Triumph built four racing Spitfires to compete in 1964 and 1965 Le Mans 24 Hours race; the fourth being a spare (but the fourth raced in 1965). With Porsche, now reputedly achieving 160mph, Triumph embarked on building a six cylinder racing Spitfire for the 1966 event to stay competitive with them. This prototype was to be called the GT6R and was to run a highly tuned six cylinder engine fitted with triple carburettors. 175 bhp was confidently expected to give an estimated top speed of 160 mph but in early 1966, due to regulation changes, the programme was run down and the project was abandoned.
This extraordinary motor constructed on a 1963 Triumph Spitfire using all composite T6 Fabrications bodywork has had ongoing development since its inception and includes a fabulous specification. Its registration number echoes the period competition Spitfires who wore the ADU number plates. The car is fitted with a rebuilt, 2.0 litre straight six Triumph engine with a Peter Burgess head, Le Mans oil filter, a Type 9 close ratio five speed gearbox and a Quaife limited slip differential. Fuel is delivered via an electric pump feeding the triple 40 DCOE Dell'Orto carburettors. Exhaust extraction is by means of a tubular extractor manifold through a full stainless steel system. A 123 distributor provides the sparks and an aluminium radiator and oil cooler provide the cooling. Stopping power is delivered by Lockheed four pot callipers and ventilated discs at the front with GT6 drums at the rear. The brake system has an adjustable biased twin circuit, as per the original prototype. The front suspension has the Lotus trunnionless set up with aluminium hubs. At the rear, CV drive shafts and an aluminium lower wishbone conversion stop the infamous Spitfire rear wheel tuck under. Gaz adjustable shock absorbers are fitted on all four corners. The interior is fitted with a half roll cage and new FIA four point harnesses with bucket seats. The instrument panel has several gauges to keep the driver well informed and a Moto-Lita leather/aluminium steering wheel provides directional control. An aluminium period replica fuel tank sits behind the seats and is fed a via large, quick release Le Mans style fuel filler.
