searched the last 45 minutes.. could not find an article.. I want to yank out my AC and compressor

how much power do I get?
do I need a new belt?

mr links.... ily..

 

The gains aren't noticeable.

Here's how it goes:
-remove battery
-remove the belt
-unbolt 4 bolts that connect ac compressor to block
-disconnect lines.
-pull out

you are going to need a shorter belt, but i forget the size. if you search well enough you will find it here on the forums.

 

i used to have the part number for the new belt memorized. so yes you need a new one 20-30 for a nice decent goodyear belt.

 

This is from a post I made almost exactly a year (and 2 days) ago

 

The ECU disengages the AC clutch under WOT so you'll not see measurable power loss there. All the AC hardware weights about 40 lbs, which is lighter than some people's gut.

Removing AC on a street car is a dumb fetish and has nothing to do with power gain - and is all about giving the appearance of it.

 

^^ luckily i removed mine for different reasons. My AC clutch burned out and it made this horrible noise whenever i would turn on the car. And it was smoking lightly from some black stuff coming out from behind the compressor wheel so out it went

 

The same amount of power that you'd get with the A/C turned off. There is no real difference in load between the system being turned off and the compressor being removed from the car.

 

that makes sense then... I take it the air pump doesnt turn off? or is it just another "less clutter" item?

 

The air pump clutch is disengaged at 3k rpm by the stock ECU (2.5k rpm by the PFC).

 

I have my airpump disconnected, I bought my car as a blown motor.. but it was just a bad bearing or something in the air pump. weird

 

the main reason for removing ac or the air pump is to merely simplifiy the engine bay and shed a few pounds of weight.

 

ok cool, I knew that part but I was under the impression they both sapped power.

 

Like everyone is saying on this thread...You will not GAIN any power by removing your air pump or your A/C. They both operate using a magnetic clutch, which means when they are not needed or running it is just an idler pulley. Your a/c will disengage at wot and your air pump will disengage after a certain rpm. The only so call "gain" would be a reduction in weight (not much if the car is a daily street car). The only time I would say you should remove it is if it is malfuctioning. Reasons to remove A/C or air pump is if it is seizing up or you hear bearing noises. The only other time you might want to remove the air pump is if you have turbo setup where you need to run the intercooler pipes in that area. Any other reason(s) to remove would be purely cosmetics.

 

air pump is seizing up... but once again, if I remove it I need a new belt. I see these air-pump eliminator pulleys?? can I just get a belt from Murray's and be ok or is it special order type deal?

 

you also gain some airflow to the radiator with the condenser gone. if you do decide to pull the a/c you should go ahead and pull the power steering as well.

 

idk about pulling the power steering.. lol. but like everything else listed here, is the power steering the same deal?? no real power gain blah blah blah

 

i would love to remove my ac and powersteering, all that **** outta the engine bay would be awesome. the black interior is just to god dam hot to run without ac though.

when guys remove both the ac and ps do they also remove the mouting bracket that is attached to the side of the block? if so, how to they retain the tensioner bracket for the alternator?

 

the car is light enough that it really doesnt need power steering. i would think it would gain the most hp but its probably not alot. the main thing is the engine bay is alot simpler easier to work on. and less objects to heat soak.

if you plan to remove the a/c you might as well remove the PS and the air pump. Converting the steering rack to full manual is best but looped lines are fine too. i would remove the PS before i would the a/c. the a/c does more for me then PS. you also gain increased road feel without the PS which allows you to "feel" whats going on with the car.

 

hmmm... the power steering thing is tempting, any way i can just sample it? removing a fuse or something?

 

^^u can try it by removing the belt

 

how much power gain is "not a lot"?

 

removing the belt wont yield the same results, the pump is still in the equation and the fluid has to be forced and overcome. the road feel will not be improved either. though even with the belt disconnected its still not hard to turn. you will at least be able to feel if there is a power difference. aside from the performance gained from weight loss. i wouldnt count on it being a good basis for how easy it is to turn by just taking the belt off.

i dont know how much is not alot. if i were to guess i would say 5hp if you removed everything. but maybe its more. the main thing is if you decide to remove the a/c you might as well get rid of it all for the biggest gain. both in power, weight and simplicity.

 

i think removing the belt will give u a pretty good indication of what no power steering will feel like, i had a powersteering belt off on another car and it was exactly like having no ps.

 

yea, im just looking for the feel

 

It's terrible, I have the belt off right now and it's much harder to turn, hahaha.
