"hahahahaha, I just love it when people think that torque does anything on its own. Do you even know what exactly "torque" is? What "HP" is? The physics/engineering definition of these terms? And what they really mean to performance on the street?"

I do. I can even calculate horsepower if you give me the torque.

People who lord over others with their supposed superiority because they know the technical definition of torque or how to calculate horsepower, are irritating.

Torque: A turning or twisting force
HP=TORQUE * RPM / 5252

There, now you can't look down your nose at anyone.

No more so than people who make blanket statements about how "Torque is what gets the job done" or similar. That's all I was trying to get at. A HP number, by itself, tells you a little about the engine, although not enough because it doesn't say anything about the shape of the torque/HP curves. A torque figure by itself doesn't really tell you anything. For example electric motors typically generate their maximum torque at 0 rpm, when they're generating essentially 0 HP, but HP is the key figure when rating electric motors.

HP, over time, is what gets the job done. The area of the HP curve that you're operating under tells you what kind of performance is possible.

BTW, your formula assumes that torque is expressed in ft-lbs, and the constant of 5252 is missing the units to make the conversion work. From a strictly physics/engineering point of view, you understand :)
