Congrats on your new car and welcome,
All good advise on cooling your car, I didn't see if anybody mentioned "water wetter" since coolant is not legal in any class on track, water wetter is legal and does help to cool your motor. Also look inside of your radiator to make sure it's clean, if anybody put FL tap water in it, you might need to have it boiled or just replace it since they aren't that expensive, maybe with a turbo radiator if your racing in the summer months. I have always used distilled water, but now word on the street is to use RO??? Just don't use tap.
There are a few brands of water wetter, Amzoil, Redline etc... here is a couple that I just pulled up on line
