Then when you open each injector with a supplied voltage, fill up a graduated cyl and time how long it takes. then you can figure out how many cc/min the injector is actually spraying. I'm not sure how well this method works with our side feed injectors, because I haven't tried it, however it works just fine with top feed injectors.

why would the way an injector feeds matter?
