I did a test. I unhooked the coolant temp probe on the front of the engine. drove the car till warm. Very interesting, coolant temp quit, engine temp quit, AND oil temp all quit. I do know the oil temp has it's own probe, so why did they all quit. Must be connected electrically some how. I am not sure where the engine temp probe is.

I'm just saying that if I'm running 220*+ on the gauge, the car doesn't seem to run as well. The supercharger is bolted to the engine and the hotter it gets the worse it performs. My car came with a 186* thermostat. As nearly as I can tell, GM doesn't sell that one anymore, so I'm using the next best thing at 174*. In 95* ambient temps it usually runs high 180s to low 200s depending on whether I'm at highway speeds or in slow traffic.
