2350 boost pressure while engine braking. - SemiSweet - 12-17-2020

Curious what guys are seeing for max boost pressure under higher RPM engine braking(1800-1900) on cm 2250/2350s. I have seen mine get as high as 40 psi briefly while using the jake.

40 psi sounds excessive. Many ISX's will crest at about about 28~ish psi under full load on highest setting.

About 35 psi when braking. 32-33 psi boost full throttle.

450hp 2350 about the 28 psi mark.

My cm870 would hit 33psi at absolute peak and my cm871 hits 28-29psi.
