With that being the case (maintaining full flow)...does/would that mean that pressure also might drasticly drop off? As in it wont be able to maintain the pressure ? Because without flow there is no pressure? and with no way of knowing what your Fuel pressures drop of to....(no fuel pressure gauge inside the vehicle) it seems very un advisable to attempt this...even though the part about simply running 59psi of base pressure dosnt concern me as much as the 67psi...
(Again idk if either can be consider safe or unsafe) Im just out of the realm of understanding and experience to calculate the potential ''oopsy's'' maybe this is an experiment that should be conducted on a dyno or so ? Not while daily driving the car ha
Since the injectors also play a big role in how much flow they can handle or how much pressure behind the fuel that is being pushed out of them would a more quality injector put a different spin to the situation?
