I know some of you were interested in this considering the detonation resistance of 105 octane. You should be awaire though that the like gasoline, different winter blends cause different properties, apparently w/ e85 it's a 70% ethanol 30% gasoline blend. Anyway, check this out for tuning properties, I know it's a subie site but just try and overlook that;

if we can simply control detonation and preignition while running gasoline we can do more with gasoline than ethanol

Yeah, that's if you're buying $4/gallon 100 racing gas. E85 is cheap octane.

I don't know how many times I have to say it, OCTANE CONTROLS DETONATION.

The higher the octane, the less detonation.

Yes, it burns w/ less BTUs per unit, that is why you fatten up the fuel curve to run closer to 10:1 afr w/ e85.
