Default can i just take off the A/C belt if i don't use A/C?

this is a trick a friend with an integra used and since i hate A/C and i have a freeon leak i thought maybe i should just take off the A/C belt until i get that fixed... any adverse effects of this?

No but no benefits either. As long as you don't turn the AC on the compressor clutch is disengaged and the pulley frewheels, so there is no loss of HP.

i somehow knew subaru would engineer that better than i thought.

they did enginer the divice well, its just that on such a small motor that is much more noticable, like on a V8 you don't notice it because the engine is so much bigger than ours.

Actually, I am looking to take my ac unit off my car. My RA roof vent is on order now.
How involved is it in taking it ALL off?

This is hardly unique to Subaru, all automotive AC compressors work this way with an electric clutch.

I might be wrong, but doesn't the defroster use the A/C pump whether or not the button is pressed to engage the compressor?

Yup, just unplug the connector on top of the A/C compressor, then you're just turning the pulley, not the compressor. Turning the pulley only wouldn't take even 1/4 hp away, so I would leave belt on, unplug compressor clutch.

Try bypassing your powersteering pump. Some models/years respond better than others to this, but you do get some response out of it. AND the feel for the steering is alot tighter, like a bmw. I havent had a PS pump for almost a year now and wont go back.

i dont know, but my friend took his AC belt off and said he noticed more gains from it, than from the lite weight pulley.

Yes the compressor does run in defrost mode, at least in recent Subarus. In those with manual HVAC controls this can easily be defeated to have full manual control of the compressor, I did it a long time ago.

Did you drain the rack, or just remove the PS pump? I have seen some people just remove the belt and the rack was damn near impossible to move since you are pushing tires AND fluid.

Its just a long matter of unbolting ALOT of stuff usually. Its a pain but you lose a few pounds.

If you remove your powersteering, you can leave the fluid in but it will overflow from the force of your turning. I did not drain my fluid but only because there is no drain plug that I could find.

it is illegal and a very heavy federal fine if you release R134 a refrigerant into the atmosphere. Have a shop evacuate the system for you then pull the system out.

BY federal fine. I am saying that you could easily buy a very nice ferrari with the money.

134-a a/c system is probably around 35 lbs. if you removed the compressor, condensor, lines, and evaporator. it would involve removing the air box and taking it apart. Lot of work. If open the system without recovering the refrigerant it could kill you, cause frostbite, and/or blindness. And the it would make the EPA mad. But im sure you already thought about that. It does free up some paracitic(sp?) drag, but it not like your getting 15hp or something. You may see a small gain but nothing great. If your not running the a/c for a couple of months you can remove the belt, it only takes 10 min. or so to pull it out or put it in. It make it a little more peppy, i guess.

Sorry. I was answering your question, as in when one puts a question mark at the end of a statement.
