e85 The Question.....

I think he maybe thinking of the need to run a higher comp. ratio as a suggestion turned mandatory. While you guys are right, I think the suggestion is not only to take advantage of the ability to use a higher compression ratio but also to try and reclaim the loss against the E-85's low BTU return.

I do not remember off the top of my head the BTU numbers of the various petrol fuels vs. the E-85. But there is a power drop in a apple to Apple comparison. This is where they say intro more fuel. This helps balance it a bit more since you need a certain percent more E-85 fuel.

With that said, upping the compression ratio to take advantage of the high octane ability of the fuel can reintroduce lost power and mileage. If a 1 point ratio change upwards gives a return of 3%, then, if a 2 point ratio change upwards gives 6%, you could possibly reclaim lost mileage?

(Did I make sense? Just waking up.)

Anyways, I have also considered this move myself for my Cuda. It's basically a 11-1 aluminum headed 360. Solid cam @ 248 @ .050.
