expensive

Easiest way to keep a 600hp+ monster cool at idle. I am not sure my car will overheat yet as the work isn't done, but I want to be proactive. Want my car cool in 80 degree humid weather. Any tricks or expensive overkill parts?

Unfortunately, this is not the start of a joke thread! While driving around the other day, I developed a pretty nasty mechanical knocking that started low and progressed much louder over just a couple of miles. Engine sputters and lurches, but I have not lost fluids or noticeably blown anything...
