He won't be changing the mains unless he takes the box off and gets brave with the cam timing chain....
Leave well alone there! there will have been little to no extra load on the mains from the over rev.\
Oh and some back up from Rich and BMW engine builder we know, 8200 MAX on all the race cars they do.
With the shrick cams they use, the power is at peak revs and beyond but the revs are limited to that for the very reason you have just found out!
Thanks Andy and thank Rich for me, I shall tell the guy I do not need the mains bearings, because I will admit that is beyond me and he is not willing to supply those for free anyway and like both you and Rich (true experts) they should be un-damaged.
Even the guy offering the parts has said he is not willing to do the mains for FREE simply because they won't be an issue, even BMW do not change those out on the recalls simply as they are rarely if ever an issue.
But it is good to hear the same from you and I've already told him the limiter shall be reduced to 8000rpm, not 8100 or 8200, but 8000 where BMW put it.
