Ls1 which thermostat

Lower Temperature Thermostats:. Thermostats that are engineered to open at lower temperatures are suited for more hostile environments and performance builds.

If you're located in area that is exposed to constant hot weather, these thermostats will allow coolant to begin flowing through the engine sooner, keeping it cooler for longer. As for performance engines, given the amount of heat they generate, a cooler thermostat will prolong heat soak which equates to higher horsepower gains. Even greater results are possible if the fan enable temps are adjusted accordingly.

It's called aggregate heat. Or fucking magic How do you control your fans.. Either through a tune. Or a fan switch. Check this out and see if it helps. What happens when you completly remove the thomastat?

Your engine will run in closed loop mode or a longer period than you want. Your motor needs to be in open loop and at op temp to perform optimum I've seen dynos posted that showed HP gains changing thermostat temps, depending on the buildup and the heat ranges. Less heat makes more HP. Most engine sensors function at degrees, and the computer ignores them until the engine reaches that temp.

A degree thermostat allows the sensors to work, and will open further at say degrees than a will. The hotter the coolant gets, the more the thermostat opens, allowing more volume of water to pass to the radiator.

Thermostats aren't just open or closed. They open according to the water temp. A would not fully open until about A would not open fully until about There is a gain when changing the thermostat alone, but to maximize it around town you have to reprogram the cooling fans to kick on at a lower temp too.

It all adds up at the rear wheels, like porting or anything else. Hey jag, Excellent explanation I now have a much better understanding of the benefits of a lower temp tstat and will probably install one soon. Same here.. I guess I understood it that they were either open or closed as well A word of caution I just read on the century performance website about low temp tstats. This permits the engine to operate at a higher temperature, which allows the cooling system to operate at its best efficiency and to reduce engine emissions.

On performance applications it is sometimes effective to go to a lower temperature rated thermostat so as to compensate for the added power output from the engine modifications. But, you must be very careful when using lower thermostat ratings on computer-controlled engine applications.

Because the computer relies on pre-programmed variables that are calculated by engine coolant temperatures as one of the variables, using a lower temperature thermostat without corresponding modifications to computer programming can cause problems. Hense a tune to get the fans running right at the same time. Most people miss understand a thermostat The only purpose basically is to warm up the cyl.

It's pretty funny I live in Phx. The problem is Most of the time with a the stat Never shuts so it is constantly circulating. I thought it was ass backwards for a long time too. If your not changing the fan settings also your not doing much at all like others have said. Thats my 2 cents. Page 1 of 2 1 2 Last Jump to page:.
