As for LSD port installs there is only 1 main engineer that can install them. BMW is extremely particular about this because when port installed you get a full 4/50k warranty on the LSD and they want it done right. If dealer installed you get 2 years coverage not 4yrs. Not to say that dealerships don't have good mechanics they just aren't all as skilled as the rest. As for break in I'm taking it easy. Haven't been over 4k yet and will just be nice to her for the recommended 1200 miles. I'm patient |

OP, grats on your car BTW !!and I hope you're on the mend.
I see you live in Pleasanton. My bro in law lives there and I visit him pretty regularly. Maybe we'll have a spotting in the future. Last edited by topcat; 01-25-2015 at 07:08 AM.. Reason: Spelling correction |

FWIW - any we know this is controversial
http://www.mototuneusa.com/break_in_secrets.htm The key is loading the engine. Full throttle for 80% of RPM while in 3rd-4th gear, while in the first 20 miles, with engine warm. All my bikes and cars are done this way and personally, I feel like my 328i N26 is much stronger than the loaners with same motor I've driven I personally subscribe to this method on the street. If you're gonna run it hard, make sure it's warmed up and make sure you have space to do it while your tires and brakes wear in.

Whether it because of the break in would be speculation without a tear down of both in a controlled environment, not unlike the testing done referred to in the article. You and I both know that, so stop with the assumptions and semantics. Did you read it? Do you have evidence this article is bogus?

This is the method I've always found to be the best. You want a good load on the engine climbing through the rev-range. WOT in low gears doesn't give the necessary load and everything spins up too quickly. A nice engine load throughout the rev range varying revs gets things working nicely. |

Far more manufactures specify driving in hilly conditions or frequently varying engine rpms and speed. This loads the engine properly when accelerating and decelerating. Mazda specifically states to do for this for the first 200 miles. Verbatim from the BMW Motorcycle manual. Breaking in - Engine While running in the motorcycle, vary the throttle opening and engine-speed range frequently; avoid driving for long periods at a constant speed. Choose curvy, slightly hilly sections of road if possible. It's actually fun to break in if you're in the hills/curves and downshifting going down hill/entering curves and going heavy on the throttle uphills and through the apex of the corner. Doing this while going easy on the brakes.

The gain in HP can be as much as 10%, as tested. That's 24HP from a 240HP motor. If you take the delta between this method and a poorly run motor it can be as much as double. Even with a 5% loss/gain between the 2, that equates to 20HP. There are people doing mods that hope they 20hp from a 240HP engine. The article is a side by side compare and with >300 engines tested. Why not do some research on your own? There are plenty of racing teams that break in the same way. And guess what, they're rebuilding motors all the time. There's a lot of "I really doubts, you can't and I'm not buying" in many of your posts. Thanks for your continued "subjective" contributions.

Mazda does and so does BMW Motocycles. The 2 I'm familiar with. I mentioned this in post #30 above.

The F80/82/83 has required maintenance at 1200 miles. BMW covers the oil and diff fluid change under the maintenance warranty. The DCT cars (maybe the 6MT also) are equipped with a rev limiter that is removed by the dealership performing the fluid changes.
