finally have a friend that did a before and after e85 pull to see the benefits of e85. Granted it’s a ls3 corvette, but it gained 150rwhp going from 93 to pump e85 and according to the flex fuel sensor it was around e70-74 I think. Sbe ls3, cam, exhaust, ysi with stock converter. What’s the most power increase you have seen switching to e85? Bonus points on a vortech mod motor.
