can a twinscroll turbo really replace 2 smaller ones?
As far as I undersood the only advantage of the N55 is that they combined gas pulses from different cylinders for fast spooling. In the N54 it is only possible to connect 1+2+3 and 4+5+6 ... but maybe with a custom made exhaust manifold it could be possible to do it on the N54...
The same in the X6M engine... 8 cyl in 4 turbo inlet (2 dual scroll)
the best should be 2 variable geometry turbo like in the 911 turbo...
