European Highlights – Goodwood Festival Of Speed

As the years roll by going to Goodwood Festival Of Speed is more and more like going to the best toy shop in the world with more and more cool stuff to be found every year, this was my sixth visit since 2009 and already having completely failed to compose my thoughts about some of the highlights of this years event, as I write this I am looking forward to next years event !

Kremer K8, Derek Bell, Goodwood Festival Of Speed,

One of the highlights of the event was a collection of 15 vehicles celebrating the career of five time Le Mans 24 hour winner, 3 time Daytona 24 Hour winner and twice World Sports Car Champion Derek Bell, seen above in his 1994 Le Mans 24 Hour entry the Porsche powered Kremer K8 with which he Robin Donovan and Jürgen Lässig qualified 2nd and finished 6th.

Audi Sport Quattro S1 E2, Hannu Mikkola, Goodwood Festival Of Speed,

The Audi Sport Quattro S1 E2 was Audi’s final Group B evolution producing an initial 500hp in 1985 when Walter Röhrl and Christian Geistdörfer won the San Remo Rally and over 600hp when Walter Röhrl drove one to victory on Pikes Peak in 1987, above 73 year old Rally Legend Hannu Mikkola show’s he still has no problem handling the cars 0-60mph in 3.1 seconds performance.

Jaguar XJ12C, Andy Rouse, Goodwood Festival Of Speed,

In the mid 1970’s one used to hope against hope that British Leyland would get it’s act together and thrash BMW in the European Touring Car Championship, but alas despite starting from pole in 6 from nine events the Jaguar XJ12C’s best result was a second place finish at the Nurburgring in 1977 with Derek Bell and Andy Rouse at the wheel, former works driver Andy Rouse is seen demonstrating the Jaguar Daimler Heritage Trust’s 1976 example above.

Lotus BRM 43, Andy Middlehurst, Goodwood Festival Of Speed,

While Lotus were waiting for the arrival of Ford’s DFV for the 1967 season Jim Clark had to make do with the woefully underpowered Climax powered 1965 Lotus 33 until the arrival of the BRM H16 powered Lotus 43 in time for the last three races of the 1966 season, the car was instantly quick qualifying 3rd at Monza, and 2nd in the USA and Mexico but also unreliable suffering gearbox failure at Monza and Mexico but the car with one of the most complex motor configurations on earth held together at Waltkins Glen where Jim Clark won scoring a fourth consecutive victory at the circuit for a BRM powered car, Andy Middlehurst is seen driving the 43 above.

Mercedes Benz 300 SLR, Sir Stirling Moss, Goodwood Festival Of Speed,

Mercedes Benz prepared for the 1955 World Sports Car Championship by building 9 300 SLR’s of the eight survivors seven were at Goodwood, above Sir Stirling Moss demonstrates chassis #0004/55 with which he and navigator Denis Jenkinson won the 1955 Mille Miglia ahead of the sister car #0003/55 driven by Juan Manuel Fangio.

FIAT S76, Duncan Pittaway, Goodwood Festival Of Speed,

Finally with a Herculean effort Duncan Pittaway got his recreation of a FIAT S76 to Goodwood last year, but did not dare try and start it. With help from Leonardo Sordi he has since got the car running and as can be seen above it is a wonderous sight to be hold as the 28.3 litres / 1,727 cui four cylinder motor belches flame from it’s monstrous exhaust stubs.

Thanks for joining me for this “European Highlights” edition of “Gettin’ a li’l psycho on tyres” I hope you will join me again tomorrow when I’ll be looking at some of the American Highlights at Goodwood. Don’t forget to come back now !

The Seriously Flared One – Porsche 911 Carrera RSR 3.0

Having won the 1970 and 1971 Le Mans 24 Hours and sports car championships with the short lived Porsche 917, Porsche had no suitable motor with which to compete in the top tear of sports car racing which mandated maximum displacement 3 litre / 183 cui motors, of which those designed for and adapted from Formula One dominated the overall honours from 1972 until 1975.

Porsche 911 RSR, Tour Britannia, Castle Combe

To meet the demand from customers running in the GT class Porsche embarked upon a programme of building RSR race cars based on the 911 shell for GT competition in 1973. Initially these cars came with a ‘duck tail’ and motors up to 2.8 litres to 178 cui. Peter Gregg and Hurley Haywood scored back to back overall victories at the Daytona 24 hours with this type of car in 1973 and 1975, and were joined by Dave Helmick in 1973 to win the Sebring 12 hours. Perhaps the single most famous victory for any RSR came on the epic Targa Florio where Herbert Müller and Gijs van Lennep won beating the 3 litre / 183 cui protoypes in the process.

By the end of 1973 the first RSR’s with 330hp 3 litre / 183 cui motors, coil springs replacing torsion bars, flared wheel arches housing wheels with centre locking nuts and ‘whale tales’ came onto the scene most notably in the first International Race of Champions (IROC) series. The first IROC series ran in the winter of ’73 and ’74 at Riverside and Daytona for which 12 identical Carrera 911 RSR 3.0’s, like the one seen in today’s photographs, were prepared for the likes of, Formula One champions; Emerson Fittipaldi and Denny Hulme, Indy 500 winners; Bobby Unser, AJ Foyt, Gordon Johncock and Mark Donohue, Can Am Champions; Peter Revson and George Follmer, NASCAR Champions; David Pearson, Bobby Allison and Richard Petty with USAC Champ Roger McKlusky. Mark Donohue won three of the series four races to become the first IROC Champion.

The RSR remained competitive in the Daytona and Sebring endurance classics until 1977. Haywood, John Graves and Helmick drove an RSR to victory at Daytona in ’77, with Al Holbert and Mike Keyser winning the ’76 race at Sebring then George Dyer and Brad Frissell repeating the feat in another RSR in ’77. In Europe Clemens Schickentanz is thought to have made over 75 starts with at least seven outright victories in RSR’s primarily for the Kremer Brothers.

In all 60 RSR 3.0’s were built by Porsche and many more 911’s have been upgraded to RSR spec since the models inception. RSR’s were still being raced regularly in front line competition into 1993 when an all new Carrera RSR was introduced with a 3.8 litre / 231 cui motor.

Porsche 911 RSR, Silverstone Classic

I do not have a history for the 1974 Martini liveried car featured today which, in the 2011 dated pictures, are seen at Castle Combe with Jeremy Cook and Mike Dowd who were taking part in the Tour Britannia, the 2012 and 2015 photo’s were taken at Silverstone Classic where Jeremy and Mike competed in the FIA Masters Historic Sports Car races, if you know anything more about this car please do not hesitate to chime in below.

Musical Spares – Porsche 962C #006

The Porsche 962 was built in two specs, the original was the 1984 IMSA GTP spec which was a variation of the dominant Group C Porsche 956 sports car first seen in 1982. The 962 differed in two important aspects from it’s Group C cousin. First the 962 had a longer wheel base so that the drivers feet were behind the center line of the front axle and second IMSA mandated a single turbo while the Group C 956 ran more powerful twin turbo’s.

Porsche 962C, Le Mans, France

For 1986 the FIA mandated that Group C cars should follow the lead set by IMSA and have the drivers feet behind the the center line of the front axle line while making no changes to the engine regulations so the more powerful Porsche 962C came into being sweeping all before it much as the 956 and 956B had done. Derek Bell became the first driver to successfully defend his World Sports Car Drivers Championship won driving a 956B in ’85 and 962C in ’86. In 1986 Derek also won the Le Mans 24 hours for the forth time sharing his 962C with Hans Joachim Stuck and Al Holbert, Derek was also awarded the MBE for services to motorsport, a Royal honour which even Porsche AG noted on the door of Dereks #17 car as seen above at Le Mans in 1987.

Porsche 962C, Le Mans, France

Going into Le Mans 1987 Derek Bell and Al Holbert were on a roll of three consecutive 24 hour race wins going back to Daytona ’86 where they shared an IMSA GTP 962 with Al Unser Jr. As mentioned above Bell and Holbert followed that up at Le Mans winning with Hans Stuck and made it a three peat of 24 hour victories at Daytona sharing Holberts Löwenbrau Porsche 962 with Unser Jr and Chip Robinson. Only a complete idiot would have bet against Bell, Stuck and Holbert claiming victory at Le Mans in 1987. The #17 chassis #006 seen in the rain above qualified 2nd on the grid by Hans Stuck next to the #18 chassis #008 which Bob Wollek qualified on pole.

Derek Bell, Hans Joachim Stuck, Le Mans, France

But the fourpeat of consecutive 24 hour victories very nearly did not happen, things started to go wrong for the works Porsche team a week before the race when Hans Stuck tested all the Le Mans cars at Porsche’s Weisach test facility. Stuck experienced a puncture while driving the car designated for his team mates Jochen Mass and Brilliant Bob Wollek. As a consequence Mass and Wollek were given the car designated as the race car for Stuck, Bell and Holbert chassis #008 while the ’86 winning trio took over the car designated for Vern Schuppan, Kees Nierop and Price Cobb chassis #006, today’s featured car, and the Schuppan, Nierop, Cobb combination were given the older chassis #002 which had been designated as a spare. Bell and Stuck are seen above returning from the new chicane an hour before the start of the race.

Porsche 962C, Le Mans, France

The next problem for the Porsche team occurred in practice when Price Cobb had an accident which wrote chassis #002 off during the first day of practice so that there were now only two works entered cars to challenge for the win, but as designer Norbert Singer observed ‘only one of them can win’. Schuppan, Nierop and Cobb all found rides in other cars.

Porsche 962C, Le Mans, France

An hour into the 1987 race it looked as if Jaguar who were at least 3 seconds slower than the lead Porsche in practice might pull off a remarkable win as they held first third and fifth. The Porsche cars were falling like a chain of domino’s with engine failures, something in the fuel was causing the latest in Bosch (ECU) electronic management systems to run the Porsche engines much too lean which resulted in engine failures for the pole sitting works car; 2 Joest Porsche 962C’s and a Kremer 962C.

Porsche 962C, Le Mans, France

Fortunately the #17 had managed to get into the pits to change to an older ECU before any permanent damage was done and 2nd placed Bell, Stuck and Holbert proceeded to pursue the lead Jaguar at break neck speed until midnight when it took the lead for the final time as the four 7 litre / 427 cui V12 Jaguar XJR 8LM’s started to fall by the wayside with a puncture, an accident, a cracked cylinder head and a missed gear change respectively.

Porsche 962C, Le Mans, France

The punctured #5 Jaguar driven by Win Percy had required an 80 minuet safety car period to clear up the debris in the dead of night as the Jaguar had been pitched at 200 mph into the barriers of the Mulasanne straight ripping off the gearbox and engine, Win Percy unlike his helmet was completely unscratched. The relentless pace at which the #17 Porsche had been chasing the Jaguars meant that Bell, Stuck and Holbert were way over their fuel allowance as the safety car period started but right back on schedule once the mess created by the Jaguar had been cleaned up.

By the end of the race Bell, Stuck and Holbert were 20 laps to the good; from the private Primagaz Competition 962C of Juergen Lässig, Pierre Yver and Bernard de Dryver; as they recorded their fifth, second and third Le Mans wins respectively, their second consecutively as a winning Le Mans trio and Bell and Holberts 4th consecutive 24 Hour race win. Porsche also recorded their seventh consecutive Le Mans win in 1987.

The following year things would not be so easy as Jaguar, who won the 1987 World Sports Car Championship and who’s driver Raul Bosel won the 1987 World Sports Car Drivers Championship took the fight even more convincingly to Porsche at Le Mans.

Chassis #006 was driven at Spa in 1986 by Jochen Mass and Bob Wollek on it’s debut where it was qualified third and finished 7th it’s only other race start was at Fuji where Holbert and Pescarolo started from 12th and retired with transmission problems. Prior to the Le Mans 24 hours #006 had primarily been used as a spare car at Jarama, Jerez, Monza and Silverstone in 1987. #006 was driven by Bob Wollek and Canadian Kees Nierop for the ’87 Le Mans test weekend where carrying the #17 it recorded the 2nd fastest time. After the 24 hour win in ’87 #006 returned to Le Mans in 1988 as a spare that was briefly used by Micheal Andretti in practice before it was retired for good.

1% Efficiency Gain – Porsche 935 K3 #00017

The dominating sports car of the mid 70’s to early 1980’s was the Porsche 935, built for a set of regulations known as Group 5. The 935 was based around the Porsche 911, the works factory team developed three distinct versions in ‘76, ‘77 and ’78 when the Moby Dick version marked the high tide of factory 935 development. Porsche also built a customer version of the 935 the 935/77A.

Meanwhile the Kremer Brothers set about developing their own 935, the K1, based on the Porsche 934 model, that was available for the technically less demanding Group 4 regulations in 1976. In 1977 the Kremer brothers acquired a customer 935 and in 1978 followed their own development path based on the 935/77A to develop the K2.

Porsche 935 K3 #00017, Palo Alto

For 1979 their K3 model featured over 100 detail changes from the standard customer 935 ’77 which included a lighter air to air intercooler in place of the hitherto ubiquitous air to water sytem, composite carbon fibre panels which saved 30 kgs / 62 lbs. The DM 400,000 K3 was thought to have been 1% more efficient than the standard customer 935 ’77 which over an endurance distance of 6, 12 or 24 hours would accrue to a handy advantage.

The K3 scored the 935 models only win at Le Mans in the hands of the Klaus Ludwig and the Whittington Brothers Don and Bill and a string of customers were soon knocking on the Kremer Brothers door in Cologne asking for copies.

Porsche 935 K3 #00017, Palo Alto

It is believed the Kremer Brothers built 13 K3’s and supplied kits to update older 935 models. I have not managed to ascertain if this 935 K3 is one of the Kremer brothers built models or one built up from a kit around a donor car, it carries the paint work of a vehicle belonging to Ted Field that was raced by Ted, Danny Ongias and Milt Minter in the Daytona 24 hours that came in 3rd from 5th on the grid.

Canepa Design are known to have recently restored such a car and if as seems highly probable this is the same vehicle the chassis number of this vehicle is # 00017.

My thanks to URY914 at The Nostalgia Forum for confirming that this car may have been converted to Trans Am spec and entered by John Klug Racing in 1983 and to Geoffey Horton who kindly sent me these photos from Palo Alto Concours d’Elegance.

Thank you for joining me on this Interscope edition of Gettin’ a lil’ psycho on tyres’, wishing you all a happy bank holiday Monday, I hope you will join me again tomorrow. Don’t forget to to come back now !
