One of my true racing loves is the 1970 F1 Ferrari 312B and its successors.

I’ve done it to death of course, this article tells its story in detail: https://primotipo.com/2016/02/26/life-is-all-about-timing-chris-amon-and-the-ferrari-312b/ But this series of shots of an engine change during practice in Clay Regazzoni’s 312B/001 during the 1970 German GP weekend at the Hockenheim Motordrom are too good to ignore. We’ll make this the first of a similar series of a largely pictorial nature.

Doug Nye characterises this Mauro Forghieri – and team – designed machine as one the best integrated F1 Ferraris. The photographs here convey clearly why this is so.

The four main-bearing twelve cylinder engine – a Flat-12 or 180-degree V12 – depending upon your engineering religion of choice – was a paragon of reliable power after the early challenges experienced largely by Chris Amon circa-September 1969 were overcome.

These shots show how low, wide and compact it was. All that weight sat low in the chassis with the wild monocoque carrying the engine ‘underslung’. At that early stage of its development, Ferrari quote an output of 450bhp @ 12000rpm, a capacity of 2991.01cc and bore/stroke of 78.5×51.5mm.

Devoid of tyres, Regga’s #312B/001 sits on its tummy.

Note the inboard rocker front suspension – Ferrari had used this set up continually since the 1963 156 Aero – and clever way in which the aero-element rollbar stay ‘triangulates’ the monocoque boom. Oh to have been there to watch the engine replacement!

Ferrari still used their ‘Aero semi-monocoque’ at this stage, in that the tubular steel chassis had aluminium panels riveted to it with the engine used as a semi-stressed member.

Five of these chassis were built: 312B/001 – #312B/004 albeit #312B/002 was re-tubbed after Jacky Ickx’ collision with Jack Oliver’s BRM P153 during the 1970 Spanish GP. All four cars exist, what lucky owners they are! See oldracingcars.com for chassis by chassis details: https://www.oldracingcars.com/ferrari/312b/

#312B/001 was Ickx’ usual chassis throughout that season: the Austrian, Canadian and Mexican GP winner. As the chassis number suggests, this machine was the first built. It was entered for Chris Amon in the 1969 Italian Grand Prix but failed to take to the track after engine failure in three test sessions at Modena in the lead up to Monza.

Jochen Rindt won the Hockenheim race that weekend during the mid-season run of victories – the Dutch, French, British and German GPs – that gave the fearless Austrian enough points to win the World Drivers Championship posthumously. With a little more luck it could have been Jacky Ickx, but karma, thankfully prevailed.

In Germany the top-three qualifiers were Ickx, Rindt and Regazzoni. While the Ferrari challenge was strong, newcomer Regga – who won the Italian GP in September – led laps 22 and 23 of the race and was then slowed and retired with gearbox trouble in the 50 laps race.

Rindt’s win from Ickx was a good one, Denis Jenkinson noted in MotorSport that “As was very evident in Zandvoort it was the Lotus 72 showing superiority over the other competitors, rather than the driver…he (Rindt) won by only 0.7 sec from Ickx but the win was convincing as he was able to pass the Ferrari whenever he wished…”

More often than not the floor is a key contributor to the structural rigidity of both spaceframe and monocoque chassis – glued and riveted as they often are – but apparently not so much with this Ferrari, the floor of which was seemingly located by removable bolts. There are rubber fuel-bags within the monocoque on each side, mandated by the FIA from 1970.

Is Borsari the mechanic? I know the face of the longtime Scuderia man, I’m just not so sure of the name. Look how Forghieri is shifting weight to the very rear of the car: the Varley battery and neatly faired oil radiators. Outboard rear suspension is period-typical: cast magnesium uprights, single top links, inverted lower wishbones and twin radius rods, plus coil-spring/Koni dampers.

Finito…

I love these nudie-rudie shots, so many of a car’s secrets are revealed by photographs like this.

Jim Culp caught one of the Ferrari 312Bs raced by Jacky Ickx and Clay Regazzoni at Hockenheim over the August 2, 1970 German Grand Prix weekend coming off its transporter.

Key elements of Mauro Forghieri’s design on display are the low, wide 3-litre, fuel injected flat-12 (180 degree V12 if you prefer) engine and far-back weight distribution; the two oil tanks and related dry sump pump drives, battery, and twin, beautifully ducted oil coolers/radiators.

Ickx started the race from pole, with Regga third but Jochen Rindt’s Lotus 72 Ford prevailed over Ickx by a little less than a second, after a great long dice, with Regazzoni out with engine failure.

In a year of great sadness (deaths of Bruce McLaren at Goodwood and Piers Courage at Zandvoort) it was Jochen Rindt’s last win, and the start of a great run home for Ferrari.

Sheer economy of the design shown in this Hockenheim refuelling shot of Regga’s car (R Schlegelmilch)

Ickx won at the Osterreichring a fortnight later, and Regazzoni at Monza after Rindt’s tragic practice accident. Ickx won again at Mosport and Mexico City but Emerson Fittipaldi’s first GP win for Lotus at Watkins Glen helped ensure Rindt won the drivers title, and Lotus the manufacturers championship. Karma prevailed in an unusual year in which race wins were spread among drivers; Jack Brabham, Jackie Stewart, Pedro Rodriguez, Regazzoni, Ickx, Fittipaldi and Rindt.

Ferrari had a torrid time throughout 1968-69. The Ford Cosworth DFV was dominant and used by many of the front-runners. Team-leader, Chris Amon was in winning positions at least four times over this period only to be continually let down – Ickx’ ’68 French GP win duly noted.

The Lotus 72 made everything with a front radiator – the rest of the grid – look old, but the 312B was a very effective cohesive marriage of bespoke engine and chassis. Fast and reliable too (G Piola)
Chris Amon testing at Modena in late 1969. This shot shows the chassis ‘pontoon’ to which the engine mounts behind the top radius rod. Wonderfully neat and structurally rigid is the way the high roll bar braces to the rear of the pontoon, and forms the wing mount, and fire extinguisher mount!

Forghieri placed a new, clean sheet of drafting paper on his drawing board in 1969, the first such F1 occasion since he led the design of gorgeous, but never fully developed 1964-65 1.5-litre 1512 flat-12.

He again chose a flat-12 given its potential power output, low centre of gravity and lesser weight than the V12 it replaced. He made the engine a stressed member of the chassis, as was the engine on the 1512 – following the lead provided by Vittorio Jano’s Lancia D50 design – but this time the engine attached both to the rear bulkhead behind the driver, and underneath a ‘boom or pontoon’ chassis extension rearwards behind the drivers shoulders. The 1512 bolted to the rear bulkhead.

The Tipo 015 flat-12 – designed by Forghieri, Franco Rocchi and Giancarlo Bussi – was a great engine which powered the Scuderia’s Grand Prix cars from 1970 to 1980 (two drivers titles for Niki Lauda, and one for Jody Scheckter), and won them a World Endurance Championship when fitted in suitably detuned form to 312PB chassis in 1972.

There were a few teething problems early on however. To minimise friction losses and release a few more horses, the engine had only four main bearings, two plain shell bearings in the middle, and ball-bearing races at each end of the crank. With minimal support, crankshaft breakages were so much of a problem that Chris Amon cried “Enough!” and left the team, not even completing the 1969 GP season.

Ickx at Watkins Glen, he started from pole but pitted with a broken fuel line. In a tiger of a drive he went from 12th to fourth, Fittipaldi took his maiden GP win aboard a Lotus 72 Ford. Doesn’t the 312B look long from this angle? You can see the rearward weight bias and relatively clean air in which the rear wing operates thanks to the low engine (MotorSport)

A tilting dyno bed at Maranello enabled cornering oil surge to be monitored, the crank torsional vibration problem was fixed by adding a Pirelli cushion-coupling between the crankshaft and the flywheel.

Before too long the gear driven, twin-cam, four valve, Lucas injected engine produced a reliable 460bhp @ 11,500rpm, which rose over time to about 510bhp @ 12,000rpm.

While Chris made the works March 701 Ford sing in 1970, his solo Silverstone International Trophy win was no compensation for the four wins Ferrari produced with a car he put his heart and soul into at Modena in early testing…

Tifosi Monza 1970, Things Go Better With…(R Schlegelmilch)

While the Italian Grand Prix that year (above) was a terrible weekend, Ferrari had a home win, the tifosi went berserk and Mr Ferrari attended practice as he traditionally did.

Ickx started from pole, Regga was Q3 and Giunti Q5. Regazzoni was the only one of the three to finish, in the right spot too. Ignazio was out with fuel system woes after completing 14 laps, and Jacky with clutch troubles after 25 laps.

Regga won from Jackie Stewart’s March 701 Ford and Jean-Pierre Beltoise’ Matra MS120. Points of GP trivia are that it was the last time a GP was won by a driver wearing an open face helmet, and the last time the first three finishers used different tyre brands; Firestone, Dunlop and Goodyear in first to third respectively.

Clay Regazzoni oblivious to the ‘Queen Mary’s existence as he races to victory from pole in his Ferrari 312T, US Grand Prix West in March 1976…

I’ve never been to the place but Chris Pook’s idea was a great piece of entrepreneurship.

His first 1975 event, a marvellous demonstration of what is great about F5000 was followed by a championship GeePee in ’76. The other thing that captured my imagination about the place was the Depailler in-car Tyrrell footage. If you weren’t a PD fan, I always was, you had to be so after seeing him flick the 500bhp beastie through the Long Beach boulevards as though it were a 100bhp Lola T342 Formula Ford. The ability that separates the greats from the rest of us. Check it out if you’ve not seen it, look again if you have!;

Regga, a GP driver with a personality, they seem to breed it out of ‘em these days, anodyne boring liddl’ fuggers they all seem to be. The Swiss Italian had a great weekend in California winning from teammate Niki Lauda’s 312T and Depailler’s Tyrrell 007 DFV, the sound of which (Tyrrell 008 anyway) screaming in protest you can see, hear and feel in the footage above.

British GP, Brands 1970

A winning racing cars performance is greater than the sum of its individual components, said items often of great engineering beauty…

The left front corner of the 1970 F1 Ferrari 312B is a good example of an exquisite bit of a very cohesive design which was quicker than the ‘sum total of its bits’.

I wrote an article about this car, a personal favourite a while back, click here to read it;

Life Is All About Timing? Chris Amon and the Ferrari 312B…

So, what have we got?

The upright is fabricated rather than cast, the neat bracket to pick-up the steering arm has a few pick-ups indicative of a bit of experimentation.

The brake caliper is Girling’s, the F1 grid that year split between Girling and Lockheed as suppliers. The disc itself is 10.5 inches in diameter and is cast iron, the use of composites still a decade or so away.

I’ve a feeling Bruce McLaren may have introduced braided steel ‘Aeroquip’ lines for fluids into F1 via his exposure to them in his US Can Am campaigns, his ’66 M2B F1 car certainly had them. Ford fitted them to their Indy Ford V8 engines provided to Lotus from 1963 but Chapman didn’t quickly adopt them for brake and clutch lines in his cars. By ’70 they were F1 passe as here on Forghieri’s Fazz.

Chris Amon is not a driver one readily associates with the very successful 1970 Ferrari 312B and even then only in a ‘lost opportunity’ kind of way…

As he drove from his digs in Maranello the 20km to the Modena circuit Ferrari used for testing each time in mid 1969 he did so with an increasingly heavy heart.

Chris had motor racings dream job, Ferrari’s ‘number one’ driver and the considerable resources of the famed Scuderia at his disposal. He tested and raced F2 and Tasman Dino’s, Sports Prototypes, big Can-Am Group 7 cars and of course GP cars. The company car was not to be sneezed at. Ferrari’s drivers were only marginally less popular than the Pope, he loved living in Italy, enjoyed the food, people, the vibe in Maranello and testing the cars, Mauro Forghieri rated him one of the teams greatest test drivers and of course his racing of them.

But in his terms, as one of the five best drivers in the world at the time, he was not achieving the grand prix winning success he deserved, so many times he had led races in 1968 and early in 1969 only to have the car fail beneath him. And now, a car he thought looked fabulous and was testing well had an engine which consistently ‘grenaded’ behind him at Modena in the most spectacular fashion.

What should he do? Stay with Ferrari in the belief the engineering problem would be solved or move to another team with a Ford Cosworth powered car was the decision which tortured him…

The partnership between Amon and Mauro Forghieri was a fruitful one based on great mutual respect, which is not to say they always agreed! Here with 312 at Zandvoort in 1967. How young does he look?! Ferrari team-leader at 24 by the end of 1967 (unattributed)

He joined Ferrari in 1967 as one of four drivers- Lorenzo Bandini, Mike Parkes, Ludovico Scarfiotti and himself. The ‘pudgy’, heavy 312 of 1966 evolved into the 1967 car, quite the sexiest looking of any GP car. After the end of the sports car season it became a very fast one fitted with a lightweight block and F2 derived gearbox- and from Monza with four-valve heads the car flew. Amon believed the 390bhp claimed for it and described the (’67 and ’68) chassis as ‘an absolute dream to drive’. Chris should have won at Watkins Glen in front of the two Lotus 49s but the engine blew 12 laps from the end. In Mexico Chris qualified well in second but pitted for fuel.

A road accident early in the 1967 season put him out for a while, his speed had been demonstrated in all types of car, his place in the team was cemented despite an awful season for Ferrari- the tragic death of Bandini at Monaco and the effective end of Mike Parkes’ career in a huge, high speed Belgian GP, Spa shunt.

For 1968 his teammate was Belgian ‘Wunderkind’ Jacky Ickx.

One of the ‘crosses Ferrari F1 drivers sometimes bore’ was Enzo Ferrari’s obsession with sports car racing, particularly Le Mans. Whilst the team had better resources than most, the impact of the sports car program on F1 was great or little depending upon the competitiveness of said GP cars at the time! In mid-season, the focus was on the Sports Cars, after that F1 was re-prioritised.

In 1968 Ferrari ‘spat the dummy’ at  CSI rule changes (ending unlimited cars and changing to 5 litre Sports Cars and 3 litre Prototypes) not building a car for the season with a consequent focus on F1 and development of a car which could have won both ’68 world titles.

The 48 valve V12 was developed to give circa 410bhp at a time the Ford Cosworth DFV gave much the same, albeit the Fazz lacked the mid-range punch of the DFV, Amon quipped that ‘there was nothing at home below 9800rpm’. The engine also had high water and oil temperatures with consequent power loss. The Ferraris went to the grid carrying 8-10 gallons more ‘juice’ than the Cosworth cars, a weight penalty of 55-70 pounds, despite all of that the 312/68 was a very competitive, if unreliable beast.

French GP, Rouen 1968. Q5 and 10th in the race won by teammate Ickx, the ‘rainmaster’ who started the damp race on full wets and drove away in the early laps when, again, a driver, Jo Schlesser, died in another fiery accident in the Honda RA302. These accidents accelerated changes to circuit and car safety, not that they were the last horrible fiery deaths in the period. Amazing Rainer Schlegelmilch shot of Rouen and the butt of Amons 312; look at the hay bales, tyre distortion and the presence of wings which grew thru ’68 (Schlegelmilch)

In 1968 the grid was ‘awash’ with Ford Cosworth DFV’s- Lotus, McLaren and Ken Tyrrell’s Matra’s were fitted with them. Colin Chapman waived his exclusivity agreement to the engines upon Ford’s Walter Hayes request that he do so ‘for the good of GP racing’ such was Hayes’ fear of Lotus dominance. Not that Ford’s position was diminished by more DFV powered cars on the grid than less!

For Ferrari, BRM, Weslake and Honda the impact of the Ford engine was great. The DFV was built on modern, tape controlled equipment bought for the purpose which meant the quality of the product was consistent, parts made would fit all engines. Prior to that some GP engines were to an extent hand fettled and bits needed to be modified to fit each engine, which was effectively bespoke. Cosworth’s quality control and the pressure on them to rebuild the engines in a timely consistent way for all took a while to get sorted, but the writing was well and truly on the wall, the Ford engine a considerable F1 weapon of course right into the eighties and beyond in F3000 guise.

None of this was lost on Amon of course, the competitiveness of his compatriot Bruce McLaren’s cars in 1968 was something he observed and discussed with both Bruce and Denny Hulme.

Italian GP, Monza 9 August 1968. Giulio Borsari makes some adjustments to Ickx’ 312. Forghieri devised this ‘movable aerodynamic device’ operated by oil pressure. The wing went to hi-angle mode in 1/2/3rd gears but feathered for low drag with the throttle open in 4/5th gears. It returned to download position in those gears when the brakes were applied. An override switch was fitted which Chris liked and Ickx had removed (Klemantaski)

But Chris was ‘on fire’ in 1968. Ferrari were on the front row nine times, eight to Amon and took four poles, three to Amon, but unreliability robbed them, and Chris of three probable wins. Ickx took the only race win at Reims during the tragic French GP in which Jo Schlesser died in the Honda RA302.

At Monza Chris led until an oil leak onto a rear tyre caused an almighty accident which destroyed the car. He dominated in Canada despite clutchless gear changes from lap 12 but of course the gearbox broke under the strain, the clutch should not have failed.

1969 started well, Chris tested his 246 Dino Tasman cars thoroughly at Modena before shipping the cars home to New Zealand.

He convincingly won the Tasman Cup in 300bhp, 24 valve cars he helped develop and a team he put together. He collaborated with David McKay’s Sydney based Scuderia Veloce who provided on ground back-up for the mix of speed and reliability needed for this championship of intensity- eight races in eight weeks.

He beat the factory Lotus 49s of Hill and new-signing and probable ‘fastest guy on the planet’ Jochen Rindt taking four wins including the NZ GP at Pukekohe and AGP at Lakeside. The series of depth also included Derek Bell (in the other Dino), Frank Gardner (Mildren Alfa T33 V8) and Piers Courage (Brabham BT24 Ford DFW).

Back at Maranello the finishing touches were being made to the 312P, Ferrari were back in endurance racing that year, and the latest evolution of the 312 GP car.

Strategically the future for Ferrari was bright despite the financial difficulties the team were in early in the year.

Discussions underway with Fiat were consummated in June, Enzo Ferrari had effective control of the racing department for his lifetime whilst Fiat took over the development of the road cars, and a considerable amount of cash changed hands.

The injection of working capital allowed Ferrari to build the 25 512S Sports Cars required for homologation into Group 5 for 1970 and to develop Ferrari’s first ‘clean sheet’ 3 litre F1 car, the flat-12 312B.

Ferrari authorised Forghieri to start this program early in the year well before the Fiat deal was done, the Fiorano test facility, opened in 1972 is another example of the sort of investment which would not have been possible without Fiat’s investment.

Monaco 1969 Amon beside Jackie Stewart’s Matra MS80 Ford which won the title that year . Q2 anf a failed diff. Note the lack of wings, banned overnight by the CSI. Hill won in a Lotus 49 Ford (Yves Debraine)

From Amon’s perspective then, he was potentially in the right place.

He was esconced in one of the sports greatest teams, he had won the Tasman, Ferrari was in the process of doing a deal with a partner with deep pockets, a new car was underway for 1970 but 1969 could be a challenge with an evolution of the ’68 cars and more Cosworth powered cars on GP grids! It was critical to Chris the 312B tested well.

Whilst Mauro Forghieri worked on the design of the 312B Ing Stefano Jacoponi was responsible to do what he could with the obsolescent V12. The chassis was much the same although the cars appearance was different with a flatter nose and evolution of wings, partially at the whim of the (CSI) rulemakers who banned, rightly, high-wings during the Monaco GP weekend.

The V12 was changed with heads which reversed the porting, returning the exhausts to outside the Vee lowering the cars centre of gravity and reducing turbulence around the rear wing. Inlets were in the Vee, more radical cams were developed and disastrous efforts made to reduce frictional losses and release power by reducing main bearing area…

Amon Q5 and DNF lap 45 with gearbox failure. Stewart’s Matra won after a titanic battle with Rindt’s Lotus. 3 Ferrari’s were entered #32 the spare (unattributed)

Early in the season Ferrari entered only one car for Amon. He was second on the Spanish GP grid and inherited the lead after the two Lotus 49’s crashed with wing failure, with a lead of over 30 seconds the engine seized. At Monaco he was second when the diff failed and at Silverstone, joined by Pedro Rodriguez both retired with ‘box and engine failures.

To add to these frustrations and be in no doubt elite sport is as much mental as physical, his erstwhile teammate Ickx- Amon had been demonstrably the quicker of the two in 1968 was winning races in Brabham’s year old spaceframe chassis BT26. That car was now as consistently fast and reliable with a DFV in 1969 as it was consistently fast and unreliable with a Repco ‘RB860 Series’ V8 in 1968. Amon’s disappointment with his situation was immense, he was a race-winner in a reliable Ferrari or another car.

Such were their problems Ferrari withdrew from the German GP on 3 August, Ickx won there, to prepare the new 312B for Monza, it simply was not worth racing the fast but unreliable 312/69.

Amon had great hopes for Mauro Forghieri’s new for 1970 car, the ‘clean-sheet, Flat-12 engined 312B…

Mauro Forghieri’s Ferrari 312B was one of the most beautifully integrated Ferrari’s ever built, whilst much is made of the engine the success of the car was about far more. Doug Nye; ‘The 312B…was quite the best integrated 3 litre F1 package yet created. It would remain the best packaged of all Ferrari’s until the Postlethwaite 156 appeared in 1985’ he said writing in 1986. I always thought the 312T/T2 were pretty handy bits of integrated kit, but the point is, the car was a beautifully designed and executed car!

The talented Modenese born engineer saw at close hand as an at thecircuit race-engineer the success of the Lotus 49 and its imitators, the engine beautifully integrated with the chassis and the powerful, torquey, compact, relatively frugal and reliable nature of the Cosworth DFV itself. The engines basic dimensions and valve angles gave instruction to a whole generation of engine designers.

The suspension of the competition were all period conventional; wishbones/wishbones or rocker/wishbones at the front and single top-link, lower wishbones and radius rods for fore and aft location. The 312B followed that course.

Aerodynamics were still a black art but the CSI’s mandated lower wings meant airflow to the critical rear wing needed thought as the wing could no longer be mounted high in ‘clean air’. Remember, at the time traction was important, the cars had a wonderful surplus of power over grip.In the end that problem solved as much by tyre alchemy as wings let alone the 1969 4WD blind-alley of which Ferrari was not a part.

A 12 cylinder engine was a ‘Ferrari given’. Forghieri’s challenge was to unlock sufficient power to combat the DFV despite the inherent packaging issues of the longer engine and frictional losses and other bottom end shortcomings which were such problems in the existing V12.

Forghieri’s chassis was another of Ferrari’s ‘aero constructions’. They were not monocoques in the British sense but rather a tubular internal frame stiffened by riveted on ‘ally panels. Not a problem, Ron Tauranac’s old-fashioned spaceframe BT26’s were race winning GP cars in 1969 until effectively outlawed by the ‘bag tank’ rules of 1970.

The clever bit, ‘praps learning from the DFV’s simple chassis mounts mandated by Lotus designer Colin Chapman to Cosworth’s Keith Duckworth was the use of a ‘beam’ aft of the usual drivers bulkhead to which the engine mounted. This provided a very stiff structure but also very good, better than all other cars in 1970, airflow to the rear wing. It promised more downforce and therefore grip for less angle, drag, than the other cars.

Engineers Forghieri, Rocchi and Bussi’s 3 litre Flat-12 engine was conceived in that horizontally opposed configuration to get the cars centre of gravity low and get the engine out of the airstream to the wing. The need for lower frictional losses was met by the use of just 4, the old V12 had 7, main bearings. The design used  2 plain bearings in its centre and ball bearing races at each end.

Bore and stroke were 78.5mm x 51.5mm, vastly oversquare, for a capacity of 2991cc. Four overhead camshafts and 4 valves per cylinder were used, the heads evolved from ’69 V12 practice. Lucas fuel injection was carried over onto the new engine. The cams were driven by gears  from the crank’s nose.

Doug Nye; ‘The light alloy block was cast in 2 parts and united on a crankshaft centreline bolted flange…Light alloy cylinder liners were used, cooled by water circulation at their upper ends, by oil circulation down below. The crankshaft was machined from a steel forging, each of its six crankpins carrying two con-rods. The crankshaft nose gear drove alternator, ignition distributor and and fuel metering unit via gears and pinions. The crank tail drove the valvegear train. A tiny flywheel assembly incorporated a rubber vibration damper. Forged titanium con-rods were used…and Mahle forged aluminium pistons…a single oil pressure pump was driven off the rear of the RH cylinder timing gear fed the oil filter mounted behind the fuel metering unit.’

Amon watched the jewel of a car evolve at Maranello, it was with a great deal of optimism that he approached his early tests at Modena.

Right from the start he and Forghieri were happy with the chassis, the sort of balance they achieved with the earlier V12’s was still present. The car was lighter, was good under brakes had good traction and top speed for as long as the new, powerful engine lasted…

With Chris in the car the 312B had a series of monumental, catastrophic engine failures due to piston, crankshaft and lubrication problems. Amon; ‘I could feel that it was tremendously strong and powerful during those early tests, but it kept flying apart, i thought hell i can’t stand any more of this…’

After one of these sessions in August Chris said ‘enough’ and decided to leave the team.

Its ironic that Amon made the decision to leave due to the early failures of an engine which became a paragon of powerful reliability for a decade winning 3 drivers, 4 manufacturers and 1 sportscar championship for the Scuderia. Its performance was only compromised by its low/bulky architecture, a strength but an impediment in the ‘wing car ‘ era when the engine took space needed for ground-effect tunnels.

The engines bottom end failings were resolved by building a tilting dyno-bed at Maranello  to reproduce oil surge in corners. The crank torsional issues were sorted by the addition of a Pirelli cushion coupling between the crank and flywheel. In this form the 1970 spec engine developed 460bhp from 11500-11700 rpm rising to 510bhp@12000 rpm in 1979/80.

But for Chris it was all too much, he could see another season of Ferrari DNF’s caused by the repeated engine failures which had cost him victory or good placings on so many occasions. He saw his immediate future best served by driving a Ford Cosworth DFV powered car, the dominant engine of the time, so off to the nascent March concern he went.

He hadn’t burned his Ferrari bridges though, he was invited to be a member of the teams 512S sportscar squad in 1970…but Enzo Ferrari did say to the Kiwi that he, Ferrari, would win a race before Chris did!

image

Ickx, having made a smart move to Brabham in 1969 came back to Maranello for 1970 as ‘numero uno’ and was unlucky in some ways, in a season of great cars, not to win the title in the 312B!

The 312B came on strong, all issues solved in the second half of the season, the car won in Austria, Mexico and Canada for Ickx and at Monza for Regazzoni. Had the car started the season as well as it finished, noting Rindt’s death at Monza took out the seasons fastest combination, Ickx would have won the title. Mind you, there are plenty of new cars down the years that if they had reliability from the start of the season would have taken the title.

image

This group of shots (the one above and those at Modena below, all are undated sadly) are included for the sake of completeness; they are all of the same session. They show the beauty of this incredibly good, important for Ferrari car.

The photos convey a certain sense of calm as well, despite the problems which were apparent with the engine from the start. Apart from Chris of course, i am sure he felt far from calm trying to best assess his short and longer term options!

Driving careers are fickle things; he felt he had to seize the moment having in his mind stayed at Ferrari a season too long. Hindsight is brilliant of course, in fact he stayed a season too little, his testing skills may well have meant the car started the season better prepared than it did. Ickx wasn’t a noted test driver and new-boys to F1 Regazzoni and Giunti weren’t in a position to make the contribution Chris could and had made since 1967…

Amon Post Ferrari…

This article is not about Amon’s career, rather Ferrari elements of it. What follows is not a full summary of the balance of his wonderful career.

For Chris 1970 was frustrating!

The March 701 was not the best car of the season but both he and Jackie Stewart in Ken Tyrrell’s car ‘made it sing’. Stewart took a Spanish GP win and Chris the BRDC International Trophy at Silverstone, an F1 win but not the GP win he sought.

He came close to that in a titanic battle with Pedro Rodriguez’ BRM P153 at Spa in a test of the brave, bold, skilful and precise, just coming second.

He proved as quick as anyone in 1970, again. His record head to head in the 10 Championship GP’s he and Stewart raced the 701, the Scot in a Dunlop rather than Firestone shod car was 8/2 in Stewart’s favour. In all but 2 occasions Chris was only 1 or 2 grid slots behind Stewart who was arguably the best driver in the world at the time if not its fastest. Until his death most would argue that was Jochen Rindt. There is little doubt the Tyrrell 701 was a better prepared car than Amon’s March works car. The point to take here is that Amon was ‘right thereabouts’ with the best driver in the world at the time.

amon march

If the departure from Ferrari was not strategically the right one for all the reasons outlined earlier in the article, the departure to the new March outfit was a ‘leap of faith’ largely i suspect in designer Robin Herd which provided a competitive Cosworth powered car if not the quickest one. Amon knew Herd from their March days, Robin designed the first McLaren F1 car, the M2B and the ’67 CanAm Championship winning M6A Chev.

March were a company whose very successful raison d’etre was the construction and sale of production racing cars, its works teams secondary considerations. Its not hard in that context to work out what Max Mosley and Robin Herd’s prime focus was in 1970; to win in FF, F3 and F2 to flog cars for the coming year. Chris signed relatively early for March, before he knew they were selling 701′ s to ‘every man and his dog’ including the 1969 world champion for 1970. In 1970 Amon, Siffert, Stewart, Servoz-Gavin, Cevert, Peterson, Andretti and others raced 701’s. Works drivers Amon and Siffert didn’t have the cars to themselves.

Brabham, McLaren and BRM would have been better places to be in 1970 than March. Not that BRM was an attractive option in 1969.

Chris joined Matra who made him an offer he couldn’t refuse, back to a V12 for 1971 and 1972, taking a Non-Championship GP win in Argentina in 1971 and again lead races more than once only to experience car failures or punctures.

During 1972 Matra were mainly a single-car entry for Amon its focus increasingly on Endurance Racing success.

Tecno in 1973 was a disaster but Chris raced a third Tyrrell in Canada (Q11 2 slots behind Stewart in the unfamiliar car and 10th in the race) and the US (Q12 at the time the team withdrew from the race) for Tyrrell but not converting that into a 1974 drive after the death of Francois Cevert and retirement of Jackie Stewart at Watkins Glen.

His own Amon F1 car was also a disaster in 1974, a project commenced after a return to March in ’74 ‘evaporated’ over the Christmas New Year period seemingly after a failure in communication between Max Mosley and Chris. An engine development business with ex-BRM engineer Aubrey Woods also cost the Kiwi a lot of money. Looking at Chris’ career and some of the decisions suggests he needed a decent business manager, or a better one if he had one!

In 1975 he raced  the Talon MR1 Chev F5000 (nee McRae GM2) in the Tasman Series and in the US showing he had lost none of his skill despite a car not as good as the ubiquitous, highly developed Lola T332’s.

The only time i saw Chris race was in the final round of the ’75 Tasman at Sandown in February, he did the full series in one of Jack McCormack’s Talons, not the ‘fastest tool in the shed’ but Chris made the car sizzle despite junk engines which failed 3 times. He took a win at Teretonga, the final Kiwi round and was quick everywhere whilst the car stayed together.

I was a starstruck teenager who didn’t stray too far from his pit the whole weekend. On circuit what was impressive was his speed which was deceptive. He drove the car in a very ‘neutral’ fashion through the slow/medium corners where so many others were ‘tail out’. Across the top of ‘Marlboro Country’ a fast entry quicker corner his carrying speed and control was a joy to watch as was his precision under brakes into ‘Dandy Road’. I still recall the toe/heel too; on the brakes late and a change down late as well, a short/few revs blip at the throttle, easy on the DG300 box. A pro.

‘Auto Actions’ Paul Harrington gets the gen from Amon, Sandown Tasman ’75 practice Saturday, looks like its tough going! McRae GM2/Talon MR1 clones lovely cars (M Bisset)

Late in 1975 he had some drives of Mo Nunn’s Ensign GP cars, he and Nunn developed these pretty, effective cars into machines which shaded many of the big budget teams in 1976.

He was 10th on the Spanish GP grid, finishing 5th, 8th on the Zolder grid but lost a wheel and flipped the car emerging unscathed in the race. At Monaco he was Q12 and 13th. At Anderstorp he was a terrific 3rd on the grid but crashed out of 4th on lap 39 when the cars suspension failed.

Chris missed the French GP injured after Sweden, Patrick Neve qualified the car 26th, perhaps more indicative of the machines pace without an ‘ace’ at the wheel…

At Silverstone for the British GP, Chris qualified 6th, this time a water leak the cause of a DNF.

The problems of a low budget team in terms of design and preparation were clear, Chris decided he had ‘had enough’ of GP racing in this way and elected not to take the re-start of the German GP after Niki Lauda’s accident. The risk of something breaking on that circuit in that car was simply too great.

1976 showed he had lost none of his sublime, deceptively fast skill, speed and testing ability. He was still only 33 despite having his first Championship GP drive in 1963.

Amon’s last pro drive. Mont Tremblant CanAm 12 June 1977 in Walter Wolf’s Wolf Dallara WD1 Chev, grid 2 and DNF. Race won by Klauser’s Schkee Chev (Bob Harmeyer)

Amon’s last race was in Walter Wolf’s single-seat Can Am car in 1977 before saying ‘enough’, recommending Gilles Villeneuve for the ride before returning to his native New Zealand and farming at Bulls in the ‘Land of The Long White Clouds’ North Island. He sold the property some years ago but is not too far from the local racing scene and maintains a long-standing commercial relationship with Toyota.

Chris Amon had a career most of us can only dream about, life is all about the decisions we take, perhaps the decision to leave Ferrari in 1969 was the worst he ever made but in the same circumstances i suspect many of us would have made the same call.

To me though he should be remembered for what he achieved rather than what he didn’t: wins at Le Mans, Daytona 24 Hours, Monza 1000Km, a Tasman Championship, NZ (2) and Australian GP wins against some of the best drivers in the world, two non-championship F1 races and many individual race wins and the respect and fear of his peers. From 1967 to 1972 he was in the top 10 drivers in the world, for some of those years top 5.

Bot wow, Amon in a 312B in 1970, if only…

Jackie Stewart passes the burning molten alloy remains of Jackie Oliver’s BRM P153 and Jacky Ickx’ Ferrari 312B, fortunately both drivers escaped with only minor injuries, burns in Ickx’ case, lucky, it could have been much worse…

On the first of the 90 lap 19 April 1970 event Oliver had a suspension failure at the Ciudalcampo, Jarama, Madrid circuit, ploughing into Ickx and puncturing his fuel tank. The other P153 BRM of Pedro Rodriguez was withdrawn as a precautionary measure, Ollie reported stub axle failure as the accident’s cause.

The soldier, not a marshall puts Ickx’ overalls fire out. At this stage foam is being sprayed on the car fire but the foam extinguishers were soon emptied leaving water only, the impact on the molten magnesium componentry was to make the fire worse. (Automobile Year 18)

Jack Brabham’s Brabham BT33 Ford was on pole, reinforcing the speed of Ron Tauranac’s first monocoque GP contender, but Jackie Stewart won the race in one of his least favourite cars, the March 701 Ford.

The accident happened at the ‘Esses Bugatti’, a stub axle failed and Oliver’s BRM rammed Ickx’ Ferrari puncturing its fuel tanks and releasing 45 gallons of avgas, a similar amount aboard the BRM. Oliver got out quickly, Ickx finally emerged with his overalls on fire, the flames were put out by a soldier. Ickx suffered as a result of keeping his fuel soaked overalls on.

‘The accident created race havoc, not only the visibility being dangerously reduced for drivers…but the flaming petrol constituted another hazard. The fire-fighting was abysmal, vast quantities of water being hosed on the flames for a long time-a procedure which caused the magnesium elements to ‘gas’ and flare up time and time again. The BRM was still burning at the end of the race, but miraculously no-one was hurt’ the Automobile Year race report said.

Stewart didn’t have the race to himself; he initially pulled away from Brabham and Hulme, electronic dramas causing the Kiwi’s demise. Despite spinning twice Jack chased Stewart and Pescarolo, taking second when the Frenchman’s Matra V12 seized, he was five seconds behind JYS. Only a few metres separated them when Brabham’s Ford Cosworth failed, allowing Jackie to ease off to take victory.

Bruce McLaren was second, McLaren M14A and Mario Andretti in another privately entered March 701, third.

Jarama 1970 was also notable for the race debut of Chapman’s latest design the Lotus 72.

Jochen Rindt qualified his 8th, John Miles in the sister car did not make the cut. Rindt was out of the race on lap 8 with ignition failure.

It would take intensive development by Colin Chapman and his team to make the car competitive, the cars monocoques had to be ‘unpicked’ to make the suspension changes to eliminate a lot of the anti-dive/squat geometry and many other modifications but by June they had a winning car; victorious for Rindt in the sad Dutch Grand Prix, unfortunately the fire on that day had far more serious, fatal consequences for Piers Courage and his De Tomaso 505 Ford.

The sad reality of days like Jarama and Zandvoort in 1970, look how ill equipped in terms of fire protective clothing the marshalls are in the photos above, was the acceptance that safety standards in every respect; circuits, car construction and race support services had to improve to societal levels of acceptability. Thankfully we are on a different level in every respect today…

Momo was founded in 1964 by Gianpiero Moretti. He commissioned a local craftsman to produce a custom steering wheel for his racer, this first Momo steering wheel had a superior, thicker grip compared to other racing steering wheels of the day.

Other drivers quickly noticed Moretti’s new ’tiller’ and wanted one, so it started to gain fame within the racing community. The new Momo steering wheel caught the attention of Ferrari driver, John Surtees, who wanted one for his Ferrari 158 GP car, the car in which he won the world title in 1964. https://primotipo.com/2014/11/30/john-surtees-world-champion-50-years-ago/

Moretti created the company ‘Momo’ short for ‘Moretti Monza’ to make steering wheels commercially. Initially his focus was on racing but in the 1970s, the company developed new product lines.

Momo started  production of light alloy wheels and steering wheels for road cars, both for the aftermarket sector and supplying car manufacturers, initially Ferrari but others followed including Aston Martin, Fiat, Honda, Mazda, Mitsubishi, Nissan, Opel, Porsche, Peugeot, Renault, Subaru and others.

I reckon the first Momo i saw was in a cockpit shot of an F1 Ferrari 312B. Wow, it looked good! I was a secondary student at the time, it took me a few years to buy a road car, there were not too many other Cortina GT’s in the Monash University carpark with a Momo steering wheel. As one of my mates said the Momo was worth more then the ‘maroon rocket’ itself, which was an accurate call! Three Momo’s over time graced a succession of Alfa’s, a BMW 325is and a Carrera 3.2. My Van Diemen RF86 Formula Ford is fitted with one ex-factory. Things of beauty aren’t they? And function.

Whilst a Momo fan i never knew anything about the company’s history, despite being aware of Moretti’s racing exploits to an extent, its been interesting to do some simple research.

Momo continued its involvement in motor racing with success; in 1983 Brabham won the F1 World Championship, their car Momo equipped with light alloy wheels as well as a suede steering wheel as depicted in the first photo above. In 1998, Moretti won the Rolex 24 Hours of Daytona, the 12 Hours of Sebring, and the 6 Hours Watkins Glen driving a Ferrari 333 SP.

Mario Andretti, Ayrton Senna, Nigel Mansell, Nelson Piquet, Michele Alboreto, Michael Schumacher and earlier, Niki Lauda, Jackie Stewart and Clay Regazzoni won races with Momo steering wheels.

In 1995 Gianpiero Moretti sold Momo to Breed Technologies, an American industrial group which produced airbag systems and steering wheels. Breed Technologies, in turn was acquired by the Carlyle Management Group, a private equity fund. Recently, ‘Momo was bought by a group of investors with a passion for the brand, its heritage and its products and a desire to grow the company back to its roots’, the company website says.

Momo is still focused on light alloy road wheels, but has also continued to develop racing products, an example the supply of steering wheels for the GP2 Championships in Europe and Asia.

Twin radius rods at rear in evidence. Single top link, and lower wishbone also used at rear. Well protected Lucas fuel injection trumpets, and low nature of engine clear (R Schlegelmilch)

Jacky Ickx awaits the start of the Belgian Grand Prix, he finished eighth amongst a fantastic battle between Pedro Rodriguez and Chris Amon on this spectacular, fast and oh-so-dangerous classic circuit in the Ardennes…

Amon left Ferrari at the end of 1969 , a team he adored and had raced for since 1967. He had been very competitive throughout in F1, Sports Prototypes, and the Tasman Series, but the Championship F1 victory he sought had eluded him.

spa 1970

Spa vista 1970 (Bruce Thomas)

Mauro Forghieri designed the all-new 312B for 1970…

The core of the design was a horizontally opposed 12 cylinder engine utilising only 4 main bearings to minimise power-sapping frictional losses. The ‘Boxer’ engine layout allowed a very low centre of gravity and cleaner airflow for the rear wing amongst other benefits.

boxer

Engine ‘Type 001’. 180 degree, DOHC, four valve, Lucas fuel injected ‘Flat 12’. Distributor, coil and Dinoplx electronic ignition. Very oversquare at 78.5×51.5 Bore/Stroke, 2991cc. 11.8:1 compression ratio, circa 460BHP at 12000RPM in 1970, rising to over 525BHP throughout the 70’s (unattributed)

Chris tested the car late in 1969, several massive engine failures convinced him to leave the team to drive a competitive car powered by the dominant, powerful and reliable Ford Cosworth DFV V8. And so it was that his Cosworth DFV powered March was beaten throughout the season by the 312B’s and in Belgium by the BRM P153 V12 of Rodriguez.

Chris’ Ferrari departure proved to be another of Amon’s poor timing decisions, his capacity for being in the ‘right place at the wrong time’ was legendary. Forghieri’s design was both reliable and fast in 1970, Ickx won three races and newcomer Clay Regazzoni one- Ferrari narrowly missed the drivers and constructors titles to Jochen Rindt, posthumously, and Lotus.

In fact the engine was brilliant, one of the greatest in F1, powering cars which took Niki Lauda (1975 and 1977), and Jody Scheckter (1979) to world titles, and in endurance form winning all the classic endurance events but the two 24 Hour races at Le Mans and Daytona. In its early form the DOHC, four valve, Lucas injected, 2991cc engine developed around 460BHP at a time the DFV developed circa 435BHP.

The chassis of the 312B was also new and whilst not a ‘full-monocoque’, the combination of aluminium reinforced space-frame tubing was very effective and forgiving to drive.

Newcomer Ignazio Giunti was the best placed Belgian GP 312B in fourth, Ickx having a variety of problems. The race was won by Rodriguez by a second from Amon with Jean Pierre Beltoise third, a further 1.43 minutes adrift, such was the pace of Pedro and Chris.

Amon set a new lap record in his chase of Rodriguez at 152MPH, but Pedro was ‘Spa fit’ having set a 160MPH lap in a 4.5 litre flat 12 Porsche 917 the week before…oh to have seen either race!

There was a chicane at Malmedy for the Grand Prix which was unused during the 1000 Km classic but all the same, 160MPH was the fastest ever lap-time of a road circuit anywhere in the world at the time.

Out into the Ardennes Forest …Rindt from Ickx, Beltoise, Brabham in the distance and the yellow speck Peterson…Lotus 49 DFV, Ferrari 312B, Matra MS120 V12, Brabham BT33 DFV, and March 701 DFV (unattributed)

But Pedro Rodriguez won the day in the BRM P153 V12…over the years there have been rumours the BRM engine was ‘fat’ that day, but these have been scotched by Doug Nye amongst others. Also, Pedro was supreme at Spa and Tony Southgates’ P153 and ’71 P160 BRM’s were fast, if not always reliable race-winners (unattributed)
