The turbo is a single 72, and after this year Brady had a lot of great ideas for next year, meaning even bigger turbo’s. The cam is a John Russin design .as is most of the cams out there today that work, you can kind of call John the father of Cummins B series cams design.
I would give a big credit to Ray Little and his Head work, the head is a work of art. I believe though that he has made a lot of strides in cylinder heads in the last year, and can now take flow up a notch or two .
And last but most important the progressive NX system is most essential.
Ray quoted a guy a duplicate of that engine the other day; this was with all the updates learned, and a few tricks I didn’t have funding for at the time . I believe that this motor with be a true 6000 rpm player, with real power up to that point, and dependable.
