My pump has 9.5 mm elements. On a test bench it delivered 180 cc/1000 when the rack was pushed to the stop bt hand (governor removed). With the governor controlling, it could deliver something like 170 - 175 cc/1000 - that is with a modified torque cam.
The injection pump on my 4BD1T doesn't have a boost compensator, so when it was calibrated to maximise the fuel delivery rate, the profile of the torque cam was modified, particularly to try and prevent black smoke at low speed when boost pressure was not so high.Do tell, I seem to recall you mentioning that before, but I don't recall the mods in question.
The torque cam, in conjunction with the full load stop screw, limit the travel of the control rack - the cam is rotated by a lever that is moved by the flyweights as rpm increases. So the cam profile determines where the control rack stops at different rpm.
The mechanical stop at the end of the rack is only for cold start, when the torque cam is bypassed.
