Congrats to all awaiting delivery of their '10 GT3/RS. With the exception of a PCA member on the eastcoast (NNJR) who took delivery at Stuttgart and drove the Nurburgring after 500-1000 break-in miles keeping revs below 5000 rpm what are new owners doing in terms of breaking in the new car's engines?
I intend to do 500 miles with the rev's below 5000 then take it to redline gradually over the next 1000 miles before tracking the car.

Below 5k rpm for first 1000mls, change engine, transmission and differential oil at 1000mls. Still take it easy and only occasionally redline before 3000mls. Then it’s time to go to the race track.
Seems like a long break in, I hope to take it to the track after a 500 - 1000 mile break in after I change all fluids. Should I wait longer??

According to my sales guy and his rep today, the RS's are awaiting certification (EPA, etc.). So delivery to dealerships won't be immediate. The other cars (currently certified models like Cayennes and Panameras) that were on the same boat have been released (PDIMON status). The RS's are not in this status yet.
That's what I'm doing...500-1,000 miles, then hit the track

1. Start the engine.
2. Draw in the fine aroma of that new interior.
3. Warm the engine over several miles driving gently.
4. Begin 2nd and 3rd gear deep throttle (80-90%) roll-on's to about 10% under redline. Preferably while going uphill. 5-10 of these if possible.
5. Bed the brakes as a side benefit of the engine break-in procedure above
6. Rinse repeat over the next couple days and going all the way to red-line.
If all goes according to plan, car is 100% ready for track flogging and mileage is about 500. After 2-3 track days (8-12 sessions), change the oil for the first time.
My cars always run great and have very low oil consumption. The initial 100-200 miles is the critical time to seat everything in the top end of the engine and keep it from being an oil burner. Aggressive break-in also results in engines that make the best power.
The true things to NOT do during break in?
1. Never ever lug a new engine in a high gear, it kills the rod and main bearings.
2. Driving hard before engine is warm.
Lugging and big throttle before oil comes up to temp kills more engines than anything.

Ditto here. Ugh.
I break-in all my cars the same way:
1. Start the engine.
2. Draw in the fine aroma of that new interior.

I think he means bring the car to near redline with near full throttle a couple times to seal the piston rings, so no oil burning in the future. I think this works from my own experience.

Really the first 50 miles is key to load it up under hard throttle ("trottle" if you are from Brazil...lol).
The reason to do it again on successive days is to allow for several heating/coolig cycles of the engine and further mate the moving parts.
How do you think racing engines are broken in? Driving the race car for 5000 miles around a track? Think about it...
*Warm the oil to temp.
* Don't lug it.
* Drive it like you stole it.

When I visited the old Porsche factory in 1986,1992, and then 1997, the engines were all ran in for the first 30 minutes on the dyno before they were deemed ready to install in the cars (911 production line). Then after the car is built it would be driven about 10-20 miles by the factory test driver who evaluates the systems as quality control before delivery to customers. I had picked up 3 new cars at Zuffenhausen and each time the advice from the technician was to keep the revs down below 5000 until mileage has exceeded 500-1000 miles. The advice was also to not run at any steady rpm but to vary the loading to seat the rings. DEFINITELY not lug the engine in high gear as Savyboy said. So I assume the initial run-in has been done for these engines as well (Motorsports engines based on GT1 engine). I doubt Porsche today goes through the same quality control for the regular engines (street cars) in the 996, 997, M96 and 91A.

Do NOT take it easy the first 100-200 miles. Those early miles are the one critical opportunity to get the engine broken in early and well. In fact, unless some weird circumstance prevents me from doing so, on my first drive once oil is up to temp I go deep into throttle in 2nd/3rd gear multiple times. Slow down alternating under engine braking and brakes during different pulls.

Why some here are suggesting that changing fluids ( tranny, gearbox) in addition to engine oil,after the initial break in on cars when the engines are run on dynos for several hours? and Porsche does recommed tranny/ gearbox fluid change long down the road after racking up many thousands of miles?
