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.

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. Quote:
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?

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? |

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

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

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:

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
