The Porsche 934 was developed in 1976 in order to compete in the Group 4 GT category of national and international events. It dominated the 1976 European GT and Trans-Am championships and went on to take countless other successes in the hands of Porsche’s many private GT racers. In 1979 a 934 won the Group 4 category at Le Mans, coming fourth overall.
The 934 described here, the fourth built, was originally campaigned under the Denim colors and known as ‘The Jeans Car,’ under which guise it raced in the German championship and W.E. Races in 1976 and 1977. Pictures of this car will be found in the authoritative Porsche: Catalogue Raisonee and Chris Harvey’s Great Marques: Porsche. It was brought to the UK in 1978, and took part in the Silverstone 1000 Km driven by Tony Dron, also competing in several other endurance events. At this point it was road legalized by the fitting of an RSR engine for the Intermarque Series.
The last owner purchased the car in 1982 and raced it in the Intermarque Series and various club events. After this, in 1987, a Group B 3.3-litre turbocharged engine (a Le Mans spare) replaced the RSR unit as part of a full restoration by Neil Bainbridge, since when it has been used only for demonstration purposes such as the Monza International and Varano meetings last year. Among its features are fiberglass front fenders, coil sprung 935 type suspension, huge AP calipers, a modern fire extinguishing system, exhaust temperature gauge, 100-liter bag tank and so on. The engine has shown 320 bhp on dyno test with no boost, and produces a massive 480 bhp with full boost.
The car’s condition is described as excellent in every respect, and it is said to be “on the button,” ready for immediate use.
The car comes with a V5 logbook, a history file and an extensive AutoCapital track test article conducted in 1993.
