check the search feature and see if you can find an older thread on water sprays. theres an article that julian edgar (aka fast fours and rotarys) wrote about a kit you can buy that sprays automatically when your car NEEDS it. when you give the car a burst of wot, it DOESNT need it- the cooler is quite cool, but heats up quick shortly AFTER a hard burst. this article is really interesting, and they tested average temps through a run of various speeds/accell. etc, and this kit keeps temps stable, by spraying WHEN YOU WOULDNT- in fact it seems to spray at odd times, but when the cooler needs it. anyways, do a search, its a great read.
