Hoping to take delivery tomorrow here in TN. If not a sale tomorrow, will be a "loaner" for 2 days.
Anyways, how serious is this break-in period. This will be my 4th high performance car (3rd 911) and I have never really followed it -- but this is my first car that cost $140K!!! I just can't imagine laying off some occassional acceleration to 5K RPM or so to stretch the legs.
Keep it below 4000 rpm the first 100 mls, NO full throttle at any time. Then, take the engine up to 5000 rpm for the next 900 mls or so, avoid full throttle most of the time.
After 1000 mls on the engine, you can slowly bring the engine up to more rpm and full throttle. DO NOT use full throttle for a longer period of time (more than 5 seconds or so) before you have at least 1500 mls on your car.
DO NOT use the SPORT button (Chrono Sport) for the first 100 mls (better: wait until you pass the 1000 mls) because it involves the overboost function if you fully press the throttle.
I know it is "tough" to drive such a car and not being able to "make the beast scream" but the above are the MINIMUM brake-in requirements. Since the VTG technology is pretty new to gasoline operated engines, please try to keep the engine at a lower stress level over the first 1500 mls.
I know that there is no real break-in required but if you want to have a problem-free car with a pretty good performance, you should respect the above criteria.
More good advice:
1. check the oil level very often and keep a Mobil 1 bottle with you all the time in the trunk.
2. use the best fuel quality available on a regular basis in your region.
3. stay with factory recommended tire pressures, don't play around with them, they're NOT comfort settings but the MINIMUM settings required for safe driving under ANY driving conditions.
4. do NOT track race your car before you have the mentioned 1500 mls on the engine, the break-in affects also brakes, suspension, drivetrain parts, etc.
And for those who can't wait to add aftermarket stuff to their 997 Turbo, another good advice: WAIT. At least 6-12 months, this not only includes engine tuning but also different rims, suspension mods, exhaust systems and even tires. Unless you want to play the guinea pig and/or ruin the car's (almost) perfect setup.
