if only I could figure out how to change the oil without a catastrophe occurring...

FWIW - I've had a catastrophe changing my oil haha ! It was like the Exxon Valdeez - just replace the once pristine water off the Alaskan coast with my garage floor and the crude with sweet, sweet XP9... what a cluster !

I'm sorry I'm not in Mass, because I'd be ALL IN!!
After I'd found a roller and built it up... Nice work gang! I love this thread!

It can't hurt - the oil temps could certainly stand to come down. The data shows there is instability in pressure when the oil is hot, and that where pressure was dropping, the hotter oil caused it to drop further.
Ideally, I'd like to get rid of the dip there... the hotter oil is exacerbating the issue.
Water temp although not shown in the data above at the points being referenced was 210 F and 194 F.
So, a 3rd RAD with the bigger 997 cooler coupled with an oil feed solution to get rid of the dip to begin would be the solution I would like to implement. I may get the 3rd RAD and plan to install before the JUN track days, we'll see... because the water temps have always seemed to be manageable, I did not want to spend the money if it wasn't needed, kind of sucks that it may end up being the case as a way to address the oil temp issue.

Nice lines out there today. The former (bike) racer in me kept wanting to dive the corners to overtake that traffic...ESPECIALLY that Acura (?) sedan. I was yelling "DUDE - YEILD TO FASTER TRAFFIC instead of clogging the line...."
But that would have been a dick move on my part...

Jason, our conversation yesterday coupled with the direction of this thread on water and oil cooling got me checking what Charles at LN engineering has for oil cooling. He does have Bilt oil to water heat exchanger.
Charles, if you see this, can you comment of how this works, additional parts needed, configurations with additional water cooling, bottom line: your thoughts, options and recommendations, etc? Appreciate any insight.
Since we have a lot of seasoned folks within RL, maybe a few can share what they have done regarding water and oil cooling. What parts are you using, how did you address it, and has it worked?
At the end of the day for all of us, its about prolonging the life of our engines. Jason has the analytics to measure water and oil temps, plus oil pressure thru a complete lap on track, which will help to quantify the issues or potential issues.
He and many of us have the 2 quart deep sump w/ baffle, and either a motorsport AOS or UAOS. The next question is what else is needed? Maybe nothing, maybe more cooling.
For those that don't drive their cars on the track, you can also potentially benefit from these specific mods which may result in engine longevity. Too many garage queens have problems thru lack of exercising your car, inadequate service and preventative parts and care. But that's a whole other topic.

Glenn - Check out THIS THREAD ON OIL COOLERS I started a bit ago.
To sum it up - a setup using LN's Cayenne spec cooler and a 3rd rad has reportedly been done successfully. I would love to see data showing the affects - especially because accomplishing that setup is 1. A lot of work the oil cooler is not the most accessible part bolted to the motor) and 2. it's a lot of money... So - it would certainly be preferable to know what you're getting.
Which is why I put the data system on the car, where that stuff doesn't exist or isn't made available - I'll publish whatever I get. So, if I do go that route, I'll share all the data.

Would it be possible to mill an aluminum plate with nipples so as to relocate the cooler to a more easy location to work with and or physically alter its shape and size to your benefit?

Thanks Jason. Somehow I completely missed the thread. Good info. The problem with having a great car like the 996 is you spend too much time thinking about how to make it better, faster and stronger. But...we all need a vice don't we.

I'm running the 2L deep sump and 3rd radiator in addition to CSF side radiators. I want to increase the airflow and have been contemplating deleting the AC as I hardly ever use it, though I may be able to clean up the air vectors with GT3 wheel arch liners.
Nice lines out there today. The former (bike) racer in me kept wanting to dive the corners to overtake that traffic...ESPECIALLY that Acura (?) sedan. I was yelling "DUDE - YEILD TO FASTER TRAFFIC instead of clogging the line...."

When I was tracking both my Boxster and Cayman, I eliminated one of the two a/c condensers on both cars like how Porsche did it on the GT3. Didn't hurt the function of the a/c at all except if the car was baking in the sun and it was ridiculously hot and humid outside. It just takes a little longer to catch up in those instances. We ended up making kits for these, but I only have them for 987/997 and later models currently :-(
