Twin Turbo Ls3

[RSX302]

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?

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.

I like how compact and efficient the water/air coolers are. (e.g.;ZR1) I was thinking of putting a small water tank and pump in the trunk and running the lines to the front. 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)
