Sorry, just saw this, I'm not talking about stock/standard cars - we're talking about modified - and I'm sure you know how much power the turbo Vipers etc... are putting out (or do you not know?)
Isn't it supposed to be cars you acutally own? I've got 140bhp at the fly wheel in my ex-Brian Rickets Motorsport, TSR headed, 4 brached Mk1 Golf GTI 8v. Weight, well whatever a Mk1 Campaign weighs. It'll hopefully be making a bit more soon, I'll be bolting my roaring 40's on
