Bolt could have been vibrated loose gradually over time, so it just happened to loosen up now. If this was the case it doesn't matter how much power it made, it could occur stock or modded.

Of course you increase your chance of a SCH with a tune regardless of transmission.

Ok so I've decided to take it to Vargas turbo's instead of performance technic. Vargas supplies the part so it makes sense to have them do the labor as well all for $3500 bucks. Now.. this is all not knowing the extent of my problem. Did it just slip or cause physical damage to the engine? I'm hoping because the car starts and was drivable it's the latter. I'll keep you guys posted later on today.

Well just spoke to the shop and they're not gonna get to my car until next week! Pretty fucking annoying considering that's a pretty important detail to share. Exactly why I just wanted to go to performance technic!!

Ah man.... that's super frustrating and not cool they didn't let you know prior to taking it to them.

Well some good news as I'm msg back and forth with the shop. Was told that if the car starts and is driveable that I dodged a bullet and would more than likely just replace the hub and time it back. 🤞🏼🤞🏼🤞🏼🤞🏼

Wow, ok just got done speaking to Tony at Vargas turbo's and after inspection, codes read I not only spun the crank hub but on the verge of severe engine damage.
To put it in his words "We did not see any more damage, but you got REALLY REALLY lucky the timing was 2-3 teeth off which is a LOT. No engine damage from what we can tell. Count your lucky stars." |

This is exactly why I recommended him a few posts ago not to even let the car idle, let alone driving couple miles to a nearby shop. Just because the car still runs and is drivable after those DME error codes doesn't mean it's ok to run it. |

And after I pulled the codes I didn't turn the car on at all. It was towed right from my garage and thankful I did because yes I could of easily damaged more than just the crank hub. Looking forward to getting her back but this just leaves me unsure if I should follow through with a custom e85 tune I was planning to do.

The general consensus is that the fix is basically 100% effective at preventing SCH again in the future while the bolt capture is “highly unlikely” but not impossible to not spin again. Whichever solution you get, you can also just do stage 2 (tune + downpipes) and pump gas for a while and go from there.

What's the cost spread between CBC and full up hub fix? At this point I would go full monty and be done with it. Then you are free to do whatever you want at any point in the future and never worry about it again.

Think it'll run you the same amount anywhere from $3-4k. To get it done at Vargas turbo's it's running me $3500 including their crank hub fix.

Bolt/plate capture is band-aid solution, not a true fix. A solid, single piece crank hub is the only permanent remedy, as far as I see. |

Correct. The CBC prevents the bolt from vibrating loose which will cause severe engine damage as that means the whole hub will slip. However just because the bolt cannot back out doesn't mean friction of the grip disk cannot be broken leading to a slip, thus the CBC itself is not a full solution you also need a one piece crank hub meaning the timing gear is affixed the hub. The hub also needs to be either pinned to the crank which requires drilling of the crank, or somehow secured aka splined to the crank like the VTT spline lock crank hub. Also note the one piece crank hub itself is not a fix alone either because the bolt can still come loose via vibrations, so you will still need a CBC.
