Not sure about the heat of running 100 octane.

Many do run race gas for the track..I think that'* about 100 or 105 octane. So you should be ok. Willwren frequently ups his rating with an additive and careful calculations.

Is there any particular reason you are looking to run 100?

I'm assuming you're talking about 100 octane unleaded gasoline?

It won't hurt anything. High octane gas doesn't burn "hotter," it just has more knock resistance.

For God'* sake, don't run leaded gas or 100LL avgas through it.

Higher octane will have absolutely no benefit to you unless you have a smaller pulley and a little bit of KR.

Moving to Performance and Brainstorming. Please keep this section for Mechanical Problems ONLY.

And don't trust your source.

Look at the fuel data PERSONALLY.

Its pointless without mods. If you have a 3.3 pulley laying around and wanna try it I suppose you can throw some 100 UNLEADED octane gas in there and run the pulley for the tank.
