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.

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.

Wheelbase Balance – McLaren Chevrolet M8F #10-72

There were three race winners in the 1971 Can Am Challenge Jackie Stewart won two races in his L&M Lola T260 while the rest all fell to Denny Hulme who won three races and eventual champion Peter Revson who won the remaining five in the fifth and final year of domination by the Traffic Yellow McLaren M8F cars.

The McLaren M8F was similar to the M8D raced in 1970 but had been upgraded by Gordon Coppuck with a 3″ longer wheel base, wider track, inboard rear brakes, sturdier gearbox to improve the handling and balance of the cars which had a choice of either 740hp 8.1 litre / 494 cui or just under 800 hp 8.4 litre / 512 cui Gary Knutson tuned alloy Chevrolet V8’s.

Agg, McLaren Chevrolet M8F, Brands Hatch

For 1972 the works McLaren team moved onto the M20 and sold on it’s M8F’s to the Young American Racing Team, one of which was driven to victory at Donnybrooke by rising French star François Cevert, while Trojan built up a number of M8F spec cars known as M8FP’s for customers to run.

The most successful M8FP customer in the 1972 Can Am Challenge was German Hans Weidmer who finished 8th from 21st on the grid at Edmonton driving chassis #07-72.

Agg, McLaren Chevrolet M8F, Brands Hatch

Helmut Kelleners sold his March 707/717 and raced a Trojan built M8FP #02-72 in various events through 1972 winning the Martini International at Mainz Finthen. In December ’72 Georg Loos won the Copa Brasil at Interlagos driving chassis #03-72.

By 1975 Peter Hoffmann had acquired #07-72 for racing in Europe and in 1976 returned the car to victory lane at Kassel Calden, Mainz Finthen and Ulm. Peter drove the car to three more victories at the Nurburgring in 1979 and 1981 and Hockenheim in 1980.

Today’s featured car #10-72 is seen with Charlie Agg at the wheel during practice for a classic race at Brands Hatch, #10-72 was never raced in period. Charlie Agg is the son of Peter Agg who revived the fortunes of Trojan and then Elva in the 1960’s.

More Fuel – McLaren Ford M14A #M14/2

Going into 1970 things were looking up as McLaren Cars entered their seventh year. The team had won three consecutive Can Am Championships, 2 for Bruce McLaren and one for Denny Hulme, the inaugural European Formula F5000 championship with Peter Gethin and four championship Formula One races one for Bruce McLaren and three, including the last race of 1969, for Denny Hulme.

In addition to these racing programs for 1970 McLaren were to embark on an Indy program with the new turbocharged McLaren Offy M15 and were contracted to run an Alfa Romeo V8 powered car alongside their new Ford powered M14A Formula One car.

McLaren Ford M14A, Goodwood Revival

The new M14A was an improvement of the 1969 McLaren M7C, itself based on a Formula F5000 M10A chassis with McLaren M7A Grand Prix winning suspension.

The main feature of the new car was the narrower internal dimensions of the monocoque which were necessary to accommodate larger fuel tanks required by the ever more powerful and thirsty Ford Cosworth DFV V8’s.

McLaren Ford M14A, McLaren Manchester, Knutsford

The McLaren M14A was used in all but one race in the 1970 Formula One championship season. It’s best result was on it’s debut in South Africa where Denny Hulme finished second, driving I believe today’s featured car. Bruce McLaren matched that in Spain where he also finished second. After the Monaco Grand Prix where Denny finished forth disaster struck as first Denny was badly burned after his car caught fire in testing at Indianapolis and then a couple of weeks later Bruce was killed while testing the M8D Can Am car at Goodwood.

The team consequently missed the Belgian GP and reappeared at the Dutch Grand Prix with Dan Gurney driving the lead car #M14/1 and 1969 European Formula 5000 champion Peter Gethin making his Formula One championship debut driving today’s featured chassis, both cars retired. Denny Hulme still suffering from burned hands was back in time for the French Grand Prix alongside Dan Gurney and the pair came in 4th and 6th respectively.

#M14/2 is seen at the McLaren Manchester show room in Knutsford above.

Dan Gurney retired from Formula One after retiring from the British Grand Prix where Hulme finished a remarkable 3rd. Peter Gethin was back in the team for the German Grand Prix where Denny again finished 3rd. Denny retired from the Austrian GP but at Monza for the Italian Grand Prix he came home 4th. Peter Gethin scored his first World Championship point at the Canadian Grand Prix where he finished 6th and Denny rounded out a painful year with a third in the Mexican Grand Prix finishing 4th in the Formula One Championship points table.

Incredibly despite his injuries Denny had also won 6 of the 10 Can Am Championship rounds enough to win the 1970 Chamionship his second Can Am Crown and McLaren Cars 4th consecutive championship aided by a further win from Peter Gethin who also won a second consecutive European Formula 5000 title driving a McLaren. The US, New Zealand and South African Formula 5000 thousand championships were won by John Cannon, Graham McRae and Bob Olthof respectively all also driving McLarens.

McLaren Ford M14A, Goodwood Festival Of Speed

For 1971 #M14/2 was driven by Peter Gethin to two second place finishes in non championship races at Oulton Park and Brands Hatch, the best championship result Peter had from 3 championship start in the car was 8th in the 1971 Spanish Grand Prix.

Jackie Oliver joined McLaren for the British Grand Prix where he qualified #M14/2 22nd but a bungled flag drop saw Jackie crash into Graham Hill at the start causing instant retirement for both and a £50 fine for Jackie. The cars final works appearance was at the 1971 Italian Grand Prix where Jackie qualified 13th and finished 7th in a close fought race won by Peter Gethin now driving a BRM.

#M14/2 next appeared with a Formula 5000 Chevy stock block V8 motor in the hands of Tony Dean who’s best result was a 10th place finish in his first start in the car at Mondello Park. On his seventh and final attempt, which included retirements from races at Elkhart Lake and Brainerd, to race the car Tony failed to qualify for the non championship 1972 John Player Challenge Trophy at Brands Hatch.

In 1973 at the same venue Willie Wood failed to qualify #M14/2 for the Formula F5000 race or non championship Race of Champions and was not classified in a further appearance at Oulton Park. Allan Kayes then bought #M14/2 was also unclassified at Brands Hatch, finished 11th at Oulton Park and then retired, failed to qualify or failed to start in 12 further races most of which were rounds of the 1974 European Formula 5000 championship.

Third Time Lucky – McLaren Ford M7A

After the disappointments of the Ford Indy derived V8 and Serenissima V8 used in the 1966 McLaren M2B, the interim BRM V8 Formula 2 based McLaren M4B and BRM V12 powered M5A of 1967 Bruce Mclaren bought 5 Ford Cosworth DFV motors for the 1968 season which were used as in the integral structure of the McLaren M7A designed by Robin Herd, Gordon Coppuck and Bruce himself.

McLaren M7A, Donington Park Museum

The M7A’s and 3 derivatives, M7B, M7C, and Alfa Romeo powered M7D were entered by the works team from 1968 to 1970. For 1968 the works Formula One McLaren’s were sponsored  by Shell while the McLaren Can Am Cars were sponsored by Gulf.

McLaren M7A, Donington Park Museum

Reigning World Champion Denny Hulme left Brabham to join McLaren in 1968 and on the M7A’s debut at the non Championship Race of Champions at Brands Hatch Bruce came first and team mate Denny Third. The M7A’s came in first and second at the non Championship International Trophy at Silverstone with Denny Hulme came edging the team founder.

McLaren M7A, Donington Park Museum

On their third championship appearance, after Spain and Monaco, Bruce McLaren became the second man to win a Grand Prix bearing his own name crossing the line first to win the 1968 Belgian Grand Prix. It would prove to be his forth and final Grand Prix victory.

McLaren M7A, Donington Park Museum

Denny Hulme won the Italian and Canadian Grand Prix towards the end of the season and finished third in the World Drivers Championship behind Graham Hill and Jackie Stewart, Bruce finished fifth in points standings. McLaren finished second in the constructors Championship behind Lotus but ahead of the Ken Tyrrell entered Matra driven by Jackie Stewart all three constructors used Ford Cosworth DFV motors.

McLaren M7A, Donington Park Museum

In 1969 Bruce only drove an M7A in South Africa where he finished fifth before focusing on the M7C, which will be the subject of a future blog, which featured a more substantial monocoque. Denny meanwhile continued driving the M7A throughout the 1969 season winning the season finale in Mexico. Denny finished the season 6th in points with Bruce 3rd, the Mclaren team finished 4th and last of the Ford Cosworth DFV powered teams in the constructors championship.

The M7B fitted with outrigged panier fuel tanks made only one works championship appearance at the 1969 South African Grand Prix where Bruce Mclaren finished 5th. He later sold the car to Colin Crabbe who’s Antique Automobiles team entered it in four races for Vic Elford who finished a best fifth in the 1969 Dutch Grand Prix.

In 1970 McLaren adapted an M7 to take a non stressed Alfa Romeo V8 which became known as the M7D the car recorded three DNQ’s, did not qualify, a not classified finish in France and a DNS, did not start, in the 1970 British Grand Prix. After the first four events Nanni Galli took over the M7D from Andrea de Adamich, recording the cars third DNQ at the Italian Grand Prix.

Privately entered M7A were driven in three races by Dan Gurney for All American Racers in 1968, best finish forth in the US Grand Prix, and Basil van Rooyen for Team Lawson in the 1969 South African Grand Prix where he retired with brake problems after completing 12 laps.

06/07/13 Errata as Tim has pointed out below Bruce finished the 1960 season second in the World Drivers Championship and so his 3rd place in points in 1969 did not equal his career best as originally stated. Apologies for any confusion.

The Kiwi Bear Corrections – McLaren Offy M15

Firstly a big thanks to racer Jerry Entin who kindly corrected a blog I posted a couple of years ago about Denis Hulme’s participation in the 1970 Indy 500 and has kindly sent some additional photo’s from the IMS Archive to complete the story.

For 1970 Bruce McLaren had Gordon Coppock design the first McLaren Indy 500 challenger, above the #73 McLaren Offy M15 is seen in the Indy pit lane with Denny at the wheel, Tyler Alexander crouched beside him and Teddy Mayer with clip board on the pit wall. Jerry tells me the little guy in the back ground is Chickie Hirashima a well known crew chief and Offy engine builder.

The turbocharged Offenhauser’s that McLaren used were prepared by George Bolthoff (R) with help from the legendary Herb “Herbie Horsepower” Porter (L) of Speedway Engines.

his team mate in the #75 McLaren Offy M15 was to have been fellow New Zealander Chris Amon with whom team owner Bruce McLaren had won the 1966 Le Mans 24 Hours driving a Ford GT40.

Team owner Bruce McLaren, seen above squatting next to Denny, had tested the #79 M15 making a big impression driving in convoy with his #73 and #75 entries on the opening day of practice for the 1970 Indy 500 and Denny was to shake down the #79 back up car to cover all eventualities.

However the #79 developed a methanol fuel leak,

which caught fire, the only evidence of the fire in the photo above is the clearly visible heat haze above the far front wheel as Denny prepares to jump and roll away from his car which was still traveling at 70 mph.

Denny received severe burns to his hands which forced him to miss the Indy 500 and the next two Grand Prix however within a month he was back behind of the wheel of his McLaren Chevrolet M8D Can Am car winning the series with six race victories, a string of three third place finishes also helped Denny secure 4th place in the world drivers championship all while his hands were still healing.

Teddy Mayer engaged Peter Revson to replace Denny in the #73 for the Indy 500, Peter qualified 16th but retired and was classified 22nd.

McLaren Offy M15, Donington Park Museum

On seeing the extent of his countryman Denny’s injuries Chris Amon was not impressed with the Indy safety facilities and withdrew from the race.

Chris’s place in the #75 was taken by Carl Williams who qualified 19th and brought the car home 8th to record McLaren’s first finish in the Indy 500. The teams next design the M16 would become the class of the field in early 1970’s taking wins with Mark Donohue driving in 1972 and Johnny Rutherford in 1974 and 1976.

McLaren Offy M15, Donington Park Museum

However team owner Bruce McLaren would not see any of these success he was killed a couple of days after the 1970 Indy 500 testing a McLaren Chevrolet M8D Can Am car at Goodwood. Team manager Teddy Mayer took over the running of the Bruce’s legacy which is now the second oldest team in Grand Prix racing behind Ferrari.

My thanks to Jerry Entin, IMS Archive, Ed and Steve Arnaudin who made today’s blog possible and apologies for any confusion caused by getting the car Denny was driving when he got injured wrong in the original post.

Caution Wide Vehicle – McLaren M23 M23/6

McLaren M23, Donington

The Ford Cosworth DFV powered McLaren M23 was designed by Gordon Cuppock, based on the lessons learned from the successful McLaren M16 Indy car. The M23 driven by Denny Hulme burst onto the Grand Prix scene in 1973 with a pole position on its debut in South Africa. Denny scored the first win for the model in Sweden and Peter Revson followed that with wins in Great Britain and Canada in 1973.

For 1974 Denny who won his last race in an M23 in the season opening Argentinian GP was joined in the McLaren team by 1972 World Champion Emerson Fittipaldi who won in Brazil, Belgium, and Canada on his way to becoming the 1974 World Champion. McLaren also won the World Constructors title in 1974.

Jochen Mass joined Emerson in the McLaren team in 1975 winning the shortened Spanish GP while Emerson won in Argentina and Great Britain to finish 2nd in the World Drivers Championship.

1976 would prove to be the chassis most successful year in terms of wins with James Hunt, who replaced Emerson in the team crossing the line first in Spain, France, Great Britain, Germany, The Netherlands, Canada and the United States.

However 1976 was a year of high drama and comedy in Formula One first James was disqualified from the Spanish Grand Prix because his car was 1.8cm less than an inch too wide. In 1975 the McLaren had been used as a base model too set the dimensions for the 1976 Formula regulations.

McLaren successfully argued that when the tyres on the car were moving they were taller as a result of the centrifugal force taking up the slack on the side walls of the tyres and that this accounted for the discrepancy. The governing F.I.A. accepted this argument and the win was reinstated with a $3,000 fine, when the M23’s next appeared they had a slightly narrower rear track.

On the first corner, Paddock Bend, of the opening lap of the British Grand Prix James Hunt was the innocent victim in a crash with Ferrari’s Clay Reggazoni. The race was stopped and James who’s car was severely damaged took a short cut to get back to the pits when the race was stopped.

Come the restart the organisers initially refused to allow James to line up on the grid because the team had worked to repair his car while the mess was being cleared up. However people power intervened and fearing a riot from the partisan crowd the organisers relented, James took the win, he and the partisan crowd partied long and hard into the night and later the F.I.A. disqualified both Hunt and Clay Regazzoni from the event for having failed to complete the opening lap.

Up until this point reigning Champion Niki Lauda had dominated the 1976 Championship with four wins three seconds, the last of which became 1st after Hunt’s disqualification from the British GP and a third. The next race was the ill feted German Grand Prix in which Niki was eliminated in an accident that triggered an inferno from which he was lucky to escape with his life.

James won the German Grand Prix and the Dutch GP while Niki recuperated and 39 days after the inferno at the Nurburgring Niki and James met again at the Italian GP. At the end of practice for the Italian GP James and Mclaren team mate Jochen Mass and John Watson at Penske were found to be running with a fuel octane rating that was too high and had their Saturday times disallowed.

Since it had been raining during the first practice sessions on the Friday Hunt, Mass and Watson had effectively failed to qualify, however the 13 second plus off pace Otto Stuppacher was already on his way home to Austria when the announcement and the Marlboro sponsored Art Mezario withdrew as did Englishman Guy Edwards allowing Hunt, Mass and Watson to start.

Hunt crashed trying to make time and was applauded for doing so by the Tifosi and Lauda came home a remarkable 4th in his first race back.

James won both the Canadian and US Grand Prix while the brave Niki could only amass a further three championship points. Going into he last race of the season the Japanese GP Niki had a 3 point lead over James.

For the race James qualified 2nd behind Andretti with Niki just one place further back. I remember getting up at some unholy hour to watch this race live on TV in the UK and remember the disappointment when I saw the monsoon that unfolded on the track.

After much debate amongst the driver the race started and Niki who had lost his eyelids in the German inferno and yet to have them replaced through plastic surgery had little choice but to retire in the near zero visibility conditions. James took an early lead in the race but as the rain stopped and the track started to dry Hunt started losing ground dropping to 5th after a pit stop to replace a punctured tyre with just a few laps to go.

James charged back into the race managing to regain two positions which left him in third position when the flag came out for Mario Andretti to win by just over a lap from Patrick Depailler, with James Hunt, who had no idea what his position was in the race, right on his tail.

Hunt only learned that he had become champion after he got out of the car and stopped shouting at team manager Teddy Meyer for a less than perfect pit stop.

Hunt won the 1976 World Drivers title by just one point and Great Britain had it’s first World Champion since Jackie Stewart had won his last crown in 1973.

The McLaren M23 was pressed into service again in 1977 but its competitiveness was on the wane James winning a non championship race before committing fully to the M26 successor which had gone through a troublesome one year gestation period before coming on song.

The works M23 had a final swan song when it introduced Gilles Villeneuve to the world of Grand Prix racing in Great Britain and Bruno Jack’O’Malley in Italy towards the end of the 1977.

I have done my best to find out exactly which of the 13 M23 chassis this is, The Donington Museum blurb identified this car as McLaren M23/8 and said it was used to win the ’76 Spanish and US GP’s however M23/8 was destroyed in 1975. The car was then given a new tub with the chassis number M23/8-2 and the old tub was apparently eventually repaired to 1975 tall airbox spec and now resides in the United States.

M23/8-2 went on to become one of the stars of the 1976 season being used to win the controversial Spanish GP along with those in Canada and the US GP. M23/8-2 is said to belong to BCE the man responsible for running the the whole Formula Show since 1981.

It is said that the vehicle in my photograph appeared at the 60th Anniversary celebrations of the World Grand Prix Drivers Championship in Bahrain last year, it is also suggested that the M23 which appeared at Bahrain belongs to the brave octogenarian who started a modelling career with Hublot earlier this year however I have no firm evidence of the ownership of the vehicle in the photograph at the top of this post
at this time.

Most likely the vehicle above seen at the Donington Park Museum is M23/6 which seems to meet many of the criteria hinted at on various threads of The Nostalgia Forum and who’s whereabouts is listed as unknown by the respected Old Racing Car site.

M23/6 was used by Denny Hulme to win the Agentine Grand Prix in 1974 then in 1976 James Hunt drove it to win the French Grand Prix, cross the line first in Great Britain only to be disqualified .

At the next race the German Grand Prix I saw James win in this chassis which became one of a rare set of vehicles that crossed the line first in three consecutive races, though it was disqualified from one of them.

In 1977 Emilio de Villota drove M23/6 with little success in Grand Prix events, 2 starts three DNQ’s, but did win two rounds of a British series open to all single seat racing cars.

My thanks to Michael Ferner, Wouter Melissen, Steve Holter, Simon Hadfield, Slurp1955, at The Nostalgia Forum for their valuable contributions to todays blog.

The Kiwi Bear – McLaren Offy M15

This is the only photo to have so far surfaced by Ed Arnaudin at Indianapolis from 1970.

Indy70 001s

The car is a McLaren M15, based loosely on the Can Am dominating M8 chassis, Gordon Coppuck incorporated numerous parts from the M8 Can Am car into the design of the M15. The stressed aluminium monocoque chassis was held together with 3 steel bulkheads with the 4 cylinder Offy turbocharged engine bolted directly to the rear most and supported by two a frame running form the bulkhead to the bell housing.

The drivers of the cars were originally scheduled to be 1967 world champion Denny Hulme known as ‘The Bear’ in the #73 and Chris Amon in the #75, though team founder, Bruce McLaren also turned a few laps in the #79 spare car on the first day of practice running in a three car line astern McLaren train with fellow New Zealanders Denny and Chris. Bruce however never had any intention of taking the start.

The #73 of Denny caught fire during practice as a result of a fuel leak from a quick release breather cap that had not been properly secured. As Denny slowed the car down the intensity of the largely unseen methanol flames increased forcing him to jump from his car while it was still moving at an estimated 70 mph !

Denny was to miss the 500 due to the burns his hands received, meanwhile Chris Amon was not happy about the Indianapolis track set up, his speed was 3 mph slower than Bobby Unser who tested the #75 and the extent of the injuries received by Denny convinced him to withdraw from the race.

Teddy Meyer team manager drafted Carl Williams into the #75, he qualified 19th and finished 8th, while Peter Revson was drafted into the #73 qualifying 16th he retired from the race with a broken magneto classified 22nd.

2 days after the 1970 Indy 500 McLaren founder Bruce McLaren was killed testing the latest incarnation of the McLaren M8 Can Am car leaving Denny Hulme and Peter Revson to become the back bone of the McLaren team in Formula One, USAC and Can Am series until 1974.

Thank you for joining me on this Team Kiwi edition of ‘Gettin’ a lil psycho on tyres’ I hope you will join me again tomorrow. Don’t forget to come back now !

07 12 12 PS Jerry Entin has kindly informed me that the original plan was for Denny Hulme to drive the #73 but that he burned his hands shaking down the #79 McLaren. As a consequence Peter Revson was drafted in to drive the #73. I’ll be writing a full follow up blog with some interesting new photographs during the month of May.
