This dilemma is as old as motorsports. I used to race several sleds and motocross machines. All two strokes and I can't tell you how many times they were assembled and run in for 3 minutes and then held wide open for three hours! And that was 30 years ago. Porsche has short break ins covered in their engineering. Rip it!
Just need to seat the rings to improve sealing. Should be done in less than 200 miles with the right type of procedure. Helps in long term oil consumption and reduced blow by. If you are gonna race right away and rebuild often, you don’t need to do it.
I guess some people on past engines didn’t seat the rings well and were needing to add a bunch of oil or something so they have this “warning.”
With modern manufacturing, you aren’t gonna “hurt” the engine by running it. Guarantee you that running it WOT on track all the time is way harder on the engine that 7500 rpms a few times in the first few hundred miles.
These cars are incredibly well built. Unless you are concerned with power and oil consumption at 150k miles, enjoy it.

This is what mu Upstate dealer said:Regarding the break in requirement, I did reach out to Porsche when xxxx asked me to. I did have to follow up on the answer, but I heard back that every vehicle stands alone with break-in requirements as specified by the production team and that RS models are more specifically designed for track use, and because of this see a stringent factory Pre-test that is longer than most, and reduces the customer break-in period. The comparison that was used in answering us is that the GT4RS has an 1,875 Run In (Break In) period and the other 718 GT Series models that carry a 4.0 liter engine (GT4 and Spyder) have a 2,000 mile break in period (No track use, take longer trips instead of short trips, and avoid engine speeds of 4,000 RPM or higher). They really do not compare the mid-engine vehicles (718) to the rear engine vehicles (911), they are completely different vehicles even though they mare share certain components. There is no technical answer beyond that, but the recommendation is to follow the vehicle specific owner’s manual and the vehicle multi-function display which it sounds like you are doing.
Take it for what it is worth but Porsche a has always been very specific on break-in requirements. It is just very strange the the ROW 4RS's are completely different than the US cars.
I think there is some confusion on the North American run-in on the non RS cars going on here.
The OM says something like this: The moving parts of a new vehicle must be run in. The parts require the first 2,000 miles (3,000 km) for this purpose. The oil and fuel consumption may be somewhat higher than normal during this period.
And about the 1875 for the RS and 2000 for the non .... I call BS
You have said the before and I respectfully disagree. It is such a blatant difference that it is beyond lawyers and on the verge of being comical. Do they (the factory) really think that no one will notice the difference or that a ROW owners would not have a legal position if their engine gave out prematurely?

Please explain how these cars differ mechanically from the ROW cars to warrant such a difference. The US is litigious compared to ROW. Just look at all the BS on buy backs.
Just the simple statement from your SA about 1875 and 2000 with totally different engines is BS. Its not even covered in the manual (manual has error as @TXshaggy identified. The same engine in the GT3 over here is 932 and 7k rpm. Tell me how they differ between cars.
BTW, RL has exposed numerous SAs for being less knowledgeable than the membership.
Meanwhile I drove a 50 mile GT4 at PEC Atlanta who's only "break in" was 10 laps ahead of me by the instructor to make sure things were sorted. That car will eventually get sold.

Wow, @exMB you sound angry. I am not disagreeing with you at all. I am merely trying to get to an explanation from PAG or PCNA directly why the same engine in the same car can have two different break-in periods. It has been pointed out by others on RL that local dealers and PCNA themselves have said that an above requested rev situation during break-in is not a warranty spoiler. Besides, were it to be the case, all a lawyers would need to do is present the two different OM's and the case is won. PAG and PCNA are not that stupid. The one thing that I will give you is that the US OM may not have totally come from PAG. Inside the cover of the front cover of the US OM it states: US GT4 RS Owner's Manual
