the biggest issue from that stand point is that you use more of it (20% more from what I heard) so your fuel mileage drops in the name of performance.
You would be very lucky if you only used 20% more. Most guys up here use at least 30%, and as high as 40% more. Even tuned for "economy".
Imagine getting only 120 miles/tank no matter how nice you drive!
E85 here is about the same price as reg 85 octane. It pretty much stays that way throughout the year. Great performance gas, but horrible for a daily. You can make some really crazy power on it though.
Kesi you said a guy was running 18psi on 11:1 VE? on 92-93 oct? That is just silly. I have run as high as 24psi on 91 oct with 8.5:1, but I was told that amount isn't safe. So I keep it at 19 and under on 91 octane.
