Son Of Lobster Claw – Trojan Cosworth T103 #T103/1

After the successes of the 1973 Trojan T101 Formula 5000 car, particularly in the hands of Jody Schekter in the USA, the company Chairman Peter Agg asked Ron Tauranac to design an all new car for 1974 which would be suitable for F5000, the T102, and Formula 1, the T103 although the Chevy V8 in the former would not be able to be fitted as a fully stressed member as the Ford Cosworth DFV used to power the latter.

Both the T102 and T103, seen above at last years Silverstone Classic, bore a strong resemblance to the Brabham BT34 Lobster Claw formula one car which Ron designed for the 1971 season.

Powered by the, as good as, ubiquitous Ford Cosworth DFV with an equally, as good as, ubiquitous Hewland DG300 gearbox the T103 attracted a minimum of sponsorship from Suzuki GB and Australian Tim Schenken was signed up to drive the car.

Like the Amon Cosworth AF101 I looked at last week the Trojan T103 made it’s debut at the 1974 Spanish Grand Prix where Tim qualified 25th, 2 spots behind Amon, but stayed in the race for 54 more laps than Chris before spinning off on oil on lap 76, eight laps early, to be classified 14th.

At the Belgian Grand Prix Tim brought the car home 10th and at Monaco Tim qualified 24th on the 25 car grid only to be involved in an incident that removed seven cars from the race on the opening lap. The team was refused an entry for the Swedish Grand Prix, failed to qualify for the Dutch Grand Prix, missed the French Grand Prix and turned up at the British Grand Prix with a new cockpit surround and Ferrari 312 B3 style single piece front wing.

Tim qualified 25th for the British Grand Prix but but was sidelined with a suspension problem on lap 6. Tim and the Trojan proved unequal to the task of qualifying for the German Grand Prix at the Nurburgring, but bounced back by qualifying 19th in Austria where he finished a season equal high 10th. The cars final appearance before the money ran out was at the Italian Grand Prix where Tim qualified 20th and completed 15 laps before the gearbox cried enough.

That was pretty much the end of Trojan too, a company that founded in 1914 survived as a manufacturer in it’s own right until the the 1960’s when it started manufacturing first Heinkel bubble cars, then Elva sports racing cars and later McLaren Sports and open wheel racing cars under licence and then manufacturing a hand full of open wheelers of it’s own devising. The company was not dissolved until 2013.

Tim Schenken’s final Grand Prix appearance came in the 1974 US Grand Prix where he failed to qualify the unloved Lotus 76 27th but took to the grid when it looked like Mario Andretti’s Parnelli would not start but eventually turned up late grid to take his rightful place. Tim took the start only to be disqualified.

Tim eventually hooked up with Howden Ganley to found Tiga a successful company making racing cars for the junior open wheel and sportscar classes. A Tiga chassis tub was started for a Formula One car but it was never finished. Tiga would also become a successful Group C2 and IMSA Lights manufacturer.

The T103 is seen being driven by owner Phillipe Bonny at last years Silverstone Classic above.

Thanks for joining me on this “Son of Lobster Claw” edition of “Gettin’ a li’l psycho on tyres”, I hope you will join me again tomorrow for Maserati Monday. Don’t for get to come back now !

Flint Stones – Surtees Ford TS14A #03 & #04

In 1972 new regulations were rushed through for Formula One cars mandating deformable structures be fitted to the sides of the vehicles in an attempt to reduce the risk of cars bursting into flames in the event of a side impact. Two sets of regulations were written one for more or less immediate effect in 1972 and a seperate more robust set of deformable structures regulations for 1973.

Towards the end of the 1972 season John Surtees 1973 challenger was the first to appear at the 1972 Italian Grand Prix built to the latest safety regulations. John qualified 19th and retired from what turned out to be his final Grand Prix race after 113 starts over 13 seasons which included six wins and one World Drivers Championship. Tim Schenken qualified 31st in the final race of the 1972 season at Watkins Glen but also retired.

During the off season John Surtees was caught on the hop with the wrong tyre contract after Firestone which had been used by the 1972 Champions Emerson Fittipaldi and Lotus were to quit the sport at the end of 1973 and would not be developing their tyres any further through the 1973 season while their supply contracts to the likes of BRM, Surtees and Williams ran out.

So with little hope of achieving any worth results Surtees ploughed on through the 1973 season. Nominal team leader Mike Hailwood managed a season best qualification of 6th in the 1973 US Grand Prix, using the #04 chassis seen carrying the #23 race number here at Wings and Wheels at Dunsfold Aerodrome, and a best season race finish non points 7th in the 1973 Italian Grand Prix.

Team mate Carlos Pace meanwhile scored a season high 5th in the 1973 Italian Grand Prix and finished 4th in the German Grand Prix and 3rd in the following Austrian Grand Prix as well as taking fastest lap on the way to both points scoring finishes. Carlos finished 11th in the Drivers Championship and Surtees 9th in the 1973 Constructors championship. For 1974 Surtees built two new TS16 cars to be driven by Carlos Pace and Jochen Mass. When sponsorship for the season failed to materialise Carlos found his way into a drive at Brabham.

Mike Hailwood drove a third works car for McLaren in 1974 until an accident at the Nurburgring prematurely ended his career. Jochen Mass would end up taking over the drive at the end of 1974.

The low point for the Surtees team in 1973 came at the British Grand Prix where they had three cars of Hailwood, Pace and Mass all wiped out in the first lap collision at Woodcote Corner that eliminated a six additional vehicles see this linked clip, note that thanks to the new deformable structures no fire’s were started in the accident.

Electronic Clutch & Four Pedals – Lotus Ford 76 #76/1 (JPS 9)

I remember when I first set eyes on the publicity photo’s of the Lotus 76, my reaction was an instant WOW ! The two team cars which had been completed a little late were to replace the venerable Lotus 72 and be driven by Ronnie Peterson and Jacky Ickx in the 1974 season starting at the South African Grand Prix.

The new car was intended to be slimmer and lighter than the Lotus 72 which had helped Jochen Rindt and Emerson Fittipaldi to win World Drivers Championships in 1970 and 1972 and helped Lotus secure the World Constructors Championship in 1970, ’72 and ’73.

Innovations on the car included an electronic clutch operated by a button on the gear stick, except when starting from rest for smoother gear changes. Two brake pedals were fitted either side of the steering column operating a single split leaver to encourage left foot breaking to minimise the upset of the balance of the car when approaching corners and two thin, for the period, rear wings mounted one above the other.

Much to the consternation of the press and Lotus fans Colin Chapman sold the naming rights to the Lotus 76 which for the 1974 season was to be known as a John Player Special the chassis number of the car seen here at Goodwood was referred to as JPS 9 though the chassis was unofficially referred to in the press and by enthusiasts as 76/1.

A pattern of retirements set in at the South African GP which was to repeat itself until by the Monaco Grand Prix Lotus Team had decided to revive the Lotus 72 which Ronnie Peterson promptly drove to the first of 3 against the odds victories during the season.

Development of Lotus 76 was split between the ageing Lotus 72 during 1974, to generate more down force larger front wings and the larger rear wing of the Lotus 72 were fitted to the Lotus 76 which appeared in Belgium.

With the 76 having been observed to be popping wheelies after additional down force had been added the front nose cone was then replaced with a cut down version from the Lotus 72, the radiators moved from ahead of the rear wheels to behind the front wheels and horizontal boards were added along the top of chassis between the front and rear wheels as seen in this linked photo of 76/2 (JPS 10) at the 1974 British GP.

By now the 76 was being taken to races purely in case of an emergency and during practice of the 1974 German Grand Prix such such an emergency arose after Ronnie Peterson crashed Lotus 72/8. The team had no option but to press the by now overweight and unloved 76 back into service and did so by grafting the rear suspension engine and gearbox from the wrecked 72 onto the back of 76/2 (JPS 10). With the car now looking more like it’s predecessor Lotus 72 than a Lotus 76 Ronnie Peterson recorded the 76’s only finish with a forth place on the toughest circuit on the calender !

After confusion about Mario Andretti starting from 3rd place in the 1974 US Grand Prix, in his Parnelli, third Lotus driver Tim Schenken took the flag of the 1974 US Grand Prix only to be disqualified for being outside the top 26 qualifiers as Andretti had managed to get his car onto the grid, ironically only to be also disqualified for a push start away from the line ! This was Schenken’s and the Lotus 76 last Grand Prix start.

However this was not quite the end of the Lotus 76 story, Colin Chapman was a long time member of a motor club in North London and after a little badgering for ‘something a bit quick’ from fellow long time member, David Render, who participated in Sprints and Hillclimbs, Colin relented and told his friend to turn up at the Lotus factory at Hethel with a trailer.

Lotus 76, Goodwood FoS

When David turned up at Hethel early in 1976 he saw this huge black car with twin wings and asked who is this for ? He was quite surprised to learn that it was intended for him !

David drove what is believed to be 76/2 (JPS 10), in original lightweight form, for 2 years and among many victories won the 1976 Brighton Speed Trials when the event was run over a standing kilometer 0.6 miles and clocked a time of 18.77 seconds reaching a 118 mph as he crossed the line.

Lotus 76, Goodwood FoS

At a recent talk, David gave to the Bristol Pegasus Motor Club, he related how on finding the car suffered from terrible understeer / push he added a lump of lead, taken from his old Allard trials car, beneath the nose cone of the 76 and that solved the problem, though he never told Colin ‘Added Lightness’ Chapman what he had done.

The car featured in today’s post 76/1 (JPS 9) seen at Goodwood Festival of Speed and at the 2011 Silverstone Classic belongs to Andrew Beaumont. According to Classic Team Lotus during the first of two races at the 2011 Silverstone Classic meeting Andrew’s double rear wing got savaged, but it did not have much detriment to the performance of the car and he finished 22nd.

John Barnard eventually perfected a semi automatic electronic clutch and gearshift mechanism with a steering wheel mounted paddle shift for the 1989 Ferrari 640 which won first time out at the Brazilian GP in the hands of Nigel Mansell. This system is now de riguer in almost all top line racing cars.

My thanks to MCS, Gregor Marshall, and Tim Murray on the Lotus 76 thread at The Nostlgia Thread who helped identify a Lotus 76 at the Abbaye de Stavelot Museum as the possible home of the second Lotus 76 chassis #76/2 (JPS10).

Thanks for joining me on this ‘Electronic Clutch & Four Pedals’ edition of ‘Gettin’ a li’l psycho on tyres’ I hope you will join me again tomorrow when I’ll be looking at last weekend’s Auto Italia Day at Brooklands. Don’t forget to come back now !
