Happy Birthday Cheryl – Marcos Mantis GT2

After the successes of the Rover V8 powered Mantula Rover based Marcos LM400, LM500 and LM600 GT cars which won the 1995, 1996 and 2000 British GT Championships Marcos announced the Dunlop sponsored spec Mantis Challenge in 1998 with spec normally aspirated quad cam Ford V8 motors.

In 2002 racers Warren and Charlotte Gilbert (nee Osborn) established Topcats Racing in Westcott, Buckinghamshire which has become a leading contender on the British Endurance GT seen and a leading independent service center for Caterham, Corvette, Lotus, Marcos and Mosler cars offering everything from a full service to an LS7 engine transplant.

Today’s featured Britcar Class 2 Marcos Mantis is built around a space frame with a fiberglass body and is powered by a standard LS7, 7 litre / 427 cui V8 engine mapped to produce 505hp on 98 octane unleaded fuel which is transmitted to the rear wheels through a 6 speed Holinger sequential gearbox.

Additional features include electric power steering, quick fill fuel tanks, quick lift air jacks and spec 18″ Dunlop slick or wet tyres on center lock wheels, four of which can be changed in 22 seconds.

With a weight of 1050 kgs / 2315 lbs the car will reach 60mph in an ear splitting 3.5 seconds and a top speed of 190 mph.

Sam Head and Kyle Tilley drove the #26 car entry for most of 2011 and they are seen above at Castle Combe on the 27th of August where they finished a low 20th overall from a more representative 8th on the grid, this a month after Henry Fletcher and Raphael Fiorentino had finished 2nd overall and 1st in Class 2 at Spa.

At the seasons end the Topcats Class 3, 50 hp less, #36 Mantis finished 2nd in the Britcar Championship with Owen O Neill, Henry Fletcher, Jon Harrison and Raphael Fiorentino all taking turns at the wheel during the season and the #36 was classified 3rd with Jeff Wyatt replacing Kyle for one round at Snetterton and Neil Huggins and Jon Harrison being the cars drivers in the championship final at Brands Hatch.

Topcats appear to have retired their LS7 powered Mantis cars from competition at the end of 2012 after their 2 cars both now running in Class 2 finished 3rd and 11th in the Britcar Championship.

Wishing Cheryl a Happy Birthday.

Sprinzel Lawrence Racing – Morgan And Triumph SLR

Towards the end of 1963 former British Rally Champion and Racing Driver John Sprinzel joined forces with noted engineer and Morgan racer Chris Lawrence, under the Sprintzel Lawrence Racing (SLR) banner, to design and build a sports car based on a Triumph TR4 powered ladder frame Morgan +4, with a similar chassis to the one that Chris had co driven with Richard Shepherd – Barron to a class victory at Le Mans in 1962.

From what I can gather Triumph racer John Hurrell managed to secure some funding for the SLR team and after seeing Chris Spenders drawings for the proposed Williams and Pritchard built bodywork for the Morgan & Triumph SLR car John asked if a similar SLR body could be fitted to his Triumph TR4 that he had been racing since 1960.

As things worked out the Triumph with a slightly shorter chassis was the first to be taken to Williams and Pritchard to have an aluminium SLR body built around it. Neil Dangerfield is known to have been winning races in this car as late as 1967 and the Triumph SLR went down in the record books as being the last to leave the start line at Goodwood as the scratch entry in the last, handicap, race held at the Circuit before it closed in 1966.

Neil drove the Triumph SLR 31 years later at the request of Lord March on a 3 lap demonstration when the Goodwood circuit was reopened in 2006.

Note the registration SAH 137 was originally issued to a Triumph TR3A owned by Jim Hurrell who transferred the number to the Triumph TR4 that was fitted with the SLR body and later sold it to Neil.

The first of the Morgan SLR’s powered by a Triumph TR4 engine and featuring beefed up hubs along with the benefits of other lessons learned from Chris Lawrence’s Le Mans experience appears to have been built around a 1961 chassis for Gordon Spice a well known figure in British racing circles who eventually built and ran his own Spice Group C cars in the late 1980’s.

After just 3 laps of Goodwood Gordon crashed his new car in 1964, necessitating a complete rebuild making this red car both the first and last of the Morgan chassied SLR’s built. In 1975 then owner Sir Aubery Brocklebank suffered burns after a fuel leak in this car caught fire at Silverstone. The car was subsequently painted fire engine red.

The second Morgan and Triumph SLR was built for Pip Arnold, legend has it that this car was never painted because soon after delivery it was due to be raced at Spa and so the aluminium bodywork was merely polished. In the early seventies this car was caught in a severe garage fire and rebuilt by well known fabricator of racing cars Maurice Gnomm.

The third car was built for Chris Lawrence himself and set an all time class lap record at the very last race meeting held at Goodwood in 1966. Chris Lawrences old car also won a race during the Goodwood Revival in 2006.

All three of the Morgan And Triumph SLR’s were united possibly for the first time ever at the 2010 Silverstone Classic. As John Sprinzel rhetorically asked after seeing these photo’s “They were good looking cars weren’t they?”

From The Nostalgia Forum I’d like to thank David Lawson and Bob ‘Bauble’ Bull for the use of their photographs, Pete Stowe, Kurt O and Sharman for responding to my TNF Triumph SLR thread garyfrogeye for contacting John Sprinzel and Tim of the Willliams and Pritchard website for their kind replies.
Thanks also to Andy Downes and in particular Neil Dangerfield of the tr- register forum for his post on the order in which the cars were built to Richard ‘redmorgan’ Gilbert for the use of his photo, John “sprinty” and Steve N22MOG L and everyone at Talk Morgan who responded to my post.

Thanks for joining me on this SLR edition of ‘Gettin’ a lil’ psycho on tyres’ I hope you will join me again tomorrow for a look at an exotic Italian that needs a cool pagoda airbox to cover a big block V8. Don’t forget to come back now !

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.
