 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. ​ 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.

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