For Break in Period - read this: https://rennlist.com/forums/991/9214...r-991-a-3.html
There are 100's of threads, and no real answer. My suggestion: for the first 500 miles or so, keep it under 4500 RPM, and then have at it. Some say 2000miles, some say doesn't need any.
I do the first 500 miles under 4000 RPM - more to get to know the car, understand the dynamics and feel, etc. The break in is more for me than the car, and figure doesn't hurt to let everything "break in" for 500 miles.
On launch control: Also there are dozens of threads on this. Also tons of videos. In one particular video they launch the 991.2 Turbo S like 100 times in a row, back to back, with no apparent problems.
Do as much as you would like, be safe about it and aware of your surroundings.

But.... there are a few pieces of possible misinformation that seem to float around about Porsche's and the break-in procedure. One is that in Germany, Porsche doesn't specify any type of break-in procedure. I've heard they only do this in America. Another is that that the engines are "broken in at the factory" and are good to go from day 1.

My experience with race engines is you build them and put them on the dyno. They are "broken in" on the dyno. Of course, the engine tolerances are looser than stock. Power goes up as the motor gets more miles and the rings seat better. There are millions of ideas about break in, but the science is on race motors. Do whatever you need to do to keep the warranty and then drive it like you stole it.

Anybody 0-60 a 7mt yet?
Im curious if you actually really lose almost a second doing a manual shift, in a lighter car that only needs one shift to 60...
...or if they just put a really conservative figure out there as part of there scheme to stomp out what’s left of MT demand.

I was using a iPhone based app called Race Timer, which sucks and probably not accurate. I first did a couple of normal driving to see how my speedo calibrated according to this app and a standard speed GPS app (I use the 2nd one on my jeep to see how much the larger tires changed the speed, and what I needed to tweak the settings to adjust properly) Firstly, both apps showed my speedo on my porsche was about 2mph quicker than what the apps said - ok somewhat interesting. Again most of this phone based apps suck, but looks like the speedo may read a tad quicker than in actuality.
I have my Vbox in my maclaren 720, but didn't move it to the 992 for this test. May do it later to get more accurate reading.
All runs on a relatively flat stretch and decent road. All runs was from complete stop, without slipping the clutch for added RPM gain that you can get. Since I am at 1K miles, I did not try and kill the start or drop the clutch for best start.
All test were in sport mode:
First run - 4.2 second (decent start, my shift to second was a bit slower than run 3)
Second run - 4.5 seconds (Bad start, and horrible shift to 2nd) - you would think I never drove a stick shift..)
Third run 4.0 seconds (This was a good run, smooth start and shift to second was quick).
You could definitely get to a 3.8 seconds with the manual C4S or S if pushing it. Which would put it about the Base Carrera with PDK and Sports Chrono time.

Using a Draggy, on a 2.3% slope, with a full tank of gas, overfilled tires, 84 degrees F and a DA of 2084 ft, got a 3.51s 0-60mph with 1 ft rollout. Car is a 17 C4S with 67,000 miles, stock. Will be getting an APR stage 1 tune in July, so I’ll post comparison numbers afterwards.

What chip tuning did you use on your base goDragy?

I will hook up the vbox, or buy and extra dragy for this car and do a few runs.
With a 1 foot roll out that would improve my times I posted above, the cheap app that I used did not allow for it. That would be a few 10ths better than what I recorded from dead stop. I will do a few runs this coming weekend with a real app to see what the real story is on the 992 manual.

You can draw your own conclusions there, but to me it sounds like the special advice given to US customers is less about mechanical issues than legal ones.

Porsche is also on record as stating that they recommend this to their US customers, while simultaneously recommending that their European customers drive their cars flat out from day one, if they wish.
You can draw your own conclusions there, but to me it sounds like nothing more than a legal thing.

And if Porsche also printed in the owners manual of US-market 992s that the car could drive underwater? Or fly?

Then there is the engineer / pilot mind that I have that tells me that the laws of physics (friction being among them) makes it such that a brand new engine running at max power is guaranteed to wear a lot faster than one that's had time to seat bearings and rings .. 😂👍

Those are strong numbers (is that is a manual trans or pdk).

Unless, according to Porsche, that engine is being run in Europe?

To be clear again, Porsche has stated that they tell their European customers that running their cars flat out when new is fine... So you wouldn’t buy any used Euro-spec 911?
