have any of you tried using a Gallon or two of e85 mixed with 91 octane to try and bump up octane? not that many e85 stations around to switch to full e85.
thanks for all the info. looking for a little more power to keep up with a couple of my buddies with the new 5.0. they both have stage 2 whipple's.
If they're 6R auto cars I doubt you'll have much luck, but you'd better be a helluva wheel man if you try.That's a tall order...Stage 2 whipple coyotes make 700-750 to the tire and weigh a couple hundred lbs less than a gt500.
Def going to need a blower upgrade and some.
