Running without a thermostat ok?

I love these know it all engineer types and wanna be engineer types. Heat transfer is not instantaneous although non ferrous metals do perform better than iron. Now figure the difference in surface area and conductivity between the inside if the block and the inside of the tubes in a 4 core brass or aluminum radiator. Apply the wrapping function of Pi to the diameter of the dohicky. The thermostat does not have to open that fast to generate a rapid flow. The same thermodynamics that make the thermostat somewhat sluggish are also why the 1970s era temp sending unit does not respond as fast as a thermistor. The location of the sending unit in relation to the sender will also give a somewhat false reading. So you seem to be saying that a skillet should instantly fry an egg as soon as you put it on the stove.. or does it take a while to "transfer" the friggin heat?

The problem being solved was for a vehicle not in motion. If the same amount of air went through the radiator at a stop as it did in motion a much smaller radiator would be perfect and all the rules of a closed system and constants would apply.
