I think this will harm driveability of this engine a lot.

What I get from reading between the lines with respect to M Division's next generation of turbo charging is that they are really going to wow us. In fact if you compare the S63 V8 to the N63 V8 on which it is based you will see already that they have employed some pretty interesting technology (look at the intake system). And that is just the tip of the iceberg, IMHO. And it accounts in part for the gain of 150hp over the series motor without giving up driveability, and that gain will soon be close to 200hp if the current rumors of 580hp to 600hp for the M5 hold true. Here's what I think we could see:
M5: 580hp 4.4L S63 V8
M3: 480hp 3.0L S55 I6
1M: 380hp 2.?L S20 I4
Flame if you must, but I'll bet you I am not way into the weeds here. It's going to be around these figures, and people are going to be surprised.
