Unfortunately once that water's hot, its hard to get the heat out of it by transfering it into the air.

Stock w/a IC systems (syclone came with em) work fairly well, especially to solve charge pipe plubming issues. We just use a 2nd radiator (cche) to cool off the water.

They shine for drag racing because its easy to make them ice cold. Where they loose out is the hotlap, daily driving arena. Choose what you want.

Either way, you cant get colder then ambient w/o an exhaustable cooling source. (with exception of an 'intracooler' that uses w/a and cools the water with the a/c system's compressed freon)
