Prob not the max, but good considering. My MP T70 with a P-trim exhaust wheel is good for 616/634 at 13psi on a 348" ls1 with stock 853 heads, LPE GT7 cam, and stock ls1 intake thru a 6 speed and 12 bolt.

I believe 1badls1 put down about 550whp @ 10 psi through a slipping tranny w/a 5.3. Hes up to 15psi now and has a th400 so I would think closer to 700whp. I havent had a chance to tune mine so I have no idea. Im hoping 600whp @10 psi.

Parish8 put a stock 5.3 into an old Ford Fairmont that weighed around 3,000lbs and ran a MPT70 with a TH400 and went high 9's@140mph+. Only internal upgrades to the 5.3 were a used Z06 cam and some valvesprings! Hundreds of passes without failure. That turbo is rated at somewhere around 700-750hp flywheel.
