Seriously tho. Too many variables to make a prediction.
Generally tho.800-1000+ is the norm for twins and anything over a 6.0 motor

Really all depends on what turbos, compression, fuel, meth kit? A lot of variables. My 383 put down 660 but it had no meth kit on pump gas. The turbos were old cheap turbos that I dont even know the specs of and the kit was a POS. I switched it out for a single billet wheel 7675 hoping for close to 800 rwhp.
