I was wondering if I would be able to run the fuel side for the fogger off of the fuel rail running stock high pressure.i have a cammed ls1 ls6 intake with nx fogger kit with pirinha nozzles. Running induction solutions noids. Look at a 150 shot. Nx said I needed a 14f with 22n jetting. Does that sound right

No you can't. The jetting on your fogger is setup to operate on low pressure fuel system. You need to put a stand alone fuel cell on your car to supply the fuel for your system. With that 8 jet spread I would probably start about 6.5 psi and tune from there by reading your plugs.

I do not have any jets yet would I be able to get jets to run off fuel rail.

They have jet charts right on the Nitrous Express site for what you are wanting to do. No reason you can not run high pressure on a direct port system. Nitrous/Fuel ratio does not care how you get it just as long as it is at the right ratio. I would make sure you have a very good fuel filter setup and run a fitting that has a built in filter right before fuel noid. Would probably be easier to tune with 45psi gives you more options to clean up your tune.

I think your better off going with a stand alone so you can fine tune with fuel pressure. And you don't have to worry about not having enough pump to support both car and nitrous. That being said, I would set it up for low pressure. I am currently doing this on my direct port. A direct port pilled for 58 psi will use a tiny jet.on a 250 shot. We were at a 14 fuel jet on mine with a 28 n20. With a 150 you might end up at 12 or less. That's .012 diameter. About 6 hairs bunched together. Any obstruction at all in the fuel jet, and that cylinder is toast. Just my 2 cents.

Damn more money. Should have stayed with the single fogger in air intake

As long as you have enough fuel pump to supply the volume you can pull from the rails.

Another issue with such a small HP setting at high pressure is that your fuel jet is already very tiny and you do not have many options smaller to lean the air fuel out if needed. Which means you would have to up the nitrous pill if it needs leaned out.

We suggest a 24 nitrous/ 12 fuel at 55psi for a 150 hp tune up. The smallest fuel pill we offer is a .009 jet.

What does your fuel setup consist of right now? Also do you know the state of current tune perfect, lil rich, lil lean, etc?

why not pull from the rail but throw in a regulator before the fuel solenoid to drop pressure down.. just a thought

That's what I was going to do

Tune is rich now going back to tuner to finish up tune. Right now walboro 255 intank to corvette filter regulator combo deal pushing 60psi to rail filter is non adjustable. 6an line tank to rail hotwire kit to install stock injectors. I have a set of 48lb on the work bench if needed. Just scored on a stand alone system with progressive tank opener noids lines 1 gal Al cell and pump.
But wondering would yiu be able to regulate 60psi down to 6-10 psi to run off before rail

What do you suggest for jetting for a150 shot stand alone low pressure system on the fogger
