Dave, the pressure increase calculation isn't correct, the right formula is:
sqrt(new pressure/old pressure)*old flow=new pressure flow.
So this means that 36 lb/hr @3Bar injectors will flow 41.5lb/hr at 4 Bar.
Flow increase isn't linear with pressure increase, otherwise it would be
easy to install 3B injectors and run them at 5 Bar for 600 HP....
Siemens or Lucas 37lb injectors should be fine for you, they flow exactly
9% more fuel than RS2 injectors at 4 Bar rail pressure and RS2 boost levels.
