This was sitting in traffic after driving for about thirty minutes. Ignore my tire light, I still haven't coded out my air ride.Name:  20180605_173128_HDR.jpg

^I like that. Mine regularly hits over 210 on that gauge here in South Texas. Starting to get brutal. Need to put this on my more immediate list of things to do.

I'm consistently at 210+ here in Georgia until now.

Question for the guys running the thermostat; are you running the lower pressure radiator cap like logic7 suggests on their site?

I'm not using it, all good on my e53 and e39

I'm honestly unsure what the benefits would be to doing this.

Engine coolant, oil and trans fluid are part of the overall design/engineering. The criteria being to optimize performance, efficiency and emissions. There are some exceptions, usually due to mods but even then it is to reduce the temps to original specs. The downside potential of lower engine temp is much greater than the upside. If the transmission is "happier" it is because the lower temp happens to be a bandaid for another problem.

Most likely the solenoids. As is the case in mine...

You can not optimize (to the highest achievable numbers) all three of those things. As is the case with most things in life... there are trade-offs. Lowering the operating temperature may hurt efficiency... but at the same time increase performance. We will probably never know as I doubt any owner will do a before and after dyno after installing one of these thermostats.

As with your suspension mods, there is a cost benefit each owner will weigh when making these choices. I would most likely think your truck rides too rough... you'd think mine doesn't handle well. I could use your BMW designed it as part of the suspension geometry and handling of the truck position as well. But I understand that your goals and desires for your vehicle are different than mine might be.

Didn't mean by optimize that all goals would be at max potential. Certainly there are tradeoffs. Problem is that what direction a temperature change impacts the variables is not predictable. Force a greater amount of cooler air into the engine. That's a measurable ROI.

Upgrading the suspension is entirely different than replacing worn out parts or rebuilding a stock suspension. The difference is that the upgrading is making changes that universally and predictably improve handling. Since there was no suspension upgrade package I went through several iterations of shock and strut combinations to get what I wanted. I did all the upgrades at somewhere around 25,000 miles and did it all again just over 100,000 miles. I don't remember how much ride changed but it can't be much different since my wife has never complained.

Now there's an empirical measurement!
