I don't know if this is the same for the "rest of the world", but here's an excerpt from the UK GT3 owners manual.

It's your car, break it in however you want, but no, they haven't......

A few percent (single digits) of motors are pulled off the line and briefly run in hot for quality control purposes. The vast majority are not.

At the end of the production line, each car is run on a rolling test bed for a couple of minutes at speeds up to 70-80 mph. That's it.

Where exactly in the production process do you think that the motors are "run out"?

Exactly. "Running- in cannot be completely avoided" means that Porsche assembles and heat cycles the rotating assembly but they can't completely break the motor in for the consumer. There's a lot of initial wear that will happen and that's why they recommend "long trips" so that you get some nice long heat cycles into your motor which make the Porsche gods (peace be upon them) smile and bless thine engine.

Agree. Just to be clear, except for the very few engines that are run in hot for quality control purposes, most engines are not even heat cycled. The new engine production line has a station where every engine is spun cold on a computer monitored rig before the intake and exhaust assemblies are installed to make sure that all rotating clearances are correct. But the days when every engine was dyno tested and heat cycled are long past.

You are 1000% right and understand the facts ...I am a firm believer in drive it like you will drive it... Never had a main seal leak or any other issue in the past .. It's the same ole stuff we have heard since the inception of rennlist!! Lol do what seams best to you read the book ... I still think like many years ago the attorneys of Porsche want you to learn the car before you kill yourself or someone else lol

I wonder did this conversation exist on the 964, 993?

But this is only my opinion.. Based on past exp.. I wonder how many 997 failures are due to" improper break in" just curious I haven't been following this.. How many 991 failures are out there ?

Fair enough. I wasn't saying I disagreed with your break-in approach, only that Porsche doesn't run out the engines. Everyone needs to approach this with their own level of comfort.

I think the reason this subject is so open to argument is that there is no definitive study I'm aware of that proves what the best way to break-in is or hard numbers about failures. Porsche isn't going to hand out that kind of info. So we all get to argue our own opinions on the subject!

I might be concerned that if the recommended break-in wasn't followed, the warranty may be void. Obviously they would have access to all that info if they needed it.

I've broken in a good six 911 race engines that we rebuilt. Never had a failure due to how it was broke in. Are you going to drive the the car past 100k? Honestly. I don't think it makes any longterm difference how the early miles are driven. I could be wrong, anyone know any different?
