Default Anyone try a 190 Stat in their '11?

I know Stant makes a 190 Thermostat. I know a lot of guys with other years love their 180's but I've read that the 11+ is no good with a 180 stat. Engineers chose 203 for some reason, and I'm sure it is not simply because of emissions. Anyway, just wondering if anyone has tried running a 190 and if there are any good or bad things about it, or if it is even a good idea.

I have a 2011 and run the 180 with no issues whatsoever.

Same here, had mine on for over a year with no problems at all. What makes you so sure that they didn't run the 203 for emission purposes?

It is soley because of emissions, nothing else...it is controlled in Calif by themselves, along with the enviormental Protection Agency through out the states, and Texas Railroads in Texas for LPG fueled vehicles. No disrepect to anyone here, but engineers learn performance tips from mopar fanatics like Don Garlits, Ed Hamburger Keith Black, Russ Flagle from Indy, Ray Barton, Bill Mitchell and the list goes on forever. They do not know how to build a high performance vehicle without assembling the likes of Ford Racing teams, Mopar Performance, Direct Connection (use to be Ed Hamburger) and GM performance teams. Everyone of the specialist on these teams had something to do with racing, that's where they started and that's why they were hired. To get the most performance at the same time be able to burn off the extra fuel from high performance or gass guzzling vehicles. They have to sacrafice HP to burn off unspent fuel and emissions with these 200 plus degree thermostats. There are people who will argue this on here because they do not know anything about what makes an engine tick. They may know thermal physics or solutions but they do not know the inside of a combustion chamber from a hole in the ground.

I'm sure that emissions do have something to do with. A hotter engine generally runs more efficiently than a colder engine. Not to mention that things like oil, trans fluid, diff fluid, p/s fluid, etc are designed to run hotter and there is less drag=higher efficiency when driving. I won't argue with the idea that you might be able to pull more hp out of the engine by keeping it cooler with more timing etc, but one thing to remember is that the engine was designed to run at the temps that the engineers have it running at. There are a lot of hemi's out on the road with tons of miles on them running very reliably with the factory setups.

That being said, I figured that the 190deg is a good compromise between 203 and 180. I will allow the engine to run cooler but still allow for everything to heat up and run as it should. I don't know what oil temps look like in these engines with the 180 stats, but you want the oil to be hot enough to burn off contaminates and also be hot enough to run efficiently.

So I can't speak for power differences between the stats, but I can tell you what I've observed with the Stant 190 part # 48799.

Made in the USA
Looks nearly identical to the factory stat. The motor looks the same, the piston looks the same. The rubber piston sealing are is identical. Has the same notches as the OEM. Many of the markings are very similar. I would not be surprised at all of Stant is the OEM supplier.
Gasket looks identical except it is black instead of orange. (pos nitrile vs silicone maybe?)
Same 63mm, fits perfect.
Same giggle valve as oem
Maintains pretty much 190deg while maintaining speed. Sometimes it will hit 192 before doing its drop down count, but pretty much works just as the OEM but at a lower level.
Power and acceleration along with the same DS Trinity tune Ive been running does feel a little bit stronger than it did with the 203 stat. I don't have specific numbers but it feels like the power response is better.
I have not had any LT knock counts, and ST counts are down compared to before.

Engine warms up just as fast as it did before, everything is working just as it was but the coolant temps are down.

So far I am happy with it. A little piece of mind knowing that the engine is a little cooler and that I'm not getting any warm up codes or anything like that.

I would say this is a good mod/choice for anyone who may be on the fence about changing out to a 180.

I put a 180 in my 09 truck as soon as I got it. Well as soon as I found one, it took a while for that. But I had no tuner and I didn't install my tuner the first year so I ran it for a while without it. I never had any problems or codes pop up and it's been to the dealer with transmission warranty work without voiding anything.

I've been running the 190 for a couple of months now. If there is a difference in mpg, it would be very hard for me to tell. My fuel economy has been sent pretty consistsnt and hasn't had any notifiable change since switching t-stats. I've read some people state that it has decreased slightly when using a 180 stat, but aside from my own results, I'm not sure if there are many posts about the 190. So far I'm happy with it
