What is the ultimate wedge ?

The latter I'm afraid. Rolling roads consistently show about 40 bhp less than the TVR power official figures. But look on the bright side, the performance claims are actually pretty accurate so who cares?
Peter Humphries (and a green V8S)
I have a wheel figure of 281bhp, and 310 torque. Idonot have a reliable benchmark for these figures, but richard aldous is whitness to my 400SE trying to jump off the rollers at some horrendous speed.
It was fun to notice though that the needle on the dyno actually went off the scale, so the figures I have were obtained from the digital kit plugged in somewhere !
SEACs and Wild cams - yes I believe that was right. Before my first engine replacement I had a "wild" cam 4.2 engine.
With the bigger capacities (4.6 and 5.0) and different cams better use of the V8 torque is obtained negating the need to rev the engine so much.
But then again if the innards on a wild cam 4.2 engine are all steel, lightened etc then you may have an engine that generates more power (less torque) than a 4.6/5.0 (usually) and requires an appropriate driving style.
Rambling again... in fact I've forgotten the question

Jason,
>I have a wheel figure of 281bhp, and >310 torque.
what have you had done recently? The above must be at the 'fly' wheel but on the Progress Engineering day you only had 154bhp at the road wheels. Doing the conversion like-for-like that means you've got approx 35% more power now than then. My 450SE was 190 (wheels) at Progress on the same day and more recently 255ish (dodgy ECU) at Power Engineering. Seems like you have been spending some dosh...

The car in question is the second demo car - it appears in shedloads of articles, all of which I've got, I've passengered as David spun the wheels in 1st,2nd,3rdand 4th and done 135mph in it. I've driven it for a day and it's in one of Geogano's books. An enthusiast must buy this car and nurture it - it goes like shit off ashovel too!
