Look forward to seeing your results.

Believe it or not, I made 750+whp on pump gas beforei push coolant. Our pump gas is not e85 but it is much more knock resistant than your 93pump gas. We upped the boost on 45psi and we did not even try to push the timing, we left it before even knocked. If you like pm me to send you the dyno

45psi on any pump gas is asking for trouble. The headgasket expired . An engine is not going to be happy under those conditions.

Its a good idea to run the proper compression/octane for the power you are going for IMO. Good fuel is cheap insurance if you are going to run it hard.

Yea man i get it. Probably this time we will lower the boost and try turning the ignition a few degrees. If it makes 700whp I will be happy. I know it is doable, since Aaron from ER made 687whp at 29psi and with a very similar build with mine

There are limits with octane and cylinder pressure that need to be respected IMO.
With ethanol and race fuel being so inexpensive , I just don't see the point in breaking something on pump gas to hit a number.

Thats an expensive trophy.
