93 octane gas only?

I'm sorry if I rain on anyone's parade -- but the lower the octane you can get away with (without pinging), the more power.

No rain here... the science just doesn't back you up on this. It seems you have a misconception on what "volatile" means. It is not a measurement of energy content.

You wrote "87 octane has more potential horsepower than 93 (or higher) octane." "The lower the octane number the more volatile the gasoline -- by comparison, the higher the octane number the less volatile (combustible) the gasoline."

You are asserting that the more volatile gas is, the more horsepower it can produce. That's simply incorrect. They have different burn characteristics, but the same amount of energy. Energy produces horsepower, not volatility.
