I wo0uld like to see the results as well, I say get 2 sets of nozzles from each of the big 4 , get say a 100 hp over, and a 200 hp over and test each. I would also like to set the parameters for the test as well, test pump will be a single stock cp3 pump, and a single 85% over pump. the test should be conducted with the cp3 running at the rpm it would see when installed on a 5.9 motor turning 2500 rpm. the fluid used would have to be good ole #2 diesel fuel. test performed at say 70 deg f, and an eye on the barometer as well. I say run the test for a single nozzle for 6 minutes, easy to see what 1 nozzle will be flowing in one minute by dividing by 6. longer run time will only make the test more visually different. I know its not only flow, but pattern and atomization as well, but this would be a start.
