Dyno Guesses & Bench Racing Forum - BPU Supra Hp/Tq Numbers????

Was wondering if anyone could guess how much power my homies BPU 2JZ Supra would put down. Hes on stock TT, exhaust, downpipe, 21 lbs boost, & 100 oct..

...416rwhp perhaps? Not really familiar with the engine, though I'm sure the people on supraforums (probably where this question belongs anyway) could tell you. Also, remove the "probably" from that last phrase if you want the truth.
