I like this. The motor makes much more power when it is on the cold side and living near Fort Myers it gets HOT here to where the fan does not keep up. We get go fast mods and skit some of the obvious. I'll try the 4 small holes in my T-stat and my question is what happens to the computer control of the fan or is it controlled separetly? I don't think I would mind the fan in high speed at all times as then hearing is poor and the car seems so much quicker when it is cooler. maybe 170* would be optimum.
