La Machine – #17 Vollstedt – Offenhauser 77

As I have blogged elsewhere in 1978 the USAC Championship came to England and I was lucky enough to see the one of the two championship races at Silverstone and meet some of those involved at a meet and greet at Jubilee Gardens on the banks of the Thames in Central London.

Vollstedt Offy 77, Jubilee Gardens

One of the enduring memories of those two events was seeing the striking lines of Rolla Vollstedts #17 La Machine – Vollstedt – Offenhauser 77, to my mind one of the most visually arresting open wheelers ever built, one that has a place of special veneration reserved at the top table in Art Tidesco’s Automotive Temple of Speed.

Vollstedt Offy 77, Silverstone

1960 US Olympic Team Skiing alternate Dick Simon was the driver of the immaculately turned out Vollstedt. Simon’s best finish in 1978 was 4th at Phoenix he also scored three further top tens finishing the season 18th in the Champ Car Series standings.

Vollstedt Offy 77, Jubilee Gardens

The master mind behind the car was Rolla Vollstedt, a man with more stories to tell than I’ll ever have hot dinners. Rolla has been devoting his life to racing since 1937 when he took part in unsanctioned Oregon street races with a Buick Coupé in 1937.

Working with modest budgets among Rolla’s many achievements since starting his team in 1947 are building the first rear engined Offenhauser powered Indycar complete with rear wing to improve traction and counting the legendary Jim Clark, in 1967, along with Janet Guthrie, the first woman to compete in the Indy 500 among the drivers of his Championship cars. Rolla was also the last owner to attempt to qualify an Offenhauser powered for the Indy 500 in 1983.

I would like take this opportunity to wish Rolla a happy 93rd Birthday Day and thank him for building one of the most alluring automobiles it has ever been my privilege to see.

Thanks for joining me on Rolla Vollstedt’s Birthday edition of ‘Gettin’ a lil psycho on tyres’, I hope you’ll join me again tomorrow for Ferrari Friday. Don’t forget to come back now !

Three Time Winner – McLaren Offy M16

09 07 03 022sc

The McLaren M16 was designed by Gordon Coppuck in 1970 and took essential design queues from the Lotus 72, that was dominant in Formula One, including the chisel nose and side mounted radiators.

On it’s Indy debut in 1971 M16’s of Revson, Donohue and Hulme qualified 1st, 2nd and 4th for the 500, the race was won by repeat winner Al Unser with Peter Revson coming home a career best 2nd. Mark Donohue driving for the private Penske team said of the M16 that it “…obsoleted every other car on track…” and proved it with a win in 1972.

In 1973 Johnny Rutherford, seen driving the M16C/5 here at Goodwood Festival of Speed, took pole position again in his works M16 though the Eagles of Johncock and Vukovich Jr took first and second in the race that was called early due to rain. The following season driving the same car Rutherford started 25th on the grid and went on to win the first of his three Indy 500’s.

Lloyd Ruby drove the #7 Allied Polymer Group M16E/2 qualifying 6th and finishing 32nd in 1975 and in 1976 Rutherford dominated the Indy 500 with a victory from pole in this ex Ruby chassis. Cliff Hucul raced this same car at Indy from ’77 – ’79 qualifying a best 18th in ’79 and finishing a best 22nd in ’77.

Bob Harkey seen in the #33 Dayton Walther M16C/2 here in 1975 qualified 23rd for the Indy 500 and after 18 laps handed the car over to Salt Walther who’s own M16 had experienced turbo failure after 2 laps. Salt was flagged in 10th at the conclusion of the rain affected race. In 1976 David Hobbs nade his fourth and final Indy start in this car starting 31st and finishing 29th.

In 1978 Jerry Karl modified M16C/2 fitting a Chevrolet stock block motor, Karl made three starts in ’78, ’80 and ’81 recording best start positions of 28th in ’78 and ’80 and a best finish of 14th in ’78. This car still fitted with a Chevy stock block but now with orange #15 bodywork as used by Peter Revson resides in the Matthew Collection.

My thanks to Steve Arnaudin for scanning his Dad’s photographs and to everyone who contributed to the M16 thread on The Nostalgia Forum for providing the chassis details.

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.

Trading Places – 1960 Watson Roadsters

Thanks to Ed Arnadin‘s photos today we will be continuing our 100th anniversary of the first running of the Indianapolis 500 by having a behind the scenes look at Indianapolis in 1960.

Watson, Indy 1960

Our story begins with an invitation from a mutual friend of Ed Arnaudin and the Indy car owner Jim Robbins to visit the garage of the #97 Jim Robbins Special, where a Watson Roadster powered by an upright 4178 cc / 255 cui twin overhead cam Offenhauser is being prepared.

AJ Watson shares the record for building the most cars that won the ‘Indy 500’s’, seven, with Roger S Penske. Watson built his first car ‘City of Glendale’ in 1950, Dick Rathmann qualified 18th on the grid driving the ‘City of Glendale and retired from the race with a stalled motor after 25 laps. After working on aircraft assembly lines for Lockheed Watson was hired as Chief Mechanic by John Zink in 1954.

Watson modified Zinks Kurtis KK500C roadster and Bob Swiekert duly won the 1955 Indy 500 with it, in 1956 AJ built the first of 23 Watson Roadsters for John Zink, these iconic vehicles were to win a further six Indy 500’s in 9 years.

The Watson chassis was narrower than the Kurtis, featured extensive use of 4130 chromoly tubing in place of the steel used by Kurtis, innovative use of magnesium in the drive line and body panels saved further weight. The Offenhauser engine was mounted upright on the left side of the chassis to increase weight bias on the corners of the car closest to the inside of the track rather than tilting the engine at 36 degrees as Kurtis had done and later Eperly / Salih would do with engines 18 degrees off horizontal.

With a 220 lb weight saving the 1,640 lb Watson Roadster design remained fundamentally unchanged from 1956 until 1963, AJ Foyt drove a Watson into Victory Lane at Indianapolis for the last time in 1964.

The car, seen being worked on above was one of three entered in the race owned by Safety Belt manufacturer Jim Robbin’s, the #97 was driven by the man who first put a Watson on the grid of the Indy 500 in ’53, Dick Rathmann. In 1960 Dick qualified for fourth spot on the grid and retired from the race in 31st place after 42 laps with defective brakes.

Dick Rathmann had a varied career spanning 1949 – 1964 encompassing the AAA Championship, NASCAR (13 wins, all in Hudsons, from 128 starts) and latterly the USAC Championship. He started from the Indy pole in 1958 but was collected in an accident on the opening lap by fellow front row starter Ed Elisan, the ensuing 15 car pile up cost Pat O’Conner his life.

As a result of that fatal accident Dick Rathmann became the first man to start from pole not to complete a lap of the race, a stat that has since been emulated by Roberto Guerrero and Scott Sharp. Rathmann’s best Indy 500 finish was 4th in 1956.

Now this story enters the racing twighlight zone, ever since races were organised teams and drivers have made it there business to pull the wool over organisers eye’s. ‘Dick’ Rathmann was actually born James. James had a brother, younger by four years, called Richard and when underage Richard wanted to go racing in 1946 James and Richard simply swapped names, James became ‘Dick’ and Richard became ‘Jim’ a change that ended up sticking for life.

Indy 500, 1960

In 1960 Jim Rathmann was the driver of the #4 Ken Paul Special a Watson Offenhauser Roadster MK2, Jim qualified 2nd and can be seen in the blue car in the middle of the front row as the cars cross the 100 yards of bricks at the start of the 1960 Indy 500 above, his brother ‘Dick’ in the #97 is on the inside of the second row.

Rathman and Sachs, Indy 500, 1960

Jim seen here battling with Eddie Sachs went on to win the 1960 Indy 500, a race memorable because the lead changed a record 29 times. Last year (2010) Jim became the sixth Indy 500 winner to celebrate their 50th Anniversary of the Indy 500 win, Ray Harroun, Jules Goux, Rene Thomas, Peter DePaolo and Louis Meyer were the others.

Three time Indy winner Johnny Rutherford presented Jim with a trophy to commemorate the 50th anniversary of his win, Rutherford who was present at Indy as a spectator for the first time in 1960 remembered the race thus ” We had seats in the North grandstands of the infield on the backstretch. The duel between Jim and Rodger [Ward winner of the 1959 Indy 500] was one for the record books. Little did we know that some 50 years later [the 29 lead changes] would still be an Indy 500 record.”

Jim said of the 1960 Indy 500 “That was a great duel with Rodger. Ward was one of the toughest drivers out there and beating him meant a lot to me, and winning the Indy 500 changed my entire life. Winning the ‘500’ was and still is the all-time highlight of my racing career. To win that day, in that race against Ward means so much to me.”

Slightly off topic after retirement Jim became a Cadillac dealer in Melbourne, Florida and is credited with convincing GM president Ed Cole that GM should set up a deal to supply his friends the astronauts on the NASA space programmes with a pair of new cars each year.

Shoestring Winner – Epperly Belond Exhaust Special

Today’s photograph by Ed Arnaudin of the two time winning Belond Exhaust Special, seen here with Sam Hanks at the wheel, was taken in 1982.

Indy82011s

The success of the Belond Exhaust Special is a testament to three men who persevered, (Gordon) Howard Gilbert a 1949 Indy 500 winning mechanic with the Blue Crown Spark Plug Special team, Howard’s neighbour George Salih a foreman at Meyer & Drake which produced the prevalent 16 valve twin cam 4 cylinder Offenhauser ‘Offy’ engine and Sam Hanks a driver who after 12 races at the Brickyard had yet to win his first Indy 500.

Salih and Gilbert came up with the brilliant idea of replicating the best features of the 1952 Pole Winning Cummins Diesel Special but without the bulk of the 3,100 lbs diesel powered vehicle.

In 1952 Frank Curtis built two cars with the engines inclined the Cummins Diesel with its engine inclined 5 degrees off horizontal and The Fuel Injector Special belonging to Howard Keck with the engine inclined 36 degrees.

Gilbert and Salih decided to build their car with a compromise between the two ’52 Kurtis Kraft chassis with the engine inclined at 18 degrees off horizontal which decreased the frontal area and lowered the centre of gravity of their car without inducing the lubrication problems that would accrue by inclining the engine at 5 degrees from horizontal, the Cummins diesel was not capable of the high crankshaft revolutions of the gas powered Offenhauser and so was easier to keep lubricated at 5 degrees from horizontal.

In order to build their engine Salih obtained cosmetically flawed Offenhauser parts on credit, and both took out mortgages on their homes to build the chassis, an operation that took place during nights and weekends between day jobs.

Having completed their chassis Quin Epperly built the bodywork in exchange for part ownership, the car is officially known as an Epperly. Exhaust manufacturer Belond got the naming rights for $2500 in sponsorship.

A contingency fund was secured for the #9 Belond Exhaust Special by equipping it with British Blue Lodge Spark Plugs as against the Champion items used by everyone else taking part in the 1957 Indy 500.

Salih got 1953 AAA Champ and 12 time Indy 500 veteran, Sam Hanks, with whom he had worked in 1956, to drive what at the time was the lowest and smallest vehicle of it’s type to a debut victory, at a record speed of 135 mph, whereupon Hanks immediately announced his retirement from racing.

The Belond Special became the first car to head to victory lane twice with different drivers in 1958 when 3 time champ Jimmy Bryan repeated Hanks achievement. In 1959 Bryan retired the Belond Special with a broken engine after just one lap.

Gilbert and Salih continued building cars until 1967, Jimmy Bryan died soon after the linked photo was taken as a result of injuries sustained in an accident at Langhorne in 1960.

Howard Gilbert built further vehicles until 1970 scoring a shock win with George Follmer at the wheel of a stock block Chevy powered Cheetah at Phoenix, in the Jimmy Bryan 150.

From 1970 to 1990 Howard built engines for AJ Foyt which took 25 champ car wins including the 1977 Indy 500, fourth victories at Indy for Gilbert and Foyt, along with USAC championships in 1975 and 1979.

With thanks to Steve Arnaudin for scanning his Dad’s photos to and Kevin Triplett for additional information.

Winning in the rain – Wynn’s Friction Proofing Special

To accommodate Ferrari Friday I got a little out of sequence with my posts celebrating the Centenary of the first running of the Indianapolis 500, today we are looking at the 1950 Wynn’s Friction Proofing Special, thanks to a photograph taken by Ed Arnaudin in 1980.

Indy80 016s

Frank Kurtis the designer of extremely successful midget, 1/4 midget, sports and sprint cars also designed and built some 120 Champ cars for the Indianapolis 500, marketed and manufactured under the Kurtis Kraft name.

His creations took five victories between 1950 to 1955, so it is no stretch to say Kurtis dominated at Indianapolis in the first half of the 1950’s.

The first Indy 500 winner Kurtis Kraft built was the Wynn’s Friction Proofing Special seen in today’s photograph, the car was powered with a ubiquitous, for the period, 4,424 cui / 270 cui 4 cylinder twin overhead cam Offenhauser motor.

Driving the Wynn’s Friction Special in 1950 was Johnnie Parsons who won the rain shortened ‘Indy 500’ on just his second attempt. Due to an engravers error, Johnnie’s name was spelt incorrectly on the Borg Warner trophy, an error that was not corrected until the trophy was refurbished in 1991. Until then I am sure Johnnie’s son Johnny probably enjoyed having his name on the trophy even though it was next to his Dad’s face.

Johnnie took part in 10 Indy 500’s from 1949 – 1958, his best finishes beside the win were 2nd in 1949 and 4th in 1956. Parsons also won the Turkey Night Grand Prix for midgets in 1955, a race won more recently by NASCAR drivers Jason Lefler in 1999 and Tony Stewart in 2000.

My thanks to Steve Arnaudin for scanning his Dads photograph.

29 05 11 Errata, thanks to evidence provided by Tim Murray it turns out that as of 2005 the Johnny Parsons spelling error had not been corrected. Apologies for any confusion caused.
