S55 crank hub video
Interesting video on YouTube...
I had this happen to me about 6 weeks after I had the car (it was stock then) so now I'm out of warranty and Bootmod stage 2 keen for it not to happen again

Great video, on the M3 cutters people are talking about using the Litchfields fix. It's between £300 and £400 and secures bolts around the two gears on the crank hub while also covering the bolt itself so the whole unit has to move as one.
The only problem with fixes like this, Usually when the crank hub goes, in most cases timing slips ever so slightly so that car drives rough with a drivetrain malfunction. However with these fixes, if the crank hub does slip it'll usually result in total engine failure. The Litchfields fix however does look promising so when the extended warranty expires I may consider it. However if money is no issue and you want maximum power, the maxPSI crank hub available on Kies Motorsports is bulletproof. The MaxPSI M4 is running stupid stupid power and there is yet to be a single incident of a MaxPSI crank hub failing I believe. There are also surely some other great companies out there as well as the ones mentioned. |

In video he states "In many cases the valves end up hitting the pistons" Really? as far as I was aware this rarely happens, even on the video of his friends slipping there was no piston contact.

Almost every video on this subject is done by shops trying to create fear/business. If they say it rare for engine damage than majority ill just wait for the .05% chance its gonna happen

I've only heard / seen two cars that this has happened to, and they weren't pretty! Mostly people do just have timing issues

I guess that leaves the Maximum PSI one as the outright best option?

He actually drove home in it!! Was fixed with a different (not sure on the brand) hub, very lucky. I know of another car (stock) that blew on a runway, that needed a new engine.
This guy was running unknown brand hybrids, roughly 550whp - so not insane power |
