Engine break-in. Should I be worried?

The car I bought was a "demo" car, with 540 miles. After I got home, I went through the manual and is says to keep the rpms below 4200 for 2,000 miles (if I remember the mileage right). I'm willing to bet the engine went above 4200rpm in those first 540 miles. Should I be worried? I do plan on selling it before the warranty is up. I've seen some websites that recommend pushing an engine hard from the beginning to seat the rings, etc.. I've been told these engines are "bullet proof." So why does Porsche tell you to take it easy for such a long time?

You'll get as many answers as there are members on this forum
Overall, it looks like the average 6speedonline member is more careful regarding break in... My personal take on it (as well as a number of Porsche mechanics -which I am not-), is that these engines are strong enough and have tight tolerances from the get go, so I would not worry too much. You can be sure that a bunch of people have beaten the crap out of the car when it was a demo (did the same with all demos I drove).
If your car is a manual, I would worry more about the clutch than the engine.

Anyway, you have a warranty and I would not worry. Enjoy the new ride!

If yours is a PDK with SC I think I'd postpone the thrill of using launch control until the brake-in period is over- as a warranty precaution. They will forgive you if someone tried it before you bought it.

You will be fine. My only suggestion is very the revs for the first 1500 mile or so. You don't need to be under any limit.

And I agree with chuck...hold off on the LC for the first 2K miles.

Now that's the type of question you should've asked before buying it.
I think most whom test drive a 911 want to see what it can do so they drive it like they stole it... I know I did.
That said, with only 540 km on it the amount of "abuse" it suffered is minimal I would think.
Also Porsche runs the engine to the red-line several times at the factory (a mechanic at Porsche told me one of those red-line tests/break-in runs last a whopping 5 minutes...).

I think you'll be fine, at this point no sense in thinking about... what's done is done.
If I was you I'd just go out and enjoy the hell out of that beauty!

Cheers!

Hopefully that means she is hot, AND knows what she is doing...!
Hearing that they redline at the factory for 5 minutes makes me feel much better. At the track, you could easily see sustained 5-7,000 rpms for long periods. On a test drive, it may go up there, but shift quickly after that. Hopefully all is well....

No issues
A hard break in is preferred
You probably have a better broken in motor than if you did it yourself...

I agree with Sid, what's done is done (and unknown) at this point, so don't worry about it.

If real damage was done (unlikely), hopefully it will show up within the warranty period. If not, you plan to sell it before then anyway.

But going forward, if it were me, I'd follow the official Porsche break-in rules. Opinions on that vary, but my default is to follow the rules unless there's strong evidence to the contrary (which I haven't seen).

Good luck and enjoy.

Yep, for warranty sake treat it like you were being recorded- because you are.

I will have to read the manual again. You are implying that the warranty is void if you don't follow the break in procedure precisely. Seems extreme....

They probably wouldn't push it (doesn't sound like Porsche), but why take the chance.

Short answer.. nope. I picked up my car with almost no miles on the ODO. Drove it 1200 miles- then took it to the track. I ran the car on the track for like 7 hours in Sport Plus mode. I needed a new set of tires after one day So, when I took it back to the dealer for tires... got an oil change. That's about it. Car seemed happy on the track and I gave a 3.8 GT3 RS a run for his money all day

That's awesome....I got a new engine in my 05 due to IMS and was on the track after 600 miles. that was 3 years ago and maybe 30 track days later.

And I don't even have the DFI engine.

For all the negative press these engines receive sometimes they can take allot of strong use.
