[QUOTE="Swervedriver, post: 14049582, member: 12324"] Over pump gas a 100rwhp gain is possible with an aftermarket power adder. In fact, E85 will allow a combination that can't reliably even be run with pump gas (flat top pistons, >10:1 static compression, and >20psi boost with >15° timing advance) For an Eaton I don't think you'd see a 100rwhp gain but it could be possible. Compared to race gas with a >100 octane, there won't be much gain with E85, but you can get away with higher IAT2 due to the impressive cooling nature of E85, as well as the 30% increase in volume. However, there is still a threshold that you don't want to go over. Hot spots can cause pre-ignition without audible detonation in an E85 compression event. You'll just go from running hard to total loss of compression due to torched piston and/or head. It's unclear to me if a J&S knock sensor/guard can detect pre-ignition in an E85 compression event and I can't afford to fund the research to find out... [/QUOTE]
