20-25% drivetrain loss in FWD is the norm. Consider 20% loss for a new performance built trans (from what my builder told me). 25% with a stock OEM trans with moderate mileage.

You took the wheel numbers and added ~20% to get those numbers? Not trying to be a smartass, Im just curious if you really dyno'd your engine.
Yes. Any more than 20% would yeild even higher nubers at the crank. Yes, I did dyno my car. It wasn't cheap either. There are pictures on here somewhere. Just do a search, you'll find em'.

25%?!? I dunno. Even though these engines are underrated, 285 hp and 350 tq would be pushing it.
