Hillclimb Engine Technology – Part 2

Apologies for the unusual order of these posts, it appears as though some gremlins have crept into the system (either that or I need to blame Miss Admin, but that is a dangerous game)!

The second part of our look at the technology of the hillclimb engine sees us moving on from the raw power of the Pilbeam MP58s & Gould GR37s to a far more nimble approach, with resulted in much higher cornering speeds.

The early-2000s

When Gould superseded the GR37 with the new GR51 for the Wight family, it was decided that weight and agility would overcome the benefit of the big power V8s. For this reason the tiny, jewel-like Cosworth KF V6 was chosen for the new car. Originally conceived for use in the ultra high-tech Opel Calibras in the DTM championship of the mid-90s, Gould saw something special in this lovely little engine, despite the fact that it cannot be used as a structural component. It is effectively three-quarters of an HB V8, so despite only weighing 85kg it produces over 450bhp!

Combined with the lightweight GR51, the spectacular commitment of Graeme Wight Jnr and the new generation of radial tyres from Avon this combination wiped the floor with the competition in 2001 & 2002, following a learning year (on crossplies) in 2000.
