Americana – San Marino Motor Classic

San Marino Motor Classic, Horton/ McNabb

The first weekend of June saw Geoffrey Horton take his Jaguar XK140 FHC seen above to the San Marino Motor Classic.

Duesenberg Model A, San Marino Motor Classic, Horton/ McNabb

Among the US vehicles on display was this 1921 Duesenberg Straight Eight also known as the Model A first seen in 1920 but which did not go into production until 1921 by which time the motor had been fitted with an overhead camshaft.

Chrysler Imperial, San Marino Motor Classic, Horton/ McNabb

Powered by a 6.3 litre / 384 cui L head straight 8 the 1932 Chrysler Imperial was also marketed as the ‘Imperial 8’.

Ford Thunderbird, San Marino Motor Classic, Horton/ McNabb

In 1957 Ford built two competition Thunderbirds with supercharged Lincoln motors and Jaguar transmissions, of which I believe only one original, the #98, still exists. The car above appears to be a copy of the #99 which was dubbed the Battlebird by the media back in the day.

Chevrolet El Morocco, San Marino Motor Classic, Horton, McNabb

I had great fun trying to figure out if the vehicle above was either a 57′ Chevrolet or a Cadillac and it turns out to be a bit of both. Cadillac owner Ruben Allender came up with the idea of offering a $1,000 conversion to turn a Chevrolet into a Cadillac in 1956. It is thought 20 examples were built in the first year and possibly 16 more in 1957 when production ceased.

Watson Offy, San Marino Motor Classic, Horton/ McNabb

Finally for today I’ll leave you with this delicious vehicle labelled as a “1961 Indy Roadster”. The #41 was carried by Johnny Boyd’s Leader Card 500 Roadster sponsored Watson Offy in the 1961 Indy 500. Johnny qualified 20th and retired at just over half distance with a broken clutch.

My thanks to Geoffrey Horton and Paul McNabb for sharing today’s photographs more of which will appear on Tuesday and Friday next week.

Smaller, Lighter, RHD – Cunningham C6R

After experiencing less than outright success at Le Mans with the Cadillac Le Monstre Cunningham in 1950, Chrysler powered Cunningham C2R in 1951, similarly powered C4R in 1952 and C5R in 1953 Briggs Cunningham decided that three short comings of the previous designs had to be addressed.

His next new project the C6R, had to be smaller, lighter and right hand drive to optimise weight distribution on a circuit with predominantly right hand corners.

Cunningham C6R, Goodwood Festival of Speed

The C6R was also originally intended to be powered by a race bred 340 hp 4.5 litre / 274 cui Ferrari V12 motor of the type more commonly found in a Ferrari 375MM of the type he had run at Le Mans in 1954 for Phil Walters and John Fitch.

Cunningham C6R, Goodwood Festival of Speed

Responsibility of the design for the body of the C6R was handed over Herbert “Bud” Unger who had worked on the bodies of the Cunningham C4R and C5R Cunningham’s as a metal worker.

In correspondence with me, about the design, Mr Unger said; “The engineers wanted maximum air flow to the brakes front and rear…” These were 13 inch air cooled drum brakes, prone to fading when hot. “I made the front air intake as large as possible and also extra air intakes on both sides beside the main grille air intake.

Cunningham C6R, Goodwood Festival of Speed

Next, I tapered the side of the body in from the front fenders all the way back to the rear fenders and by large air scoops to get maximum ram air into both rear brakes.”

By the time the car appeared at Sebring in 1956 with it’s unpainted aluminium body, crafted by “a man form Europe that was an expert with the (English) wheel.

Cunningham C6R, Goodwood Festival of Speed

Briggs, for reasons unknown, compromised the original design criteria by fitting a modified 3 litre Indy 500 engine running on petrol instead of the usual alcohol brew.

Le Patron shared the driving at Sebring with John Gordon Bennett and they retired from the race on the 54th lap after the clutch disintegrated.

Cunningham C6R, Goodwood Festival of Speed

When the C6R appeared at Le Mans the body had some alterations including a single smaller front intake and a D-Type Jaguar like headrest and rear fin and the car ran over the weekend with the rear brake cooling intakes in open and blanked off configurations.

During the course of it’s second race Briggs and Sherwood Johnson found the C6R started loosing gears and it retired from 13th place after 18 hours after the engine had enough of pushing the car round in forth, top, gear only.

Cunningham C6R, Goodwood Festival of Speed

Briggs Cunningham raced the car one more time in 1955 at Road America where the Offy motor again expired for good.

The car did not run again until 1957 by which time a 3.8 litre 6 cylinder Jaguar six cylinder motor had been fitted.

Cunningham C6R, Goodwood Festival of Speed

Briggs raced the car on four occasions with a best known result of 9th at Lime Rock in June 1957.

The car was permanently retired to Briggs Cunningham’s collection thereafter which has since become part of the Collier Collection. It is seen here at recent Goodwood Festival of Speed meetings.

My thanks to Mr Unger, Cunningham Motorsport Historian Lawrence W. Berman, Paul Kierstein from the photo archive and Sondre Kvipt in Norway who facilitated my correspondence with Mr Unger. Thanks also to Herbert at The Nostalgia Forum who brought up the subject of the C6R’s blanked off rear air intakes.

D.A. Lubricant Special – Kurtis Offenhauser KK500H

For the 1958 Indianapolis 500 D.A.Lubricants sponsored an Offenhauser powered Kurtis KK500H that was to be driven by Johnny Thomson. Unlike previous Kurtis Indy cars this one did not lift it’s inside front wheel when going through the corners because it was the first Kurtis to be fitted with independent front suspension.

Kurtis Offenhauser 500H, Rolex Reunion, Laguna Seca

Johnny qualified the D.A.Lubricants Special 22nd and on the first lap got tangled up in the accident that killed Pat O’Conor damaging the suspension. Johnny continued for another 51 laps before the team called it a day, to be classified 23rd, with damaged steering. The race was won by Jim Bryan in the Salih Offy Belond Special.

Kurtis Offenhauser 500H, Rolex Reunion, Laguna Seca

In 1959 the D.A.Lubricants Special became the Smokey’s Reverse Torque Special driven by Duane Carter who qualified 12th and finished 7th to record the cars only Indy 500 finish in a race dominated by the Watson Offy’s driven by Roger Ward and Jim Rathman. Interestingly Smokey Yunnick had realised that by reversing the direction of the crankshaft and flywheel rotation the car should have had a better balance through the corners, hence the Smokey’s Reverse Torque name.

Kurtis Offenhauser 500H, Rolex Reunion, Laguna Seca

This cars final appearance in the 500 was in 1960 when Don Freeland drove the car now known as the Ross-Babcock Traveler qualifying 11th but being classified 22nd after withdrawing from the race with a magneto problem.

Ron Fournier restored the car to 1958 D.A.Lubricants configuration and to meet current vintage racing requirements in 2007.

My thanks to Geoffrey Horton for sharing his photo’s of the car seen at last years Rolex Reunion at Lagunna Seca.

Bardahl Special – Kurtis Offenhauser 500G

Ole Bardahl was the embodiment of the American dream aged 20 he arrived in Seattle from Norway in 1922 with $32 in his pocket and unable to speak a word of English, by 39 he had become a millionaire building contractor and went on to found the Bardahl Oil Company in Ballard Seattle.

Kurtis Offy 500G, Concours on the Avenue, Carmel by the Sea,

From 1950 to 1959 Bardahl sponsored Offenhauser powered Kurtis cars started in every Indy 500, two third places from Sam Hanks in 1952 and 1953 were the teams best results in this period. In 1956 a Bardahl showed up with the unique Ferrari powered Kurtis for Giuseppe Farina but the car proved too slow.

Kurtis Offy 500G, Concours on the Avenue, Carmel by the Sea,

For reasons that have not been determined during the research for this blog for 1957 Bardahl had Kurtis build two left hand drive Offenhauser powered 500G’s,all the other ’57 Kurtis Indy cars were right hand drive so far as I have been able to determine the #16 was driven by Al Keller and the #19 seen here by Jack Turner. Al Keller started the ’57 Indy 500 from 8th on the grid but crashed on lap 75 and was classified 27th, while Jack Turner started 19th and classified 11th last car on the lead lap.

Kurtis Offy 500G, Concours on the Avenue, Carmel by the Sea,

The ’57 Bardahl Kurtis Offy was by no means the only left hooker Indy car the manufacturer built, regular readers will remember that the Ross Page Special I looked at a couple of weeks ago was also a left hand drive machine, but the question remains as to why so few left hookers were built at all when almost all the other vehicles that participated in the Indy 500 at the time featured either a central driving position or a right side driving position ? If you have any references for an answer please do not hesitate to chime in below.

Kurtis Offy 500G, Concours on the Avenue, Carmel by the Sea,

For the 1958 Indy 500 Al Keller, perhaps best known as the first driver of a foreign car, Jaguar, to win a NASCAR sanctioned race, Linden, in 1954, took over the car seen in today’s photographs taken by Geoffrey Horton at the Concours on the Avenue in Carmel By The Sea a couple of years ago. Renumbered #52 Al qualified 21st completed all 200 laps and was classified 11th as had the cars previous driver Jack Turner in 1957.

Kurtis Offy 500G, Concours on the Avenue, Carmel by the Sea,

For 1959 Bardahl returned to the 500 with a conventional right hand drive Kurtis for Paul Russo who finished 9th. Through the 1960’s Bardahl entered Kurtis, Watson and Eagle cars with a best result of 3rd for Bobby Unser who drove a Bardahl entered Lola in the 1969 Indy 500 which appears to have concluded the teams participation in “The greatest spectacle in racing”.

My thanks to Geoffrey Horton for sharing his photographs which I have used in all of this months Indy 500 blogs, and to E.B. at The Nostalgia Forum for confirming today’s featured car was driven by Al Keller in the 1958 Indy 500.

Finally congratulations to Tony Kanaan for winning the 2013 edition of the Indy 500.

Blakely Oil Special – Schroeder Offenhauser

The Blakely Oil Special was designed and built by Gordon Schroeder for owner John McDaniel to enter in the 1951 Indianapolis 500.

Blakely Oil Special, Schroeder Offenhauser, Desert Classics, Concours d'Elegance

The #52 qualified 29th and finished 5th, having run has high as second, with rookie Bobby Ball at the wheel. Schroeder and Clint Brawner were on the crew led by Myron Stevens formerly of Miller who was also responsible for the fabrication of the chassis and the body work.

The Blakely Special was powered by a 4 cylinder 4.4 litre / 270 cui Offenhauser motor as were all the other cars in the 1951 Indy field apart from the two Novi powered Novi Purelube entered Kurtis chassis. Indy 500 historian Michael Ferner informs me that the The Blakely Oil Special failed to qualify for the 1952 500 after Bobby Ball crashed the car in practice.

Blakely Oil Special, Schroeder Offenhauser, Desert Classics, Concours d'Elegance

The Blakely Oil Specials next appearance in the Greatest Spectacle in Racing came in 1953 with Jimmy Bryan at the wheel. Jimmy qualified 31st and was classified as a runner in 14th place with 183 laps completed.

Blakely Oil Special, Schroeder Offenhauser, Desert Classics, Concours d'Elegance

In 1954 Andy Linden and Len Duncan driving for entrants Brown Motor Company and Brady qualified 23rd and 26th were classified 25th and 31st respectively driving Schroeder Offenhausers. Today’s featured car, seen in these photographs by Geoffrey Horton at last years Desert Classics Concours d’Elegance, did not qualify for the ’54 Indy 500 after Frank Mundy failed to complete his rookie orientation programme.

Blakely Oil Special, Schroeder Offenhauser, Desert Classics, Concours d'Elegance

John McDaniel nearly had a third DNQ at Indy in 1955 when Duke Nalon failed to make the cut, but rookie Keith Andrews saved the day by qualifying 28th and was classified 20th with 120 laps completed.

Michael Ferner has also told me that Tony Bettenhausen raced the car on dirt tracks in 1954 as did Bill Cheesebourg in 1956 when the car ran as the #23 McDaniels. Dick, father of 1979 Le Mans winners Bill and Don, Whittington bought the car in 1957 and ran it in dirt events and at Pikes Peak where the #36 came home with 21st fastest time slowest of the USAC entires to complete the course.

The car has been restored by Gary Schroeder, Dick Russell and Gary McCourt the original body by Wayne Ewing and Jerry Weeks, upholstery by Darel ‘Whitey’ Morgan and the motor by Phil Reilly & Co.

My thanks to Geoffrey Horton for sharing today’s photographs and to Michael Ferner at The Nostalgia Forum for sharing his wealth of knowledge.

Baby Hemi – Peugeot EX4/L3

May used to be the month where US open wheel racing was centered entirely on the story coming out of Indianapolis Motor Speedway, this month the iZod Indy Car Series breaks with tradition and will also be visiting Sao Paolo on May 6th, however GALPOT will be dedicating the next 5 Americana Thursday Posts to The Greatest Spectacle in Racing in years long gone by thanks to Geoffrey Horton who over the last two years has sent me numerous photo’s of Indy Cars from the Concours d’Elegance scene in California.

Peugeot EX4/L3, Palo Alto, 2011

This months five part potted history of the Indy 500 returns to 1914 when, as I found out two years ago, rookie René Thomas went to victory lane driving Delage Y, I forgot to mention René was accompanied by riding mechanic Robert Laly.

Today’s featured car the #14 Peugeot EX4/L3 was also entered in the 4th running of the Indy 500 for another rookie called Arthur Duray and US riding mechanician Henry Mattheys by Jacques Menier a member of the French Menier Chocolatier dynasty.

Peugeot EX4/L3, Palo Alto, 2011

In 1914 qualification for the 500 was slightly different procedure from what we are familiar with today, in the first two editions of the Indy 500 qualification was by date the entries were received providing a minimum speed had been achieved over a measure mile of the circuit in 1911 and a full flying lap in 1912. For 1913 and 14 with the arrival of foreign competitors a qualifying lap with a minimum speed was compulsory but the grid positions were determined by blind draw.

Peugeot EX/4 L3, Palo Alto, 2011

The Peugeot EX4/L3 that Jaques Menier bought featured an ‘L3’ 4 cylinder 3 litre / 183 cui version of the giant killing 7.6 litre / 463.78 L76 Motor that had successfully seen off the 15 litre / 915 cui FIAT’s in the 1912 French Grand Prix. Having proved with success the benefits of technical innovations that included twin gear driven overhead cams operating 4 valves per cylinder, which also featured the original hemi heads, designer Ernst Henry, aided by his driver engineers collectively known as “Les Charlatans”, proceeded to produce three further evolutions of of the motor with sizes of 5.6 litre / 341 cui, as used by Georges Boillot and riding mechanic Prévost to win their second consecutive French Grand Prix in 1913, 4.5 litre / 274 cui and the smallest of the family 3 litre / 183 cui L3 seen here.

For those interested in the minutiae of veteran era production methods there is a fascinating story regarding this particular motor whose block was found to have inconsistent longitudinal bore center lines on this thread on The Nostalgia Forum led by distinguished historian Doug Nye linked here.

Peugeot EX4/L3, Palo Alto, 2011

Alongside the winning two car Delage team Arthur Duray faced two EX3/L56 powered Peugeots of Georges Boillot with a riding mechaninc M. Brevot who ‘might’ have been Boillot’s regular mechanic Prévost with 1913 rookie winners Jules Goux partnered by Emil Begin. Boillot set the fastest time in practice of 99.860 mph but the draw by ballot for grid slots saw Jean Chassagne’s Sunbeam start from pole.

Peugeot EX4/L3, Palo Alto, 2011

Boillot was in a comfortable position to win the 1914 Indy 500 until repeated tyre failures led to a 14th place finish while Goux in the second large Peugeot finished 4th with Duray coming home second to the Delage of René Thomas.

Peugeot EX4/L3, Palo Alto, 2011

Arthur Duray who set three land speed records between 1903 and 1904 carried on racing until the 1930’s for manufacturers that included Hispano-Suiza, Ariès, B.N.C and Amilcar. At the 1921 French Grand Prix he was a spectator when running in second place Albert Guyot’s riding mechanic got hit on the head by a rock, Guyot pulled his Duesenberg up in the pits and it became apparent that his mechanic was too dazed to continue. On seeing this Arthur Duray is said to have vaulted the spectator fence pushed the mechanic aside cranked the Dusenbergs motor to life and jumped into the mechanics seat alongside Guyot who went on to record a sixth place finish.

The aforementioned Mr Nye has kindly informed me courtesy of Scott George at the Collier Collection, current owners of the vehicle, that “After its Indy days there is some suggestion it (today’s featured car) returned to France, plus a parallel suggestion that it stayed in the US. Sold to Harry Harkness who ran it a little in the north-eastern area, then sold to Kaufman, himself a New York Peugeot agent and team owner. The engine might have been “swapped out” of the chassis at some stage. Car then found at Benny Brandfon’s yard for old race cars and exotics in NY…”

Esteemed Indy historian Michael Ferner has expanded on what may have become of the car while in the care of Peugeot Dealer Alphonse Kaufman “The (#14) Meunier/Duray car, on the other hand, is a possible candidate for having served as the basis for the 1916 “Peusun Special”, apparently a Peugeot chassis with a Sunbeam engine and a Delage radiator!” If today’s featured EX4/L3 did form part of the Peusun Special this may tie up with Doug’s suggestion that the engine “might have been ‘swapped out’.”

Michael suggests James O’Keefes forthcoming book ‘Peugeot Racing In America (pre-WW II)’ should be a worthwhile read on the subject.

Harry Miller who had maintained and rebuilt a Peugeot L series motor copied the basic twin over head cam 4 valves per cylinder hemi head architecture for his own Miller motors that would come to dominate the Indy 500 in the 1920’s and 1930’s which would in turn be succeeded by “Offy” engines that former Miller employee Fred Offenhauser developed having bought the rights to the Miller motors when Miller went bust. The Offenhausers would remain competitive in ultimate turbocharged form at Indy until the mid 1970’s.

Of the 900 odd blogs I have posted to date this has without question proved one of the more challenging and I hope I have given an accurate summary of our knowledge of the car to date, my thanks to Doug Nye, Michael Ferner and Tim Murray, at The Nostalgia Forum and Scott George at the Collier Collection for their contributions to my understanding of the fascinating history of today’s featured Peugeot EX4/L3. Finally thanks to Geoffrey Horton without whose photographs their would have been no Peugeot EX4/L3 to blog about.

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

03/05/13 PS Geoffrey has informed me the electrical equipment attached to the front axle was a sensor connected to a computer seen in the cockpit by students of the Revs Programme at Stanford University to examine the Peugeot’s dynamics in motion.

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.

McLaren Offy M15, Donington Park Museum

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.
