i did a search and found nothing. i was wondering if it was possible to use an air conditioning system as an intercooler, much like a water to air system??? i don't have any reason to build it(currently a N/A setup). just wondering if its possible, if anyone as done it and what the pros and cons would be
obvious pro = very cold air
obvious con = hp required to run pump
I would imagine it would cost more to get it to work then just purchasing a co2 intercooler sprayer kit

it would cost next to nothing for a car already equiped with ac. just rip out the one in the cab and mount it into the the piping. i was wondering more along the lines of condensation (water into the engine) being a problem

You're not too familiar with heat transfer are you?

How are you going to seal a ~2.5" pipe to the big rectangular heat exchanger?

oh dont worry its simple, remember that toy for children where u put the shapes in the correct hole, well all u gotta do is try and get the square one in the circle... im still attempting
lol
fab up a peice of aluminum that tapers from 2.5" to a rectangle, simple enuf, just gotta do a little aluminum welding. if you could find a smaller heat exchanger and mount that up it would be easier

I am.... But all I said is it would be easier to just install a c02 intercooler kit to spray ice cold co2 on the intercooler... i don't understand what you meant by that

I was inferring that it doesn't have the same effect. Also, there's no constant bottle refilling.

no bottle filling and a very short piperun between the turbo and tb. no need to go out of the engine bay
I've considered doing this for a while. Consider that you might be able to use the evaporator from another car if it has a more suitable shape. Just look on eBay till you find what you think u want - then go visit a junkyard and pull one from that same car. As for sealing it, just build a aluminum enclosure for it. Weld some plates and cut holes for coolant lines to run though, cut a hole though the plates on both sides to weld a small aluminum pipe to both ends. Weld to seal where the coolant lines run in. Other than that, it is mainly just rerouting coolant lines and recharging(since you're obviously gonna need to discharge what what originally in there) your AC system. Easy stuff.
There really is only one downfall IMO - that on most cars(not 100% about J-bodies but I guess I could find out) - the AC system automatically shuts off at 70% WOT or so. Of course you could also look into removing that autoshutoff feature for the AC - assuming that J-bodies even do this to start with. But really, such an idea may be more ideal to cool off water in a aftercooler system. You could pre-cool the water before your run. Plus that idea would remove the AC compressor drain on engine HP at the time that you are running.
I've never heard of this "part throttle" before. Does it just bolt on?
You will also have a lot of "waste" water to deal with. Have you ever noticed how much water comes out of a HVAC case when the A/C is running?
that waste water is my main consern with the whole idea. don't really want that getting into the engine. i guess you could rig up some sort of float system in the bottom of the enclosure that would be lifted by the water once it got high enough. although under high boost the pressure pushing down might not let the float open
i always thought of re routing an ac ducted into the engine bay shooting air onto the parts to keep things cooler... i never actually tried it, or ever said it out loud, lol

Not to bust anyone bubble here but lets really look at this now...
The best Cyro and N20 kits that spray on intercoolers make about 25 extra HP and thats like -30 degrees..
So your talking about running your Ac witch alone normal driving uses about 10 hp on a cavalier to run and your going to put such a Heat load on it that the Coil in front of your Radiator is going to reach temps well over 200 degrees. witch means your car is not going to cool the coolant as well which means more heat and loss of timing and loss of HP. so maybe you might break Even but at the cost of Killing your car...
I do HVAC for a living the theory behind AC is moving the heat from one place to another.. the loss of heat in one spot results in cooling.. Although there is much more to it than that....
But your Ac system works like this.. the higher the load on it (the temp its trying to cool) the harder it works, and in a cars case the more HP it needs. thats why after your car is cool inside you don't notice the hp loss as much cause the compressor is not trying all that hard.. The most that system was meant to see is around 150 degrees... and now your talking about throwing somewhere around 200 at it at a constant rate.. it wont ever get cold and your car will be using around 30 hp just to spin that kind of load..
thanks for the info... thats what i was really looking for. i knew there must be a downside or people would be doing it. i just didn't know enough about the systems so i asked. thanks for the imput guys but with those kind of numbers it doesn't seem too logical and i don't think i'll be trying it soon
Ford had been looking into using the a/c system for intercooling purposes on their s/c engines, but I haven't heard whether that's still in progress or if it's been shelved entirely.

that would be an interesting thing 2 watch out 4
