    Highest revving M50 / S50 FI engine up to date

    what is the highest revving FI M50/S50 engine so far?

    I do rev to 9000 rpm. S50 B32, fully built. Shimless bucket kit. Built engine....

    Anyone revving north of 9.000 rpm?

    Please note that speedo videos are not valid, we need to see data logs, the engine speed logs of the 9000 + revving FI-bimmer engines.
    E36 M3 Euro TT 60-130 mph 4.49 s
    E46 M3 3.6L TT 60-130 mph 4.22 s
    All Wheel drive M3 Twin Turbo
    997 TT

    Thats on a euro motor, not the same for us spec. The cranks have too much vibration above a certain rpm, even with modified oil pumps and aftermarket damners, it will still eventually come apart above 8k.

    Can't you just put the euro crank in the US motor and problem solved?

    LOLOLOL, if that were true it would truely be a miracle it held together for a full second. I've seen money shifts tear our motors up that saw less over revs than that.

    that's what i'm wondering. But iirc euro crank is heavier than US crank, so it has it's problems too.

    Ok so I'm looking at this thread and an American spec crank wasn't balanced for high revs so u have one answer to fix that u have the crank knifeedged build your engine with light weight internals and the then send it off and have the entire engine balanced and blueprinted and assembled all at one time. Which is the only way u will ever see above 9k and at that your lifters will float out beyond that point in whichever u will have to have solid lifters and then u have at least 5k or more in your engine!

    The problem with the us spec cranks are the bad harmonics at higher rpms. Not balancing. My crank is balanced within 0 grams, but will rattle the oil pump apart (maybe more) if I try for 8500 rpms. My bottom end is balanced to less than a gram of each other as well, still not the issue with this crank. boris had to make all sorts of mods to the oil pump, because the crank transfers the harmonics through the chain to the pump and he keeps tearing them up.

    So for guys who want some peace of mind and to rev higher isn't the Euro crank a simple swap?

    Dont believe so. I have never seen or heard of such a swap and there is probably a good reason why. Like, might as well just use the euro block, or maybe just too different. Not really sure, but I'm sure if it were that simple it would have been done before or more often that we know about it.

    You are more than likely right.

    The S50B32 is most similar to an S54, not an S52. Doubtful much if anything is common or swapable between the two.
