At 600% I believe its a control issue, when the needle lifts and exposes the orfices inside tip the fuel is then release so soon that the flow go from a solid mist to a steady stream, but my theory is this... With an extremely large quantity of fuel per shot, more fuel per stroke you have more fuel to move, the needle doesn't just open and shut, the injection pressure is lower but the return spring that controls the needle circuit controls the start and stop of this function regulating the amount of fuel to be injected per shot. IF we move more fuel pershot, like HRT did, then at that point you can have and equal injection pressure I beleive with 400/400s. The problem here I think is oil... Its like trying to move 20 gallons of water through a 1 inch water hose and then trying to shove 50 in the same amount of time... Now we try to move 100 through a 2 inch hose in the same amount of time.. Here again, say the length of the hose is 20 feet, how fast does the water move, and does it come out in a steady stream the same way it did with 50 or 20 with a 1inch hose?? Pressure and volume go hand in hand with orfice size I believe, but my theories may be way off.
