A 3,000km sounds like utter torture. May I ask a few questions:
1) Are the engines run in at all before being in the vehicle?
2) Is there a “bare minimum” break in period anyone can suggest that alllows the majority of run in to happen?
3) when is the first service/oil change needed?
Any other advice is much appreciated, but 3,000km is not possible for some us that are a bit heavy footed.
There are more opinions on this than you can shake a stick at. Some feel it's fine to run it hard on the first drive, some feel it needs to be done per Porsche's proceedure and everything in between. It's a decision you'll have to make as there are compelling arguments on both sides. Keep in mind you're breaking in the clutch (manual), transmission and CVs as well.
Personally I'd wager almost none of these cars see break in with Porsche's proceedure especially considering how often they change hands. And they're all mostly fine their entire lives.
On my own car I'd give it some running in but not the full 3000 km.
It's too bad Porsche doesn't run in the drivetrain on low volume cars. Break in mileage per the book is a significant chunk of the mileage this type of car will cover. I'm sure everyone would love to be able to cain it from mile 000002 without a worry
As stated above, there are opinions all over the board. Do a search. You can justify or rationalize whatever you want to do and however you want to do it. I do the break in for several reasons.
1. It’s printed in the manual as a way to break in the whole car. You don’t follow it, you take your chances on several fronts.
2. The 0.2 GT3 is much improved from prior versions, to include a much more pleasant street drive car, those kilometers will fly by. I did 2000 Miles in 5 weeks. Take it to work, to lunch, to dinner.
3. I would rather buy a used car with 3,000 Miles properly broken in, than a used car with 200 Miles that probably got driven like it was stolen.
I’ll let you guess which camp I’m in .
BTW, first oil change is at 10,000 Miles, sooner if you frequently track. I’m sitting in the dealer lounge right now, car just had 6 days on track plus the 2000 street mile break in, at 3,500 Miles for its first oil change and professional check up.
I read somewhere that at the Porsche experience center they do a 500 km (300 mi) break in, before taking them to the track. I would think that would be the bare minimum.
I have also read a while back the break in procedure recommended by a Porsche mechanic at the factory. Keep it under 4.2k rpm for first 400 mi, then 5k at 500 mi, 6k at 600mi,7k at 700, 8k at 800, then 9k at 1k. Also important to follow the other instructions in the manual such as varying your speed during break in.

This is basically the procedure I'm going to follow. I don't have the patience to keep it under 4K for 2,000 RPM. First 400 miles = 4K. Then increase 1,000 RPM per 100 miles.
Yea we've all talked about this, but with the new engine I am less worried about proper break in. I think the minimum break in with this new engine should be really good. On the .1 I think it was mandatory and needed esp the RS but I am less worried about it now. That being said I will be following what I was told at the Factory with first 500km below 5-6000, add 1000rpms per 100kms
There is no break-in requirement for your warranty. The break-in instructions in the manual come under the heading "Hints for best performance" or something like that (I remember the word Hints from my GT4 manual).
I have read several times on Rennlist (don't remember the thread(s)) that every one of the 991.2 GT3 motors is test run on a dyno to redline before delivery now.
All that being true, I still think it is advisable to observe AP's recommended procedure (or something slightly accelerated, ending around 1,300km as he says below):
"I videoed AP's presentation, and here is what he said:
“I can only tell you how I personally do it, or how we do it at Weissach – for the first 500 kilometres or 300 miles, we don’t drive that car car ever over 5000 rpm, never. From then on, every 200 kilometres, we up the rpms by 500, so we end up at 1300, 1400 kilometres at the threshold before we can really go full throttle, at 800 or 900 miles”
He then went on that this procedure was really important for the GT3 RS engines given their more "delicate" rings - and how important this break in really is for any of their engines.
Another point - he recommended to realign the car after 1000-1500 miles due to settling - especially since the tires are getting bigger and bigger, and more sensitive to changes. The RS apparently is really sensitive around this.
You figure the head of the GT program would give you the straight goods.

I did mine by the book. It hit the race track with 3018 km on it.
I'll try to come back with updates after a few track weekends but after the first one, it didn't use up any oil, which seems to me to be a good sign. A friend with a GT3 had to add some to his, but has already done more track time than I have.
I'm back on track June 2-3. If it still doesn't use up any oil, I'm gonna consider it a tangible difference. Is it because of my break-in process? Who knows. It's all witchcraft.
Im assuming everyone will be different but concurring with the gradual build up over 1000-2000km, keeping revs variable etc. This is manageable, but beading PCCB a bit harder to find suitable location for quite a structured process.
For the record (no science, just what I'm happy with), Ive simplified some of the more detailed recommendations to simply 4/5000 rpm first 1000km. up to 6/7 ..8 ish next 1000km and free thereafter. Ive just completed 480km in first four days and struggling trying to keep under 5.
