I guess the higher the number the more powerful the engine, right?
Hi Jucava,
Yes. Power from an engine is measured with an open throttle (that is, maximum throttle setting) and the engine is slowed down with a brake to measure the force it produces at different speeds.
Power is a multiple of the torque (turning force) and the speed it produces this torque.
Imagine pushing a weight up a hill. The force you apply to the ground is equivalent to the torque, but in a straight line, and the speed you manage to push it up hill is equivalent to the revs per minute of the engine.
