air condition your cold air intake

ok .... I've had a few beers again .

not sure if this defies one of the three laws of thermodynamics ( you can't get something for nothing) , but why couldn't you use the AC to cool a cold air intake box instead of the car interior .... would the HP gain be off set by the loss of running the AC ?

How cold can your AC go? I doubt the temperature difference caused by hooking it up would outweigh not having it at all.

There's always the option of adding CO2 to your intake, heck of a lot colder than your AC will ever be. I think cryo2/DEI is the company that makes it.

If it worked good enough to be worthwile, you would have heard of people doing it allready. So i'm guessing, no.

you'd be better off running an intercooler on a naturally aspirated car honestly.

The power loss from having your AC on would be much greater then the power gain from cooler air. Go play outside. K thanks.

The problem with that is, CO2 won't add any BTU's to combustion, so its just taking space. Unless you are talking about the bulb that severely limits the flow in exchange for a little bit of cooling.

The supercharged lightning has a button that cools the intake using AC, but it only lasts a bit and takes a while to "recharge". Think "it takes energy to make energy" the point of it is to run in a drag race, you are only on the track, WOT for 14 seconds, the engine does work (running AC) while you are off the track, It then releases energy when the air is cooled. It simply diverts the air from the normal path to the new cold path, then back again.

A better way is to use methanol injection. Methanol will cool the intake air and also provide BTU's during the combustion process.

like papiogxl said i would run NO ac, but would run methanol injection. i have had some experince running propane injection on some diesel engines (kinda the same idea) and it rocks, huge power gains. look into the methanol man and get rid of the ac.

i doubt the ac could put out enough cold air for that

So.. wouldn't running an intercooler on an NA cause more drag in the intake system? Would the added temperature drop compensate for the increased drag and possible lean condition? It would be like trying to breathe through a garden hose.

The Lightning systemw as called supercool, and it was never introduced as it was for the 04 lightning that was canceled before it was released. It cooled the liquid used in the intercooler in a seperate tank and then released it. Was supposed to be good for 50 due to colder temps and increased timing for about 10-15 secs. And the lightning was MUCH faster than a 14 sec car.


Using the AC to cool the intake is a loss. Some guys in the GN/GTP community have used to to pre-chill their A2W ICs, but short of that it doesnt work. The CO2 Option on an NA car is worthless, but for an A2A IC spraying CO2 can help out. (you dont spray CO2 into the intake....)

Wasn't too sure on the specs of the lightning system, and I added in the time you would flip it on before the lights went down lol

the system was acutally pretty sweet, and i was really disappointed at the time that they didnt continue the lightning. I was sporting a 13 sec GTP at the time and I was waiting for a few of those lightnings to end up in a junkyard so I could scavenge the system for my intercooler.


The system was supposed to be push button. You hit it and it would instantly redirect the stored fluid. honestly Im suprised it didnt find its way on to the new GT500. Would let Ford call it a 550 or even 600 hp car without all the abuse that 600 constant hp can do to a car.

hmm....i doubt the setup will actual be useful in real world application.....the air needs to be pulled through the cooling core to lower the temp.....now imagine how much air is ingested by the engine to produce power..all that needs to be passing through the core.......if u really want to lower heat transfer just ceramic coat the intake runners and call it a day

Running an intercooler on a na setup has nothing to do with drag on the intake system. The reason no one puts an intercooler on a NA vehicle is because an intercooler can only cool to the ambient temperature of the air around it which is what your intake is going to suck in anyways. The reason turbo vehicles use intercoolers is because under boost the compressor is actually heating up the air during compression and is pushing out air temps 100 degrees plus thus the intercooler at ambient temperatures, ~70 degrees fahrenheit, is actually cooling the intake air from the turbo.

i forgot to mention.....to whoever suggested injecting co2....obviously havent taken a chemistry class.......co2 do not burn.....infact it would take up space otherwise filled by air...

Yeah.. I knew this.. I'm not really sure why I even thought it would work....

uh yah guys listen to torean... co2 is what they use in fire extinguishers...

although you could spiral wrap copper tube (or aluminum) around an intake pipe and inject co2 through the tube cooling down the intake charge

the thing is, NO ONE suggested doing it. Someone ASSUMED thats what another person was saying, but no one actually said it. go back and look. There was something said about using CO2, but no one said that you should inject it.

Wrapping the intake tube with copper or steel tubing and running CO2 through it would also be a waste because the only thing that would cool down would be the air that touched the intake tubing itself. Now you could make an argument about spraying the intake manifold with CO2, but really we are just getting stupid then. There are better ways to make power, and thats not one of them.

Ayone who has felt a co2 cartrige after use knows that it is is very cold. I know why cant IU can thinkg stragight form alcohol so I cant explain. Anyway, couldnt you use something like the vapochill for the computer? Its basically a refrigerator compressor that chills the air to -40 degrees. It might overlaod the electrical system though.
You could plug it in to the wall boefore a drap race, or something, thogu......

well i'm glad there was a litte discussion on this ... not surprised at the results though. interesting about the lightening

anyone know the CFM flow of the AC versus through a large cone filter at 5-6K rpm? .... the intial thought i had yesterday was an ac line into a small insulated CAI box that the cone filter was mounted in and a switch to redirect the AC flow to that box when you wanted to ... though i never notice more HP when I drive when its cold or hot out anyway
