or if you know your HP at a given RPM you can calculate torque using
Torque = HP * 5252
------------
RPM
In Cronic Burn's Case....he gets his max torque at about 6100 RPMs...I plugged in quite a few times to get the numbers right....
156.9*5252 = 824038.8
824038.8/6100 = 135.08 that's only .42 shy of 135.5 and now you know your torque curve.
