My car still has not been shipped yet so I have not been able to check out the set up on the intercooler, but would it be possible to add a second heat exchanger and maybe a sprayer along with it?

AND... I have a question which I could answer if I had my car already, but since I dont - the question is... Is the coolant for the intercooler the same that is running through the engine. If so, then it would be picking up heat from the engine and be less efficient than if it were not routed through the engine.

If it is running through the engine I'm sure that it would be very easy to re-route or bypass the coolant from entering the engine.
