I can't bear the thought of losing, I dread the attention winning brings

ok i was thinking today

me being in the automotive field, and loving anything that adds power (ie BOOST)

when air is compressed it creates heat, hot air is not dense air, that is why turbos run intercoolers, and supechargers run aftercoolers

anyone have any idea how effective a cooler placed on the outlet line would be?, would it effect anything in the first place?

im just thinking outloud

This looks great, so I'm working on stealing your idea. I was just wondering though since I suck at wiring if you or anyone could draw up a quick diagram for powering this thing. Specificially if I didn't have A/C to begin with. Thanks.

its simple... just need 12v from the battery to a on/off switch.. the switch goes to the pressure switch and from the pressure switch to a/c clutch.

Just what fittings you use to connect to your compressor. That should be it.


On a side note, I don't know if it has been mentioned earlier, but I also removed my a/c condenser since it is no longer needed and it will allow more airflow through the radiator.

That makes me wonder..........with a few plumbing changes couldn't the ac condenser be used as a trans cooler?

ok im hijacking but the question was asked...and the answer to trans cooler out of an ac condenser is no. trans coolers have "tanks" and several "cores" running out of them so flow is not decreased any.....ac condensers have one line in thats runs back and forth and remains one line from top to bottom start to finish...in short they dont flow enough...just finished my flow and pressure testing on one off my 91 parts xj. and those are my findings

Help on hooking up the toggle switch....

I've read the thread over and over and I think I have everything understood except where to wire into the a/c clutch. Could you please take a picture of where all your wiring connects that would be helpful.

Thanks

I just cut the factory compressor clutch connector off the vehicle side of the harness and spliced that end onto my wire going to my pressure switch. That way I can connect and disconnect like normal.

I then wired a toggle switch that went from B+ to the pressure switch and then from the pressure switch into the vehicle and mounted it to the dash. Then I grounded the other side of the toggle switch to a ground point under the dash.

When the toggle switch is turned on, it sends power to the pressure switch which then turns the compressor on if the pressure is below the set pressure.

I may be forgetting something. I had to remove all the parts last year because the vibrations snapped a couple fittings off and I lost my inlet filter and my water seperator bowl cracked and leaked air.

I want to rebuild it sometime and I will use a better plumbing system.

Read throught this article. I got most of my information from here.

http://jeep.off-road.com/jeep/articl....jsp?id=257802

I did some things differently. There is a schematic for both wiring and plumbing. I used a toggle switch to turn it on or off.

Thanks so much. That link is alot of help. It goes into pretty much every detail needed. I'm jealous of the your low cost. I'm already at least a hundred dollars more than you due to having to pay for the refrigerant to be drained and full price for a tank, which doesn't come with a pressure switch. But what can you do......It'll still only run my about two fifty so not too bad. I just got my rig and have to fix a few things, but I can't wait to get it off road in the Uwharries and see what it can do. I might even half to plug in an air grinder and trim a few body panels while I'm out there.

I bought an a/c to oba system from someone parting out his YJ.

My Jeep is a 97 Cherokee 4dr 4.0L

How did you guy run your lines to the back of your jeep? I dont wanna cut holes where water might leaking into the cabin during water crossings.
