I built an air/water intercooler system for it that's incredibly effective - mainly because of the chilled water I use to run thru it. I pump the intercooler system's coolant thru the heater core and use the AC system to chill the water. The system includes a 2.5 gallon reservoir. Once all of the water in the system is chilled, it provides about a full minute's worth of cold water when in boost. The whole rest of the time you are driving it (not in boost) - it's chilling the water for the next time you nail the throttle. This water circulates continuously - cooling the intake charge and also the fuel rails. Both of these really help the throttle response - especially on hot days.

I also use the chilled water from the intercooler system to cool my fuel rails. That works great on the street since I'm generally running the AC system all the time anyway. For trips to the track I have a separate small radiator that I add into the loop of the system. This small radiator sits inside an ice chest full of ice and water. To connect it into the system I use some dry-break connectors. This allows me to hook the truck up to the extra radiator - chill all of the water in the system - then disconnect it and go race... all without spilling any water or dumping ice into anything. When I come back to the pits it only takes about 5 minutes and the system is back to about 40° and I'm ready for another pass. The tank and lines are insulated so it all stays cool while you wait in the staging lanes.
