Can't see what's on the other end of the tube, so I can't really comment on how the atomization is set up.
But jetting at the solenoid, seems to be the way of the future. Other companies are starting to go this route (mine included). A lot of the old school, analog duel and triple stage setups are falling to the nitrous controllers.
Other than the reasons you pointed out, Jetting at the solenoids is also beneficial when using a good controller, the proportion in the pulse width and length is damn spot on. So if your setting your controller's duty cycle to feed 25, 40, 60 % your going to get 25, 40, 60% of nitrous and fuel.
In fogger systems (ZEX, NX, NOS...) the lines act like a mini, thin, expansion chamber. Therefore, the metering will change, somewhat, by the time it reaches the fogger nozzles. Jetting at the solenoid allows for better metering cause there is no time for the nitrous properties to change from a liquid to a gas while en route to the jetted nozzles. This is where my system is a little different. I still implement fogger nozzles, but they're not jetted. The jetting is done with a single jet for the fuel and another for the nitrous at the solenoids.
It all sounds pretty minimal. Where it can mean a lot is; when your controller is set to deliver a 90-100% hit, you will get the proper mount through your lines and to your nozzle of choice. But, the track is crappy that day and you back down your controller to a 40-60% pulse width. The power isn't dropped to 40-60% like one would think. Due to the expansion chamber effect and the bore size of the solenoid being larger than the jets on the fogger's end, what you have is a reservoir for the nitrous and the solenoids, instead of feeding, just top off this storage instead of injecting a metered dose of nitrous and fuel.
This will cause you to get more juice than what you wanted when you set your controller. It will be magnified when using large solenoids with small jets, or a long-line nitrous setup.
Once again, not all too bad. Until you look at the fuel side of things. Being that fuel doesn't like to be compressed, so it will stay about what you set the controller. So if a guy starts on a lower power setting, detonation has a chance to occur. Once detonation starts, it's pretty hard to stop, as your now heading down the track. More power will be introduced into the engine and bad things are about to happen. As you know a detonating nitrous setup is not very piston friendly :hitsfan:. The newer setups, that are starting to hit the market are starting to jet at the solenoids in an effort to eliminate this.
Whoa, sorry about getting long winded. in a nutshell, this is the reason, I'm leaning in this direction in my systems.:biglaugh:
