Porsche 956 Brun
Outro Porsche, agora o 956C do Stefan Bellof, kit da Revell na escala 1/24. In mid 1981 Porsche started to design a two-seat racing sports car in accordance with FIA rules, which revoked separation into groups 1 to 6 and set new requirements for prototypes for the World Championship from 1982 onwards. The new rules limited fuel consumption and were also concerned with the power take-off of the vehicle. This caused the design to focus on aerodynamics . The porsche 956, thanks to its specially shaped air ducts, achived as effective negative pressure on the floor of the car, which gave the vehicle a cornering speed that had previously been impossible. The car has a monocoque chassis, built in such a way that the components as far as possible out of the air stream but are still able to withstand the enormous loads produced by the power take-off. According to the FIA provisions for overall lenght to wheelbase, which prohibit version with extremely long rears, Porsche selected the longest ever wheelbase for a Porsche race car of 2600 mm. Thus the 956 received a new, all-syncromesh gearbox, but its 6 cylinder horizontally opposed engine with twin turbocharges, 800 kg weight and 2.65 litre capacity had already proved itself in the 936 and was therefore taken over without modification. The 956C was an immediate success, although 1982 was only intended as a trial year. In fact the Group C era was to become a period of huge motorsports succes for Porsche. In the year of their debut, well ahead of the competition, the team from Zuffenhausen won the Constructor’s title in the Sportscar World Championships, broke the distance record at Le Mans and won three 24 hours races. In 1983 the 956 C electronic fuel injection, the compression of the engine was increased thus giving in higher performance, so that its capacity could be increased by 20 bhp to a total of 640 bhp. Again the 956 dominated group C at speeds of over 350 km/h. Alongside the well-known drivers Ickx, Mass, Stuck and Winkelhock, the 25-year-old Stefan Bellof joined the Porsche works team. He immediately won his first race, producing an amazing average speed of over 200 km/h in the 1000 km race on the northem loop on the Nürburgring, a record that is unbroken to date. In 1984 the man from Gienssen, in the meantime driving for Tyrrell in F1, became long distace World Champion, European Champion Driver and also won the International German Racing Championship in the 956C . In 1985, Bellof, the first German driver to succeed in taking a world championship title on the circuit, changed to the private racing stable of Walter Brun whose 956C he drove in motor races. After nine F1 races, which would also have got him an offer from Ferrari for the following year, this promising and successful talent had a fatal accident on 1st September in the long-distance race at Spa Francorchamps.
