Ac Removal/Horsepower Increase

If the entire AC system is removed, what is the approximate horsepower increase? I guestimated around 50lbs. decrease.......anyone know?

none.

You have to change something to get hp increase.

Lowering the weight on the car will increase the pounds/hp ratio so you will feel as if you gained hp is all.

I just took the AC belt off my 1.0 today and my butt dyno tells me that it has more power. I don't think the weight loss would do much however.

Any parasitic drag on the crank will always increase power. You'll notice a difference if you even just remove the a/c belt. I'd leave it on IMO. A/C is nice to have sometimes.

I have to put mine back on! It is getting HOT here in Sacramento.

I left it off during the winter and spring.

And ditto what geozuki said. Some folks have gone to lighter flywheels and mainshaft pulleys to decrease the drag.

I haven't done that yet so I cannot comment on the problems vs. benefits.

well i took the belt of in january, and didn't notice much....seems likewaste of money i suppose so i prolly won't mess with it. thanks guys

Not exactly regarding horsepower, more towards MPG, wouldn't you need to compare the MPG loss to drag to the MPG loss to running the AC with the windows up if its hot enough outside and youre driving fast?
