There may be something to gain with a larger resivior for the intercooler if it is the one that has the large fuel cell styled cap. The trick is that you can pack it with ice but what that will get you at the track and how long it stays cold may not be all that practical. Some of the heat exchangers may provide a larger degree of cooling but only as long as you have air flow through it. I do recall seeing a dual fan kit for the heat exchanger somewhere.

It may also depend on what fluids you use. For track use (drag stirp or circuit) water is the only effecient means to effectively get a good heat transfer. Coolant on the other hand only prevents boiling and or freezing and the water in the mix is the heat transfer medium and not the coolant or antifreeze. Having reliable air flow through the heat exchanger or radiator is the key ingrediant and how large the core is and if it is designed right, the heat transfer will be more efficient. The other issue is ambient air temperature and the inlet air temperature. If you are drawing in engine heated air that will just compound the issue.

If you wish to reduce inlet temperatures there is always methanol injection.

I would agree with Dave on this one. Inless you are willing to remove the passenger seat and replace that with an industrial sized heat exchanger the effects of the heated air and the stock heat exchanger/intercooler will not be all that dramatic. I wonder if an air to air or water to air precooler would work along with the intercooler or would that just be added weight?
