Octane ans rpm
From what I have learned 11.1 is the max compression you can run 100% safe and to the 100% max potential on a street motor with 91 octane.
But certain fuels do not burn properly at certain rpm, that is why there are different blends with race fuels.
My question is, all other factors aside, what is the max rpm that 91 octane can work properly with before it does not burn properly?
