I haven't heard of E85, but when you convert a motor to run on alcohol (cheapest high octane fuel) you need to do a lot of fuel delivery work because the stoichiometry of burning alcohol makes the air:fuel ratio get cut in half roughly. That's why you have to add big float bowl extensions, much larger jets, bigger fuel pump, etc. When you run a roots blower with alcohol, they usually pin the rotors to their shafts because of the volume of liquid getting pumped through the blower. Maybe this E85 is different. Back when I was a college student studying ecology, I learned that the energy inputs to grow corn then convert it into ethanol, are greater than the energy output of burning the ethanol. But as long as we're paying farmers to NOT grow corn....
