Calculating Injector flow changes from fuel pressure changes by Brian D. Cain (BDC)  Aug 2002 bdc196@attbi.com

* This document is intended to show the formula used for how fuel rail pressure affects fuel injector
* output as well as give an example.

[Formula]

New Flow Rate (cc/min) = Old Flow Rate (cc/min) x ( SqRt of [New Pressure % Old Pressure] )

* To convert from lbs/hr to cc/min, mutliply lbs/hr * 10.5

Example, using a NipponDenso 550cc/min @ 38psig injector at 50psig:

- x = 550cc/min * ( Square Root of [ 50 % 38 ] )
- x = 550cc/min * ( SqRt [ 1.316 ] )
- x = 550cc/min * 1.147
- x = 630.85cc/min
