It’s essentially a killer chiller setup. You can buy kits for most supercharger cars to convert them to that. Technically you can run it on any setup but works the best on sc cars by cooling the upper inter cooler air charge right before the intake manifold if I understand the system right.
The Freon system is tied into and plumbing is routed to cool the central heat exchanger via a port tap. Works very well.
When you turn on the ac, it cools the cab and the engine.
I’ve always thought manufactures should setup most cars to do this regardless of engine setup because when you run the ac it’s usually very hot outside. It’s common to overheat an engine running accessories in summer. I’m sure they don’t do it to conserve fuel consumption, but as an engineer, I would personally want to engineer a load or demand switch that opened when engine coolant temp crossed 225° or cylinder temp touched xyz°.
Who cares about 1mpg when it’s 100° and your car is running hot? Just put a 20% larger Freon system to account for he expected summer demand when applicable.
You could then put a window switch or digital control for the function in the cabin or have it kick on when the car is in sport or race mode.
But, I’m a plebeian so what do I know.
@Tob whats your thoughts on all this conjecture and bench engineering I’m dreaming up? Should I keep my day job or start a side business with retrofits that can talk to the ecu of most performance cars, or have a small stand alone? Sort of a killer chiller 2.0 now with tech haha
Running the AC causes extra heat at the AC condenser; radiator looking deal in front of the engine coolant radiator. In areas with hot climates and mountain passes, you’ll actually see signs telling you to turn the AC off. This is also why turning the AC on results in either a second fan or the main fan bumping to high speed.
