Yea mgcook I would look into you cooling system. Make sure your fans are coming on, the t-stat is good and your radiator isnt scaled up and/or excessive damage to the fins. But yea as I said...if you dont overheat or get too hot in the situations mentioned above you wont have any issues at the track. You wont be idling excessively so you should have good coolanty flow and with the speed comes good airflow across the radiator so its not hard to keep things cool....as long as you dont have any issues with the cooling now. But I guess the other guys chimed in with proper amounts of water wetter if you do go that route.
