I'm talking about these:

From what I can gather borg warner made them for detroit for a few years, now mercedes makes them and detroit "assembles" them for the NA market. From what I can gather:
- axial flow turbine
- asymmetrical exhaust housing (two sides have different a/r)
- there's some sort of flap that directs exhaust flow between the two sides
- detroit claims pretty decent mpg gains, although this isn't the only piece
- they run about 2400 Canadian
Problem is you pop open a dd13/dd15 and there's a huge heat shield covering everything up. You can't even tell if it's a t6 flange.
Does anyone have any specs or compressor maps for these?
