Aha. Well, maybe the right question is "is your entire electrical system passing enough amperage and voltage to take advantage of a faster motor?" Because an ESC can pass enough of both to operate a higher draw motor but still not give you all of the performance you've paid for.

You're a bright guy and it's obvious you give this stuff some thought, so...if you think of electricity like water, then the bigger the pipe the more amperage (water volume) you can pass through it. Faster motors require more amperage- without it they just won't perform any better than a low amp draw motor. If I turn my amp limiter down to 20 amps or less, the robust motors just don't pop any better than ones right out of the box. Same thing holds true on a dyno- if you use a lower amperage power supply, the numbers just aren't there. Something to think about, anyway.
