The OBDII scanner confirmed the tems displayed by the gauge. I have a tighter than stock mesh on the front facia that I will remove tonight as well.
Wow! You do know that the addition of a simple air dam to a car can increase cooling efficiency around 20% or more on some cars. If GM actually spends the money on an air dam and claims 20-40% increases in cooling efficiency then you know it must be necessary.
Holy crap! I know what I'm doing tonight.

Not trying to be an a-hole but:
Air dams are only in place to create turbulence under the car right before the radiator/ac condenser area. The turbulence screws up the smooth flow of air under the car and causes it to push a little pressure upwards, in effect forcing more air into the radiator since Air, as all things in nature takes the path of least resistance.
Therefore, more turbulence and higher pressure equals wind resistance...especially since it is forced through the cooling fins of a radiator... another restriction.
All that equals more energy required, albeit small amounts. I do not see how gas mileage could be inmproved. I could see more power resulting from it since the engine is cooler with more airflow through the radiator. Cooler equals better timing curves for the pcm and maybe a denser intake charge.

I juse recently installed a new 160 T-Stat.
It works great cooling the water temps.

Please explain to us how a thermostat cools the water temperature... 
Unless the ambient outside temperature is moderate a lower temperature thermostat will make little difference in engine operating temperature.
The cooling is done by the antifreeze's transfer ability (60/40 water/OAT) and the cooling system's efficiency. (radiator core size and fan size & programmed fan kick on temperature which is 216 & 224  )

Your right. I actually was thinking more than the words I wrote down.  Yeah I understand the fans (Not the Thermostat) and radiator, etc. controls the coolant temp. I did however flush the radiator and refilled with new coolant + Redline Water Wetter and new 160 T-Stat. Sorry for the mixup.

Thermostat sets the lowest operating temperature. Fans set the highest operating temperature.
So, sitting in traffic or during stop-and-go, you are a slave to the fan settings. Cruising on the open road, you should be running at or near thermostat temp, assuming your radiator and coolant are efficient.

Interesting that my temps (according to Ford guage) were usually running half ways between R-M in the word NORMAL.
Now I can be driving freeways speeds and it's at N.
At stop and go traffic its at R.

I have a Autometer and it now reads about 215 in traffic and about 185-190 when hauling arse. I have the 160 T-Stat. I truly think that the SVT Radiator is not efficient enough for the 3L in 110 heat. PHX is hot as Hades right now. I am okay with the temps now, but 232 was a bit high for my taste.

There is no appreciable difference in heat generated between 2.5 and 3L engines under normal load and idle.
Only under full throttle where the increased intake charge causes some increased heat would I be concerned about it. I haven't heard of any other SVT 3L setups having difficulty with heat, starting with myself and I toured around phoenix visiting my friend all the time.
I'm beginning to think your radiator may have become less efficient due to sediment buildup or perhaps the cooling fins are full of dust.
Think about all the normal 2.5L that do fine in AZ temps with the smaller radiator and ATX. The SVT radiator only really comes into play under track/racing conditions of continuous full throttle. It should be more than sufficient for any 3L.

ok, this is one of the very rare exceptions that this information may be helpful. heres the lowdown, I was using these radiator motors for battlebots and you can really push alot more power out of them if you want. Basically they run flawlessly at 24V heres a little motor chart I made of the 2 http://www.mrgoodbytes.com/neco/ev/book1.htmland heres some tweaking you can do to the motor itself http://www.mrgoodbytes.com/neco/ev/I have alot more info I could drag up if any one wants. ~Terry
