% Power loss?

Anyone know the % power loss from the crank to the wheels in a 4th gen camaro/firebird?

or

Has anyone had there unmoded 4th gen dyno'd?
If so what year and all?
Also if you know, what is the rated hp from crank for your car (or else I'll just look for it)?

Thanks alot.

Generally it's accepted that it's 15% for a manual 4th gen, and 20% for an automatic 4th Gen.
