Mechanically, the Procar M1s were extensively modified to meet the requirements of circuit racing. The standard M1 featured the cast iron block BMW M88 straight-6 with 3,453 cubic centimetres (210.7 cu in) displacement.[8] Modified into the M88/1 by a team led by Paul Rosche,[10] it was capable of producing 470 horsepower at 9000 rpm,[8] compared to 277 hp from the standard M1's engine. The 5-speed ZF gearbox housing from the road car was retained,[8] but with multiple gear ratios allowed, as well as its own oil cooler.[1]
The suspension was entirely new, adding adjustable anti-roll bars. The brakes were redesigned to adapt the use of a driver-adjustable brake pressure balance, while the servo-activated braking system was removed. A racing steering rack was used in place of the standard power steering unit. Pneumatic jacks were later added to the cars in the 1980 season to allow for quicker pit stops. Goodyear racing tires were used on all cars.[1] All other non-essential items from the road car were not included, bringing the Procar M1's weight down to 1,020 kilograms (2,200 lb).[8] The performance of the Procar M1s was increased to a top speed of 311 kilometres per hour (193 mph) dependent upon gear ratios,[8] and acceleration from 0–100 km/h (62 mph) in 4.3 seconds. Each Procar M1 cost approximately US $60,000.[1]
470hp in a 1020kg car. Nice

Paul Rosche was the guy at BMW M who designed the Mclaren F1's V12 I believe.
