87 octane burns quicker and hotter there for giving you more HP.
So the lowest octane you can get away with, without damaging your engine, actually makes more hp? I don't get why people run 101 or 110 octane in their car? I'm assuming it depends on the engine, how big the whole fuel set up is, etc.
I run 93 in both my bike and my 5.0. What is the lowest octane I can get away with in my bike?
I was talking with Vince(Show5oh) about octane in motorcycles. He runs 89 I believe, maybe even 87. I remember him saying that it makes him look cheap because he buys the cheaper gas, but his bike is actually faster and runs better. I understood what he said, but I have always just thought that 93 was the best, no matter what. So I guess I was wrong.
Offtopic- DogBoneR1 are you going on the March 5th ride?
