However, there are downsides - as the weather chances, E85 is sometimes reduced to E70 due to lack of enough ethanol, and this can cause detonation if either a proper tune isnt run, or you simply dont go looking for a place that ALWAYS sells E85. Also, another obvious downside...you're burning a little over 30% more fuel lol. The only benefit an E85-tuned N/A 370 would get, is from retarding the timing to a higher octane to squeeze out a few more horsepower. Not worth the effort in the end, IMHO. However, in a BOOSTED application (like the GT-R, obviously), you'll be able to run a higher amount of boost without detonation. Thats why boosted applications gain so much power on a properly tuned E85 setup.

^ pretty much nailed it. I ran my s2k on e85 for a while, and the Subaru guys love to switch to the stuff for power builds. It let's you run a race gas tune on the street.

I have always advanced the timing when running higher octane fuel (compared to 93 or whatever). Both in N/A and with power adders. I thought that was the main reason so you could make more power without detonation.
