luxury of 90 minutes between runs, and that it's tough for a sportsman racer to keep the engine cool during round-robin eliminations. That's just another reason to have an effective cooling system and to refrain from putting unnecessary heat in the engine by warming it up. Once the water temperature reaches a certain point, the cooling system can be overwhelmed. It's like sitting in a traffic jam and watching the needle on your street car's temperature gauge steadily climb. When it reaches the critical point, the cooling system loses its ability to control the temperature. The result is a toasted engine. I've watched racers warm up their engines and then turn off the electric pump and fan to keep heat in the motor. My advice is to leave the pump and fan running to pull heat out of the cylinder heads, which need to be cool. You won't pull much heat out of the oil because it's sitting in the sump of the oil pan. My recommendations to sportsman racers on surviving the long, hot summer are to use synthetic oil and run your engine as cool as you can.
