Hillclimb Engine Technology – Part 4

Now that we have had a look at the recent history of top-line speed hillclimb engines, lets a little bit of a closer look at the powerplants which should be at the top of the tree in 2012.

We’ll start with the motor that has dominated the podium of British Hillclimb Championships for the best part of the last decade and has taken 3 drivers to their titles, the Nicholson McLaren Engines XB V8.

NME V8

Based on the Cosworth XB and now available in four different capacity versions:

The ‘standard’ Indycar V8 capacity was 2.65 litre and Simon Durling used a non-turbo version at this capacity in 2005.

The ‘stretched’ Indycar V8 capacity is 2.8 litre. Alastair Crawford & Karl Davidson both have GR55s with this lower powered, but more drivable & higher revving configuration.

Basil Pitt Gould GR55C

Baz Pitt used 2.8l NME V8 in his GR55C (thanks to Steve Wilkinson)

 

The ‘standard’ LMP2 V8 capacity is 3.3 litre, Simon Durling (GR37) and the Fleetwoods (GR55) used this configuration in 2003.

The ‘stretched’ LMP2 V8 capacity is 3.5 litre and has been used to win 9 British Hillclimb Championships and 3 British Sprint Championships. This engine was also the basis for the GP Masters race series which featured Nigel Mansell, Emerson Fittipaldi, Rene Arnoux and other F1 greats of years gone by.
