Chevron B12 Repco V8 - ex John Woolfe
is this unique 1968 Chevron B12 sports prototype
Together with his business partner Arnold Burton he ordered a rolling chassis from Chevron. The B12 was designed for a Repco F1 engine. The idea was to race the car at national events as well as the 24 hours of Le Mans and international competitions.
The car made its debut on 6th May 1968 at Silverstone showing its potential with a victory and breaking the outright lap record. The car beat competitors like the Lola T70 Mk III GT of Sidney Taylor. Following were a string of wins in British club races. At Watkins Glen John Woolfe was supported by the great sports car racer David Piper. Together they reached a respectable 10th place in qualification. Before that event John Woolfe and Derek Bennett achieved a solid 8th place at the Anderstorp circuit in Sweden.
The car was also entered at Le Mans in 1968. Unfortunately, the team had to retire after 2 hours due to a blown head gasket. According to John Woolfe’s co-driver Digby Martland the car was very quick beating the Ford GT40 on several occasions.
In 1970 the car was raced by Alistair Cowin at the RAC Thruxton event and the 1000 km of Brands Hatch.
In 1972 the car was taken to Nürburgring Interserie race by Detlef Vanselow to its last race.
In 2007 the car was bought by its current owner and restored to concourse condition. During the restoration process, an original Repco F1 engine was acquired in America to complete the car to its former glory. The restoration process is documented throughout with pictures.
