Yellow Submarine – Chaparral 2K

In 1978 Colin Chapman revolutionised Formula One car design by introducing ‘ground effect’ to the upper echelons of open wheel racing with his Lotus 79.

By 1979 many Formula One teams were making copies and variations of the Lotus 79 using curved ‘venturi’ in the side pods between the wheels to gain traction grip by controlling the airflow between the lower surfaces of the car and surface of the road to create lowered air pressure underneath the car which ‘sucked’ the car to the road as it moved, the faster these vehicles were driven the more grip there was available.

When, in 1978, former Taurus Super Vee designer and McLaren draftsman John Barnard was employed to build an Indy Car for Jim Hall and the Chaparral team to replace their Lola T500 Champ Car, Barnard was the first to transfer the latest Formula One thinking to the Brickyard for the Indy 500.

Al Unser Snr qualified the Chaparral 2K 3rd on it’s debut at Indy and then ran away with the race until the transmission failed on lap 104.

The following year Al Unser Snr moved to the Longhorne team who were building a car based on a design by former Super Vee engine builder Patrick Head who’s Williams FW07 design started winning formula one races in 1979 and would win the Formula One World Constructors championships in 1980 and 81.

Johnny Rutherford pictured here alongside Mario Andretti, became the beneficiary of Al Unsers decision to move taking the Chaparral to Victory Lane at the Brickyard in 1980 and onto the PPG Indy Car World Series championship.

In all the Chaparral 2K won six races from 27 starts over three seasons. John Barnard moved back to Formula One with McLaren in 1980 where he introduced the first Carbon Fibre Composite (CFC) chassis into the series, almost all top open wheel series run vehicles using CFC chassis these days, and later in 1989 while working for Ferrari in 1989 he introduced the worlds first paddle shift electronic gear shift mechanism.

Between them Barnard and Patrick Head were the dominant designers during the 1980’s in Formula One interestingly they once worked together for a 46 year old London Taxi driver come racing driver Ronnie Grant on his Formula Super Vee team.

Triple 500 Crown – Lola T500

01 DSCN8489sc

During a run of success that included winning the US Formula 5000 championships from 1974 – ’76 with Brian Redman and Can Am 2 Championships with Patrick Tambay ’77 and ’80, Alan Jones ’78 and Jacky Ickx ’79, Jim Hall turned his attentions to the USAC champ car series in 1977. Hall and partner Carl Hass commisioned Lola to build the T500 a fresh design that was to be driven by Al Unser Snr in 1978.

02 09 07 03 028sc

The design was an instant success at Indianapolis Al qualified 2nd and led 121 laps to go to Victory Lane for the third time. Despite Al bending a front wing in the pit lane 20 laps from home pole sitter Tom Sneva in a Penske ran out of laps to catch the Lola which finished just 8 seconds ahead of Tom.

03 Image349sc

The ’78 Indy 500 was the first of ten that was won by a car powered by a turbocharged development of the 3 litre / 183 cui Cosworth DFV that dominated in Formula One from it’s introduction in 1966 to 1981. To meet the USAC regulations the DFV was downsized to 2650 cc / 161 cui and fitted with a Garrett turbo charger.

04 Image351sc

Engine designer Keith Duckworth described these motors as being like ‘hand grenades with the in pulled’. By the end of the DFX development programme the motors were producing 840 hp. Al Unser was also at the wheel of the last DFX powered car, a Penske, to enter victory lane at Indianapolis in 1987.

05 DSCN8500sc

Having won the 1978 Indy 500 Al Unser also won the two other 500 mile races in the USAC series at Pocono and Ontario becoming the first winner of the ‘Triple 500 Crown’. Al is seen driving the car above in the Daily Express 200 at Silverstone, England battling for the lead with Danny Ongias.

06 DSCN8507sc

Unfortunately the battle only lasted 4 laps, Ongias broke a drive shaft, Al led a good deal of the race but ran out of fuel right in front of me.

07 Indy80 027s

The T500 was used in Penzoil colours in early 1979 before Jim Halls Chaparral 2K was ready. In 1980 Jerry Sneva, seen in this photo by Ed Arnaudin, qualified 5th in this T500 and finished 17th in the Indy 500 two further T500’s were raced in this event driven by Tom Bigelow Q 31st F 8th and Gregg Leffler Q 23rd and F 10th.

Rained Off – Eagle Offenhauser 7400

As I mentioned yesterday the 1975 Indianapolis was won by Bobby Unser and today thanks to photo’s by Ed Arnaudin we can have a look at the #48 Eagle Offy 7400 driven by Bobby Unser, seen starting on the outside of the front row with #20 Gordon Johncock and #14 AJ Foyt on pole, that was declared the winner after 174 of the scheduled 200 laps.

1975 Indy 500

All American Racers which manufactured Eagle racing cars was set up initially by Dan Gurney and Carroll Shelby to tackle the World Championship Grand Prix circuit and the US Champ Car and Sportscar circuits in 1964.

In 1967 Dan Gurney won the Belgian Grand Prix in an Eagle Weslake Mk 1, also known as T1G, run by the firms UK based satellite team known as Anglo American Racers. The following year Bobby Unser won the Indy 500 in an Eagle chassis.

Upon retiring from the cockpit Dan Gurney bought Shelby out and in 1973 Gordon Johncock in an Eagle run by Pat Patrick was declared winner of the tragic rain shortened race, in which his team mate Swede Savage suffered injuries from which he would later die and a member of his pit crew was fatally struck in pit road by a fire truck going the wrong way down pit road to attend to the Savage incident.

Eagle Offenhaser 7400, Indy 500

By 1975 McLaren also with two Indy 500 wins were regularly challenging Eagle for overall supremacy on the USAC Champcar Circuit and this would prove to be the third and final Indy 500 victory for the Eagle marque.

It transpires that the Eagle chassis type numbering system is worthy of a large dense volume all of it’s own, however to the best of my knowledge the winning car that Bobby Unser car drove is a type 7400, if a chassis number becomes known to me I’ll add it below.

Bobby Unser is part of one US Racing’s elite families, he and his younger brother Al Snr competed on the Champ Car circuit in the 1960’s, 70’s and 80’s.

Bobby known as the ‘undisputed King of Pikes Peak’, counts among his many success 13 Pikes Peak hill climb victories, 8 of them in a ten year period, the ’68 and ’74 USAC Champ Car championships, along with his Indy 500 wins of ’68, ’75 and ’81.

In 1968 Bobby participated in two Grand Prix for BRM, after qualifying for the Italian Grand Prix he flew back to the United States and took part in the Hoosier 100 at Indianapolis, upon his return to Monza with fellow Italian GP qualifier Andretti, they were told that the rules forbade drivers to participate in 2 races less than 24 hours apart.

Eagle Offenhaser 7400, Indy 500

In 1975 Bobby also won the IROC championship to confirm his all round versatility.

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.

09 07 03 023sc

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.

Taxi Driver – Jim Robbins Eagle Ford T/C Mk 2

Continuing GALPOTS potted history of the Indianapolis 500 Ed’s photos shown here today were taken in 1969, when Ed Arnaudin took the opportunity to get good and close to the Jim Robbins team again.

Indy69 001s

The driver of the #67 Eagle Ford is Lee Roy Yarbrough, not related to Cale Yarborough, from Jacksonville, Florida.

Lee Roy is said to have won his first race at 19 at a local dirt track and progressed through the NASCAR Sportsman Division with 11 wins and onto Modifieds where he won 83 features in 3 years.

On reaching the top Grand National Division, today called Sprint Cup he won 14 races from 198 starts over 12 years. His best season was 1969 7 wins, including Darlington, Charlotte and both races at Daytona, from 31 starts in the seasons 54 races. Many retirements due to engine failure kept him out of the title hunt won by David Pearson.

Lee Roy made just three starts in the ‘Indy 500’ in ’67 ’69 and ’70 his best finish was in 1970 when he completed 107 laps and retired with turbo failure and was classified in 19th place.

His career, as were several others,was adversely affected by the withdrawal of Ford from competition and Yabrough disappeared from NASCAR after failing to secure a ride for the Daytona 500 in 1973, he was eventually admitted to a mental hospital where a fall inflicted a fatal traumatic brain injury aged 46.

#67 Lee Roy Yarbrough 1969s

Jim Robbins turned up at the Brickyard in 1969 with three vehicles the #10 and #27 Vollstedts and the #67 Eagle Ford Mk 2, seen here, a design inspired by UK free lance design consultant Len Terry. This vehicle appears to be one of several built in 1968, though at this stage I do not know it’s exact history prior to the 1969 race.

After Denny Zimmerman failed to get the #67 up to speed in 1969 Lee Roy Yarbrough moved over from his ride in the #27 Vollstedt to qualify 8th for the Indy 500, during the race a turbo pipe broke sending him into retirement and a final classification of 23rd.

Indy69 008s

All of Jim Robbins 1969 entries were powered by turbocharged Ford engines, a turbocharger had first been used at Indy in 1952 on the Cummins Diesel.

With the arrival of the normally aspirated 4,195 cc / 255 cui Ford V8’s in 1963, several Offenhauser powered teams turned to supercharging smaller 2,752 cc / 168 cui motors to remain competitive in 1965, following the lead set by Novi some years earlier.

A couple of Offenhauser powered vehicles had mechanically more efficient turbochargers fitted to these smaller motors in place of the superchargers in 1966. Bobby Unser drove his Eagle Offy to the first turbocharged victory at Indianapolis in 1968.

In 1969 Ford also went the smaller capacity turbocharged route and only three cars in the 33 car field of ’69 did not have smaller 168 cui engines with turbochargers fitted.

Note how the large turbocharger air intake on the left rear of the #67 is rearward facing so as to avoid the problems experienced by the Cummins Diesel turbocharger in 1952 which sucked up so much debris from its front facing turbo air intake that the turbines terminally failed on lap 40.

I’d like to thank Steve Arnaudin for scanning today’s photographs and Amphicar at The Nostalgia Forum for his help in identifying the car.

West Coast Detailing – Lotus XI

A couple of weeks ago I looked at Ed Arnaudin’s photo of Floyd Aaskov’s Lotus XI at Thompson CT taken in 1958, where you will find details about the Lotus XI model.

Lotus XI, Paramount Ranch, Carlyle Blackwell

Photo Carlyle Blackwell, Publised Courtesy Blackwell Archive, for sales enquiry’s please e-mail infoATpsychoontyres.co.uk and your contact details will be forwarded to the Blackwell Archive.

Today we are looking Carlyle Blackwell’s photograph of Jack Nethercutt’s Lotus XI at Paramount Ranch in 1956/57.

It would appear that Jacks Lotus XI ran a similar 4 cylinder 1098 cc /67 cui Coventry Climax engine to Floyd Aaskov. One thing that stands out about Jacks car is how amazingly clean it looks, it looks as well detailed in many other photographs I have seen of this vehicle.

Records indicate that Jack Nethercutt started racing in 1956 with a Mercedes Benz 300 SL, oddly records indicate Floyd Aaskov started racing in a similar model 12 months later on the east coast. In 1957 Jack started notching up regular GM class wins on the West Coast and in 1958 he acquired a Ferrari 500 TRC with which he started winning in the 2 litre / 122 cui EM class.

In 1959 Jack upgraded his 500 TR by fitting a 2.5 litre motor in and running in the 152 cui DM class in which he continued his record of accumulating class wins.

For 1960 Jack took delivery of a Ferrari 250 TR 59 with which he again took class wins in the 187 cui S1 division including a third overall in the Sebring 12 Hours. Half way through 1961 Jack swapped his Ferrari for a Lotus 19 and again running in the DM class continued his winning ways until 1964, taking a class win at the ’62 Riverside 6 hours with a one off drive in a Morgan plus 4 along the way.

Records show that Jacks career ended in 1965 driving a Mirage Oldsmobile in the over 5 litre / 305 cui class still carrying the #102 but without much in the way of success.

Jack appears to have settled for running a Mirage Chevrolet for Scooter Patrick in the first Can Am championship in 1967.

A similar photograph by Carlyle Blackwell to photograph above appeared on the cover of Road & Track in March 1957.

Lotus XI, Paramount Ranch, Carlyle Blackwell

The caption read “It was dry and hot at Paramount Ranch, near Los Angeles, the day Carlyle Blackwell shot our March cover – but no hotter than the Lotus Eleven, driven here by its owner, Jack Nethercutt.”

My thanks to Ed Arnaudin who purchased the photograph in the 1950’s and to his son Steve for sending me the scan, thanks also to Jean L and JB Miltonian at the TNF Forum for their help in identifying the track and coming up with the R&T; details.

Broken Promises – DB Panhard HBR

Somehow almost overlooked this photo by Ed Arnaudin of John B Mull in his DB Panhard competing in Race 1 at Thompson CT on the 20th July 1958, although John did not finish this race, we shall see this is a significant model in the world of national and international class H up to 750 cc 45.7 cui racing.

The manufacture of DB cars commenced after a promised drive failed to materialise at the 1936 French Sports Car Grand Prix for Charles Deutsch and René Bonnet. The following year they entered a special of their own devising using the remnants of of a Citroen Traction Avant 11 CV.

Their specials placed in the very first post war race in Paris in 1945 and with the construction of the open wheel DB7 Automobiles Deutsch & Bonnet became a business entity in 1947.

Unhappy with the supply of Citroen parts they switched primarily to using flat twin Panhard motors of 744 cc / 45.4 cui. DB Panhards took class victories at the Mille Miglia, four times, Le Mans, three times, Sebring, twice and SCCA class H, the latter in 1958 with Howard Hanna at the wheel and in 1959 with Ray Heppenstall at the wheel.

Despite their on track success after building nearly 1000 vehicles, a disagreement over the architecture of their next model led to Deutsch and Bonnet going their separate ways forming CD and Automobiles René Bonnet respectively, the latter using Renault power became part of Matra Automobiles in 1965.

Panhard which as Panhard et Levassor had been in business since 1897 was absorbed in to Citroen in 1965 with the last vehicle produced in 1967 the name is still to be found in use as a brand of French built military vehicle.

The HBR model seen here was built from 1954 to 1961 on the most common DB chassis shared with Mille Miles and Coach models of which a combined total of 660 were made.

John B Mull appears to have had a collection of vehicles to race with Evelyn Mull between them they are known to have raced a Jaguar XK120, AC Ace Bristol, Austin Healey 100 S and this DB Panhard, JB is also known to have raced an OSCA S750.

Hope you have enjoyed the Race 1 Thompson CT 20th July 1958 series, my thanks to Ed and Steve Arnaudin for the photograph and to Terry O’Neil for the race results. Join me tomorrow for Ferrari Friday when we will be looking at a vehicle driven by a reigning 3 time World Grand Prix Champion on it’s victorious debut and a month later was driven to a class victory by the USA’s first future world champion.
