We had another .5 AFR+ to go, 1 or 2 more psi, a couple degrees more timig and 1k RPM more that we could have spun it up to. It was 7:30PM at night so we quit. We probably could have gotten past 500rwhp and we think we could have done it safely on pump gas. The car is daily driven, and the knock sensor hasn't shown any signs of knocking on 92 at full boost. I am convinced that there is much more in it, but the car barely gets traction in 3rd gear with 275s so pushing for 500 rwhp is impractical except for bragging rights, which I don't care about. The above printout wasnt the last run, but the final sheet wasn't much different (I don't have it on this laptop)
This dyno sheet shows my new GTX3076R plot over my old GT2871R plot; same car same dyno.
