A guy I work with who seems to be knowledgable on engines told me I should try running Shell's racing fuel in my Kinetic which would give it more power going up hills. I tend to think this is BS. Higher octane fuel just burns slower which reduces engine knock.
I *think* the octane rating of Shell's racing fuel is 104. Which may vary region to region. Just like 91 is the highest you can get in some metro areas, where around here 93 is high octane. Maybe 100 octane in metro areas if even available.
I do know if an car has an engine management system and the engine knocks, the computer will retard the timing. So yeah I could see how running 93 octane versus 87 octane in a BMW would give you more power.
But running 104 octane in a moped with an 8:1 C/R with fixed timing? I don't see how it could make any more power.
I may have to mix up a gallon just for shits and giggles to see if there is anything to it.
