I know but close is not 13s mate could ask god wot bhp he as wot a thread haha:)
I'm not going into this topic again the race teams and motor manufactures have there engines on stands and dynos at the crank .no person selling stuff is going to put whp because it's always lower than crank .but it's what's on the road that counts not at the crank .im not taking this off topic again .sorry frankie
If I've missed it apologies but what boost are you running/will you be running Frankie?
301, at the wheels!
edit: a good link here about losses
http://www.max-boost.co.uk/max-boost...ad%20dynos.htm
Converting wheel bhp to flywheel bhp and vice versa
To reflect the fact that % losses are high for low powered cars and vice versa I use the following equations which have been found to correlate well with real world transmission losses.
FWD cars - add 10 bhp to the wheel figure and divide the result by 0.9
324 is my guess
I don't understand why people use a drag loss as a percentage, surely if your car was 300bhp say the drag loss was 30bhp why is it then if you then tuned your car to 600bhp your drag loss wouldnt still be 30bhp and not 60bhp if drag loss was done at a 10 per cent loss
Coast down/drag losses I agree with you, but real transmission losses need to take account of the friction loss between flywheel and clutch under power (for example) also
It's just rough arsed anyway, 301 whp = 346 at the crank according to the rule of thumb from the link above I posted

SOME INTERESTING GUESSES
What is the point of having 300 crank when you only get 220 whp due to the 4wd drive system sapping all the power before it hits the road .this is just an example not real figuires but you get the idea
