[quote=""tabasco122""]im pretty sure its just the air. my car has no AC or heat, and i just blast it with normal air and it gets rid of the inside dew...[/quote]

Air will eventually get rid of it, but low humidity air from the a/c will clear the window much faster, and better.

test 3: REALLY HOT DAY

really think it failed at this one. So hot that you cant sit in the seats as it burns you hot. I start up the car windows down, get moving, and then turn on the ac. It takes it some time to feel cool air out of the vents. So I roll up the windows and it just isnt getting cold fast enough. Its getting cooler but the window down and air blowing on me feels cooler then what the ac is doing. it kept getting cooler the longer it was on but it was just so hot.

At this point I almost want to try the condenser that was much longer...same tall but much longer, almost a whole extra one from what I have. It will cost me 50 bucks and then another 50 in refrigerant. I need to get the high pressure switch anyways so it would be a good time.

I could add that bigger compressor for around 150 that could do a lot more work.

I just thought of something crazy.

Do you still have your stock AC parts?

did you vacuum down the system and recharge it yet? I'll bet that is your problem. I know it sounds minor, but all it takes is a tiny amount of plain old air to make the difference between 40 degrees and 80 degrees at the vents.

no, been waiting on more refrigerant. I will deff do this though. I almost want to buy one of those pumps. ac is a good thing for me to work on while at work as if I mess anything up it doesnt effect the running of the car.

Yeah the reason it didn't get cold is cause it doesn't have the proper charge of refrigerent.

I'm still concerned about airflow over the condenser.

does your work have a good air compressor?

yeah, it gets cold but it needs to be colder. I think you are right.

[quote=""Gatecrasher""]I'm still concerned about airflow over the condenser.[/quote]

Ok I know there are alot of variables so lets hatch some of them out.

Even with no air flow, how long would it take for a condenser to quit doing its job? How long does it take to heat soak it? (yes dependent on size, amount, bla bla bla) Are we talking 2 mins or 20 mins?

we do have one but were not allowed to use it as its hooked to our trucks plymovent system.

I know I am right. There is a specific amount that needs to be in there. If there is too much, or too little, the system WILL NOT WORK RIGHT, PERIOD.

Do you have a fan on the condensor? If not it will quit doing its job quickly. If you have a fan it will take quite a while.

Bump :evillaugh:


Seriously I remembered you mentioning freeze 12 so I searched for it since my camry still has a cold blowing r12 system.


[quote=""DCIV""]Ok ordered everything, hose, fittings, weld on fittings, condenser, drier, compressor, service ports. Everything and im still under 500 right now. Turns out one of the firemen I work with is the AAA guy in town (knew that) but he does ac charges with freeze 12. hes been helping me out with what I need recently. I got all push on fittings, extra hose, multiple fittings, only thing left is mounting the compressor, and mounting the condenser with air holes for it. I got a cool in line drier too.

Coop[/quote]

So I decided to look into the freeze 12 a little more. Its not available anymore but the es12 is. Dug up an msds for it.....you might like this coop.


Its liquified petroleum gas. Essentially propane. :)

yeah es12 is what I went with. The cans basically feel empty. Its good stuff, you cant underfill or overfill depending on what you need. My only issue is that its just not as cold as the old stuff.

I guess I should give a little update, I never put a high pressure sensor in the system because I was just testing before I did all that. It worked enough to make me happy but it would blow lines. Kind of scary when your running propane and your line blows under your engine bay. While its down for a new VCU and some new wastegates I will prob add in a high pressure line as I am going to keep it.

Oh....it is. With the amount of es12 I had to use as well it was not good at all.

After reading some of this I was leaving work and noticed a semi truck that had a rear mounted condensor on his cabin... Interesting....
Did you ever vacuum the system and remove all the moisture?

Yes, it was all done completely correct. Had a vac on it for 30 mins and didnt leak any. I plan on getting the next size up compressor as it fits my mounting bracket I made. I have seen them on semi's as well.

Work on the condenser before you put a larger compressor in.

I have found one that is the exactly the length and size that woudl take up the whole thing that I have though about using. Would you mind elaborating on why you think the larger condenser would help before a larger compressor?
