im lookimg at running a 22x19 triple flow afco rad on my 1500hp hemi turbo setup and street car with drag week on the list to do.
the more you can get air across the fluid to cool it the smaller the rad can be physically. the radiator is capable of 600hp worth of cooling. which is about what my engine will make n/a and street driving without boost. the rad is around 200 bucks. have to have it modified for the triple flow but that doesnt cost hardly anything at all to the cost., but i dont have the part number in front of me.
