The car has previously run 360bhp on the dyno but with my recent mods will see approx 420bhp with my new throttle body injection setup, 1000cc fuel injectors and GT ball bearing turbo.

I have tried to make the car as light as possible and everything on my car is either carbon or alloy so at the maximum it will be 600kg.

E.g. My 13" wheels are lightweight billet and weigh just over 3kg each, they cost me over £300 each though. I can imagine a regular 17" wheel being nearer to 15kg each.

I also have a Lightweight chassis option and bodywork which also keep weight down (approx 20kg lighter). Doesn't sound alot but savings here and there soon add up. Other weight savings include:

7" Quaiffe diff (10 - 15kg saving over 7.5 " cossy diff), Alloy bell housing (5kg), Quaiffe alloy gearbox casing for sequential box (5kg) etc. etc.


Westfields are lighter than Dax rushes, Westfield quote in the 400's kg for their bike engined lightweight kits

Some of the run of the mill Westfield racecars with windscreens are sub 600kg's

420bhp / 600kg at a push = 0.7 bhp/tonne

x 1000 = 700bhp per tonne
