I got into this argument with one of my firends. I'm interested in knowing what the real answer is.

We also go into the argument that if it mathmatically possiable to figure out Torque if you know the RPM and HP. I disagree that it is mathmatically possiable. Why is it that someone with one kind of motor setup have more torque then another person with a different motor setup but they both have the exact same HP?

It is possible to compute torque if you know the HP and the RPM at which that HP is produced. This is because horsepower is a function of torque at a specific rpm. An engine dyno measures the torque that the engine puts out at a certain rpm and then the hp is computed from that torque measurement.

The formula is:

HP = (torque X RPM) / 5252

or

Torque = (HP x 5252) / RPM
