This is looking pretty damm cool!! I may have to rethink what I am gonna do next. Damm why have I bought al this turbo crap?!?!!? LOL
So the new blower is much quieter?? Thats what pushed me away from the blower to begin with, the constant whine would have been too much considering I used to drive my truck every day.

I can hardly hear mine over the stock exhaust. Under acceleration, the faint sound reminds me of gear noise or a power steering pump. Nothing like the whine the 112 blower and lightning trucks make.

ok...here are some preliminary numbers....530hp@6400rpm...
comparison #'s
M112 made 10.3psi@3k rpm 3" pulley
R1900 makes 9.4psi@3K 3.2" pulley
112=10.8pis@3800
tvs=9.9psi
112=10.4psi@4700
tvs=9.8
5700rpm both produce the same boost levels 9.8psi
6400rpms same at 10.2psi.
