Default 180 degree thermostat?

I see several of the members talking about running a 180 degree thermostat during the summer so I would like to know how or if this adds anything to the performance of a Hemi?
Also, is this allowed under the factory warranty?

Well, I don't have a HEMI myself, so I can't presume to answer to how it affects performance per se, but the premise is a cooler running engine is a more efficient engine. A 180 t-stat opens at 180 degrees, which allows coolant to flow through the engine at 180 rather than the 195? stock thermostat. I don't see where it would affect the warranty, either, but, there again, I'd rather let someone who has a more definitive answer help tackle that question. Hope this helps and perhaps anyone with more expertise than myself can chime in and add to this for ya'!

The lower value tstat allows the engine to run cooler, thereby improving engine efficiency and power.

Anything is allowed under the warranty as long as the modification doesn't cause any damage.

I've been running a 180 degree tstat since May of 2007 in my 6.1L HEMI powered Chrysler with no ill effects. I've noticed my car runs cooler on the highway and in city driving as the engine coolant begins to circulate sooner.
