1865 miles the magic number?

I’m curious about this too. So many different things you hear. My SA said you don’t need a break in period. A different SA said the ECU automatically limits the car appropriately so you don’t have to worry about it. When I went to a track day where they brought some new cars I asked and they said they just make sure they get a few hundred miles an the cars before track events. One interesting thing a dealer told me was that they have seen cars that had terminal engine damage due to the owners changing the oil too early and too frequently. I guess they need a little bit of grit in the oil to properly seat the piston rings. I’ll probably just stick to what the owners manual says.....

There are a more important variables that play to long engine life than a few revs when the thing is new. Oil should always be up to temp, and should be changed regularly. Over-revs are to be avoided, largely covered on an auto / PDK of course but relevant if you own or are buying a second hand manual. In a manual, how you shift and how you treat the clutch.
Last new 911 I had was on the track a few hundred km's old, the dealer knew and was fine with it. Their only request re. warranty was no sticky tires.
My comment "1 lap, then go for it" was a literal quote from our very experienced race engine builder in the 80's and 90's. We built and ran a number of engines using that ethos with no issues; his only requests were some load to bed the rings, oil temp., and any drive belts checked for tension after that first run.
But hey, if you feel better following a break-in process then by all means go for it. Your money, your choice.
