It was in the link I posted. Torque may be present with a non-rotating motor, but power is 0, because the rotation in equation is 0. When it starts moving/rotating, power "happens"
This discussion started from driveability and aggressiveness of certain engine types. Torg/power curves are done at full throttle on dyno and they tell the maximum capacity of the engine. However, outside racing we hardly ever push gas pedal down and hold it there for even tens of seconds. How a car or a bike feels at normal everyday cruising, comes very much from max torq/power at low rpm and throttle response. Throttle response is determined by valve timing, injection and ignition control, intake/exhaust port control etc. modern "black box"programming (and gearbox programming if automatic) Consumer market cars hardly ever use full potential of the mechanics powerwise, because they must fulfill also emission controls! Chip tuning is popular now, even among truckers and farmers!
