I have the opertunity to get a charge cooler to put on my sapph, remote boot mounted tank etc.

As I've got a RS500 size I/C, is it worth getting?

Before you ask I don't have an ACT gauge, but is a 500 I/C good enough on its own or is the CC just going to be overkill?

CC's don't seem to get used much on cossies, is it due to the price?
