The only thing they need to focus is on making the whole platform lighter, the cars are getting heavier each gen.

Many hurdles to pass and a bit pointless. Car already makes truck loads of torque that is putting a strain on pdk, 4.0 would just make more torque and heavier internals with less space for cooling the chambers that run usually hotter than NA cars.

Is the 3.8 that much smaller and lighter to make a difference when the 992 is already bigger in every dimension? Seems the 4.0 is perfect to TT for that chassis.
My guess is they are working on something like this right now.

No, the displacement change has nothing to do with external dimension changes (in last generation the 2.9L Cayman motor and 3.8L Carrera S shared the same case. I think the 4.0 is likely a bit lighter than 3.8 with hollow crankshaft and Titanium conrods.

There is one caveat though, and that's if you're lucky enough to get a new limited edition model like a P1, a 675 LT, or a Senna.

I see Porsche left no stone unturned on the design of the motor in 2RS and I hear the word "Motorsport" mentioned at least a couple dozen times in the video, but why? Is it worth it for Porsche to pour so much R&D and "Motorsport" DNA into such a limited edition car??? Not if they aren't planning on homologating that engine setup for future Cup/RSR cars IMO.

It is obviously totally track and slicks capable to be used in the new 935 and GT2 CS - maybe this is the new normal?

I think Porsche has no choice but to go with a turbo for the upcoming RSR. The competition has gone or is going that way already. 935 and GT2CS are the first steps along the way. And also why the latest GT2RS was designed the way it was.

Even if turbo is the future, there is no mandate to use wet sump. As a buyer, I’d much rather have turbocharged version of dry sump, hollow crankshaft, solid lifter, high revving motor in GT3 and RS...

Golden Boy: No its not. 2RS is faster. The 3RS provides more performance per $$$$ comparatively.
Grant: The 2RS 3.8 is not a Motorsport engine to my understanding while many of the fixtures pertaining to the turbo charging are.
The fact the 935 and 2RS CS use the same engine doesn't make it Motorsport in that the motor was not developed for racing as with the 991.2 4.0L nor was it used in the factory programs.
Its the same TT 3.8 used in the Turbo S with some strengthing bits internally.
Am I wrong?????

This article makes me even more anxious to run my .2 3RS against the Cup Car. Road Atlanta is better suited for this test because of the higher speed corners and limited long straights. I'll keep you posted when we get this scheduled. I will see if I can find someone locally (Atlanta) that would allow Bryan to drive their 2RS so we can compare the three cars. Too much time, money and effort to send my car down for 5 laps. Both cars would run same Trofeo R tires to make it equal. Anyone interested in having their car participate can PM me.
