You wanna run the lowest octane possible without knocking to make the most power possibleIf you're pushing the limits of knock, use the highest octane you can get. Detonation is engine death, btw. I'd be setting a stock engine to stock specs.

The specific energy of gasoline is not affected by its octane rating. Octane is essentially 'knock resistance'; the higher the number, the more your fuel will resist detonation before it's party time.You wanna run the lowest octane possible without knocking to make the most power possible
It depends on what they're using to get a higher octane. If they're using ethanol to raise the octane, you don't lose any significant horsepower. I don't know what effect MTBE or BEX have on the power output, but I know back in the day guys were dynoing engines with 87 octane and 91 octane and could see a difference.The specific energy of gasoline is not affected by its octane rating.
