Removing your A/C & P/S belt= More horsepower?

[0r1landoDSM]

is there an actual dyno testing on this on how much HP doing this will free up? is it even worth doing this?

There was a small little study UTI students did that showed on average it made less than 1 HP difference. Of course the AC was not on at the time.

I'd look into underdrive pulleys before I'd worry about that belt.

It might be worth 1 or 2 HP. Not enough to notice...
It's not worth doing if you're only doing it for a HP gain.

 

[GRAVEDIGGER]

I would be willing to bet that the difference would barely be measurable, if at all, and doing it for a power increase would be futile.

Knowing that im considering putting the ac back in my car it was hot last summer.

awesome! thanks guys!

removing the a.c will only give you a small weight reduction and having the a.c in your car wont decrease HP unless you have the a.c on and the a.c clutch kicks in

That depends on what you consider 'small'. The entire A/C system weighs in the 30-50 lb. range. I'd consider removing that to b a pretty good weight savings. Not to mention it removes one more belt and tensioner, allows better airflow to the radiator, and makes installing/uninstalling the engine much easier and quicker.

While removing the a/c won't free up much in the way of horsepower there are other benifits. The entire a/c system weighs over 60 lbs (1g)(which is pretty significant in my book) and without having the condenser in front of the radiator it can aid in cooling, especially with a FMIC. Mines been gone for years and I've never missed it. To each their own though.

Yes and yes again. You guys are absolutely right. There are more benifits besides just freeing up power, as long as you can go without the comfort of a/c.

Removing the a/c compressor also frees up room for alternater relocation to get it away from the heat of your turbo and manifold. I'm getting rid of mine for that reason, along with the weight reduction and less clutter. If you're just removing the belt, but not the whole system, then hp gains aren't going to be noticeable

It will have less stress on the crank. So it will be freer to move. Maybe rev a little faster.

If you live in the south like here texas i would keep it temps over here get more than 100 + summers

 

[Urban Survival]

Yup I get rid of my a/c systems for the reasons of air flow, weight reduction, and less rotating mass.

 

[DSM1G90]

I'd keep the stock pulley due to it being the harmonic balancer pulley that you need.

AC I don't have, but love my power steering. Done with power cranking the steering wheel.

I do live in Texas and its been over 100* all week, like I said, I've never missed it. To each their own.

 

[afoster98GSX]

My idea of ac is 2 windows down and 75 on the speedo.

Agreed!, I thought my ac removal was well worth it for all of those above reasons

Live in Austin, Texas. Haven't had my A/C for 3 years now, and in times like these (a week of straight smashing high temp records all around 103'F for JUNE aka SPRING) i some times think to myself, "why did i do this?" but other than that i never tend to use the A/C even if i have it available!
I like my A/C being gone, im in the process of removing ALL the other part now; condenser, ect. (took the a/c compressor off years ago!)

Oh man, and in El Paso, i saw on the new this week it was getting WELL in the 100's, the high for Laredo the other day was 108'F!!!

Heck yeah, that's how we roll out here Shawn! We keep it hot

 

[92AWDHX40]

Mine never worked anyway so it got yanked out its not a daily driver i dont miss it.

 

[bullet99]

I rarely use my A/C even with my DD. I live in SW Florida.

Yes sir!!
(not to jump off subject but..) On the news last week i was watching people in Chicago on it, complaining about how it was miserably hot and dangerous up there, when the high was in the low-mid 90's!
My reaction was, "HAHAHAHAHA" And thats the windy city! Try walking outside with stale HOT air, 102*F at 3pm with no source of wind, (sometime it in the 100s with 90% humid, which feel just plain disgusting) Nights are still in the high 80's!!

Not to start anything, i have alot of family in Milwaukee, and i understand them, i don't think i could live out the winters up there!! haha


BUT BACK ON TOPIC!!

A/C removal isn't much of a HP gainer, as it is a weight reducer and comfort stealer! I scraped mine for 2 reason, I Never used it anyways, and the pulley started making a high pitching rattling squeal.

And you being from NewYork.. i don't think you will mind summers with out a/c if us Texas guys can handle it!
