Anyone have a link where I can purchase a 180 degree thermostat?

Thanks

 

If it's all the same, I'd get a 200 degree or higher t-stat. Modern engines operate at higher temeratures for better efficiency and less emissions. If you're going to replace the stock, get a high temp one that uses a better wax compount. Cost you a couple of extra bucks ($100-$200), but will likely result in a better running engine.

 

From what Ive been reading on this forum, I should go with a 180 degree thermostat because Im getting ready to redo my whole exhaust - headers, Y-Pipe and new cats... along with the Superchips Flaspaq I just ordered, don't I wanna run cooler?

 

Historically, yes. In the past the t-stat controlled the amount vacuum in the engine as well as the temperature. This is not true of modern engines as the vacuum openings are regulated by the central computer. Nowdays, the only thing the t-stat controls is the flow of coolant around the cylinders in an effort to try and keep the operational temperature as constant as possible. Metalurgy is the main driving force behind this. The amount of shrinkage/expansion of metal in the engine can vary drastically with temperature. Physics has almost nothing to do with it.

Having said that, you don't want to go overboard and run the engine at 240 degrees or somethign equally crazy. The engine oil can only handle so much before it starts breaking down. But a few extra degrees (as long as lubrication is properly maintained) will help to get both an easier and a more complete burn, resulting in faster response from the engine.

 

Well you certainly seem to know what you're talking about. Although, Im concerned because it contradicts several other posts Ive read. Now I dont know what I should do. I do appreciate you sharing your knowledge with me...

 

No problem. Try asking a mechanic in person, see what they say. In fact, ask two different mechanics and see if you can get some sort of a consesus on the issue. Then post back here so we'll all know what the professional opinion is on the subject[8D]

For now, like the old saying: when in doubt, keep it stock

 

To answer the original question you can get a 180 degree thermostat at www.rpmoutlet.com They run $25.00 hope this helps.

First time I've heard to run a higher temp t-stat, anyway from what I've researched the way superchips increases the engines output is buy tricking your computer into thinking that the engine is cooler than what it actually is thus adding more air/fuel mixture and advancing the timing. Adding a lower temp t-stat can only improve your performance. Increasing your engine temp raises your likelyhood of spark knock/pre ignition and lost performance. Your EGR valve plays a big role in this as well, Cooler engine =less exhaust gas is recirculated into your intake air to prevent spark knock =more air fuel mixture . Cooler engine = more air fuel and advanced timing = more power.

 

Thanks Exchevy, that pretty much coincides with the other threads I've read on this subject. By the way canram, although I appreciate your knowledge, I did ask my brother in law who is a big rig deisel mechanic and he said the same thing Exchevy just stated. I think Im gonna go with the 180 degree thermo. You guys have been a great help.

 

do they make a 180% thermostat for the '05 dodge ram 4.7L and what kind of power gains are expected?
