Crankhub issue is completely blown out of proportion. Unless you tune it's a waste of money. Joe's case is different however as the engine was already out etc.
Completely untrue. My wife missed a shift in our bone stock 2021 M2 Comp (31,000 miles) last weekend and that poorly designed crank hub slipped and jumped the timing in the car. Fortunately no bent valves but we are performing this exact same hub upgrade right now. Had I known about this issue prior it’s the first thing I would have changed out. Might be slightly less likely if you don’t have a manual gearbox, but we do.
Came to the series late and actually watched it in the wrong order ! However it’s so pleasing to see the transformation of the car but also more importantly how happy you are with the results you deserve it be safe out there and enjoy it !
Without going as far as destructive testing, we've found that a lot of hard used S55s back the crank bolt out, hence a capture plate can be a great addition. No defence for that on yours it seems?
Great to see the update and development for the OMP M2 after months and glad that it will be back on the road soon. Now I am contemplating whether I should change my crank hub at 20,000km before it gives problem. But I was told that only modded S55 will give crank hub issue and if I maintain stock form it is unlikely to break.😅
I see you have the 50 year anniversary hoody Joe, so glad to see. I thought I was the only one 😂. I've never seen anyone else in one. I got mine at Goodwood Need for Speed the year before.
If you are doing to the time and effort of dry ice cleaning… coat everything with Bilt Hamber Dynax UC clear wax, it will stop corrosion coming back for years otherwise your car will look worse after the first winter than it did before 👍
So glad to see OMP back on its feet once again! Worth noting that despite the money shift event, this could have happened to the car at any moment, particularly when it was being driven hard and even more so when it was remapped. Anyone looking to properly use and or upgrade their S55 powered M car should prioritise this upgrade before any other for very obvious reasons.
Did you know the GT4 cars run the stock crank hub? Lots of track/race cars run stock crank hub. If you speak to Litchfield/Wrigley/German autowerks they'll tell you that unless going for huge power it's fine stock.
@@samellio that much is obvious as it’s how the cars come from BMW, regardless of whether it’s a road car or a race car. For a race team to replace an engine is nothing, it’s different for end consumers and people have spun crank hubs at stock power and torque levels. There is no harm whatsoever in doing the work before it becomes an issue as the moment it does become an issue, your engine is toast anyway. Bully for all those race teams but if they lose a motor they’ll have a new one in by the very next day.
@@ShogunsDojo the harm is a bill of over 2k which in over 99% of cases isn't necessary. Even if it does spin, it most cases it doesn't ruin the engine. If it were a failure point in racing, it would be upgraded. It's not a failure point. Random people on the internet say to get it done, people worth listening to say it's only necessary when running big power.
Get the full CSF cooling pack (Charge cooler, Heat exchanger radiator, DCT cooler and oil cooler). Seeing as it’s a clubsport build a stage 1 ECU tweak will not over power the car and it’s more than capable of handling the power.
10k miles and the crank hub is shot, absolutely unreal. I do not blame you for using an aftermarket solution to fix it. However, I question the longevity of this solution because of the 4 point drilling into the crank. I would like to see how the tolerances for the drilling was calculated. A minor mistake in these tolerances after a long period of time and it's going to be "explosive". I hope my S58 won't turn out to have such major engineering mistakes as prior engines.
The crank hub is a common issue on the S55, I’ve had two N55’s at 330 whp and never had an issue even with miss shifts (they were both manual) BMW solved that all with the B58 so the S58 should be okay - the Redbull racing brothers did over 100 000 km on 900hp drifting with no crank hub issues. (Yes mods with some stock block parts)
Surprised you haven’t gone for “ a little bit more power” when so much is available with a relatively small amount of work to achieve it ? Are you running standard M2C power 400 and change? Same engine in the M2cs has an extra 40hp. Why not to take that at least…..😊
Having recently been in the market for an M2 comp, I noticed that one of the cars for sale was your first M2 competition as it had previously worn M2 5OMP. What made you buy the second one as I don't recall you covering getting the 2nd car?
I cannot believe how they would design it that spinning a crank hub is even a possibilty. Massive quality issues those years. Luckily it seems these days the engines are getting better again, but now the design department has lost its mind!
