2014 Ford Flex Ecoboost Stock Thermostat is 180 degrees

I just looked at the thermostat on my new Flex that was built in December. These are the markings on it.

Motorcraft
USA
54mm
180 F
1X4E-8575-FC  followed by the number 2 in a circle

I really don't see the point of a 170 degree thermostat. Did earlier cars come with a 192 thermostat?

If your refer to modded stat being 170f they are 160F.

I believe all the info on the cooler plugs... but I live in Phoenix... high daily temps are commonly 100-120 degrees.  That said, if my t-stat opens 10 or 20 degrees cooler does that help more that a "first run" situation.  If you wanted it to remain cooler wouldn't it take a beefed up radiator fan?

Reischeperformance.com sells a 170 thermostat, and they market it as being better than a 160. They claim their 170 thermostat keeps engine temps around mid 180's. I know from datalogs with my 180 thermostat that temps never go over 195.

I don't see the point of dropping coolant temps another 10 degrees. The twin turbo BMW's at the track are hitting over 230 coolant temps, and they would definitely benefit from lower coolant temps. I don't see how dropping coolant temps from 195 to 185 is going to make any more power on pump gas. I wouldn't want to run a tune that was so close to the ragged edge that the extra 10 degrees would cause detonation. To each their own, and I have no data to support my opinion.
