It is, actually.  Well, many equations. But it's just an air pump, governed by the laws of physics.

I wouldn't think BMW wasted money designing yet another closed-deck N55 based block.
I think, in time, we'll learn that the blocks are essentially the same. And we know it's using S55 pistons...
I bet they are similarly strong.
But sure, going with a larger turbo obviously is going to hurt low end response. |
Then it sounds like one of the characteristics of the n55BTo30 are that its Smaller turbo is giving it much better low end response.... Making it more playful... am I wrong here ?
