You guys are good. To be fair I was only able to run it to 4700 before boost creep became a real problem. 91 octane Esso was the fuel used so the tuner was very conservative.
Basically we observed 622 tq and 556 HP @ 4500-4700 rpm. What is notable is the shape of the curve and it was just about vertical @ the end of the pull. The next step is extensive chassis dyno work which I will be present for once he has larger wastegates installed. I surmise this engine to make 670-720 HP with ease. I believe the timing was stupid low and every time he added 1 deg 25 HP would show up. I want to say less than 20 was where we ended. Very fun and cool sounding engine. J.Rob
