TWR DB7
They used an overbored 6.0-litre block, taken to 6.4, with a specially made steel crankshaft and purpose-designed four-valve-per-cylinder heads, their twin camshafts per bank worked by a unique chain drive system. Claimed power was 475bhp at 6000rpm, supported by 470lb ft of torque at 4500rpm.
Power went through a twin-plate AP Racing clutch with a six-speed Borg Warner T56 gearbox behind it. The ’box had an enormously tall top gear, which gave the Walkinshaw V12 an estimated top speed of 182mph at 5300rpm. The chassis was retuned and design boss Ian Callum made detail changes to the exterior. Walkinshaw had driven almost 10,000 miles in it when Steve Cropley was invited to drive it in the autumn of 1996.
