Most of the pumps now have a disclaimer stating that actual alcohol level in E85 is somewhere between 50% to 85%. So if you want to go down this path, plan on 50% alcohol for compression, and 85% alcohol for consumption unless your vehicle has a way of detecting alcohol content like a new Flexfuel car.

Guys on the LS board are running E85 with 11:1 compression and 10 pounds of boost on twin turbos. 1400 horsepower is not out of the question.
