect fuel injection. Claimed output was circa 360bhp at 10,000rpm, the reality probably a little less than that.

312 rear

The engine wasn’t really the cars weakness, it was probably more so the Tipo 589 chassis’s overall weight. Ferrari really didn’t get the hang of building a modern monocoque in the British idiom until they contracted John Thompson to build them one circa 1973!

Before then their tubs were sheet aluminium panels in a double wall riveted to a tubular steel structure. It was effective but heavy. The Ferrari’s suspension, as you can see is period typical; inboard at the front with a top rocker and lower wishbone and outboard at the rear with a single top link, inverted lower wishbone with forward facing radius rods for location. Uprights were cast magnesium with coil spring/shock units. Girling provided the disc brakes, which were inboard at the rear.

The Tipo 589 5 speed transaxle was sportscar derived, beefy and heavier than the DG300 Hewland box which became ‘de rigour’ in the Pommy cars of the era.

312 engine side

Shot above shows the beautiful standard of Ferrari fabrication and finish. Note the chassis, Lucas injection, twin-plug heads, alternator driven by the cams and wonderful exhausts which are fine examples of the pipe-benders art.

Tailpiece: Why is that Simple Little Thing So Fast?…

Enzo Ferrari ponders the 1966 consistent speed of Jack’s BT19 Repco at Monza on September 3 1966, the ‘Wonder From Down-Under’ beating the might of the Europeans…

What is he thinking I wonder? ‘why is it so fast, its last years spaceframe chassis, engine from someone i’ve never heard of in Australia and the block is an American Oldsmobile…’

In fact the following day was a good one for the Scuderia, Ludovico Scarfiotti’s 312 V12 took the win from Mike Parkes similar car with Denny Hulme’s Brabham BT20 Repco third.

 

 

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.

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.

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.

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.

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.

image

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…
