K, so without a thermostat, I'd be able to use a smaller radiator, since there would still be more flow, regardless of whether it's loading the water pump or not. Smaller radiator = less fluid to pump, which DOES partially unload the water pump, and less weight (granted, miniscule amount) that the engine has to propel when moving the vehicle, plus another measure of aero benefit.

Granted, all miniscule compared to leaving the t-stat in, but still gains to be had. On top of all that, no worrying about the Tstat failing closed. Not supposed to happen, but it does.
