Intercooler spray?

[sakigt]

Im sure the emissions coming from our vehicles is doing more harm than the IC spray...

But that is false logic and Id rather put a bag of ice on my IC before my run than buy a product that has dripped chemicals into animals eyes. Thanks for that info, Punch.

This Radiator Relief stuff sounds like Snake Oil. I understand that ColdFire is a chemical that has extremely high heat of vaporization (how much extra heat you need to add to a fluid to transition from liquid to gas). In order for this additive to heat up faster the specific heat of the fluid would have to be lower (holds less heat per unit volume which is bad for a coolant), and at the same time purports to lower the operating temperature (holding more heat per unit). If such a fluid existed, I am sure I would know about it. Fact is, water is an excellent coolant - high specific heat, high heat of vaporization, and decently high boiling point. Just needs glycol to prevent freezing and other additives for corrosion resistance. If your car never sees those kind of temps, you could run 90/10 water/glycol and change it once a year for better cooling performance.

Anyhow, Water Wetter is popular for racers (and sometimes required) because it isn't slippery like glycol (normal anti-freeze) when it gets spilled on the track. It works better than straight water by lowering the viscosity, which reduces the size of the bubbles that form from boiling inside the coolant passages. You can see this by adding a drop of dish detergent to a pan of boiling water (which Water Wetter is closely related to). The metal under the bubble gets hot in a hurry because there is no coolant to suck the heat away. Race engines are an extreme test for most coolant systems, and they usually operate very hot - so they need all the help they can get.
