David, thanks, I stand reluctantly corrected.

I'm not sure I trust Wickipedia for much, but they define it as flywheel hp, absent losses, since the band brake ("brake" HP) was applied to the crankshaft to measure the torque. I thought the term applied to all HP readings since they all use a form of "brake" to measure torque and arithmetically determine HP from there...

I bet there's a dyno genius out there that can set me straight :-).
