PT Radiator Air Scoop

Gregg,

Check this web site, scroll down a little and look for the Hayden
High Performance Rapid Cool Radiator Mist System. $50 bucks. A couple
of these units with a few more nozzles would work. Mount it, wire it,
good to go. If there is no vacuum to pull it in you will need to spay
the water into the Rad some how.
