You shouldn't have any problems, especially if this is your first time out. I had no problems tracking my car in a few events last year, and it's an auto with no oil cooler and JB2.
However, as I was getting faster I noticed that the temps were creeping up. This year I am going to try Orb's advice above regarding the 30/70 mix with waterwetter in the cooling system. I did this in my previous car, a Miata, and it worked well, even with a supercharger and stock rad (the stocker is known to be too small for track use).
