Hillclimb Engine Technology – Part 6

The latest stop off on our tour of the top hillclimb engines will focus on the powerplant that dominated the early noughties in terms of results and th emid-noughties in terms of numbers. Small, light, reasonably powerful and fairly plentiful, the Cosworth KF engine saw the sound of thumping V8s replaced by howling V6′s on the hills.

At one stage there were KF V6s everywhere in the hillclimb paddocks, but they have become less & less popular in recent seasons. There have been two specs of KF used on the hills, standard non-air valve spec with about 450bhp and an uprated non-air valve spec (complete with cams designed by Warby, and drawn with a ruler!) which saw over 500bhp when used in the Warburton/Haimes Dallara V6.

Briefly, following Gould’s lead, a couple of other hillclimb manufacturers created chassis based around the little V6 and there were a dozen or so of the engines around the paddocks.

Pilbeam built early versions of their MP88 chassis with KF engines for Roger & Scott Moran & John Leinster using a Hewland FTRS 6-speed sequential gearbox and a very complex aero package.

Force Racing Cars built their first automotive engined car using an ex. Roger Moran KF and an FTRS ‘box. The chassis, which was basically a Force PC tub with carbon extensions at the rear, was built for Tony Eyles primarily for sprinting. Eyle’s claimed the 2005 British Sprint Championship with the car.
