sorry for butting in here, but remember as well that if you run e85 or e100 or any mix of that with gasoline (as in a flexfuel vehicle) you must have the appropriate fuel delivery components such as:
stainless steel tank or teflon coated fuel tank, stainless steel fuel hard lines, teflon coated rubber efi hose and a compatible fuel pump/injectors capable of flowing more fuel and combating e85/e100's corrosive nature.
dont forget that if you plan to run both at seperate times or a mix of the two, your tune must change if you run full e85 or full gasoline, or a mix.
e85 is great under boost, as its octane rating sits around 100ish, some say less some say more, i go by testing ethanol from my local e85 station. (god i love having freinds in the lab), and its cheaper than regular gas.
e100 is even more appropriate for boost, as the octane rating has been said to test as high as 120, but dont quote me on that.
anyway, just some pointers, good luck with it!
