my dad and i were talking last night, and we were talking about the fuel i run while auto-xing, while at the track, and while i'm daily driving. i said from my experience, my car seems to run fine while on 91-93 octane as i just have a stock b16a. i thought my car may run better on 100+ octane although i've never tried race fuel simply because its not the easiest to get. now, he was telling me about his triumph motorcycles that he's had in the past. their compression was similar to that of a b16a (around 10.4:1) and he said with 100+ octane the bike's engine would make more noise, seem to get hotter, and the tailpipes would glow from the increased heat. now, obviously when there is a more efficient burn, an engine will make more power and thus create more heat, right? now i'm wondering if this increased heat would have an adverse affect on engine life, etc. meaning, the hotter and more power a motor makes, the shorter its engine life simply because its working harder and there is more stress on the internals of the motor.

just wondering what everyone elses experiences are with higher octane, and would like to know if my reasoning is simply incorrect.
