Well in our race car we run straight water running a chevy 350 running on alcohol and it was put on the dyno last year at over 600 horsepower and we even run tape on the rad and we never overheat and this stuff says "EVANS NPG+Ö COOLING is a new technology, a system initially developed for cooling race engines to reliably increase power" now my thought is the reason that race cars run tape on the rads is because more power with a hotter engine but not overheated engine so how does this help let me know <img src="/forums/images/graemlins/kewl.gif" alt="" /> in case i am way off base on this
