You mean "horse power" I presume. Go here: http://auto.howstuffworks.com/question622.htm
the engine produces the horse power
50,000 pounds per hour how much horse power
950 horse power
if it had no engine
as you may know, horses used to be used. One horses power was described as 1 horse power, 2 is two horse power and so on, but as the world progeressed, so did technology and cars have lots of power. Still, things were decribed in horse power. So if youir car has 267 horse power, for example, this means that it would take 267 horses to have that much power that the car has in one car. (Corret me if that is wrong, thank you, hope this helped :)
there is no such thing. it is powered by the engine.
