Crank hub definitely a hustle....I have 125,000 plus miles and haven't had any crank hub issues....fuel pump and injectors did go out at 110k....have been on a stage 2 tune and 100octane tune for yrs

[@topfueljunkie100]

How much did the pump and injectors cost you? I know they got quite pricy (like $3k) for a set for the N54 so I wondered how bad it is for the S55. Thanks

[@jenningswinfrey8171]

@@topfueljunkie100 wasn't to bad actually, I did a fuel pump too...I had a high output fuel and it was a piece of shit....had to go back with a stock pump and it worked like a charm, plus the high output pump fucked up the fuel gauge level in the car it was off bad!!!

[@BPF80MCar-vi1pg]

That's good to know I'm at 65k and was worries. I did get my crankhub fixed though

Also the n55 has cast internals and the s55 has forged internals and mahle pistons and thats a huge difference when driving these in race applications!!

[@dylanoppeneer2354]

depends what n55. some n55's have forged crankshaft and forged pistons like the n55 m2

Hi Bryce , Stephen Shippy . Just wanted to say hi and really enjoyed your video. Well done! We just sold Logan’s m4 crazy fast!!! Keep up the good work.

[@McoPacMan]

Great video, side note music is a little loud

[@darylmorse]

Regarding the different "versions" of the S55, they all use the same long block and accessories. Other than the use of water injection in the M4 GTS, the difference between them is the tune.

[@andrewrengel]

Spinning of the crank hub comes from mashing the throttle in high gear (5,6,7) and having the kick down feature activate, jumping you to a lower gear (2,3,4). Just avoid this and you’ll be fine (terrible for the car anyways).

[@TheSundaeDrive]

Well done video. As a performance shop that does a ton of bmw work, we normally recommend building the engine if you plan to go past 700ish whp/torque to be on the safe side. It normally takes e85 or meth in combination with a hybrid turbo to get there. Also, while spun crank hubs are less common on unmodified cars, the more power you push the more risk you take. If you are staying stock, probably can keep the stock crank hub.

[@truevhazo4001]

I heard the crank hub doesn’t need to be replaced at 600hp or less.What do u think?

[@diditiu3988]

Hi there nice vid by the way. I just want to ask and since I have a 2021 M2 competition, I decided to change the downpipes, the pipes going towards the back is from eisennman race with no exhaust just a straight pipe with no blockage whatsoever, then I change charge pipes, the crank hub and have the ECU tuned, thats it. Now my question is do I need to change my OEM intercooler to a CSF or any aftermarket dual pass charge air cooler? and I dont track this car but just drive it daily and drive it spiritedly and fast. Hope to hear from you the soonest. Reply

[@hgrigo13]

I think that there wasn’t a 360hp version of the S55. The early M2 used the N55 engine and not the S55. It’s when the M2 competition came along with S55 that they started to produce 410 hp. I’m pretty sure about the engines that were used in M2 and M2 competition, but not sure about the power outputs. Maybe they are slightly less or more.

[@truevhazo4001]

Ur correct

[@dafaqking]

He's talking about the M2 CS Racing which was a non-street legal track car. That made 360 hp.

[@coreyworthingtonii9230]

I have a stock 2018 M2C with 30k miles on it. Hoping there aren’t any issues that will arise, especially with that crank hub he mentioned 🤞🏻

The crank hub issue was rectified on 2017+ models. And even before 2017 it was a rare failure mostly with tuned engines.

[@cwx8]

@@gilgonzalez5902 that isn't true. There are no change to the crank hub assembly.

[@maverickngoose95]

@@cwx8 this is correct. All S55 motors have that ridiculous 3 piece design held together by friction plates and a crank bolt. I upgraded mine to the SSR 4 pin hub on my 2018 F80 as a precaution but my buddy wasn’t so lucky. He spun his hub on his 2017 F80 at about 35k miles. We are both running E85 tunes. He was lucky and only required an upgraded hub. Motor was still good.

[@fnafplayer6447]

That us actually pretty amazing in terms of power figures. Just imagining putting a s54 crank in it and forged internals and a bigger turbo(s) you'd have basically a 2jz.

[@christopherroper9566]

My car dynoed 734whp/676wtq with pure turbos so yeah s55 ftw but this is like the absolute limit you can do on these motors. Any more you are risking the fact you will blow your motor.

[@Anthony-qh1xv]

so, the later N55s have the same rod bearings from the s55. right? 2015 n55? does this mean they will not fail??

[@gilgonzalez5902]

Yes no rod bearing issues on either if these engines and even on early N55 engines it was a very rare failure. My N55 is a 2012 and runs like new at 150k, doesnt even burn oil.

[@codylujan]

"other things" includes leaking top mount intercooler into your cylinders. And by that I mean it can literally seize your engine. I came this close to selling the car 2 months after I bought it because it would always stutter at high speeds and then eventually got to the point where I couldn't drive it at all. I took it to BMW for them to do their stupid fucking multipoint inspection. They told me "all good." Clearly it wasn't. They said, "change cylinders 3 & 6 plugs and coils for $1500." Told them to shove it and give me back my car. The plugs were brand new. Long story short, I wasn't convinced it had anything to do electronically. I then did a ton of research to find out the top mount intercooler will leak directly into your cylinders and cause serious damage. When I finally almost wore myself out, I worked up the nerve to buy a brand new intercooler online and install it as a "hail mary." I even told my family if this doesn't work, i'm done with the car. As I was installing it, there was about 16oz of coolant standing in my J-pipe right below the throttle body. I drained every single drop, cleaned it, shop vac'd it, ran engine cleaner through it (twice) and got all the residual coolant out. Now, it runs like a dream. My point is, if you have a stock S55, KEEP YOUR EYE ON THAT STUPID INTERCOOLER RESERVOIR!! If it gets low, top it off and see how long it takes to drain. If it drains DO NOT HESITATE to buy a brand new metal one!! Those stock intercoolers are GARBAGE! They will destroy your motor!

[@spiraling6980]

I guess its a stupid question but how does it compare to the N54? The N55 was an attempt to improve on the N54 and the S55 fixed all those issues? Im reading that the N54 can take 1,000 hp but the S55 tops out at 750Hp?

[@zimly-gaming1522]

S55 can handle 1000hp aswell, but the crankbearing will most likely spin and you will have Engine failure. If you change the crankhub to an upgraded/solid piece its no problem

[@chrisd2415]

Completely wrong it’s not pre 2016 models it’s all S55 models I know of three post 2018 models that have spun crank hubs, it’s not blown out of proportion quite a lot of units that are running increased power have spun and as that’s most S55 units now then the amount will only increase. I’m speaking from real world experience of this engine over thousands of miles running stock power, stage1,2 and now stage 3 plus at 700bhp with Meth and running 4.9-5.1 second 100-200 times. Intakes do nothing for the S55 in fact most reduce power, even at stage3 stock air boxes with K&N or MMR filters are best.
