    You can make a high revving turbo motor, there just isn't a point and it sacrifices drivability greatly.

    There's enough to make a 3.2-3.3L N54 by slight overboring given what my race engine shop said that build my cylinder head..

    Sorry, my bad, N55 is open deck. I was thinking of the M54 for some reason.

    From the pics shown those water intercoolers will do a great job and provide the shortest path possible from the turbos to the intake manifold making for best possible throttle response.

    Bettet yet (for production cars) - the McClaren MP4/MP4-12C is a turboed V8 revving to 8500 RPMs. I would love to drive that thing (or the F1 car) Click here to enlarge

    If it has Valvetronic, which it likely will, it will be more closely related to the N55. Changing the number of turbos doesn't really matter. They could be referencing either 335i.

    This is at least realistic. Except for the N54 bottom end part, new internals and a closed deck mean really nothing related there other than straight six layout.

    At this point I wouldn't be too surprised if it was just an N54 with an upgraded FMIC, RB-copy turbos, high flow downpipes, the Performance Exhaust, and an M badge on the plastic engine cover...

    What is the advantage of valvetronic?

    plenty of reason, valvetronic for one?

    and since when was it TT over triple?

    It's basically for fuel efficiency. Makes the valvetrain heavier. Hence why they never incorporated it on anything truly high revving.

    this sounds about right imo, but it will make peak power at 7000-7100 i put money on it lol.

    i'd say 3.2 not 3.3, hark back to previous M3's

    do you really think they would do such a complex setup? how difficult would this be to tune in the aftermarket?
    the current top diesels (335d) are triple turbo, but slightly different lol

    We'll see..in the aftermarket i'm pretty sure it'll be the first thing to turn off lol Click here to enlarge
    if they do it it will likely decouple when the real turbos come on song from factory. as it (if it comes in) will provide boost from idle, just a couple of PSI at most i guess.

    Or a guy with a UGR Gallardo. Or a McLaren MP4-12C owner. There most certainly is a point.

    LOL...according to the other forum's so-called insider.

    Still don't see how they are going to shed 250+lbs from the F30 335i. Where is the weight savings coming from? It takes a lot to drop that much weight from a modern car.

    hasn't broken in the N52 or N55 yet

    it shouldn't be as bad as say... vanos, as it's just infinite variable valve lift

    what people have done with N52 racecars is remove the valvetronic system and lock it to max lift in the tuning, still works fine hah

    I don't see how either. We will be lucky to get 35XX and I'm doubting 50/50 will be achieved.

    the only problem with turbo motors revving high is having a large enough turbo to flow up high while maintaining good spool characteristics

    this could be where the small electric turbo comes in play, for the low low or. i dunno.. they're in the know, i'm sure they're not going to release $#@!ty m-car. it's their flagship sports car. i have hope still lol.

    they only have to make mid 400 crank hp (so 400 or a bit below at the wheels).. the N54 can make that on stok TD03 twins without punishing itself too hard, it should be a total cakewalk for BMW imo.

    i'm assuming a much better flowing head, as most M's are, which helps with both threshold and efficiency of the turbos... plus a great intake setup and decent downpipes

    The article speculated at more composites based on what the i3 & i8 concepts did. Wouldn't be too surprising to see more carbon fiber, 250 lbs is still a lot of weight though...

    People keep saying carbon fiber, blah...blah...blah.

    The current M3 carbon roof only saves 11 lbs vs standard roof without sunroof. You can make the roof, trunk, hood, etc carbon fiber. It just doesn't add up. 3,300 lbs is a pipe dream.

    If BMW makes the engine out of carbon fiber then MAYBE.

    All this speculation is ridiculous. People thought the m5's s63tu would be a basic version of the n63. It wasn't. People thought the m5 lost all credibility when it went to tt. It didn't. Regardless of how many turbos or what turbos the new m3 will not be close to the n54 not n55. Thinking from a sales point it would be stupid for anyone to purchase the m3. Thinking in terms of the new 5 series; a bolt on 550 is in the mid 400's with a tune. The m5 is in the mid to upper 500's. I expect the same for the m3. BMW knows the m3 sales are falling. The x6m has better sales. Lastly they will more then likely keep the 3.0 displacement or bump it to 3.3 and not 3.2. Simply because the s54. They will not rename the new m3's engine s54. It has to be either s53 which makes sense if its 3.0 or s55 if its 3.3 and loosely based on the n55. Even s56 works but I'm sure it's saved for a future platform. First time I could think of when BMW has ran into this issue. Realistically going off bmws past this is how it has worked.
