Over on another list there was some actual testing done along these
lines, and they went to 100PSI with the output predicted with the
"standard" formula ie (off the top of my head) the square root of 
P1/P2.  
  Also the F1 group supposedly runs 5-7 bar.
I would imagine two problems at these pressures, injector seat wear,
and needing to maintain 85% PWM.  I forget the frequency they used
in above testing, but I think they also maintained the 85% figure.
