Running without a thermostat ok?
After installing the 195 it never got over 180 on the gauge. In a smaller engine the thermostat will probably take longer to cycle as it takes longer to heat the water in the block. Letting the water pause while in the radiator makes a big difference in how much heat is transferred.
If
any of this is true, the laws of thermodynamics do not apply to your car.
I suggest you start filing patents and looking for grant money to do research, because every physics and thermodynamics text written in the last couple hundred years must be wrong.
Meanwhile, you can remove your radiator entirely and just connect your top and bottom hoses. If the temp is never above 180, and the thermostat is a 195, it
never opens. Where is the sending unit for the temp gauge? Think about it for a second...
Finally-
The problem with thinking water needs to spend more time in the radiator is that it must spend more time in the engine for that to happen. It's a
closed system. If the radiator can dissipate more heat than the engine can put in (which it can if your cooling system works!!!), you need to circulate MORE water, not less. Which is why high volume water pumps work better than standard ones for modified engines which make more heat. You want more water to move through the radiator, not stay there longer.
Yes, you need a thermostat. Your car will get just as hot without one,
and it will also take longer to warm up, which will trash your engine.
