opinions needed on this idea

Well, JimHarvard, I guess my engineering training doesn't permit me to agree with you. While it is correct to say engines run better, when cool, there is an optimum point beyond which being too cold hurts performance. Todays modern cooling systems use the thermostat to throttle the flow of the coolant to extract heat from the engine. Its been proven many times that flow without a thermostat prevents the flow of coolant from removing heat from the engine because the coolant moves too fast to absorb the heat. So I respectfully disagree with JimHarvard regarding cooling. Excessive heat will rob an engine of performance as will a cold engine. I've found over the years with todays engines, pressure radiators and coolants operating temperatures from 195F to 220F work just fine. Just my opinion.
