EXACTLY. Or more boost, in the case of super/turbo-charging. Same principle.
I would be amazed if anyone could drive around and detect the difference in performance from premium fuel in a carburated, low compression, antique engine like the one under debate. Higher octane fuel only
enables higher engine performance. It does NOT
create it.
That being said, I completely understand running premium in a higher performance or luxury cars. The ECU can detect knock (if present) and dramatically cut the power by pulling the spark timing. My turbo eclipse used to shut me down all the time, major buzz kill. But then again it probably kept me from blasting holes in the pistons, too. (it was heavily budget modded for performance)
