GR51
When approached to design and build a new car for the Wight family we never knew how successful the car would become. An excellent driver can make all the difference but there is no doubting what a revolutionary car it was.

The GR51 challenged a well-founded approach in speed hill climbing and sprint racing that there is no substitute for horsepower. That is often true but power to weight is what really matters and the Cosworth 2.8 V6 KF engine prepared by Geoff Richardson Engines is, for its size, a remarkable engine. Built around this small, light, but powerful engine the GR51 chassis was an amalgamation of expertise and with a noticeable power deficit to many 5.0 litre engines the car was a real lightweight exercise. The chassis was developed in conjunction with Ralt, although the Gould version of the chassis had many hill climbing specific features, including all the aerodynamic aids. Without any existing gearboxes in manufacture that could do the lightweight car justice a Arrows F1 gearbox was modified by Gould Engineering and mated to the KF engine. Light and aerodynamically sculpted for the diffuser, yet very strong this proved a winning package.
