How complicated is an air-water system? Do you have to cool the water off with ice or can it run on its own much like a standard cooling system?

...and do they have a pump to circulate the water?

Either way. Most drag only units are plumbed into a separate ice water reservoir (Coleman cooler) and use a circulating pump. They can also be plumbed into the cooling system, BUT this is obviously less effective cooling, and you will need to look at radiator size because you are going to need a LOT more heat rejection to keep everything cool.

How complicated? I guess it depends on the space available. Air/Air would be less if you don't need to hack/modify your front end to make it work. Originally Posted by PhillipM

Heat exchanger looks kinda like an A/C condenser if you place in front of the radiator. I think you can run a smaller coil with a 10" fan anywhere you can find space under the car?
I was also thinking--with the turbos, you don't need to have the pump running all the time while cruising. For the street, use a boost switch to turn on the pump (adj time delay off) and for the track use an override switch (Ice in the tank for a colder charge on dragstrip days)Ron DeRaad
