BHP @ Wheels - Flywheel

[BaldGuy]

I know there are some seriously clever people on here that can help me....

I have a small project on the go that will yield me 270bhp @ the wheels from past fitment analysis from other customers.

So i've always known for instance my 911 is 320bhp, now where is that @? The flywheel? if so what roughly would it be at the wheels?

And on the flip side.... 270bhp at the wheels whats that in real terms as above.. i.e at the flywheel...

Sorry if this is confusing, i'm confusing myself here....

All help grateful

Cheers Greg

If it's a manual gearbox car expect about 15% loss if it's auto expect about 18%, so 320 bhp at the flywheel should yield about 272 or 262 at the wheels.
