Removing A/C? (1987 911)

[Woodyhfd]

Do aftermarket compressors mount to the stock bracket? This could have an impact on whether or not I go through the trouble to remove the bracket.

[Barrpete]

The Rennaire system with the Sanden 507 compressor uses an adapter that mounts to the stock bracket. Not sure about others.

Took mine out years ago. On really hot days I just drive the other car that has AC.

Having just gone the opposite direction of first trying to save the R-12 system, blowing hoses and receiver dryer, then cutting my "losses" and replacing almost everything with RennAire components, and spending close to $3000, I have some perspective.

Why did I choose to replace it? I guess resale was a consideration and a compulsive "everything must work" mentality were the primary drivers along with reduced noise level when on the interstates with windows down also drove me to do it.

So, am I pleased? Pleased yes with the cool air, not so pleased that I spent so much money, resultant "guilt" that because it's a Targa (or could be a Cab) just taking off the top would have been an option. It's not a commuter car but is driven several times weekly with AC needed only from May perhaps to late September so in reality I could have endured. As others have commented, it all depends on where you live, so for Florida, I would be moved to retain it.

Interesting to me was the unanticipated change in how the car sounds. With no AC running it sounds fresh and eager but with it running the sound is more bassy and sluggish and it feels like it is lugging from the extra compressor load.

OK, sorry for being long winded but to those who have removed their systems, does anyone have a good evaporator motor to sell? After all I spent, the one thing not changed was the stupid motor which now squeals and I can't bring myself to spend another $300 for a new one!

I guess I am more like you. Oklahoma has HOT summers. It was 103 degrees today and will be that hot tomorrow. I will drive my 85 Carrera to the local car show tomorrow and be very comfortable driving home. It would interesting to see just how much the AC system wieghs. I drive my car way to much to go without AC.

I prefer everything to work as delivered or BETTER than stock.

Having all of the AC stuff in a box sitting next to my fence by the garage, I can say it is north of 100 lbs. I took everything off though....compressor, bracket, hoses, 3 condensers, fan, etc...

Anyone need some old stuff? You have to come and get it

this months excellence has a stoey about the quest for cold a/c in an sc.

3k goes a long way in other areas of the car - so it's low on the list for me. But the mines is a Targa and not a daily driver.

Does that $3000 include failed attempts to repair the original system, or was that just the cost of the new stuff?

$500 was due to the failed attempt however I still have another $300 to spend for a new evaporator motor which may also require removal to the evaporator assembly which then means evacuate and recharge the system. Even if it was caught earlier the motor cost would have been the same. Then of course there is still a need to do something to protect the Desert Duty front condenser from road and other impacts.

So winter is coming and I have 5 months of non driving, I have been contemplating removing my A/C for a year.
1) its a Targa so if its hot, I have the roof off.
2) it only blows slightly cooler than the ambiant air and
3) minus a hundred pounds and not driving a compressor sounds good to me.

I think I have another project for the winter, I will just add it to the list.

If you were in Kansas I would advise against it. We would get up early, EARLY, drive the early morning with the Targa top stowed, stop for breakfast about 10-11AM , and then put the top up to get out of the hot, beating, noonday and afternnon sun.

Anybody have an actual weight of a complete A/C system after it was removed or the hp it takes to drive the compressor (even when turned off)?

This was helpful when I deleted mine:

Reviving an old thread. I removed the compressor and rear condenser over the winter. I recall the compressor mount hard to get out of there but not insurmountable. I zip tied the lines in the back because I didn't feel like dealing with it all at the time.

Now I'm working on the front end. I'm installing Rennline tow hooks on the front of the torsion bars. The front condenser and it's related guard are in the way. It looks like there is no easy way to tie off the lines without pulling them through. The car is used mostly for DEs but there's a small chance one day I'll want to put the air (upgrade) all back in. I'm reluctant to pull out lines because 1)they don't weight that much and 2)the might help in pulling new lines through.

Question for the board, If I decide to remove the front condenser, any simple way to deal with the lines without a "hack and pull" job?

thanks
