Well folks I think I have a solution for you guys wanting to run on E85.
Is there anyone wanting to try out an E85 program for their vehicle (with no promises)?
In the December issue of 5.0 mustang magazine thay made 668HP on a supercharged stang.
Here's a video of a non flex fuel truck that did it anyway for over 100,000 miles:http://www.youtube.com/watch?v=HuOs1yap8mU
As long as your fuel lines and rails are steel and not alumnium E85 should work for you. The only way you will screw anything up is if your injectors and or pump are already at full capacity.
