Kw's At The Crank

[deano59]

Hi all, I am a little confused as to how many kw's at the crank a car would be if it was running 254rwks, I think I read somewhere that you loose approx 22% through the drive train is this correct.

Thanks

It's really different for each car, but on average 240kw is producing about 196kw at the wheels. If you work that percentage out you should be able to get the figure you want.

I'd say you'd have about 320 at the flywheel if your dyno figure is accurate. At least it gives you a ballpark figure but what use it is to you I really don't know.

What power my car has either at the wheels or the engine is simply zzzzzzz, boring, zzzzzzz. Thing is, it's never enough ay!!

my understanding is that autos lose about 22%, manuals about 17%.

so if you take 2 stock XR6Ts, one auto, one spanish, the spaniard should have a higher rwkW figure.
