Any of u guys out there after instal of a 180 stat, did your check engine light come on? I disconnected my battery and its off, should I expect it to come back on? Thanks
can this be fixed?cHeEzE said:it runs rich is because the ECT sensor will see that the engine is still cold and will keep dumping more fuel to warm up the engine.
The difference between 180 and 195 is almost 2 tenths to my car at the track.cHeEzE said:i see no power gains from doing this mod tho.
a cooler thermostat won't keep your engine cooler...it'll just take longer to warm up.SRT-4 Neon said:with my 180, i have no fuel enrichment problems, and the car is faster as OvenMan said (not due to HP or torque gains, but lower engine temps)

SRT-4 Neon said:no, but it will allow cooler air thru the radiator which helps to reduce the temp of the manifold thats right behind it. that leads to cooler air into the engine...and hence better performance.

except you forget...colder intake equals more dense air into the engine...so that means better torque and HP i guess...that would result in faster...Narcisse91 said:The only thing that makes your car faster is torque gain or weight lost. Lowering engine temps doesn't just make your car faster, it would've had to have gained some power.
Changing your thermostat doesn't allow cooler air through the radiator. Changing your thermostat allows coolant to flow through the engine at a lower temperature. The thermostat opens up at 180 degrees, allowing coolant that has been cooled by the radiator to flow into the engine. When the engine temp drops low enough, the thermostat closes, and coolant stops flowing through the engine. Some coolant stays in the radiator and cools down, while some stays in the engine and heats up. When the coolant temp in the engine reaches 180 degrees again, the thermostat opens back up and coolant flows.
Cars with magic things going on are pretty cool.
Dont forget better timing at lower temps = more hp. I have a dyno graph that proves a 180 thermo helps alot i mean ALOT. at baseline i dynoed 298 whp with 160-170 temps. at normal temps 200+- i dynoed 265 whp. This was proven twice. not to mention on the freeway when your running 180 and hit it... oh ya, big difference. just my o2 tho. take for what its worth. billySRT-4 Neon said:except you forget...colder intake equals more dense air into the engine...so that means better torque and HP i guess...that would result in faster...
look do it or don't do it people. its your choice. everyone i know who races makes the 15 degree colder thermostat swap. it was the first thing I ever did to my 72 comet. I didn't invent the idea, i've just seen it work. Its not magic, its easy physics.
