A big misconception with race gas is that the higher the octane the more power you'll have. Which isn't true. The only reason to run a higher octane gas is if your engine is knocking or you have a higher than stock compression. I'm sure somebody with a lot more knowledge in this matter will chime in.
Exactly. Here's an article that may shed some light on the subject.
http://en.wikipedia.org/wiki/Octane_rating
"A common misconception is that power output or fuel mileage can be improved by burning higher octane fuel than specified by the engine manufacturer. The power output of an engine depends in part on the energy density of its fuel, but similar fuels with different octane ratings have similar density. Because switching to a higher octane fuel does not add more hydrocarbon content or oxygen, the engine cannot produce more power."
Unless you're running 15:1 or higher compression with extremely advanced ignition timing, you would never need anything over 110 race gas. It does not provide "more power."
