Swap in the larger GT3 engine oil cooler.

DME coolant temps peak at 220 on the very hottest days but are typically in the 210-215 range. If the gauge value of either of them ever rises into the red area I would take immediate action (get off track and cool down) but I pretty much ignore them otherwise and make decisions based on info from the Solo.
Cool, that is definitely something I will do. I currently get my data on the SoloDL via OBDII so switching to CAN is the way to go to get more accurate readings.

Question: I looked and what i could find is that the CAN connector is in the back under the rear speaker. Any idea how much of a pain in the butt it is to tap into it? Additional challenge is that I have a roll cage installed and I wish that I was much younger and my back would be more flexible...

That's definitely on my list
Is that a DIY that you do during an oil change or is it more involved?

Default GT3 oil cooler

I did a bit of research and that doesn't look like a straight swap.

The 997.2 GT3 oil cooler (997.107.025.90) looks like a Boxster oil cooler

While the 997.2 oil (9A1.107.040.00) cooler looks very different

I think there is a company that makes adapters or something but not sure if it applies to the 997.2

As a non- racer, I would check the following:

1. Are radiators clean? The location makes them vulnerable for garbage collection.
2. Are three fans operative?
3. Is thermostat opening properly?
4. Have radiators been flushed or replaced?
5. Can oil cooler be cleaned?
6. I would be concerned with your oil temps.

Best of Luck!

Roger that on the age and back issues comment! A local Indy wired mine so I can't be sure but I thought the CAN could also be done near the fuse box. I'd post on the Data Aquisition sub forum of Racing & DE forum and Matt, Peter or Jerry will be able to guide you. The link below is for a GT4 but those connectors should eliminate soldering and heat shrinking. Hope it goes smoothly!

Maybe a 160C thermostat will help? Get the water circulating more frequently to prevent the oil from getting too hot in the first place.

Good article on low temperature thermostats:

http://www.tuneruniversity.com/blog/...the-advantage/

They seem to be useless at best and unsafe for the engine at worst (opening while engine is trying to heat up).

Sure, the explanations given on that site would make it seem that way, but Porsche specialists (Hartech, LNE and FSI) have weighed in on the topic and seem to be in agreement that the LTT is beneficial based specifically on their knowledge of the M96/97 design.

Like all other mods and aftermarket discussions, people will have their differences in opinion. And I don't know what Tuner University's credentials are other than being a blog site, but I'd definitely trust that of Porsche specialists that have years of direct hands-on experience on these engines.
