Magna Detailing – Maki F101

When the Maki F101 was announced in 1974 my first reactions were similar to the announcement of the Eifelland two years earlier, such unfettered enthusiasm for something so different from anything else of course does not always pay dividends as Lotus were two find out with their ultra thin Lotus 76 in the same year.

Maki F101, Goodwood Festival of Speed

The Maki project was founded by Kenji Mimura who is credited with designing the Ford Cosworth DFV powered car with Masao Ono. The details of some of the features are at once both like something out of a Magna Comic and extremely futuristic, bearing in mind that this was a time when the biggest selling road cars like the Ford Cortina and Morris Marina were little more than 3 boxes with wheels on.

By the time the F101 now in B Spec made it’s dedut with Howden Ganley driving at the 1974 British Grand Prix it had already shed it’s unique body work for something rather more conservative.

Howden, seen at the wheel above during at the Gooodwood Festival of Speed, while not driving the slowest car in practice failed to qualify for the British Grand Prix.

At the German Grand Prix disaster struck when the during the first day of practice the rear suspension failed sending Howden into the crash barriers which ripped the front of the car off.

Amazingly Howden stepped out of the wreckage unaided but his ankles were seriously damaged and this was to be the end of his Formula One career.

The Maki F101 did not appear again in 1974 but a C variant did appear with a new chassis in 1975, the story of which will have to wait for a future edition.

Howden Ganley recovered from his injuries and went on to found a successful racing car manufacturer with fellow F1 refugee Tim Schenken called Tiga.

Under The Hood Details – Niello Concours at Serrano

On October 5th Geoffrey Horton took his Jaguar XK 140 to Niello Concours at Serrano where it was shown in the special display class.

Jaguar XK140, Niello Concours at Serrano

Any one interested in what is under the hood of Geffrey’s Jaguar can see it by following this link.

National, Niello Concours at Serrano

Today’s post will focus on what was lurking under the hood of some of the other vehicles on display, above the 1911 National Indy 500 car only had 4 cylinders but with a displacement of 7.5 litres / 460 cui they still packed a 100 hp punch.

Allard K2, Niello Concours at Serrano

I beleive this is the third appearance of this particular 1951 Allard K2 on this blog, but the first appearance of it’s 5.4 litre / 331 cui Cadillac overhead valve motor with three original Stromberg carburetors that produce around 160 hp.

Plymouth Fury, Niello Concours at Serrano

The 281st, off the production line, 1956 Plymouth Fury above boasts a 5 litre / 303 cui polyspherical head V8 with optional twin 4 barrel carburetors which combined to produce 270hp.

Chrysler 300F, Niello Concours at Serrano

For 1960 Chrysler introduced the 6.8 litre / 413 cui wedge motor for the 300F seen above. To maximise power in low to mid rpm range the motor was fitted with tuned 30 inch intake pipes which were fed by the carburetors from opposite sides.
The air resonances inside the air intake pipes helped to force air into the cylinders at low to mid range rpm and thus increase the power which topped out at 375hp.

Lotus 27, Niello Concours at Serrano

Not completely off topic I was reading some information about the early days of racing recently and discovered that while Voiturettes were generally restricted to 1.5 litre / 91.5 cui motors there was a smaller class known as Cycle Cars which were restricted to 1.1 litres / 67.1 cui which would make the much later 1963 Formula Junior Lotus 27 above the equivalent of a cycle car in Veteran times. The motor for this Lotus is clearly a Ford production block with a Cosworth head. Power for these motors has risen from 36hp in original side valve production form to 115 hp quoted by some tuners for a competitive Formula Junior with the Cosworth head.

Lotus 19, Niello Concours at Serrano

In late 1963 Lotus built the last Lotus 19 B chassis #966 uniquely powered with a 4 carburetor 4.7 litre / 289 Ford V8 motor for Dan Gurney. The car was quick, but unreliable and Dan never recorded a win with it although it’s next owner Steve Diulo managed a win at the SCCA Willow springs race in December 1965. The cars last appearance was at Texas International Speedway in November 1969 where Bruce Campbell was running but unclassified in chassis #966 by now rebranded as a BVC Mk 1 and with a Chevrolet motor installed.

Ford Mustang GT 350, Niello Concours at Serrano

Finally, for this week, above is another Ford V8 this time a 306hp 4.7 litre Shelby tuned Ford HiPo 289 inside one of the 252 “carry over” 1965 Shelby Mustang 350 GT’s which feature ’65 Ford VIN numbers and ’66 Shelby VIN numbers.

My thanks to Geoffrey Horton once again for sharing his photographs from the California Concours d’Elegance scene through the year.

Thanks for joining me on this “Under The Hood Details” edition of “Gettin’ a li’l psychoontyres” I hope you will join me again tomorrow when I’ll be looking at a 3 ton pickup that gets up to 60mph from rest in just 5 seconds. Don’t forget to come back now !

Classic & Retro Action Day – Castle Combe

The day after attending Goodwood Festival of speed David Roots invited me along to Castle Combe for the Retro & Classic Action Day which was a mixture of car show and track day.

MG TC, Classic & Retro Action Day, Castle Combe

In between the rain and thunder there was a fascinating array of vehicles to see like this 1946 MG TC.

Healey Duncan Drone, Classic & Retro Action Day, Castle Combe

Like some of the storied vehicles at Goodwood, some at Castle Combe had tragic tales to tell. The Healey Duncan Drone was built with a throw away body to keep the list price, and attendant 66% taxes, down on the domestic market. Extras for this car would have included a second seat and the spare wheel. This particular car took the start of the 1949 Mille Miglia at 6:25 am with James Cohen and Reg Hingett aboard. 35kms later Reg was dead after their car collided with a bridge and while James would eventually be repatriated back to the UK, he too would succumb to his injuries.

Ford Squire Cosworth, Classic & Retro Action Day, Castle Combe

In Latvia the Ford Prefect was built under licence as the Ford-Vairogs Junior I am not sure they would have had an estate / station wagon variant because the UK Ford factory was so busy they farmed out production of the Prefect Estate known as the ‘Squire’ to the coach builders Abbots of Farnham who were given brand new off the assembly line Prefect saloons / sedans to convert. This particular vehicle, built in 1960, is officially shown as no longer having it’s original 1,172 cc / 71.5 cui side valve motor good for 71 mph, but instead the official capacity is given as 1993 cc / 121.6 cui which is usually the sign of the presence of a 200hp motor taken from a Ford Sierra Cosworth or similar.

Datsun Fairlady 1500, Classic & Retro Action Day, Castle Combe

Before Datsun got the Jaguar E-Type inspired Fairlady ‘Z’ series up and running in 1970 their sports cars tended to follow the lines of the slightly more mundane MG’s and Triumph’s of the day. Above is a 1965 Fairlady with a 1500 cc / 91.5 cui 4 cylinder motor.

Ford Escort Cosworth Estate, Classic & Retro Action Day, Castle Combe

In 1969 I was lucky enough to travel overland from Durban in South Africa to Mufulira in the back of a Ford Escort Estate Mk 1 with my folks, over following holidays we made it as far as Malindi in Kenya in the same car. In 1977 when my folks came back to the UK they bought a Ford Escort Estate Mk II not unlike the one seen above. The gentleman who own’s the yellow car tells me it was his first car, unlike my folks, he has swapped out the original 1300cc / 79.3 cui motor for a 200hp Ford Sierra Cosworth unit which would probably get him from Durban to Malindi days if not a week faster than we could ever have hoped to do it.

ALFA Romeo 33 Cloverleaf 2, Classic & Retro Action Day, Castle Combe

My first visit to Castle Combe in 1987 is indelibly linked to the memory of friends race winning #143 ALFA Romeo 33 which got wrecked, after he had abandoned the car at Quarry, by an errant ALFA Sud. My friend was unhurt and he came back toward the end of the season with another car to score a win. Seeing the later Red ALFA Romeo Cloverleaf 2 33 above in the paddock brought those memories flooding back like it all happened yesterday.

TVR Tamora, Classic & Retro Action Day, Castle Combe

Finally I was parked opposite this lush Opal White Pearlescent TVR Tamora and couldn’t take my eye’s off it while sat in my car waiting for the thunder and rain to abate. The owner tells me that while the car was undergoing various mechanical upgrades by ex TVR factory personnel he had the car resprayed, at £300 pounds a tin the paint is not cheap the whole respray came in at an eye watering £7,500. About ten times the value of my Golf and probably two or three times the sum I have spent on every one of the twenty or thirty cars I have ever bought combined ! Still it was without question worth it, there is only one other Tamora painted the same colour.

My thanks to David Roots for inviting me along to Castle Combe.

World Champions At Last – McLaren Cosworth M23 #M23/4

The final destination of the 1974 World Drivers Championship was in doubt until the lastof the season with Jody Scheckter driving for Tyrrell, Clay Regazzoni driving for Ferrari and Emerson Fittipaldi driving for McLaren all in with a shout.

McLaren Cosworth M23, Race Retro, Stoneleigh

Emerson Fittipaldi sealed the deal with a fourth place finish at the US Grand Prix which along with wins in Brazil, Belgium, Canada and six further points scoring finishes gave him a 3 point advantage over Clay Regazzoni who failed to add to his points tally at Watkins Glen.

McLaren Cosworth M23, Race Retro, Stoneleigh

For 1974 McLaren had lengthened the wheel base and widened the track of Gordon Coppucks M23 design which was first seen in South Africa in 1973.

McLaren Cosworth M23, Race Retro, Stoneleigh

McLaren had also attracted Philip Morris sponsorship that had previously gone to BRM and managed to leverage Texaco sponsorship along with 1972 World Champion Emerson Fittipaldi from Lotus.

McLaren Cosworth M23, Race Retro, Stoneleigh

Denny Hulme was Emerson’s team mate and he contributed to McLaren winning their first World Constructors Championship, at their 9th attempt, by winning the opening race of the 1974 Championship season in Argentina.

McLaren Cosworth M23, Race Retro, Stoneleigh

So far as I have been able to ascertain today’s featured car is the forth M23 chassis, which was first raced in the 1973 German Grand Prix when Jacky Ickx made a one off appearance for the team and drove it to a third place finish behind the Tyrrell’s of Jackie Stewart and Francoise Cevert.

McLaren Cosworth M23, Race Retro, Stoneleigh

Peter Revson then drove #M23/4 to a third place finish in the Italian Grand Prix a win in the Canadian Grand Prix, which would prove to his last Grand Prix win, and a 5th place on his final drive for McLaren in the 1973 US Grand Prix.

McLaren Cosworth M23, Race Retro, Stoneleigh

Emerson Fittipaldi best results with #M23/4 in 1974 were a 3rd place in the 1974 Race of Champions and a 4th place finish in Sweden, after Mike the Bike Hailwood’s crash at the 1974 German Grand Prix #M23/4 reverted to Yardley colours for the remainder of 1974 to be driven by David Hobbs in Austria and Italy and Jochen Mass in Canada and the United States. With Mass scoring a 7th place at Watkins Glen that matched the older Hobbs 7th place finish in Austria the young German secured himself a ride as Fittipaldi’s team mate to replace the retiring Denny Hulme for the 1975 season.

McLaren Cosworth M23, Race Retro, Stoneleigh

#M23/4 only made two appearances in the 1975 season in the non championship International Trophy at Silverstone where Emerson finished 2nd and in the 1975 German Grand Prix where Jochen retired after an accident on the opening, which is said to have reduced #M23/4 to “vitual scrap”.

At Stonleigh #M23/4 appears in these photographs with the correct 1974 colour scheme and early season airbox, extended side pods as fitted to Jochen’s car in the 1975 German Grand Prix but curiously the extended side pods have orifices which did not appear until the Spanish Grand Prix in 1976.

Note: Jochen took the start of the 1975 German Grand Prix in #23/4, distinguished at this meeting by it’s white front wings and hastily applied black #2 race number on the side pod, according to contemporary reports by Dennis ‘DSJ’ Jenkinson and not #M23/6 as indicated by RacingSportsCars.com

My thanks to BSC at The Nostalgia Forum and Allen Brown at OldRacingCars.com for their help identifying the chassis number of today’s car.

IR, FW or Apollon Fly – Williams Cosworth IR/03 / FW/03

Ever asked a question of fact and got a different answer dependent upon whom is answering ? Ask any number of people what today’s car is and they will agree it is a 1973/4 Williams but after that it gets complicated.

The Williams IR series cars first appeared at the 1973 Spanish Grand Prix replacing the FX3B Williams design, known in 1972 as Politoys, that did not have deformable structures protecting the fuel tanks. The IR initials were a nod to one of the teams sponsors namely ISO Rivolta.

01 Williams Cosworth IR/04_0130sc

A new car, IR/03 featured today, to the same design as the 1973 cars, appeared at the 1974 Spanish Grand Prix for Arturo Mezario. Denis Jenkinson (DSJ) correctly reported after the Spanish Grand Prix that Frank Williams had renamed the cars with FW initials, but either idiosyncratically or incorrectly that the latest chassis IR/04 was hence forth to be known as FW/04.

DSJ continued referring to IR/04 until the 1975 non championship Race of Champions. However DSJ was possibly confused by the fact that the original IR/02 was damaged and the chassis tub replaced during repairs. While the new car seen at the 1974 Spanish Grand Prix was built around the 4th IR tub it was given the IR/03 chassis number and post the Spanish Grand Prix this fourth chassis seems to have been referred to by everybody apart from DSJ as FW/03.

02 Williams Cosworth IR/04_0129sc

DSJ correctly referred to this car as FW/03 at the non championship 1975 International Trophy and correctly mentions that the new car driven by Art Mezario at the following 1975 Spanish GP as FW/04 !

As if to confirm the respected DSJ’s error no mention is made of chassis IR/04 / FW04 in a MotorSport article about cars entered by Frank Williams from 1969 upto April 1975.

03 Williams Cosworth IR/04_0128sc

Today’s featured car’s best result came in the 1974 Italian Grand Prix where Art Mezario managed to coax IR/03 / FW03 to a fourth place finish at Monza.

This result plus Art’s sixth place finish in South Africa were enough to secure Williams a second consecutive 10th place in the 1974 World Constructors Championship.

04 Williams Cosworth IR/04_0127sc

During 1975 Tony Brise, Damien Magee, Ian Scheckter, Francois Migault, Ian Ashley, the seriously obscure Jo Vonlanthen and Renzo Zorzi all drove IR/03 / FW/03 without much success, Brise recording a best 7th place finish in the 1975 Spanish GP on his Formula One debut.

In 1977 IR/03 / FW/03 now belonging to Swiss Loris Kessel turned up at the Italian GP with a raft of safety upgrades and some cool new body work by ex Ferrari designer Giacomo Caliri from his FLY-studio. Renamed the Apollon Fly Loris failed to qualify for the race, IR/03 / FW03 was restored to the 1974 spec seen here in 2010.

My thanks to Michael Ferner at The Nostalgia Forum for confirming DSJ’s idiosyncratic refferences to IR/03 / FW/03 as IR/04 / FW/04.

Son Of Lobster Claw – Trojan Cosworth T103 #T103/1

After the successes of the 1973 Trojan T101 Formula 5000 car, particularly in the hands of Jody Schekter in the USA, the company Chairman Peter Agg asked Ron Tauranac to design an all new car for 1974 which would be suitable for F5000, the T102, and Formula 1, the T103 although the Chevy V8 in the former would not be able to be fitted as a fully stressed member as the Ford Cosworth DFV used to power the latter.

Trojan Cosworth T103, Silverstone Classic, Silverstone

Both the T102 and T103, seen above at last years Silverstone Classic, bore a strong resemblance to the Brabham BT34 Lobster Claw formula one car which Ron designed for the 1971 season.

Trojan Cosworth T103, Bonny, Silverstone Classic, Silverstone

Powered by the, as good as, ubiquitous Ford Cosworth DFV with an equally, as good as, ubiquitous Hewland DG300 gearbox the T103 attracted a minimum of sponsorship from Suzuki GB and Australian Tim Schenken was signed up to drive the car.

Trojan Cosworth T103, Silverstone Classic, Silverstone

Like the Amon Cosworth AF101 I looked at last week the Trojan T103 made it’s debut at the 1974 Spanish Grand Prix where Tim qualified 25th, 2 spots behind Amon, but stayed in the race for 54 more laps than Chris before spinning off on oil on lap 76, eight laps early, to be classified 14th.

Trojan Cosworth T103, Silverstone Classic, Silverstone

At the Belgian Grand Prix Tim brought the car home 10th and at Monaco Tim qualified 24th on the 25 car grid only to be involved in an incident that removed seven cars from the race on the opening lap. The team was refused an entry for the Swedish Grand Prix, failed to qualify for the Dutch Grand Prix, missed the French Grand Prix and turned up at the British Grand Prix with a new cockpit surround and Ferrari 312 B3 style single piece front wing.

Trojan Cosworth T103, Silverstone Classic, Silverstone

Tim qualified 25th for the British Grand Prix but but was sidelined with a suspension problem on lap 6. Tim and the Trojan proved unequal to the task of qualifying for the German Grand Prix at the Nurburgring, but bounced back by qualifying 19th in Austria where he finished a season equal high 10th. The cars final appearance before the money ran out was at the Italian Grand Prix where Tim qualified 20th and completed 15 laps before the gearbox cried enough.

That was pretty much the end of Trojan too, a company that founded in 1914 survived as a manufacturer in it’s own right until the the 1960’s when it started manufacturing first Heinkel bubble cars, then Elva sports racing cars and later McLaren Sports and open wheel racing cars under licence and then manufacturing a hand full of open wheelers of it’s own devising. The company was not dissolved until 2013.

Tim Schenken’s final Grand Prix appearance came in the 1974 US Grand Prix where he failed to qualify the unloved Lotus 76 27th but took to the grid when it looked like Mario Andretti’s Parnelli would not start but eventually turned up late grid to take his rightful place. Tim took the start only to be disqualified.

Tim eventually hooked up with Howden Ganley to found Tiga a successful company making racing cars for the junior open wheel and sportscar classes. A Tiga chassis tub was started for a Formula One car but it was never finished. Tiga would also become a successful Group C2 and IMSA Lights manufacturer.

The T103 is seen being driven by owner Phillipe Bonny at last years Silverstone Classic above.

Backyard Hi Tec – Amon Cosworth AF101

This month’s Sunday posts will feature 5 Formula One cars that ran in the 1974 season for which the then 31 year old Le Mans winner Chris Amon decided to follow in the foot steps of Jack Brabham and Bruce McLaren by building a car bearing his own name.

Amon Ford F101, Maydon, Siverstone Classic

It would appear Chris had plans to build both Formula 1 and Formula 5000 cars the latter to race in the lucrative US series with up and coming Australian Larry Perkins; a driver, engineer and sofa surfer who was making his way through the junior ranks in the UK. However despite financial backing from amateur racer John Dalton only the Formula One spec AF101 featured here ever saw the light of day.

Chris commissioned Gordon Fowell to provide him “with a sophisticated chassis” powered by a Ford Corsworth DFV motor driving the rear wheels through a Hewland gearbox. Gordon had designed the attractive, if underpowered, Martini sponsored 1973 Tecno E731 that Chris drove in practice at three meetings in 1973 but had never raced.

Amon Ford F101, Maydon, Siverstone Classic

The AF101 chassis, fabricated by Thompson who were also responsible for fabricating the Tecno E731 and Ferrari 312 B3, was certainly sophisticated with unique, for the time, central fuel cell that would become deriguer once ground effects were better understood with the introduction of the Lotus 79 in 1978. The car also had titanium torsion bar suspension and inboard front brakes, as did the well proven Lotus 72.

Responsibility for the aerodynamics was handed over to Professor Tom Boyce, and almost every time the car appeared it had a different nose including a high wing when it was first tested, a chisel nose in Spain where it first raced, a shovel at Monaco where the car qualified but did not race and then a lower full width wing was tried when the car failed to qualify in Germany and Italy.

Amon Ford F101, Maydon, Siverstone Classic

Unfortunately the AF101 proved a little to sophisticated for Chris’s budget, despite Larry Perkins saving a fortune in hotel bills with his sofa surfing skills, the little team folded having clocked just 22 laps in the 1974 Spanish Grand Prix before a brake shaft broke. Looking back on the project Chris conceded that he had attempted to build, what turned out to be a fragile hi tec vehicle on a backyard budget when he might have achieved more with a vehicle that was a little less ambitious and a little more reliable.

Larry Perkins loyalty was rewarded with an attempt at qualifying the Amon in the German Grand Prix after Chris was taken ill, unfortunately the combination of the Nurburgring, a rookie driver and a fragile car proved too much of a challenge for the team.

Amon Ford F101, Maydon, Siverstone Classic

After out qualifying Ricky von Opel and his works Brabham BT44 in the 1974 Spanish Grand Prix Chris was offered the second works Brabham drive for the rest of 1974, but turned it down out of loyalty to his own employees. Just as in 1973 when Tyrrell stepped in to offer Chris a couple of end of season drives after the demise of the Tecno team, at the end of 1974 BRM stepped in to offer Chris a couple of drives in the wonderful BRM P201, a model I’ll be looking at in a couple of weeks.

Post Italy 1974 the Amon was abandoned, restored and languished in a German Museum before it was restored to running condition in 2005. It is currently owned and raced by Ron Maydon in the Grand Prix Masters Series, Ron is seen driving the AF101 at Silverstone a few years ago.
