From my research you definitely have to be careful of what exactly you are buying and where you are buying the E85. It can vary but 105 octane is attainable from what I've read -- like anything, buyer beware, and you have to do your research. I've seen you can get as low as 95-96 octane and as high as 105. You can also buy in drums if you'd like, which is what my buddy back in South Dakota does with his converted race car. He pays like $2/gallon and gained 3 tenths in his 10 second drag car - no other changes.
