torque is an instantaneous force
power is a measure of the rate of work (force over a distance) over time, time-distance in the case of rotary motion is rev/min
1 HP = moving 550 lbs 1 foot in 1 sec or work/time
T = HP x 5252/rpm
5252 = 550 ft lb/sec x 60 sec/min / 2 Pi
unit check: ft lb/sec x sec/min x 1 rev x 1/rev/min = ft lb cancelling units...or torque...
it's best not looking at these like seperate variables, they are measures of different things, but related...
only 2 things effect engine torque, displacement, and pressure (ratio and boost, mean effective)
T = (V/p)/4Pi, that simple
T = 2 Pi P n
2 Pi n = rottational speed w...
so T = w P
