well i have a water to air system on my dart. i made a 7 gallon tank, the innercooler rated for 1200 hp., i converted a ford f-450 trans cooler into a heat exchanger that i mounted under the trunk where the gas tank was. it also has daul spal fans on it. i never have to add water and i only use ice when i really want to beat on it (i.e. the track or dyno..). i drive the car on the street when its 30deg or 110deg outside! it always runs the same. i will try to post some pics later if you want.
