The injection cycle is shortened to about 40% of a port injection motor is what I read in that. Obviously the exhaust valve needs to be closed, and the injection time needs to stop sometime before BTDC. A port injector can feasibly be open 720 degrees, but obviously not ideal. 720x40%= 288 degrees. At 7200RPM that's about 6.7ms.

Well I guess 'concerned' may be the wrong word.
Does anyone have the flow rate @ Xpsi for these injectors? Since the FP is variable and the HPFP is limited, is there a flow rate plot for these injectors?
Just trying to see what the calculated limits are for fueling.
