Hmm is the information from MAN after sales portal? On
Wikipedia's page the person who edited the page cited the MAN after
sales portal, and it does look like it has the answers to
SMB5888H's specifications. I believe that
SMB388S's specifications can also be
found out from there. The only thing is that a login is required to
access the details.
I don't know how they get access into it, and what is stated in
the portal but I don't expect it to have any answers to
the power rating, maybe just a generic NDxxxF or A95.
Which doesn't give any answers especially when the engine can be
tuned to 320 or 360hp.
