How do Torque and HP differ?

67Dart273 said
Horsepower is merely a mathematical computation derived FROM torque. Google the number "5252" This number links torque and HP. Dynomometers do NOT measure HP. They compute HP They measure, amoung other things such as instruments for air and temp conditions, engine temp, etc etc........

but the BASICS of a dyno for engine performance is ONLY TWO FACTORS:

torque, and RPM. Period.

HP = Torque x RPM ÷ 5252

Thanks,

This article posted by IQ52 explains in detail what you just said:

Makes sense, torque is produced by the force of the piston acting on the crank from what I gather, the gearing turns that torque into HP at the wheels for different purposes. An 18 Wheeler may have as much torque as a dragster, it moves much slower but can move a lot more weight. A dragster goes much faster but is much lighter.
