it takes 1 HP to lift 1lb 500' in one sec...
or 1HP to lift 500lb 1' in one sec...
use a belt reduction to get to a usable RPM for the test.

i know the best methods, but don`t have such luxury at home like
calibrated generator or motor with digital drive : )

can you be more specific on this - how can i lift the weight at
3000rpm? lift to where - right in the sky? % )
P=M*2*PI*rpm/60, so M=P*60/(2*PI*rpm). i can measure true electric
power, but i don`t know the efficiency of the motor.
maybe you can give a couple of urls?
Let the bass kick! =:-D
