Water to air intercoolers...

[EclipseGST]

I have yet to see a nice water to air intercooler that you can use on a daily driver. They are mainly for drag purposes so when used on the street they tend to heat soak easily.

A couple that I have seen use a chiller box that you can fill with ice and the water will run through it by using a electric water pump. Then it gets run through the intercooler in an attempt to cool down the charged air. When using this setup on the street its hard to keep enough ice in the chiller box so that the water stays cold.

I've heard of people using separate radiators for them but personally I would think that would heat soak just as much. There are many different opinions of these types of intercoolers, mine is stay away from it if the car is a daily driver. Good luck.
