| But fuel pressure also affects how quickly the injector can open and close. Higher pressure differential (base pressure) increases the amount of force the injector internals have to overcome to start flowing. This increases the "deadtime" of the injector and needs to be taken into account. | But fuel pressure also affects how quickly the injector can open and close.

| - | To illustrate this affect, we took a set of FIC BM1450s and ran them at varying fuel pressures from 30psi up to 60psi in 5psi increments. The results are shown below. | + | To illustrate this affect, we took a set of FIC BM1450s and ran them at varying fuel pressures from 35psi up to 60psi in 5psi increments.
