ive dynoed it a few times on drakes dyno the most it made as is was 602hp.. also ya the trap speed of 103mph and wieght of 7800(it wieghs a bit more but i dont know exactly) that run put it at 578...right now i dont have the gate hooked up so im just letting the backpressure open it..
i think i might try and weld it first before i go to the point of replacing the block.
on a good note my pump should be done today..
correct, 64/71/12 with .700 gates. at 75 psi im seeing 27between so that hp turbo is making about 22psi.. i dont think anything is being oversped at thos pressure.. heat stays below 1600 until rpms go above 3500 or so and that is prolly because of backpressure being an issue..
