ok yes this is yet another post about the infamous ac/ delete question,i know what belt size to run but my question is related to a post that i found during a search,from Shifted,ive heard arguments that deleting the a/c or a/c pulley,gives you small h.p. gains and then what Shifted said makes sense, as far as the a/c pulley spinning freely until the a/c is turned,engaging the clutch and taxing the motor,so does running a smaller belt on a stock pulley setup give h.p. gains or not,any help?thanks

Not worth the time or work to remove the a/c.

thanks i appreciate someone gettin back to me

Well in regards to what shifted said, that is not totally true. If you are spinning a pulley it is asboring some power (might be very minor, but it is power. Comes down to how much work you are will to do for power. From that last post people were stating too much work for the small amount. Well not sure about most of you but I'm not rich (if we were we probably would not be on this site), so any power I can get for free, or really cheap works for me. Also people spend so much time taking things out of there car to be faster, this is the same concept.

ur gonna pick up what a possible 1.5hp? I mean if ur really building a drag car or something do it but for the time it takes to pull the ac off find a belt and all that id rather spend that time port and polishing a cylnder head but everyones entitled to their own opinion im just giving my input on the idea

What if you do not have to pull the AC off? What if you have a ported head. If you can do it without pulling the ac off, and just put a shortet belt on, then it is not that big of a deal to spend 10 minutes to put a belt on before going to the track. Heck I spend longer preping my car for the track , or even a show.

Damn though, everything adds up you know? It's not like I'm going to get a header instead of an intake and just finish right there. Unless he lives down here in Houston where it's summer all year round with high ass humidity, then an A/C delete wouldn't be that big of loss for him. But I would remove my A/C and get a shorter belt in a heart-beat if I didn't live here. It's not always about the major mods you know. The little things add up and they are the ones who put you ahead by a car length. I agree with John; even if you don't remove your A/C you can always just change the belt real quick whenever you want. And imo, I think removing the A/C will make a bigger impact on his 1/4 time then on his dyno numbers. It will free up usable hp throughout his whole rpm range.

thanks for all the feedback,true every little bit counts but after thinkin about it ill go with the other mods,intake mani,afpr,turbo,etc; etc; ive got a vert so i dont really need a/c but i also have a 3yr old girl and girls are picky ,lol and with a vert you cant always have the top down when its 90 deg. out with the sun beamin down on a little kid so even though id like to get rid of the a/c and gain a little extra h.p. ill keep it for now and gain the extra h.p. elsewhere thanks

Sorry if I am thread-jacking, but I live in upstate NY where A/C isn't always necessary, but defrost is a must. I noticed the A/C comes on when the defrost is turned on, so would removing the A/C affect the capabilities of the defrost mode? I don't care about the horsepower, but my A/C clutch is squealing and since I never use A/C, I would rather remove it than replace it. Thanks.

Just remove it, plus the small hp gain you will get (1 hp) extra weight will be removed too.


I want to share something with you - the three sentences that will get you through life. Number one, 'cover for me', Number two, 'oh, good idea, boss', Number three, 'it was like that when I got here.'

Well I think it is worth it because it is low cost and fairly easy. You are removing 33 or so pounds of weight, and removing a little weight from the rotating assembly can never hurt. It a helper mod in my opinion...every little bit helps.

The car WILL take a little longer to defrost in very cold weather, but it is not that bad. Maybe another minute or two.

i had read somewhere on this site about taking the two wire plug that goes into the a/c compressor out to bypass the a/c which i did now this may be a dumb question considering ive never really stood and watched my belt run on the pulleys,but isnt the a/c pulley supposed to spin freely even after taking the plug out of it? because it looks like it is not turning,.when i turn the heat on with defrost the a/c light still comes on i just dont want my belt to snap while driving

Not worth it IMO the time and effort spent to remove the AC system would be better spent elsewhere for larger gains. If you decide to remove AC for extra power it should be the last thing that goes, you need to remove a lot more than 33lbs for a significant performance gain, but every little bit does count.

Many people argue the idea that they don't need the ac or don't use it all that much, but you really need to think about it very hard before you decide to remove it, you may regret it a lot in the end.
