just got my nytro. and was going to start mocking up my nitrous system.(nos fogger system) well there is not to much room to put all the solenoids and nozzels. I want to run a small shot (25 hp). I want to run off the factory fuel pump to run the fuel side of the system. but the problem is the factory system runs 35-40 psi and my fogger system is set to run at 4 psi. so do I switch to a diffrent system. diffrent jets. or put a fuel presure regulator before the fuel solenoid. I was thinking some sort of a dry shot and add fuel some other way.I want to keep it simple as possible. thanks for the help.
 
You can install the nozzels on the side(s) of the airbox (dry spray), add a fuel controller to increase the fuel when spraying...

Same set up as a boondocker kit...
 
The fuel solonoid will hold all that pressure, the bad part is when you don't have enough fuel pressure and you run it lean. Start rich on jetting and go down from there. With the NOS brand, I would always stay 2 sizes bigger on the fuel.
If you are running the fogger nozzles, you want to have those mounted in the carb boots or in the airhorns if you are using the fuel side of the nozzles. Otherwise you can spray dry and figure another way of doing it but that sounds like a lot of work.
Holtzman has a fuel needle valve with their system, but he also has a jet going into each carb boot for even flow of fuel, not that 1 cylinder gets lots and the other gets none.
 
would I need 2 nozzels for dry spraying or just one in the upper left corner facing down (if you were facing the sled)to fog the air box or the lower left facing right. I now wish I would of went with a diffrent system.

IMO I would go with 2 nozzels to ensure an even spray thoughout all carbs
 
Just found this again, jetting for the fogger nozzle.

I know there was someone else that called and they made some little changes as this one in from 2000. I still use this today with the kits that I have installed and no problems.
