The Crank bolt worked itself out from the crank hub timing gear. Due to the high revving and power being produced, the timing was is well over normal abuse. The crank hub gear has been a blown motor culprit on multiple bmw N54s 800HP builds, theres an upgraded part out there. See if theres any difference in dimensions on the part from N52 to N54. If so replicate it accordingly. your cams and crank scored once that crank hub timing gear went loose. I plan on a build like this but i will be using the N52 Head & N54 Long block, to avoid having to sleeve cylinders & forged crankshaft. Rods are forged in both motors but would still recommend upgraded ones.
Thanks for the knowledgeable comment. I'm also wanting to eventually do an n54 block n52 head. The odd thing is that this car was making maybe only 300whp at high altitude on the setup. Many people running the ess kit and some with turbo with no reported issues with crank hub that I've seen. That's what confuses me. I like the design and price of the vtt crank bolt catch, but it doesn't look like it'll fit n52. Will have to do more research

Normally the harmonic balancer/crank pulley should have given you some massive vibrations before it totally failed like that. I've never seen that happen before but now it has me super paranoid about my own car lol. Was anything leaking onto the pulley or serpentine belt? If so, that can definitely start to corrode the rubber. Do you follow Vehicular DIY here on CZcams? That's the name of his channel and that guy knows literally everything about these cars and he almost always answers every comment. I would try to show him your build video and this video and see what he says. That freshie is for sure going to last you a long time. I'd be more worried about the transmission becoming the weakest link if you try and squeeze 500 hp out of that engine. I've also heard that you can swap cams from the more robust N54 instead of the hollow cam but I don't know if that is true and/or how much it will benefit you. I would also try to follow the BPC build they did and see what they say. Was it you that said you know Bob from there? Cool video. Thanks for sharing. Looking forward to this even though I wish you would have kept the blower instead of going turbo, but I get it lol.
It gave no warning on here, I was just looking at the belt too as I replaced my AC compressor and did not see any wierd movement while I watched it at it was running. There were no leaks, ofh, vc, oil cooler were all fresh, and nothing dripping. I do follow vehicular diy, I might send it to him to see what he thinks! Good idea. And I was going to keep the Supercharger for a dyno and 1/4 mile, but didn't justify pulling everything, installing a new engine then putting it back on just to sell it after since I'm going turbo. Trans will definitely be an issue at 500+, will be switching to a 335 trans, good looking out . 🙏 Thank you for the comment
the crank pulley is bolted by 6 torx bolts. the hub itself breaks completely loose below around 140ft lbs, which is the same torque for most truck wheels soooo.
Howdy Recently replaced a mini cooperS engine cause of the same issues👎🏿 BMW (&mini) are using this new 2 piece crank hubs that no real alignment lock to them like says of yester with “KEYWAYS” that have worked great for 100yrs but now they have some away with any sort of locking pin, keyway, dowl or any other smart LOCKED TIMING COMPONENTS… That stupid crank snout/hub probably spun, or loosened cause of the superchargers extra load on the crank pulley & loosened that dam bolt= valves into pistons???
The crank bolt comes undone with aggressive down shifting the 335i are known for this there are crank hubs you can buy to lock it in if I were you I would do that.

New engine is in and has a crank hub bolt catch installed 👌
That engine can come out without removing the front clip?
Yes, I've done many this way. It's best to remove the hood
Where are you now with this turbo build?
I didn't end up going turbo. I bought a new chassis and am doing a 300HP+ NA build

good job bro

@@RaimundN52 shit let me know man I got a turbo ready if yal ever do I’m n the group chat with yal
I was there when it blew 😞
😔
Are you going with stock connecting rods and piston
Yep all stock
love it good stuff
Yo can we have an update on the beamer !!!
With the eaton how much hp i can go? And with the turbo whats the goal? The diff can handle?
I have a bone stock 2008 328i automatic, what would you recommend for the first couple of mods /performance upgrades plz respond I’m gonna get a bms peddle tune for the car due to the sluggish take off
Headers, 3 stage intake mani, carbon filter delete, silicone intake elbow, dinan ram mod
How much for the new engine? is it local pickup?
I bought the new motor for $650 with 70k miles, friend hooked it up
Did you get dyno done before it blew up??
I didn't 🙁
rip
time to come back better tho
It will!
Was you able to run e85 ?
Yes
is it possible to build a engine with a n52 head and a n54 bottom end?
Yes, not worth the effort

Yup
