Thermostat

I think most people run the 180 in conjunction with a tune or if they go with the air gap intake...

I never heard of a cool engine having a short life span...

Get a programmer bro... Have some fun setting your fuel maps and spark and fuel curves. Plus you'll pick up some hp and possible mpg/ Whatever you do, DO NOT REMOVE THE THERMOSTAT. You have a 5050 chance of it running super super cool, or totally overloading your engine with coolant and overheating it.

If you do anything use a 180 I have been for a long time and you can't go wrong with it

The lowest most people go is with the 180 t-stat. Stay with that or stock. Don't go causing yourself trouble.

This is an arguement I have with my friends in the Philippines (hot conditions) all the time. Their thought being is the engines don't need thermostats and should be removed at the earlist opportunity. My position is engines need to stablize their operating temperature as quickly as possible to reduce condensation and bring the oil up to temperature to remove any condensation that has been previously trapped. This ideally is for the oil to be at 160-180 degree for 20 minutes. A stable temperature helps an engine maintain engine tolerances that reduce wear and allows the electronics to operate within it's designed parameters. The modern electronic's of today's vehicles are efficient at adjusting A/F and timing which is the basis of what makes a engine run. The various sensors provide the needed inputs to the PCM to achieve this optinum condition. If the sensor(s) are operating outside the designed range (temperature) the PCM then cannot operate as originally designed and will throw a code indicating it's inputs are not valid. These codes are often emission driven, to alert the operator that his vehicle is not within it's factory settings. Performance tunes in many cases raise emission outputs and IMO if they don't then they are not doing anything as HP requires energy. Heat is a byproduct to making power, more power you have the more heat you need to disapiate. heat is the destroyer of engines. Having an engine running cooler at a stable temperature is better than one running at a higher temperature. Cooler fuel/air allows for denser mixture and more ignition timing. Manipulating the sensors to indicate cooler temperatures then what actually exist allows the PCM to adjust to richer fuel/air mixture and increased timing but doesn't provide the benefit of actually having a cooler condition. Anyway, my two cents. I hope this has made some sense.

Thanks guys, think I'll just go with a 180 so I don't have any trouble

hemi stock was like 203* i put a 180 in a no codes...

[ramthis9501]

I think it's stupid that they make these engines run so hot, according to Chrysler, 212 degrees is optimum for these engines... yeah optimum to make them explode lol

Dude... 160* is gonna do nothing but help your engine... Not give you problem's. Some people are just scared to change thing's out to help their engine's because other people get it in their head's that an engine running cooler than normal is "NOT GOOOOD".

Will it drop my mpgs or raise them?
