750 Formula Championship - A brief outline
A true two-seater sports-racing car, although passenger space is very small! Most cars have been individually designed and built by enthusiasts over the years to comply with the chassis regulations; many cars are available second-hand. Essentially the cars are lightweight, space-frame with aluminium panels and fibreglass bodywork.
Engine (section 5.7)
Cars must use either the Reliant 850cc engine or, newly introduced, the Fiat 1108cc ‘FIRE’ engine. Tuning on the Reliant is quite extensive, whilst the Fiat engine is basically standard. With both engines induction is restricted to one carburettor choke; exhaust system is free. Power outputs are in the region of 65 - 70 bhp, but the cars weigh about 350kgs. Average lap speed is 85-95mph.
