No idea, but I bet the atomization is crap. If you're thinking water or meth injection I'd look for a decent, used fuel injector.

At any rate it's easy enough to measure flow at 100% duty cycle. Connect the actual pump you'll be using, and supply the injector 12v for 6 seconds.... measure what sprayed into the glass or graduated cylinder. Multiply by 10. Keep in mind that you don't want to run any injector on a 100% duty cycle for very long. The odds are that it won't be long lived if you do. Under normal circumstances the pressure may be below that of normal operation given that it is only open while the starter is cranking and then only for a few seconds before the sensor warms up and cuts power. I really think you should test with the pump you're planning on using.

Additionally, you cannot use the CSI time switch to control the injector (unless you only want it to spray when the engine is cold and then for only about 5 seconds).
