I had an old coworker who had a fox body Mustang. He liked to say "Horsepower doesn't win [drag] races, torque does."

One day we were out servicing a conveyor drive with a 5hp motor attached to a gear reducer. I pointed out the spec plate on the reducer, it claimed an output of more than a thousand foot-pounds of torque.

"So this thing should be able to beat your Mustang in a race, eh?"

Horsepower is just torque * RPM.

I never understood why people care about torque from an engine when it's going to be connected to a gearbox that can convert the torque to whatever you want anyway. So why is torque a more important spec than power for an engine?
