Injector ratings....

cummins specs for back of the head return is 180 ml/minute at idle. Thats about 30 per injector. The number is always little higher with truck at operating temp than cold. I did a set of brand spanking new injectors once and cold was 60 ml/minute and warm was 90 ml/minute. The thing is you can't separate the flows out to tell how much from each injector.

doing each injectors individually will get you the back flow rate. Testing at the back of the head will only give you a total.

Garmon's machine will give you that info.
 
yeah, Ty thats what I meant. the number you get from the back of the head is the sum of the 6 backflows. To answer Jason's question I do not know unless so much pressure has to be built up by the backflow before overcoming the valve and actually leaking off, this is only speculation though.
 
Anyone know what the total pintle lift is on a CR nozzle ?
