It makes reaching decisions about all sorts of things difficult. It'll really screw you up...especially when it comes to dealing with women
Just "visualise" boobs
Works for me.
Say- here's another way to look at the 180* Tstat idea:
If your cooling system has little to no margin to keep down temps in anything other than low-stress driving conditions, you get a temp rise when you boost, right?
OK, and let's say that's with the 192* Tstat. What does that mean is happening inside? The Tstat(as I think you already mentioned) is probably wide open most of the time, letting the rad do it's thing as best it can. So what happens if you put in a 180* Tstat? It opens even sooner, and stays open even more constantly, because it's supposed to flow at 180*.
SO! - If your cooling system isn't ALREADY up to the task- AKA- a good radiator, water pump and clean coolant(also very important), putting in a lower temp Tstat will give you about the same temp on your gauge. Heck- now that I think about it, If you could easily swap lower and lower Tstats in and out, you could find out what the lowest maintainable temp would be of your cooling system. If your system could maintain 140*if called upon, for example, that would demonstrate your system's "safety margin".
:wiggle:
PS- I think that the 192 Tstat was originally chosen for the engine based on expansion of various parts, existing tolerances and the designed operating envelope, but I dunno for sure.

^i know where you're coming from but no
my radiator can handle plenty of heat and there are some pics of just how cool it can run with NO T-stat cruisng on page 3. Given it was a cooler day i think in the 40's? but either way, its ability to rid the system of heat is quite good.

Well, heat transfer on a 40 degree day is juuuuust a bit easier than on a 90 degree day. But hey- as long as your happy with your system's performance.
Again- my oem-type rad was only a year old and it would overheat in the summer with a fan shround and no undercover. Switched to a larger radiator and never had a problem again.:icon_bigg

The reason i asked is because i used to race bmx and there was a huge race in Kansas, both KS and MO were fucking MUGGY as hell!!! Its kind of funny how we are just listening in on all of this temperature bickering and having a low blood pressure conversation at the same time lol!!!I apologize for the following OT post, but as a semi-lurker who happens to be a Mechanical (BS)/Nuclear (MS) engineer I have to stick up for the "indepth analysis" that people are knocking. If you do a proper engineering analysis using say the Log Mean Temperature Difference technique you will demonstrate what most of the posters in this thread are saying.
To "IwantMKIII", I would highly recommend modeling the radiator as I believe it would significantly advance your understanding of the basic engineering principles around the system. Real world application of engineering fundamentals is very benificial because you can easily get lost in academia formulas.
