Car is a cruiser and track car. My current setup is air to air. Last time at the track, noticed my intercooler (4x12x18 with fans) was heat soaked by the middle of the run and my charge temp went up more than 80 degrees.
I'm considering switching over to air to water with a reservoir for cool water. Instead of the water getting cooled by a typical heat exchanger, it's cooled by an A/C evaporator in the water reservoir.
I think I can get the charge temps down to the 50s even on hot days that way. Maybe even can precool water enough to leave the A/C compressor off during a run, or maybe just have it turn off at the top half of the track.
Already have the A/C compressor installed for two years, may as well get some use out of it.
Lower charge temps will also result in more dense charge, more power and less chance of detonation.
So I have been planning on this for awhile. Killer chiller is the actual product. It is super over priced any way. I d recommend looking in to a plate beer wort chiller on ebay. I'm gonna use a big one. A mid 90 to late 90s peterbilt 379 bunk expansion valve would be best. I believe the external evaporator is a better plan due to if there needs anything replaced like a evaporator or expansion valve then it can be replaced individually instead of the whole tank. Yes this works really well.

Hey guys, just saw this, look for a "jockey box" chiller kit,
a "cold plate" for a jockey box chiller.
I worked in the craft beer industry for a long time and we used these things for chilling beer when we poured at festivals and no refrigeration was available. Coupled with ice, you get col' beer.
Most tracks won't let you run the AC while at the track because of the water that drips down when it's on and as mentioned above the car will run slower with the AC engaged. You are much better off using an oversized reservoir and filling it with ice.
The ac compressor will shut off when it hits a certain rpm so there are minimal "losses". Everyone whose posted about a killer chiller loves it. 40 degree IATs in the middle of summer.

They do work well for the street but not nearly as well as ice at the track. You can easily make your own by using the parts from any mini van/suv that has both front and rear air.

No doubt but it's awfully nice on back to back stuff without having to worry about adding ice.

I'll look into what might work. Why not just shove an evaporator from any car A/C system into the water reservoir?

I've worked with Ice before. It's way more complicated. This car is cruiser that is driven to track, It doesn't even get a tire change. It's not going to see ice.
A/C compressor will rob power. But will a cold dense charge and higher boost provide more power than the A/C compressor uses? I vote Yes!! Also once the reservoir is cooled, A/C compressor can be turned off.

No drips. Air is not condensing. The evaporator is already in the water. The carge pipe and the cool tank and intake manifold may get some external condensation, but that is no different than condesation from an Ice box.

Right on. Most of the time, the hood doesn't even get opened at the track.
Just sitting there waiting to be used.
There should be lots of space the the air to water and reservoir where the Intercooler used to be.
chiller works good, most of them are marketed toward oem PD blower applications
I use an interchiller with about 10 gallons of antifreeze (water will freeze) through a shearer fab hi ram cooler, a lot more surface area than supercharger bricks and there is a ton of heat load that comes off the condenser
it uses a heat exchanger for refrigerant to coolant , all the ac lines stay under the hood. 16an braided lines front to back dont condensate, the fittings will.
in mine (yukon) has a smaller radiator and different fans, i cant reject the heat fast enough to get it any colder than about 35*, i can add refrigerant and put external fan on the condenser or spray a little water on it and it will chill down into the teens but with hood closed, not moving, all that heat just pours onto the radiator and ECT starts to rise.
at track i would just pop hood and leave it running, fans on, no tstat, electric pump and fans. with 10 gallons back to back runs arent a problem...if it does manage to heat up all 10 gallons it takes about 20-30min to chill the entire circuit back down (including intercooler than sits on engine) with an intercooler away from the engine it would prob take less
went back to larger radiator and oem fans...havent got to drive it much lately but it already will sit and idle without any problems
It still gets condensation from around the tank and ac lines due to them cooling the air around them and causing condensation. I built a pan under my wort chiller and tank to store the condensation and it only drains it out when a valve is opened. I agree running compressor at high rpm is stupid but If you run a 15 gallon tank and use the ac to precgill the water to 40 to 45 degrees then a 15 gallon tank should give tou a few quarter miles worth if time between it recalling the water.

First, The AC will rob quite a bit of power under hard acceleration, I heard 30hp but much less while cruising. Also most Compressors are designed to run under 6,000rpms. That's less than most people want to turn at the track.
Second, I guessed it was going to split the AC between the cabin and chiller. I wouldn't want to give up AC in my truck just to cool a chiller while at the track.

Adding 150lbs of weight for the full reservoir and another 10lbs for the pump/lines/fittings just doesn't make sense to me, There has to be a better way to keep the IAT lower.
I'm mounting my tank in the trunk area. I'm not a huge fan of the weight but if I put it over or behing the rear wheels it will help traction. Before anyone asks I running the lines through the passengers compartment in my console to help keep them as cool as possible and them throught he firewall to the air to water. Haven't decided on a tick intercooler in the intake or a big external a2w.
I had a mustang with the killer chiller on a pd blower and it really didn't effect the ac in anyway. I had already upgraded the cooling system with a taurus fan so that could be why I never really noticed.
Now that i look at the layout of my radiator and intercooler, with a chiller setup, I'd be better off with the radiator and condenser in front where the intercooler used to be, and the Air/water where the radiator used to be. That would also make my charge pipes shorter. Cleaner fit and better cooling of the condenser.
I've heard R/V coolant works great. I'm thinking about a 5 gallon tank for starters. That should only add 35 lbs. I already have the weight of the compressor in the car. My car's computers can automatically manage the A/C and shut it off at any RPM or driving mode.
I've been lazy and not installed the A/C in the cabin yet. I've been driving the car for thousands of miles in the last few years and have not missed the A/C. I'm probably not going to put it in the cabin.
I think there's a missed opportunity with these interchiller applications... A number of those ad videos from killer chiller and others often show them just cruising down the road talking about how cold the IATs are. I don't give two ***** about the IATs at part load..I'd rather keep the chilled fluid stored until its actually required in boost. That also allows it to chill even further. I bought some old school vacuum actuated heater core valves with the intent of using them to make this happen but haven't got around to it. They'd essentially block the flow from the super chilled reservoir until you're near WOT, MAP near baro where they flood the IC with the chilled fluid. Someone should try it...
I was going to do something like this cause I'm using a Craig Davies pump that can be operated by pulse width modulation. Slower pump speed at low load and then full flow at high speed. That way it keeps the intercooler chilled all the time but isn't using all the fluid up all the time.
