E85 is better in boosted applications. It has a higher overal octane, at the expense of requiring somewhere around 30% more fuel to make the same amount of power. Also, it burns cooler than regular fuel, and its cheaper. So basically its race gas, for E85 prices.

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.

Yeah, but the power gain you're going to get out of this is minimal at best with E85, compared to the effort you'll have to go through just to get the car READY for it.
