Here is one of our test vehicles, a 2017 LT4 powered Camaro ZL1 with a 15% pulley, headers, etc and this compares the stock heat exchanger system to the chiller with both pulls being from a similar start as you can see the engine coolant is actually a few degrees cooler on the OEM heat exchanger pull vs the chiller pull. The chiller system was actually decreasing the Manifold Air Temps (teal blue line in the top bracket) prior to the pull, limited the total heat entered into the system, and then immediately started bringing it right back down! The OEM hx run had knock and higher boost; however, the chiller with no tuning changes allowed for approx 20whp more with less boost due to the dense air!
