First off, it doesn't sound like we really know the source... it sounds like "someone might have heard from an engineer.....", but I'll believe it when I see the words from the engineer, and it was a mechanical engineer working on the engine/drivetrain, not a audio engineer working on the speaker system who heard from his brother that works in the drivetrain dept. that 260 is the maximum safe temp.

Personally, I don't buy it. 260*f sounds extremely low to be a maximum safe temp, maybe they meant under 260 is "ideal".

Second off, from your screenname, I take it you go to/went to NC State. I graduated from there in 2008.

This. You can mix oils but the pressure you get (well that I got) with 0w20 makes it pointless IMO. The very little MPG increase isn't worth the effort of changing it just for track days, and then swapping back.

I change my fluid on cars I track and lower OCIs so the oil in the cooler doesn't concern me much.

Based on information I've seen over at Bobistheoilguy.com there are quite a few high performance cars (Vipers,Mustangs,Vettes) running their oil temps up in the 300s without issue. Now that doesn't mean we won't have an issue at the same temp, but it does make me wonder what about our engines could be so different as to make you not want to run the oil temp that high.

We know the car cuts power, so thats a sign that the engineers are a little concerned about oil temp (unless that is common with other cars, I don't know).

Do higher oil temps have an effect on direct injection? Is it something more boxster specific?

I'm still going to run a cooler under the better safe than sorry mantra, but I am curious what else we are missing.

so is the Oil Galley a good place to add a oil temp sender? I want to keep an eye on the oil temp before I get oil cooler.
thanks

car has a oil temp gauge stock. Buy yourself a Scangauge or other OBDII reader to read oil temp.

Next time we are both at Sebring we should use your scangauge in my car to compare the OEM reading vs the one from the Defi. I placed the sensor right after the cooler so it will be reading lower, just curious how much lower...

I am currently using a Scangauge, but I will be replacing it this weekend with a Defi DIN-Gauge that will be reading off of a sandwich plate. I'll post up what I find.

Quick question: did you install the sandwich plate for your gauges above or below the oil cooler sandwich plate?

Above so I would know immediately if a cooler line failed.

Where are you mounting your Defi gauages?

You are correct sir! Go Wolfpack!

Ya know, I only run 1-2 track events a year. I don't think its worth it to install an oil cooler (in my case). I'll just make sure the oil is freshly changed a week or so before hitting the track.

It will be sitting right above a new single-din headunit. Credit where credit's due: I'm simply copying what I've seen two other members do:

That looks very clean.

Where do you buy that Defi 3 gauge DIN?

The ecu pulls timing and the car loses power when the oil temps get to 230F. I think that is solid evidence that 260F is too high.
