I never meant to imply that people ran the 1/4 mile with the AC on ... anyone with common sense knows better. But since when does going to the dyno have anything to do with the 1/4 mile ... the two are completely sperate beasts! Sure, you can tune your car with the dyno to run better in the 1/4 mile, but the two are still seperate. You go to the dyno to see how much HP/TQ your car has ... you go to the track to see if you can get that HP/TQ to the ground to the best of your ability. What I was getting at was finding out how much the AC saps from the engine. Out of pure curiosity of course

Also, about the AC cutting out at WOT ... this isn't an instant act, it takes time for the car to figure these things out. I would have to say that the AC robs the engine of at least 15hp, maybe more like 20-25hp, but nobody will know unless you try this.
