Drastically lowering IAT....

[SC2150]

Here is a picture of the heat exchanger/cooler that mounts behind the bumper cover:



This is where the heat is removed from the intercooler fluid.

So this isn't an auxiliary cooler, it completely replaces the current system's intercooler?

No. It integrates with it and cools the intercooler coolant. On the average intercooler you have the intercooler in the grill, and the coolant in that system circulates to the heat exchanger under the supercharger. This takes that coolant and chills it down drastically from what the ambient air can.

There is no such thing as a stupid question if you don't know the answer. So ask anything you need to understand it all.

Neat idea, so you will be able to turn the "super chiller" part on or off right?

Okay - let me see if I can understand this:

You are interrupting the flow of the SC intercooler coolant by running it through this chiller. You are tapping into the A/C line to run refrigerent through the chiller to cool the coolant. So, the individual will use the chiller in addition to the SC intercooler's heat exchanger? A person can also control the chiller circuit independently of the passgenger compartment climate control and either split the refrigerent between the two or solely run all the refrigerent through the chiller? I see three ports of what looks to be about the same size on the chiller and one smaller one. Is the smaller one for the refrigerent line and the two others for the coolant? I don't quite understand what the forth port is for... Also - is there a return line for the refrigerent, too?

Wow, great questions.

Correct. The switches are 2 small micro toggels, like an electric guitar has.

You got it! Excellent understanding. Yes there is a return line, and an additional orfice tube. Just as a rear AC would be in a van or a SUV, but the chiller has two seperate chambers where the freon & the coolant pass each other providing maximum heat transfer.

Absolutely. These are the question I want to see in this discussion.

There has been a ton of R&D put into this and the working units are doing great after app 6 months in use on a few test LS powered cars.

[Kyle2k]

How long will the cooler temperatures last at WOT after the compressor disengages?

[2KWIK4U]

I would assume that when you turn it off it wouldn't last very long, just like your a/c does. I bet your wondering if it will last long enough for a run without the drag of the a/c compressor, right?

Probably for only a minute or two, but at the dragstrip you will only need it at WOT for 11-12 seconds or less, and for a roll-on race say 30 seconds? After that you have the same cooling as it would w/out the unit.
As for a road-racer, the question would be "will the drag on the engine from the AC compressor wired to be engaged at WOT as well outweigh the benifits of the cooler air charge temps?" Thats an unknown at this time, but the GTO running this for the past 6 months or so is street & dragstrip driven with excellent results.


Good question though!

This looks VERY nice.....

You mentioned no condensation to drip onto the track. There is no condensation from the chiller's interface between the coolant and refrigerent then?

Are or will you guys be verifying this?

Thanks for all the details

I don't think I'd mind if I had to sacrifice some A/C performance for better engine performance, but not knowing much about A/C, I imagine if there is a bigger draw from cooling the charge, that a larger condensor would require more refrigerant and that would make up for the draw All I know, is this sounds pretty cool

You have, its called the killer chiller. I have been talking to the owner Joe for the last few months for developing one for GM cars. I believe one of the GTO guys did one this year. The Ford guys have been using it with great success, as low as 45 degree water temps with the outside temp around 75. You can see some videos on youtube, awesome results! When I install my Eforce this winter it will be the first thing I put on, and believe it or not if you run a H/E it actually counteracts the KC because it will warm up the water on a hot day. I am going to run a 3 gallon insulated tank straight to the KC and insulate the lines to keep it as cool as possible.

I am very currious to see how your chiller performs, I like the idea of the shut off to the evap and just freon to the chiller. The only negative I see is that the unit is not insulated like the KC is, do you plan to insulate it?

If you ran the chiller AFTER the heat exchanger, you get the best of both worlds.
