as long as it has good fuel pumps...

VERY interested to see how they solve the n54's issues (and n55? i haven't followed that at all). i can only imagine how much fuel flow a tri-turbo S engine would take...

with all that said, i think the tri is the most likely, as much as i hate to say it:
- keep the cylinder modularity concept that (iirc) scott26 posted about a while ago
- s63 - 2 cyl = 3.3L
- major trend of turbo-ing everything in sight

i really wanna see/feel how an turbo S-engine drives...i wonder how much throttle response they'll be able to get out of it. no doubt that's gonna be their biggest priority and challenge in developing this beast (close second are heat dissipation and fuel pump/supply). the n54 with a jb3 does a pretty good job, so the potential is there, but it's still not instant like an n/a motor. dunno if it ever could be. but if anyone can do it, it's M
