Should you run a car without a thermostat?

If your gonna run without a thermostat you need to either put in a big washer to restrict flow or "gut" the thermostat by removing the spring and guts and put the gutted thermostat back in to restrict flow. The water can't cool your motor very well if it moves too fast through the system. All of my Destruction Derby cars get this treatment, as a failed thermostat will stop flow completely.
