If you are in touch with your vehicle's behavior at all you will notice lack of power and it is definitely present. I know when I feel sluggish I look down and sure enough the a/c is on. I wouldn't notice if it were only 2-3 hp. Searching on the net I have seen figures 5-15. I think our cars are on the high side or I am just very sensitive to noticing power change.
