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.

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.

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.

Unlimited Perfection – Porsche 917/30 #002

There are some cars that stand head and shoulders above all others in terms of their achievements in their particular fields of endeavour even though their period of dominance is short lived. One such is the Porsche 917/30 as perfected into the ultimate race car for the 1973 Can Am Challenge for Group 7 unlimited sportscars by Porsche AG, Roger Penske and his driver Mark Donohue.

Porsche 917/30, Goodwood Festival of Speed

The origins of the space frame chassis and flat 12 motor that power this model lie in the Porsche 917 Endurance Sports Car programme that got underway after an unexpected change in sports car regulations designed to prolong the competitive viability of the Ford GT40’s and Lola T70 Coupé’s powered by 5 litre / 302 cui motors. The change in the regulations mandating vehicles of which at least 25 examples had been built with up to 5 litre / 302 cui motors were seen as an open opportunity by the engineers at Porsche to build a car with a competitive life limited to just three seasons of endurance racing from 1969 to to 1971. In that time Porsche and it’s preferred teams transformed the 917 from an initial limp biscuit into a preeminent sports car that conquered almost every race in which it took part laying the foundation of Porsche’s endurance racing reputation that was unrivaled until sister company Audi took up the mantel at the beginning of the 21st century. The Porsche 917’s achievements included back to back Le Mans wins in 1970 and 1971, back to back World Sports Car Championships in the same years and celluloid immortalisation by none other than the undisputed celluloid King of Cool Steve McQueen thanks to his film Le Mans.

Porsche’s first foray into the world of unlimited Can Am racing came in 1970 with a couple of 917 predecessors in the form of the 3 litre / 183 cui flat 8 powered 908 Spyders for Swiss driver Jo Siffert and Britain’s Tony Dean. Siffert was soon given a Porsche 917 PA Spyder fitted with a 4.5 litre / 274 cui flat 12 motor with which he finished a season high 3rd for the marque at Bridgehampton on his way to 4th place in the 1969 Can Am Challenge. The following season Tony Dean in his 908 was the only regular Porsche representative and he took an unlikely but popular win at Road Atlanta on his way to 6th in the 1970 Can Am Challenge standings.

Several of the closed cockpit 917K’s taking part in the 1970 Watkins Glen 6 hour race took part in the following days Can Am race at the same circuit and Siffert with a 5 litre / 302 cui flat 12 motor finished second to Denny Hulme’s Chevy 7 litre / 427 cui powered McLaren M8D.

Vasek Polak Racing acquired Siffert’s 917 PA for Milt Minter in 1971 while Siffert had a new 917/10 with updated bodywork that included a large rear wing but was still running a 5 litre / 302 cui normally aspirated motor. Siffert scored two season high second places and finished 4th in the 1971 Can Am Challenge two spots ahead of Minter.

In 1972 Roger Penske became the works Porsche representative in Can Am with a pair of Porsche 917/10’s, now fitted with turbocharged 5 litre / 302 cui flat 12 motor’s Donohue finished 2nd in the opening round at Mosport but then broke a leg in a testing accident at Road Atlanta where George Follmer was hired at short notice to replace Mark. George won the race and four more that season to clinch the 1972 Can Am Challenge. Mark recovered to win a single race upon his return at the end of the season to finish 4th in the Challenge, behind Milt Minter who still had the old 917 PA fitted with the latest 917/10 body work and a variety of turbocharged and normally aspirated engines during the course of the season.

Porsche 917/30, Goodwood Festival of Speed

For 1973 Porsche, Penske and Mark worked on the definitive ultimate 917, today’s featured 917/30, which featured a longer wheel base and a turbocharged 5.4 litre / 329 cui flat twelve fitted with 2 spark plugs per cylinder that produced a conservative 1100hp, or up to 1500hp in qualifying trim with 39 psi / 2.7 bar of boost from the twin turbochargers.

Mark qualified on pole for all 8 races in the 1973 Can Am Challenge. In the first race at Mosport he finished a season low seventh, after tripping over a back maker which allowed Charlie Kemp to win driving the previous years Penske 917/10 model for Rinzler Racing. At Road Atlanta Mark experienced a fuel filler leak while leading forcing him to pit for the leak to be fixed. Mark rejoined the race to finish second to the other Rinzler Racing ex Penske 917/10 being driven by George Follmer.

Thereafter Mark won the remaining six races as he pleased to become the first Can Am Challenge winner to score points in all the challenge races. In 1974 the hitherto unlimited Group 7 cars were given their first restriction when the SCCA mandated a 3 miles per gallon fuel limit, this did not outlaw the 917/30 as is widely believed, in fact Roger Penske entered one of the 917/30’s for Brian Redman to drive at Mid Ohio.

Under strict instructions to use only the top three, of four, gears in order to minimise fuel consumption Brian qualified on pole and came home second, behind Jackie Oliver driving a Shadow DN4, after understeering, pushing, off the circuit during the race.

In 1975 Mark Donohue returned to the cockpit of a CAM2 sponsored 917/30 now fitted with twin inter coolers to raise the world closed circuit lap record from the 217 mph set by AJ Foyt, in his open wheel USAC Coyote, to 221 mph at Talladega Superspeedway. The record which was set in less than optimal dry conditions stood for two decades.

Today’s featured car seen at Goodwood Festival of Speed a couple of years ago is chassis 917/30 #002 which appears to have served primarily served as Mark Donohue’s spare for the 1973 season. Contemporary reports in Motor Sport suggest it was only raced at Watkins Glen after a suspension failure on Marks regular chassis #003 required #002 to be wheeled out for race duty, which included winning pole and leading from flag to flag to secure a 42 second victory over David Hobbs Carling Black Label Roy Woods Racing 1972 Mclaren Chevrolet M20.

917/30 #002, one of six 917/30’s built of which only three saw in period competition, now belongs to the Porsche Museum.

Balena Close, Poole, Dorset – Penske PC1 #001

After he had finished fabricating the Len Terry designed Eagle monocoques for All American Racers (AAR) in California, John Lambert returned to the Untied Kingdom and started a new business which was located on a small industrial estate outside Poole in Dorset where the rent was cheap. When Len Terry fell out with Frank Nichols they wound up Transatlantic Automotive Consultants based in Hastings where they had designed the AAR Eagle and Terry went to join Lambert, with whom he had worked at Lotus and AAR, in Poole starting a new business together called Design Auto.

In 1969 Len Terry started to design a series of stock block Formula 5000 open wheel cars called Leda’s, John Lambert looked after the construction of them in a facility off Balena Close on the Creekmore Industrial Estate on the outskirts of Poole, Dorset. When Leda Cars ran into financial difficulty they merged into the Malaya Garage Group in 1970. Three years later Malaya Garage Group did a deal with New Zealand racer Graham McRae selling the Leda Cars premises “lock, stock and barrel” with the cars manufactured now rebranded as McRae’s.

At around this time Roger “The Captain” Penske and Mark “Captain Nice” Donohue were experiencing many successes on the US racing scene which included three Trans Am championships, then only for manufacturers, driving the Captains Chevrolet Camaro in 1969 and AMC Javelins in 1970 and ’71.

In 1972 Mark won the Indy 500 in Roger Penske’s McLaren M16 and at the end of the year drove Penske’s McLaren M19 in the Canadian and US Grand Prix finishing a more than credible 3rd in his debut Grand Prix. The following year Mark and Roger won the Can Am championship with the “Turbo Panzer” Porsche 917/30. Having achieved pretty much everything in the US, including a NASCAR Winston Cup win at Riverside driving a Penske AMC Matador to become the last ‘road ringer’ to win a non oval race in that series back in 1973 Mark announced he would hang up his helmet at the end of the season.

Roger Penske made plans for a Formula One team in 1974 and sent Heinz Hofer to look at Graham McRae’s ‘low profile’ premises on the Creekmore Industrial Estate in Poole, Dorset UK as a possible base and concluded a deal for the premises. The Ford Cosworth DFV powered Penske PC1 was built to a design by Geoff Ferris and Mark Donohue was persuaded to come out of retirement to drive the car on it’s debut in the 1974 Canadian Grand Prix where he qualified 24th and finished 12th 2 laps down.

Penske Ford PC1, US Grand Prix, Watkins Glen

At the US Grand Prix, where Mark Donohue and Roger Penske fan, Brian Brown took today’s photograph of Mark in the PC1 at Watkins Glen the car started 14th on the grid, but retired after 27 laps with rear suspension problems. Brian recalls his first visit to a Grand Prix thus :-

“I was of course very excited to be seeing Mark race again, but being that it was my first live Formula One event, I was equally excited to be seeing Mario’s effort with Vel’s Parnelli Jones and the rest of the grid in person. We owned a Ferrari 365 GTB/4 Daytona and a 246 GT Dino at the time, so were very supportive of the Ferrari effort too.

My brother, friends and I spent a great deal of down time in the Kendall Garage watching the teams go about their business of working on the cars. One thing that was apparent was the absolutely professional presentation of the Penske team. Everything was spotless, just like their successful Indy Car counterpart that I’d observed in person since 1969 at Indianapolis. I was then, as now, a huge fan of Mark Donohue and Team Penske, but that aside, I always felt that they had too many positive resources not to be successful in Formula One.

I knew racing well enough to understand how tall the task Mark and the Penske team had ahead of them, but I also had the highest faith in their collective talents that I felt, given time, they would come right. I look back now and remember how I’d call in to our local ABC news tv affiliate to get the results of the races in 1975, always asking about the top six finishers along with Mark and Mario’s results.

Then came Austria and it was over for Mark and eventually Penske stopped the project – I was always appreciative that they carried on to get the victory with John Watson in Austria a year after Mark’s accident, something of a vindication for the mighty challenges that Team Penske faced in their Formula One foray. Watkins Glen 1974 was the last I ever saw Mark in person and despite the nearly 40 years that have passed, it seems like yesterday.”

Penske ended up building 3 chassis to the PC1 design chassis #001 seen here achieved a best 5th place finish, from 16th on the grid in the 1975 Swedish Grand Prix. Three races later Penske ditched the PC1 in favour of a March 751 which was raced until a new challenger until the new Penske PC3 was ready. As Brian alluded to above Mark Donohue was killed during practice for the 1975 Austrian Grand Prix after a tyre deflated pitching him off the track in to an accident which killed a marshal. Although Mark initially survived the incident he died the next day from a cerebral hemorrhage.

The debut of the Penske PC3 was delayed until the 1975 US Grand Prix where John Watson drove it in practice. Due to a misfire with the motor in the new car the team elected to wheel out today’s featured chassis one more time, John qualified 12th, finishing the race in 9th.

The following season Penske entered John in the PC3 and later PC4 models. With the latter the team won the 1976 Austrian Grand Prix, despite this success The Captain closed the Formula One program down at the end of 1976, deciding his future lay in the US racing seen where he would become the dominant force in Indy Car racing, with many of his winning cars being built in Poole, Dorset. Penske maintained facilities in Poole Dorset up until 2006. When the factory was closed one employee, Ivor, remained who had been part of the story going back to the Leda days, through the McRae years and into the Penske era.

In 2012 Brad Keslowski won his first NASCAR Championship driving a Penske entered Dodge a hitherto elusive goal on ‘The Captains’ to do list.

My thanks to Brian ‘ B² ‘ Brown for kindly agreeing to share his photograph; to kayemod, Nigel Beresford, Tim Murray, Tony Matthews, Dogearred and Doug Nye at The Nostalgia Forum for their help in piecing together the story behind Roger Penske’s presence in Poole, Dorset and a tenuous connection in the form of Lambert & Terry and their Leda Cars premises between the AAR Eagle and Penske Formula One efforts.

Thanks for joining me on this “Balena Close, Poole, Dorset” edition of “Gettin’ a li’l psycho on tyres”, I hope you will join me again tomorrow. Don’t forget to come back now !

PS Shortly before this blog was posted some confusion has come to light about which buildings in Poole Penske and McRae occupied and when, local resident kayemod and Nigel Beresford who worked for Penske have confirmed that Penske took over the Balena premises from McRae, while artist Tony Matthews is sure he visited a second facility a couple of miles away on Factory Road to do cutaway drawings for McRae and Penske is not so sure the Balena Close address is correct. If any further developments come forth I shall post them below, and if you know the answer to the riddle please do not hesitate to chime in.

PPS Nigel Beresford has kindly confirmed with another former Penske employee Nick Goozée that the Balena Close facility is the only one Penske purchased from Graham McRae. My thanks to Nigel and Nick for settling the matter so promptly.

Balena Close, Poole, Dorset

Kayemod Rob from the Nostalgia Forum has kindly sent me this photo showing “how that corner of Balena Close looks today, the small unit to the right is the original Penske UK base, formerly McRae Cars. The three parked cars more or less cover the width of the premises. The ‘Elegance’ unit to the left of Penske was once FKS Fibreglass, later Griffin Design. My ex-Specialised Mouldings chum stylist Jim Clark worked at FKS, and as well as Penske’s stuff, they also did almost everything for the Gulf GT40s and Mirages among others, their unit extended leftwards to fill the corner of the block. Penske later rented an identical unit to the right of the pic, which doubled their floor area, after some of the dividing wall was removed, they used to run their F1 operation out of that.”

Thanks Rob.

Shimmying Past Scrutineers – Ford Mark IV #J5

The Ford Mark IV was the culmination of Ford’s determination to crush Ferrari on it’s own turf, after Enzo had bailed out of selling his eponymous company to the men from Dearborn at the last minute in 1963.

Ford Mark IV, Goodwood Festival of Speed

What started out as an Eric Broadley designed Lola GT powered by a Ford Indy spec V8 in 1963 had been developed into the Ford GT40 with input from Ford’s designers led by Roy Lunn. The GT40 was the subject of two humiliating failures at Le Mans in ’64 and ’65 but then blossomed into the Shelby developed 7 litre / 427 cui Ford GT40 Mark II that swept to a 1,2,3 victory at Le Mans in 1966.

Ford Mark IV, Goodwood Festival of Speed

Unable to convince Ford that they needed to build the GT40 with an aluminium frame to save weight Eric Broadley left the GT40 project in 1965 and returned to Lola while Ford and Shelby got to grips with producing a steel framed car that was both powerful enough and strong enough to last 24 hours at a race winning pace.

Ford Mark IV, Goodwood Festival of Speed

Ford soon realised that Eric was right about the extra weight carried by the steel framed cars and before the steel framed GT40 Mk II’s romped to victory, in ’66, they set about building an aluminium framed version of the GT40 with the same drive train and suspension components known as the J-Car featuring an innovative aluminium honeycomb monocoque manufactured by Brunswick Aerospace.

Ford Mark IV, Goodwood Festival of Speed

The J-Car was subject to much experimentation with body shapes and even crash testing after Ken Miles had been killed in a freak accident testing a J-Car. By 1967 Ford had four of the new Mark IV’s ready for the Le Mans 24 hours powered by 7 litre / 427 cui motors.

Ford Mark IV, Goodwood Festival of Speed

According to Dan Gurney the Mark IV’s were fitted with suspension shims to ensure they passed the scrutineers / tech inspectors minimum ride height test held in the middle of town, these shims then “fell off” on the way back to the race track to ensure the Fords had some aerodynamic stability when they hit 200 plus mph on the 4 mile Mulsanne straight.

Ford Mark IV, Goodwood Festival of Speed

Dan Gurney set the winning car up then he and Le Mans rookie AJ Foyt then set about winning the race, during the middle of the night Dan over slept forcing AJ to do a double stint behind the wheel but other than that their car had no problems on it’s way to a four lap victory over the Ferrari P4 of Ludovico Scarfiotti and Mike Parkes. The sister Shelby run Goodyear shod car of Bruce McLaren and Mark Donohue came forth behind another Ferrari P4 after loosing time with a tale piece that was ripped off.

Ford Mark IV, Goodwood Festival of Speed

On the podium Dan Gurney started a tradition of shaking up the winners bottle and spraying champagne all over the gathered revelers which has been repeated by race winners around the world countless times since. The day after the race the Mark IV’s were effectively banned from racing in 1968 and Ford withdrew from any further factory participation on the spot.

Ferrari ended up winning the World Sports Car Championship in 1967 but it hardly mattered since everyone remembers who won the signature event of the series the Le Mans 24 hour race.

The car driven by Gurney was different from the three other Mark IV’s in the race because to accommodate Dan’s 6’3″ frame a blister was built into the roof and the seat was lowered. After the race all four Mark IV’s, the two Firestone shod cars run by Holman Moody had crashed out, returned to the States were overhauled and all four painted to look like the winner complete with a blister in the roof.

The winning car chassis #J5 has been kept at the Ford Museum however I am led to believe this is the same car that appeared at Goodwood last year, but I maintain an open mind since Ford sold chassis #J6 to New York collector James Glickenhaus believing they had sold him the 1967 winning car until closer inspection revealed otherwise.
