Siemens 668cc High Resistance Fuel InjectorThese injectors flow 60 lbs hr at 43. 5 PSI ( 3 BAR ) and up to 85 lbs hr at 87 PSI! In addition, these units are high impedance so no need to add ballast resistors making them compatible with most engine management systems. Despite the high flow rate, they are linear and controllable at low pulse widths and have been used in ULEV applications! This allows you to use a larger injector than normally possible without hurting idle and low speed
