Actually, there is a little bit to it because I had a summit rad rated at 350-400hp, and I couldn't keep the car cool no matter what I did. I called BeCool and order a new rad rated at or above 700hp, and I didn't change anything else and it did the trick. In fact, a lot of the time I can run just one of the fans instead of both now. Engine doesn't get above 190* with the new Rad
