I know that you aren't a big fan ethanol Mark, but you do realize that in an engine like the LS3, LS7, LSA, LS9 or the "new" LT1 running E85 would help to coax a few more ponies out of them ? A perfect example of how E85 can improve a sports car's performance would be the Koenigsegg CCXR. It is a flex-fuel capable supercar and quite a monster making a stout 806hp on gas, but puts out a whopping 1018hp on E85. That is a massive 212hp increase just by filling up at a different pump. Granted the CCXR is twin turbocharged, but higher performance N/A engines do make more power with E85 too. Most of the issues that plague E10 aren't a concern with E85 and corrosion isn't a concern because these vehicles are designed to be compatible with alcohol. Since there is 70-85% alcohol it would take a boatload of water to ruin the fuel and I don't think that phase separation is a problem due to the small amount of gas and/or other chemicals that make up the remaining 15-30% of the fuel.
