Drastically lowering IAT....

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.

Not trying to knit pick at all I just don't want anyone to get confused, the heat exchanger is in the grill and the intercoolers are below the supercharger.

I thought the same thing too at first, but think about it this way, lets say it is 90 degrees out and the road temp on a sunny day is easily 120. Your H/E is 12" above the road and pulling in that heat into the H/E, all the while I am trying to keep the water temp at 50 degrees! If you introduce that chilled water from a closed system back into the H/E you will actually warm the water up.

Are or will you guys be verifying this?

Thanks for all the details

Correct the condesation drip from the cabin is the moisture removed from the cabin air as it is recirculated. The chiller outside does not produce any more moisture than the standard AC line does under the hood.

Yes, it has been verified by some of the guys running the KC units. The KC unit works awesome as well, but is basically off the shelf auto AC parts, where this is all purpose built. Billet adaptors, etc. As most things I produce it is ground up designed for the intended purpose.

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?

Your 3 gal tank is an excellent idea, and you are correct on the reverse effect in very cold conditions. Remeber, and AC system removes heat, it does not generate cold. Yes, the chiller is well insulated and is enclosed in a aluminum protective shell to give uniform support and strength.

Except the heat exchanger is underneath the super charger so that would be an entire engineering issue.

You have it backwards, on a air to air the intercooler is up front. On an air to water the heat exchanger is up front and the intercoolers are below the SC.

One other question, on the vette it has an expansion valve on the fire wall and not an orphice tube. How will you route the system in that regards. Thanks for the help!

There is an additional expansion valve at the chiller. And an additional orfice tube. Just think of how a dual AC system works in a van/SUV. You are correct on the backward terminology...and the chiller valve bypasses the heat exchanger up front when activated so the heat exchanger does not reduce the effectivness of the chiller.

How much weight would a system like this add to the car? Where is the planned mounting location?

[Mr. Wyndham]

I've often thought of cooling the charge with the air conditioner...this is incredible!!

I can't wait to see it in action on a Camaro!

Since you're adding more plumbing (and therefore volume) to the A/C system, though -- will it require a addition of some refrigerant to "fill up" the system?

What is the water temp coming back from the SC? The air coming into the front H/E isn't going to be 120 degrees, unless you're sitting at a stoplight. While the bottom of the H/E may be 12in above the road, it spans up a good deal from there. Your outside ambient temp will be pretty much what the H/E sees. Unless i'm mistaken this setup isn't big enough to handle the entire duty of cooling the water. It's meant as a add-on to supliment the SC's H/E. Anything cooler you add to the system will be an improvement. The main question will be, will it give enough benefit to offset the HP loss from running the AC.

I'm speaking of the H/E in the front of the car.

Entire system adds about 9 lbs. It mounts behind the bumper cover.

Yes, it takes more 134a as the OEM system volume is increased.

Never measured the return temp as I can't think of why one would need to. As for the capacity, an automotive AC system stock is enough to cool a average bedroom that is properly insulated. The average car is all metal and glass (turn off your AC on a hot day and in less than a minute it is hot as heck) and takes an immense amount of AC to cool. The cooling of the HE is a drop in the bucket. As a poster above stated, watch the youtube video...it takes less than 2 minutes to drop the intercooler coolant 20 plus degrees, and the hotter the outside air temp, the better the system cools (as much as a 30-40 degree drop!). This is why the inside cabin AC will still work fine along with the chiller.

Here is a picture of the chiller on a scale, less than 5.5 lbs. It is made of SS, the rest is all AL so very minimal weight:

Are you saying you add a valve to the water line to bypass the H/E?

Depending on the boost psi and ambient temp. will determine the water temp coming out of the intercoolers. Most LS motors with tvs systems will only make 7-9 psi so were not talking a lot of heat from the boost. The mustang guys are making 18-24psi using the KC and it is dropping the IAT2's down 30+ degrees. Thats alot!

The heat from the road may not equal 120 but it will be in between 90 and 120, probably around 100. I have never measured it obviously but you can feel the heat coming up from any hot asphaut or concrete. The point is that I am trying to keep my water temp between 50-70 degrees and 100+ blowing across the H/E will only warm it up. The guys on the corvette forum right now running the e-force are seeing 120-140 water temps so if you blow 100 degree across the H/E, even though its hot, its still cooler than 140. Problem is once you reach 130 the car starts to pull timing.

My plan is to move the battery to the trunk and in its place install a 3 gallon insulated tank and insulate all the hoses to and from. Once the a/c is runing for 5 minutes or so it will get the temps down to 50 degrees or so depending on how hot it is. With nearly 4 gallons of chilled water in the entire system it would take a lot to warm it up. You may get on it for 10-15 sec. and when you let off the compressor kicks back on and chills the water again.

The question about the hp loss is only about 6-7 which is minimal, and the compressor will kick off at WOT anyway. Also there is a freon called industrial 12a that is supposed to cool better than 134r and r12, and it is compatable with 134r systems. This will be my winter project so I will post pictures and results when I am finished. Thanks!

WOW! I'm learning a lot in this thread. Thanks for all the input everyone! The other product wasn't what I was thinking of exactly (it was Ford that I thought that was actually developing it) but that looks like a cool set-up too. Being this product is going to be purpose built for CAMARO, it has a lot more interest for me.

I'm hoping we'll see some more development information as time goes by. It'd be great to see some results of road testing and cool-down times, and effects of power draw on WOT engine operation, and whatever else anyone else can think of
