WEAPON-X: Boost Freeze Chiller for ATS-V, Camaro, Corvette, and CTS-V launches 9/4/18!

Posted by Ben Herndon on


With a well known name for the best heat exchangers and ancillary cooling mods on the market, we have been working on the next step in cooling for the past year and a half and after testing various combinations, we are finally ready to release our Boost Freeze Chiller! We have developed a complete plug and play system allowing you to tie into your OEM air conditioning system! This is the very first chiller system even available for the gen 6 Camaros, C7 Corvettes, CTS V gen 3s, and the ATS V and we also have the previous gens covered too ;) While this technology is not new, unfortunately to date, chiller kits have always been surrounded by mixed reviews from poorly designed kits with vastly incorrectly sized heat exchanger units, that required the OEM lines and wiring to be cut, brazed, welded, soldered, etc which means you needed someone that specializes in the AC field, and train-wreck forum threads between competing manufacturers bickering, accusations of them copying each other, and on and on. It was apparent that most of these guys were copying someone else's kit as in the end, a lot of consumers couldn't get their kits to work properly and received little support after, resulting in more bad PR for the chiller concept. However, simply put: the proven concept WORKS AMAZINGLY WELL when done properly! To prove this from a neutral source, the highly heralded Dodge Demon has a chiller from the factory, yes factory... we were shocked to see this!

How it works?
A chiller uses the OEM air conditioning system to reach freezing temperatures in the supercharger heat exchanger coolant to remove MORE heat from the compressed boosted air entering the engine, making it denser, allowing for MORE timing, and thus MORE POWER!!!  Now a commonly understood principle is that the cars that run with the AC on lose lots of power during wide open throttle (WOT) for a few reasons, 1 the AMP draw is high, 2 it floods heat into the radiator from the AC hx, and 3 the older units wouldn't destroke themselves when they see this. AC compressors have continued to improve and the one on the LT cars is impressive. Most cars will shut the AC off during WOT for the aforementioned reasons; however, the new ones will actually reduce the stroke on them, not really consuming much power at all. In our testing on an 850whp LT4 Whipple car, we only observed about 20 LB FT of torque down low and and less than 10 WHP up top!

The Benefits
Our kit has a lot of bells and whistles as well and it's plug and play with custom billet fittings we machine in-house. The cabin air conditioning on our kit remains unaffected and still allows you to remain cool inside while your supercharger gets frost bitten too as it includes a cabin diverter valve so you can leave it in 50/50 mode splitting the AC, or put it into 100% HX mode so the supercharger coolant gets all of the BTU capacity to reduce the fluid temps even quicker. The kit also includes a thermostatically controlled valve that bypasses the heat exchanger(s) too because there comes a point when the coolant is below ambient temperature and running it through the aluminum heat exchanger will actually heat up the fluid. Lastly, we an optional have a Bluetooth display that you can adjust your temps and valve with while monitoring just how cold it gets. Consequently, our SPI Kit can also control the Chiller as well. ;)

One of the most unique features of our kit is we have also developed a thermal cooling cell, which needs no ice. It serves as two purposes, extra fluid capacity and extra BTU capacity. As the chilled fluid passes through it after the chiller, it charges the cell and once the fluid starts to heat up from the engine heat transfers that occur over the course of a run where the AC system is taxed by the external heat sources, the fluid is then chilled again by the cell as well to help with longer periods of time. This really helps the entire system, especially for in times of higher ambient air, longer runs, and other adverse conditions. A lot of guys have asked about the possibility of running this in road racing, and I didn't want to get into it before we had more product development; however, I do think it is possible on the LT cars. The main thing that is needed is to insulate all of the lines, fittings, etc and be able to keep the condensation off of the track. I am very interested in working with a road racer who is savvy when it comes to data logging and being able to provide the necessary data in return. The kit

System features:

  • Plug and Play hardware for a hassle free installation

  • 100% reversible

  • Requires no tuning changes; however, the PCM calibration can be modified to achieve more power when temps are under a certain threshold (IAT Advance)

  • Insulated chiller unit

  • OEM quality hardware, lines, and fittings

  • Thermostat controlled heat exchanger bypass when temperatures are below ambient

  • Cabin diverter for race mode to channel ALL of the refrigerant to the chiller

  • Bluetooth controller for Temperature monitor and custom programming settings

  • Thermal Cooling cell to store extra BTU capacity

  • Optional WXM Track Attack Heat Exchanger upgrade further more natural cooling

Here is an older version of our Chiller on my 1150whp Gen 6 ZL1. This car is a MONSTER making 1100lbft of torque by 4200 RPMs with an 85mm rear mount turbo pushing through the stock Eaton 1.7L LT4 ported supercharger. It has been an interesting project for sure, we are not spinning the blower crazily at all with a 25% increase, but it's making 14 PSI on the 427 cubic inch LT4 engine as we have MAP sensors at various positions on the kit to log. 14 PSI with only a 25% increase on a 427 with our big valve heads is amazing. All together, the compound boost was around 24 PSI. The air temps coming out of this air to water box with 14 PSI from the turbo, but only 10 PSI after running the length of the car and going through the air to water box was just 46* as it entered the supercharger! So, the more dense air entering the supercharger along with the pushing of that air from the turbo greatly reduced the parasitic loss of the supercharger making the entire system more efficient.

On a test hit I made, the Air Temp post supercharger lobes was 99* at 142 MPH and having gone through 7 gears (10 speed auto). That is astounding at that power level!!
