Engine torque
So I had posted a while back about why the older IH cubs had more "umph" than the newer ones yet have less HP, and everyone said it was torque.
On Tractor gearbox website it lists torque for the newer cubs but not the older ones. So I tried running the engine HP and RPM through a torque calculator but the numbers don't seem to add up, even for the newer cubs. For example it lists a 15HP at 3600RPM as having only 21.9ft lbs of torque, but the specs for that particular engine show it as having 25.3ft lbs.
So my question is, what's the best way to calculate engine torque? What kind of torque do the older IH Cub engines have, since they are not listed in the specs? Am I totally missing something here?
