2. All EB have the same max exhaust braking power at max rpm. However due to the way the Pac works it has a bit more braking under 2000 rpm.
^^^ this is why I went with a PacBrake on my 5.9.
It's actually more than just a bit.
The PacBrake and BD are similar designs.
The "Jake", Banks and Cummins are fixed-orifice "standard" designs.
This chart (below) is from PacBrake, but search the Cummins forums and users report the same. Consistent braking at all RPM, versus a significant reduction in braking below redline on a fixed-orifice design.
