Your right F350camper
I have several pumps that put out 3500 psi @5.5 gpm with the pump turning at 3600 rpms. No matter what nozzle I put in the end of the hose or no nozzle at all the gpm will remain the same as long as the rpms on the pump remain the same. My assertion was based on a constant, if I increased the rpms of the pump that would produce higher gpms no matter what the nozzle was rated. Demand pumps will cycle on and off to meet a preset flow rating and by increasing the amount off back pressure required to cause the pump to cycle off it could flow more water through a nozzle thats rated at lower pressures.
So basically I was wrong, but right in theory I hope . The bottom line is you have to check your nozzles with your pump to truly find out what amount of water is being pumped into your engine and changing anything will change everything:Sly .
My nozzle is 3.9gph or .065gpm which is half of what your using. I don't feel any seat of the pants difference with straight water and since I don't have a pyro gauge yet I don't know what drop there is in egts.
I turned up my fuel rate for the extra tq, I added the injection to keep the added fuel from raising the egts too high. I do feel like it pulls the hills easier when I used water/**** window washing fluid.
