Yeah, i know dead thread. The idea has been quiet for a while but i haven't completely stopped thinking about it in my spare time.

So anyway, i ran across these.

and was thinking, how well would it work to use these AFTER the intercooler (or anywhere in the intake piping for that matter) and run Freon thru them from your A/C system instead of regular engine coolant?

Naviathan mentioned something like this using copper wrapped (inside?) pipes.
And Shady said he was gonna try it out, but i don't know if he ever pursued it. Did ya Shady??

 

Looks like a waste unless you are running some huge about of boost and pushing crazy hp. Lots of talk on that page... did they dyno it for proof?

 

Ok Ok Ok...Mike to the rescue. Look, what causes the drag on the engine when the A/C is engaged...the crank turning another pulley right. So remove the belt from the A/C compressor and install a 12volt electric motor to turn the compressor instead of using the engines crank to turn it.

Running a "tube" to the intake track after the turbo is not a good idea as the boosted air will overpower the A/C's air and will cause a boost leak. You can run it to the front of the IC but unless you have alot of pressure coming out of the A/C tube it's not going to do too much. Unless you can mount a refrigerator/Freezer coil onto the front of the IC to cool it as the car moves I don't think you are gonna see too much of a cooling effect.

Run a spray bar on the IC and connect the pump to a switch under the gas pedal so it only engages under full throttle. Run a liquid in the spray bars tank that has good heat transfer properties and is cheap to replace such as water or alcohol. If you are not racing then you don't need super cooled air...right? So why have it super cold all the time?

One of the easiest ways to get more power is to use an oxidizer such as N2O. The gas itself is not flammable, but it delivers more oxygen than atmospheric air by breaking down at elevated temperatures, allowing the engine to burn more fuel and air and resulting in more powerful combustion. Also the evaporation and expansion of liquid nitrous oxide in the intake manifold causes a large drop in intake charge temperature, resulting in a denser charge, further allowing more air/fuel mixture to enter the cylinder. The lower temperature can also reduce detonation.

My point is if you want cooler air and more power then add some N20 and rock the hell out
