Draco-REX Posted September 3, 2007 Report Share Posted September 3, 2007 This is how I understand the intercooler sprays: Water: Good to reduce heat-soak, or to provde cooling if there isn't much air going over the IC. However, it'll never get the IC much lower than ambient. Adding some alcohol to the water can get you a couple degrees lower, but not much. More effective on TMICs rather than FMICs because of gravity. CO2/Nitrous: Capable of sub-zero temperatures. However the sudden drop can cause metal fatigue, and can cause condensation that becomes ice. In that case, the ice can block airflow through the IC. As for CO2 or N2O, some of it wll be sucked into the intake, and performance wise, N20 is better for your engine to ingest than CO2. Quote Link to comment Share on other sites More sharing options...
