Injector Flow Formula

Hello Andre,

to calculate CC in the new fuel pressure setup you suggest the formula:

old flow rate x ( {\sqrt New pressure / Old pressure}

In this formula, Pressure need to be calculate to Bar or to PSI pressure? or either both bar and psi with no difference?

And the old flow rate need to be expressed in CC or PSI?

Many thanks

You can use both Bar and PSI to calculate it as long as the same unit of measure is applied to old and new pressure. Old flow rate should be weither in CC per minute or Lbs per minute since these are units of flow whilst PSI is the unit of pressure
