In order to understand how a computer electro-mechanical thermostat works,one would have to do some research if one finds that interesting.
In summary,the DME is capable of controlling coolant flow through the 3rd radiator regardless whether the Sport button is activated or not. In other words,start driving the car aggressively for an extended period of time,without depressing the Sport button and you will see the same results.

My car dedicated to track duty is my GTB1 Cayman. I'll take this car on the track maybe a few times a year. And in a few years when I retire the car from track duty, Ill put the PCCBs back on. Wish I did the swap to steel earlier with my 997 RS. Besides, I am the limiting factor of capturing the DE Cup, more than this cars performance.

Here's a view of the thermostat housing and its components. You can clearly see the electrical side to the otherwise good 'ole mechanical device. The DME is using a pulse width modulated signal to heat up the thermostat's element. The thermostat is part of a bypass housing that is used for quick heating on startup(emissions) and it's capable of directing the coolant flow through the 3rd radiator for additional cooling.

AP will only say what is needed to say. This does help with sales though.

I thought sport mode changed throttle mapping. Sure feels like it does on my Carrera S.

This. Driver variation is >>>>> than pdk vs manual variation. Unless you at F1 levels of racing where you can put it within 1/10th of a second of each other.

I recall that on the GT4, sport enables rev matching and decreases engine temps... it seemed to work that way on my GT4 when I took it out to Sonoma. I tried sport off and sport on.. and the engine ran cooler.

I think at this point it's probably better to just watch a Porsche commercial.

At least it'll be more factually accurate.

That you are a faster guy than other drivers. Absolutely normal, noting to prove.
What would be interesting to see is your lap times mt vs pdk :-)

My POS Apple Watch is on my wrist every day while my Rolex lays on a table, but carry on...

Agree with you on MT. Watches, not so much.

Boy....a lot of negative comments on AP as just a shill for the Porsche sales office. He is the unquestioned head of the GT program, whose cars you are all paying big bucks for.

Yep, it's an awesome option to have!!!

And I think we should go easy on the "ap is a salesman/politician " thing... he's a gearhead enthusiast who changes his mind daily bc he has gearhead A.d.d. like the rest of us:

-AP: "That is a very good question. My attitude changes almost daily. I’m driving a dark gray PDK GT3 second-gen at the moment, and I have a Guards Red with manual as well. I’m really happy I don’t have to make this decision. I think track-oriented people should go PDK, but for the driver who really likes to think, be challenged, and wants to be an integral part of the drivetrain, the manual provides a very satisfying experience."-

I think if he could, AP would be here talking smack on the forum with the rest of us.

Sorry,it was tongue in cheek really...not meant to be taken too seriously...

Regarding AP : he's part of the development team that produces pretty cool cars that we all enjoy. I've always regarded him as an enthusiast no matter what he publicly said. He has bosses,you know...
If you can read between the lines,you'd realize he always wanted a gearbox choice...going back to 2013 when the 991.1 GT3 came out. The Board gets convinced by numbers only,not enthusiasm. This time around the numbers came from the GT4 and the lack of development money the Board had to spend on a 6 speed. Bear in mind that the 6 speed you see today in the 991 R and 991.2 GT3 has been developed back in 2012 for the upcoming 991.1 GT3,but that project was dropped in favor of the pdk.

Walter Rohrl is in the same situation : he's going to say a lot of contradicting statements. You just have to understand yourself where his heart lies.
