Octane doesn't equal power, a higher octane rating means the fuel is less likely to ignite. The reason race cars use gas with a higher octane rating is typically to prevent detonation in the cylinders. this is usually caused by very high compression ratios, very advanced timing, or a combination of both.


As a sidenote, Bikecop, did the kit include all the replacements for the rubber parts in your fuel delivery system? The stock rubber parts cannot handle the E-85 long term. I'd definitely keep an eye on them for signs of degradation if they haven't been replaced.
