Plus what about the failures that are not reported on this specific forum.
Anyways....
Just got our engine back from Steve Dinan's newly established shop.
Will report back on this project

I believe there was one report of a failure that had a swapped engine in it...

This is a forum, any whistle of something wrong will be brought up.
Seeing as this crankhub issue isn't a trend on the forum can sum up if it really is a common problem or problem in general, as forums have always provided this kind of information..

I personally know of two this year (two cars, 3 crank hubs) ; one of which is on these forums and had his engine replaced with the new bedplate design and then blew it again while on the dyno.

Sorta but not really. I know of my local dealership that has atleast 5 spun hubs at their dealership alone. I'm friends with the shop foreman. So assuming there could be a lot more then what is reported on here I believe

This is interesting since all my friends with different year m3 and m4's haven't had any issues fbo and 30k+ miles and i have two service techs as friends, one from Open road bmw and another at bmw of Brooklyn , both say they haven't seen this issue arise at all.. Weird times i guess..

Like i mentioned, forums is always my go to for common issues trends, and tbh, this forum doesn't seem to have a consistent trend of crankhub issues..
Lets see what 2018 brings us with more owners, more mods and higher miles

I agree what you say. Some dealers see it and some have not.
Just like Dinan in the beginning never got a report of a failed hub from any of their dealers yet, they would only receive info if a dealer was calling to blame Dinan's tune for coverage of BMW's repair.
Also I would assume some people with multiple mods went to their indy shop for repair rather then put to stock and go to BMW

See Gintani is coming out with a new crank hub fix, any info on it? i would like to put pure turbos on my 15 but am not going do anything without addressing the hub spinning problem. Thanks

Why gintani's crank hub is very expensive? 1695 USD
Is it gold?

Spine lock is very different than a Keyed 1 piece or 2 piece solution.

I’m one of those few that received the Gintani from ACM. The car is hopefully “bulletproof” as we say and it feels good knowing there’s insurance in there. Cost wise I look at it this way...Gintani is known for high quality products and was recommended for this project. A few bucks here or a few bucks there saved on another product/company isn’t going to sway my decision when I have a car with a lot of time and money invested in it already. Sometimes you just have to cough it up when there’s a good product accompanied with that manufacturers good history.

Not to stir the pot but back in the e92 days, weren't Gintani terrible when they first introduced their tune and supercharger? Never did buy a e92 so never followed that drama after that, but that has me biased against them. What's changed?

[f80_sturmgewehr]

Besides Dct kick down are there anymore ways of driving a DCT that can result in this issue? I have seen "aggressive Dct shifting" being mentioned a couple times as on threads but I don't know what that means if it isn't related to kick down.

It is all speculation at this time. Speculation that the fault is related to driving style, mods, or transmission type.

Could be a combination of all of the listed factors in addition to tolerance in manufacture parts or installation error.

If it was just DCT kickdown then we would see many more failures.
If it was just higher power engines then we wouldn't see pure stock failures and we would see more failures on tuned cars.

So with so many threads relating to the subject and all the drama/history. who is the winner or what is the rank. obv tpg in last followed by oem. I'm aware of vargas, gintani, maximumpsi, and dinan having solutions to this problem and some being easier to install than others. I just want to go fast...

I'm personally going with the Vargas one, as that's the one my tuner is putting on his car, and right now its 50 percent off for cyber monday

it's not really the cost of the part that bothers me. It's the labor cost that is crazy. $800 to $1200 for the Spline lock vs $3200 for the drilled crank hub solutions.

ya that's a huge difference. I've been quoted 600 for the spline lock install, and just ordered it for 400. So I'll have paid 1/3rd the labor cost of one of the other solutions for the part and labor.

I couldnt imagine spending almost 5 grand on an inferior fix
