I'm considering removing the air conditioning in my 82 SC. It doesn't really work very good and for the three hot days we get in Wiscosin I can live without it. It just adds weight and clutters up the engine bay. Before I do this does anybody have any good reasons why I shoudn't.
If someone has done this before, are there any precautions I should take first. Is there anything I should do to preserve the removed system in case I or someone else wants to reinstall it?
Thanks, Chris

I pulled the ac out of my 81SC. The hoses running from the compressor forward may have a little yucky thick oil in them. If you want to add it to the pile, like we all have, of the "somebody might want this someday", cover up the hose inlets/outlets, plug any holes. Suggestion: Put the parts up for sale now, or get out your multi-year calendar, and bet yourself on when you take it to the dump! Check the floor under the fan assembly in the boot - mine had some rust. It's a bit difficult to get out, just keep at it.
When you take the a/c out, then backdate your hot air source to the pre-74 variety (getting rid of the engine mounted fan) you'd be amazed at how much space is really available in the engine compartment.

I'll second Bill's suggestions. The A/C removal and heater backdate made a huge improvement in room to work, and took off I'm guessing 120#(?) of dead weight. To release pressure in the system I turned my front wheels full right (to keep oil off my left front wheel) and SLOWLY cracked a fitting on the filter/drier in the wheelwell. Saves a spraying mess in the engine compartment.

i removed my A/C compressor and evaporator from the trunk of my '80SC Coupe. unfortunately, couldn't avoid the "spraying mess." Wish i had known about Porschephanatic's recommendation.
However, i've never removed all the hoses. Do you just pull at them and they'll slip out from under the engine? A friend told me snip away at them with fence cutters and that might help slide them out.
Bill Gregory - how did you get your hoses out?

I recently removed the A/C from my 82 SC. I didn't have the "spraying mess" problem since my compressor had a leak in it. I left the non-functioning A/C in for five years before taking it out!
The hoses are a bit of a pain since there are a bunch of brackets every 8-10 inches along all the hoses that you need to take off to get the hoses off. To get to all of these you'll need to jack up the car, and remove all four wheels. After pulling each bracket off I screwed the brass screw that was holding it on back in leaving the rubber washer/grommit thing there too. I don't want any rust.
If you want to remove the external condenser and the gaurd bar that is mounted to the torsion bar end covers underneath the trunk then you will need to get shorter bolts for the torsion bar end covers.

Generally, the a/c system weighs in around 50-60 lbs.
On backdating the hot air supply, there's an article on tech.rennlist.com under 911 engines on how to do that, with the part numbers. Here's a picture of my 81SC w/o AC or hot air fan.

Ahhh, yeeesssss!
Now I can see my Motec conversion to TMW throttle bodies taking shape. Believe it or not, the potential heater loss was my biggest objective to overcome. Next is brake vacuum assist with the TWM setup.
OOPS. I'm going off topic.
How about "I'm planning to remove mine too". Compressor is already gone. Hoses, condenser, evap, dryer are next.

I removed the a/c from my 83 SC coupe recently. No pressure to release and only a few drops of redish oily stuff. Took out the compressor and the big bracket, leaving the smaller ones for an engine pull someday. All the hoses left and yes, I did cut most where applicable. Took out both condensors and the front blower, but left the guard bar in. I made up some hole patches out of galvanized steel and epoxied them in followed by pop rivets. Took all the crap out of the smugglers box. I left in the ductwork behind the cardboard piece at the back of the boot, but plugged the ducts in the smugglers box with some plumbing caps from das Depot. I took out the controls and the relay.
Damn glad I chucked all but the front blower - I'll take it to Hershey 8-)
