This is a very practical and clean mod man I might try it out. Whats your normal street temp vs track if you know? Also, I have to ask, any rattles?

On the street 180-200F depending on outside temp but even in the late fall/early spring it can make it above 180 without any issue. I only do autox (at this point atleast) but after a ~60 sec run it will go from 200 to 220F. By the time I'm up for my second run it's back down to 190-200F.

Block off plates are both on for street driving and both off for autox.

gomer nice setup with the plexi, i would have never thought of that, I used black sheet metal, 2 pieces with velcro.

That is true there is a trickle that comes out but I simplified it considering he prefaced it as noobie question.

Cut it in half with a block off plate? That's up to your cars temp gauge.

Anything over 260 is bad. At that temp oil will start to break down really fast and no longer protect. This is where picking the right oil matters. The better the oil stock the longer it will protect and not break down at high heat.

FYI redline and motul use the best stock called polyolester.

FWIW, some experts consider 210-215F to be the optimum oil temperature (best viscosity, shear strength, &c) for a DD. Just what I've read so YMMV.

It depends on the oil. Amsoil usually gets to that point faster when the oil is cooler. Just a thought. I use whatever oil works best for me. I am not an Amsoil bandwagoner.

Yeah. Probably varies a bit between types/brands and what engine they are used in.

My guess is that the boiling point of water has more to do with the experts' figures than shear strength or other parameter (most graphs aren't very steep once the oil gets over 180F or so). I've seen 212F/100C used more than once. BPoW may just be a convenient reference point. Maybe it's to make sure any water gets boiled off. All I know is what I read on the Intertubes. :)

How is this possible if your not moving the oil temp sensor? Also, UpRev Cipher reports the same oil temp as my gauge.

The only thing Japanese about Mishimoto is the name. CSF or go home

Is this because the sensor is in the return tube or something from the cooler?

After installing my stillen oil cooler it seems to fluctuate a lot more.. but I'm hovering around 180 degrees still during hot summer times rather than 210ish. If that's the case then my oil cooler doesn't really do anything other than when I'm on the hwy, which reads like 140 degrees lol

You need a thermostat plate. 140 deg oil temps are too low

Yeah, it gets really cold on cold nights on the highway lol. Should look into one..
