I was driving to work on a hot day, and i came up with an idea. <P>Would it be possible to port the Air conditioning compressor to feed the Intake.<P>The compressed air coming out of the ac would be atleast 20 degrees cooler then regular intercoolers, covering a greater volumetric area. <P>The ac compressor like a superchager does use up the engines HP. But the positive boost will outweigh this negative. <P>Porting the intake would be very easy as well. A BOV might be needed to release extra boost. <P>Also the AC needs to be on all the time for this function. or a split chamber could be made(with a on/off switch) to close the ac intake and open the regular air-intake. <P>But this system might work. <P>Please reply with anything i have overlooked or any reasons why this would not work(im sure there might be many). <P><BR>Thanks

I think your on to something here, I was considering making my own wet sprayer from wiper rinser pump to mist into the intake when it is especially hot or when I just need that extra push. There probably is a kit out there somewhere doing these things.

Its been discussed before, and there is no way to make it efficient enough to boost overall power. To make it produce power, the load upon it will kill all the power you just produced. <P>sorry, but its not the first time this has been brought up, it wont be the last, but the answer remains the same.

SO i guess the load is far greater than of a supercharger?<BR>has anyone actually tried this allready? or <BR>the answeres are from theory.<P><BR>thanks

"I was considering making my own wet sprayer from wiper rinser pump to mist into the intake when it is especially hot or when I just need that extra push"<P><BR>It could work. never thought of that before. <BR>good idea

i dont think it is that far out of reach. the ac compressor can achieve high psi ratings in an ac system-- as far as a intake system i dont know. you would have to find a wastegate sytem for it. as for cooler temps -i dont think so. i think it would be hotter than a supercharger. the basic construction of the compressor would also reqire the compressor to be oiled internally--if you can figure these things out youll be set.

"i dont think it is that far out of reach. the ac compressor can achieve high psi ratings in an ac system"<P>Boostedmx<P>I did a little research, and your right about the ac compressor. The system can handle and does operate on very high psi, maybe at times even to high for the intake. <BR>also not to sound ignorent, but doesn't the ac compressor have a self lubricated internal structure?

hmmmm... interesting idea. im wondering if you are saying that the engine would rely only on the AC or would it use the regular intake air as well? because i doubt the AC puts out enough air in the first place? but i could see you getting a few psi of boost of such an idea plus cooler air as well. i would say give it a shot diablo... i would love to see how it turns out.

umm, there is a HUGE difference in air volumes in an A/C system and trying to compress ANYTHING into the intake tract. <P>It wont provide near enough air. Trust me on this...it DOESNT work. Its basically like an E-ram with cool air. BAD IDEA.

After more research, your right it would not be an effecient system. but i did find the system inuse, only amongst drag racers, that port their a/c to the intake right before the go to cool the internals. but the system is shut off once they start. <P>Thanks for the inputs everyone!

its not going to be cool air to begin with. in order for the ac system to produce cool air it has to be a closed system. did you forget it also uses freon? and where does the air come from? --in its own CLOSED system. not cool air form the outside---these systems are modified to pump up air tanks for use on lowriders with airbag systems. to compress air in an air tank is a task. maybe a little slow but like i said they are modified to get them to that point. the possibility is there. i never said it would work definately but it is an iteresting theory. just being optimistic i guess

What if you plumbed it in before the MAF/VAF? It would use the same air intake, just cooling it down a little. OR, maybe plumbing it in before a turbo or SC, or maybe just before or after the I/C. Wouls the cooler A/C temps help cool the intake air? or would the boost running back up the line destroy the A/C compressor? Would a BOV correct that?

Well, hopefully everyone has figured out that the A/C compressor couldn't be used to cool the intake air charge since it isn't sized to perform this task. If it was, then the compressor would consume about as much power as the cooler intake air would produce.<P>However, this has always been a problem that perplexes hot rodders...how to cool the <BR>intake air below ambient temperature? <P>There are liquid to air intercoolers which use chilled water but it's necessary to chill the water which requires energy or the additional weight of ice. <P>How about a freon to air intercooler? A bottle of freon with a solenoid valve is opened by your lead foot at WOT, the freon is discharged through an expansion valve, cools the intercooler, and it collects in a separate tank. The system has a separate compressor whose clutch is engaged by a switch controlled from the cockpit when you are just cruising and the extra energy drag won't bother you. The compressor takes the freon in the collection tank and compresses in back to the high pressure tank.<P>Just an idea.......nahhhh, way too complex and nitrous is much easier.
