Screaminjoe, what kid of ride do you have there? You say 6 speed roadster, is it a SRT6 you put a 6 speed in or a regular roadster you put a supercharger on? Cool idea though, I had already read that thread. I had thought of changing out my antifreeze out with some stuff I seen in Hot Rod magazine called purple something, it was suppose to make your engine run like 20 or 30% cooler than regular antifreeze.
