Flow Increase/decrease From Fuel Pressure Change


When you increase or decrease fuel pressure at the injector from its rated flow you change the amount of fuel that is actually forced from the injector (the injectors volume flow).


New Flow = SQRT(New Pressure / Old Pressure) X Old Flow Rate



Here is an example:

New Flow = Square Root of (55psi / 43.5psi) X 30 lbs/hr flow rate
New Flow = 1.124 X 30 lbs/hr
New Flow = 33.73 lb/hr



Remember the lb/hr to cc/min conversion:


lbs/hr to cc/min
lbs/hr X 10.2 = cc/min

here is an example:
30lbs/hr X 10.2 = 306cc/min



cc/min to lbs/hr
cc/min / 10.2 = lb/hr

here is an example:
306cc/min / 10.2 = 30lbs/hr
