A pretty common question I have been getting is about the ice tank. The ice tank is actually the supercharger water reservoir. The lines from the supercharger run back to a tank in the trunk. It's about 20ft of hose so it helps the water to cool a lot more than the small tank that comes with the kit. I run just water most of the time and it keeps the supercharger cool without using meth. The tank has a drain under the car so you can add ice if you are at the track or doing any hard driving to keep it even colder.
