I would need either a new supercharger pulley that is 3.6mm inwards in the direction of the crankshaft or i would need a set of 3.6mm washers to put on all other pulleys. There's also some weight difference that would create some glitches with our OEM-like tunes, I figured that it won't simply work without a hassle. i could be wrong. I end up not installing it since the OEM damper practically looked like new knowing that i don't spend 100% of the time near 8000 RPM and i also retained the dual mass flywheel. |

The ATI superdamper also has rubber (rubber o rings) inside, so that will also dry out / wear / age. But from what I can see they are 100% rebuildable, so it's more like maintenance and it's pretty much a lifetime product. Very nicely constructed I must say.
On youtube they have a series how they rebuild those dampers.

I will try to look for a close oil analysis firm. I'm still at the break-in phase though. The 15w-50 would be more suitable for your application, I chose 0w-40 because my car is basically street driving with some spirited driving and because the design of the rod bearings (2000 S54) was made with a castrol 5w-30 full synthetic oil. The Castrol 10w-60 TWS was created after laps and laps on the track and should only be used for drivers that regularly take their cars to the track and drive very aggressively. In all cases, the 10w-60 is a severely upgraded 10w-40 with a high amount of additives to form an oil that is similar to a 60 weight on 100 degrees Celcius. I'm not saying it's not good to use it, I'm saying that if you use it with street driving you might have bearing issues like i have found in my engine. |

Thanks!. Here is the link to Lang racing's article on their bearing modification.

The oil 5w-30 was replaced due to S54 burning a lot of it before the next oil change and the maintenance interval was set at an aggressive 15000 miles. I agree with you that a 5w-30 oil will cause problems but a mobil1 0w40 probably is better than the original 10w-60 I am grey on this whole subject so i cant reinforce my ideas further. I will maybe try to find an oil analysis to see how the 0w-40 is holding up. |

They change the rod bearings as a bad patch from 2000 till 2003 and a half and changed the rod bolts and rods as well to M11 instead of M10 The oil viscosity change happened in 2001 before they realized the rod bearing issue and is unrelated, trust me, i'm sure of this, basically BMW didn't think that people would outdrive the 5w-30 castrol edge. if you check your engine cover you can still use the 5w-30 if 10w-60 is not available |

Just to clarify that this argument have nothing to do with the fact that the bearings are too narrow for the S54. the lang racing solution is by far the most effective solution at tackling this problem |

Update
I received my Sachs Racing clutch kit yesterday from Germany . Nice looking setup and very light. Can't wait to get installed . Again the key advantage of this kit is it is designed to work with the Dual mass flywheel. I am 100% certain my intake cam bolt failure was related to vibration from the lightweight flywheel. Should have my motor back from Lang Racing around the first week of March . I'm so going through track withdrawal but it will be worth it . Interesting freebie they put in with the kits lol .

Got some pics today of the custom Carrillo rods and the new crank with widened rod bearing journals . Pretty sure these rods would survive nuclear war lol .
