Unless your car is ripped apart its going to take more then 20mins...if you want to completely remove everything, the nuts by the firewall are a bitch to get at

i hate to bring back an old topic from the grave but can anyone post how removing the AC is done?

dvo 12-20-10 01:12 PM

I thought about removing mine but it works perfect and blows super cold... I decided to keep it in since it's not doing any harm

I used it so rarely so I removed all a/c stuff under the hood, including the a/c "motor." It probably only takes 2 hp to spin the thing, but removing all the under-hood a/c stuff removes about 15 lbs from the front of the car and allows a little more ambient air to circulate around the motor itself. However with the a/c on, the power loss is noticeable and definitely more then just a couple hp.

But if you drive in areas that do get hot more than just a few times a year, I'd recommend just keeping the a/c intact.

Been looking for thi info for a few days now. Good to know.

p00shy 12-20-10 01:56 PM

do you just remove the condensor, dehydrator and air pump?

i removed everything in the ac systems also remover thr p/s and got a manual rack looks alot cleaner under the hood. since i only drive my fd on the weekends it dont bother me to not have a/c or p/s but if it was my DD then idk if would of removed all them.

p00shy 12-21-10 01:57 PM

can someone point me to HOW??? i really appreciate the opinions but i would like to know HOW this is done. HOW do you remove the A/C unit and everything? She is going to be my weekend warrior and i live in San Diego so the weather is pretty much perfect most of the time.

Might want to check the FSM for that

and don't let anyone see you venting R12 freon into the atmosphere.. i'm pretty sure that the EPA would love to throw you in jail if they saw you doing it. i'm sure there is some shops that will evacuate the system for free since R12 is valued close to it's weight in gold mainly because it's an uncommon freon these days so they charge more for it.

granted most of these systems are bone dry by now anyways..

as to answer the original question, you lose a fraction of 1% of your horsepower, netting you maybe .5WHP more(yes, half of one horsepower) when the a/c is turned off.

If your ac doesn't blow cold you are probably out of freon so no need to drain
Remove the belt
Remove the condensor..the piece down under the radiator
Remove the lines...they are just held in with screw clamps
Unbolt the compressor and remove it...it is on the driver side of the engine near the ps pump

Keep the blower under the dash incase the next owner wants to reinstall it.

^^^ That!

Dont go so far that you make the car impossible to sell if you ever need to.

neit_jnf 12-22-10 12:50 PM

doesn't the a/c automatically disengages the compressor at full throttle? so basically no power gains taking it out... when mine had 315whp my best time of 12.8@110 on street tires was with the a/c on!

moconnor 12-22-10 01:05 PM

Pretty much all cars disengage AC at WOT AFIK.

The only performance advantage would be from the ~20lb weight loss.

Its a pain when shopping for an FD these days, they either got the AC ripped out, PS ripped out, or both. Kids.

I have two FDs, and one was gutted like that, I had to put everything back in =(
I must be getting old. My current runner is bridgeported with a single turbo, it has AC and PS, nothing like the creature comforts while being able to whoop some ass at the same time.
Everything I've done to it is reversable as well since I have a stock engine sittin nearby.

No I agree with you 100%. I'm all for the creature comforts as its what makes the car enjoyable to actually cruise in.

I've been on other people's cars (not FD's) where they have no AC, no PS, gutted, with the ride so hard that you feel like your teeth are going to fall out. To make it ever worse they didn't even track the car. All of those people sold their shit within 2 years and they all said the same thing: "I got tired of it"
