I replaced the standard (21lbs according to FiveOMotorsports) fuel injectors with 24lb Bosch injectors in my 4.0 motor with the Lucas 14cux because I wanted increased fuel flow with the supercharger, but I may have actually decreased the flow.
The stock fuel pump delivery pressure, per the manual, is 2.4-2.6 bar (34 to 37lbs), but the Bosch injectors I bought from www.fiveomotorsports.com
flow 24lbs at 3 bar (43.5lbs).
So, unless there was an adjustable or rising rate fuel regulator added with the supercharger (it's behind the supercharger and I can't see it) it would seem I'm only getting about about 20.41 lbs ((37/43.5)X24).
Am I thinking this through correctly?
Is the delivery pressure
: 1. The maximum pressure from the pump or
2. The pressure after the stock fuel regulator?
I will check my fuel flow when I finish wiring up the MegaSquirt, but I wanted to see if my thinking was correct for now.
