my tuner told me e85 is really no benefit unless your making around 700hp.
I will add to that. It runs WAY MORE consistent pass after pass. Especially with a heat soaked Eaton.105 octane, runs cooler, able to bump timing, and CHEAP.....don't see where there's not a benefit.
What's funny is that HPP didn't even use or mess with E85 until I had switched and a buddy of mine that I helped switch went over there to dyno.Just ask the guys at HPP in dallas. I am sure they can tell you all about the increase in numbers and performance gains for the corn oil...lol
I was telling Manny about it and he said he never really messed with it. Now he is switching a lot of cars over.
