IME depends on the pump - the older Lucas pumps without EGR are utter rev monsters from my experience, they are happy at 6k+ if you screw out the max RPM screw on top! The later pumps as fitted to the ph2 cars and late ph1s with EGR absolutely hate revving, the VE makes them feel like a different engine - if modified, the VE pump will make them turn until 6k, but fuel is dying off fast!
As stock they *should* touch 5k, if it's not it sounds like your throttle cable is slack or the pump is struggling for fuel.
