The common concensus between OBS and super duty guys is the 1.0 housing is the best. The super duty guys get a .84 housing, which causes GREAT off-idle torque and great in-boost characteristics (ie boost is always on-tap), but the .84 housing produces high drive pressures and a lack of top-end power. You SD guys get an IC to help with the higher egt's caused by this housing too. The OBS guys get a 1.15 exhaust housing, which makes torque suck *** off the line, but causes great mid-top end power. We aren't IC'd, so this 1.15 housing is great at keeping egt's down. But it also takes several seconds to build boost at nearly any speed.
the 1.0 housing always has boost on tap, has better drive pressures, still keeps egt's plenty low, offers plenty of torque off the line, and maintains great mid-top end power. 1.0 housing with ported compressor housing FTW for you super duty guys.
