Spun my oem crank hub bolt out on my build bottom end build, had 4 people in the pig of a e93 when it happened didn't sound to good. Looking for options and feedback from people who are actually running upgraded crank hub solutions
Well nobody im aware besides maybe ghassan makes a keyed crank so its really not relevant to the n54 anywaysWell, then we have a difference of opinion on that. The amount of material you take away wouldn't be that much and the reduced strength would me negligible.
The most stress on the crankshaft is not on that point anyway.
isn't it very common for key ways to fail on RB'sThe VTT design is far superior vs a dowel pin in my opinion and everyone is entitled to one.
I've fitted about 5 of these now without a single failure including one on my own engine.
Your depending on a little pin to help stop the hub from spinning, seen many keyed hubs fail especially on diesels and they use a much larger
design than this.
Glad its working for you until it doesn't.
As has the splinelock.I guess it depends on the design.
The surface area the splinelock uses is much greater vs a pin or a key type lock.
It's just an observation from the failures I've seen.
The pin design is not bad and is much better than stock BUT THEY STILL FAIL
