I purchased a used cas v1 today, guy said it was a couple years old. I know this is a big IC, do you have any cooling problems? I have a cas aluminum radiator, stock fan. I have an esp front mount now, no cooling problems. I know this IC was designed for faster cars, but I plan to run 10.90. It couldn't possibly slow me down, could it? Couldn't pass up the deal. Thanks for your time!
