another car's dyno on pump gas? Every car is different, and different conditions. Gas quality can very from area to area. With race gas, you have greater envelope of safety than you do with pump gas. My friend did 35 psi on C16 race gas with his dyno pulls on his Supra. With pump gas you have a lot narrower envelope. Not many people are going to risk there engine to show how good their car can do with pump gas. It is not worth the $$$ of an engine. For the Z32, it is safe to say 500HP is the limits of pump gas on average. Sure you can get away with more. But the risk is much higher. On a cold day you might get a way with 550HP. On a hot day the same tune will blow it. It is like Russian roulette. I talked to Jim Wolf, he has blown his share of engines exploring the threshold of pump gas. He can afford to do that. Most of us cant'.
