Good enough for me. I read it on the internet so it must be true. Please feel free to research liberally if you are looking for more answers and need affirmation.

But yeah, I really just want to know the story of the S55 beyond all uncertainty. Amazing how much mystery this car has provided us, eh? Every time we learn more, we realize still how little we know.
91mm seems correct for the S54 and N52, so should probably be the same for the N54 and N55 as well. And doing new measurements at a larger scale on the N55, I come up with 91,12mm bore spacing...

If so, BMW really has gone to town with retooling for the S55. They MUST have seen major benefits and possibly a long lifespan for the S55 engine
