Leaving the Thermostat out ???

[Micksan]

After a lot of head scratching and taging each cable I disconnected , I have reached the mother load>>The water Temp Sensor. BTW Had to modify a 19 mm wrench to get it out , an replaced.
Just about right next to it is the housing for the thermostat. Has anyone left this out. We are in a pretty warm climate . I have done it on a lot of old pickup trucks, and a 1100 Gold wing. Allows them to run cooler in the 100 ddegree heat.
That is the up side , now give me the bad side.

The thermostat is very important. It lets your engine run cooler. I know that sounds odd but it is true. I built a Pontiac 455 up to 675 hp and 750 lb ft. The guy putting the car back together said that he left out the thermostat for better cooling. Sounded great to me. The thing boiled over and blew up my 4 core aluminum rad. Went to the ebgine builder and he explained what happened to me this way.

The thermostat cycles keeping the engine temp constant. BUT it allows for more dwell time in the rad thus cooling the fluid to a lower temp. This then cools the engine. Without a thermostat the fluid will cycle so quickly that the radiator dwell time is insufficient to cool the fluid properly and thus will pickup more heat than it can disipate. Since then I have always run a higher temp (195) thermostat and never had overheating problems (did have them with a lower temp, 165 unit).

Concur with oakville... he explained it very well.
