what's the highest compression piston i can run on 93 octane pump gas?
My personal street driven builds:
12.6:1 on 92 octane, low 12:1 a/f ratios
12.4:1 on 93 octane, mid 13:1 a/f ratios
12.77:1 on 93 octane, low 12:1 a/f ratios (current)
You can run in the 13s if you really want to. It's all about the tuning.
