Check my math, it wasn't my best subject.
Calculating torque and hp
If we know an engine's torque in foot pounds, and the rpm at which it was measured, we can calculate hp.
It would seem if we already know engine hp and the rpm at which it was measured, we can calculate torque in foot pounds.
HP Calculation
RPM x Torque (ft/lb)
----------------------- = HP
5252
Torque Calculation
HP
---- X 5252 = Torque (ft/lb)
RPM
I used hypothetical to test hp formula (7000rpm x 66 ft/lb torque divided by 5252)
Answer = 87.96 hp
torque hypothetical (87.96 hp divided by 7000 rpm x 5252) Answer = 65.99 ft/lb torque
(Where are the engine rpm's shown on your Dyno graphs?)
