Re: E85 gas

>the higher octane of E85 translates into more compression,   I'd like to know how, since changing fuels won't physically change any of the variables (stroke, cylinder volume) that determines the compression ratio.   With the supposedly higher octane rating of the E85, you'll be able to build a motor with a higher compression ratio than you could running on pump gas, but it won't change what you already have.   Randy
