It's common for people not running a thermostat to run a restrictor in it's place to keep the coolant running at the intended rate. Coolant running faster than it should cannot take on heat as effectively as slower moving coolant. I first heard about people doing this back in the late 80s/early 90s in the muscle car community, but I believe it was actually a Smokey Yunick discovery. Never tried it myself since I always use a thermostat on the street, and I think it is likely related to sustained high rpm operation like you'd only get under race conditions.
