Air conditioner robs power?

I was driving in my car the other day. I had 4 passengers in the car and had the AC on. I wanted to show off the car's power to them and went for it. But it felt much slower than I am use to. My passengers thought it was fast, but I know the car is much faster. Is this normal? Does the AC really rob that much power? Could it also be the fact that I had a full crew in the car? I drove the car the next day, just me and I didn't have the AC on. The car felt quick as heck!

AC robs ~25whp. There is a really good thread with dyno info by Shiv on here. Do a search.

well the four people in the car will make it noticably slower, but i have heard that the AC does rob a good amount of power, ive even heard double digit HP numbers, but i dont know if it is really that much

4 people alone will kill it. 4 people and A/C will do it even worse.

I've always heard at WOT the A/C compressor will shut off for the moment.

I guess that is why I am quicker in the winter. Intake air is cooler, windows rolled up and AWD!

This is like asking if bears **** in the woods. Come on, how can you not know A/C rapes you of power? I've known that since I was 16 and have avoided using A/C for that very reason ever since (as long as possible). It also measurably reduces gas mileage.

I knew it robs power I just didn't know it would be that noticeable. I am glad no Mustangs or STi's were next to me.
