How does cid make power?

But also, torque is meaningless. It's a force. It's measured instantaneously. It doesn't have anything to do with how well the engine can accelerate - that's why the HP measure exists. Without it, we cannot relate to what happens 'per unit time', meaning we can't figure out how the engine will accelerate, how it will propel, or how much weight it can move in a given amount of time.

It's why tractors are rated by horsepower and not torque, despite needing torque to 'pull stumps' and such. Only having a 105 ft-lbs measure wouldn't tell me much about what I can do with an engine. But tell me 5, 10, 40 horse and I know how much it can 'do' in a unit of time.
