How a Wild Engine Keeps its Cool

To attain its bonkers performance at the drag strip (0-60 mph in 2.3 seconds; quarter-mile in 9.65 seconds), the 2018 Dodge Challenger Demon needed more than just a supercharged 6.2-liter V-8; it needed a new way to keep that massive powerplant cool so it could maintain its full 840 horsepower potential over successive runs. Thus, an innovation Dodge is calling the “SRT Power Chiller.” During and after high speed runs, it diverts the refrigerant from the air conditioner (yes, the one keeping the cabin cool) to a unit near the coolant pump, where it’s used to further bring down the temp of charge-air coolant. The double-chilled coolant then flows to the supercharger, keeping the Demon’s heart from overheating.
