I haven't read ths whole thread, but does it look like 2 air boxes on opposite sides of the engine? Possible electric supercharger?

I guess you can do the exact same thing on with the next gen M3 engine. Plenty of different part numbers that separates it from the engine it is based on.
Bottom line is, those S engines revved like an //M engine is suppose to rev. No N engine was close to 8,000 RPM, let alone 8,250. They were leaps and bounds better than the standard engine. You can tune an N54 to around 400wHP on pump gas now with bolt ons and a tune.
Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
