i've got the standard NOS fogger nozzle. it lists for 29.95 in SUMMIT. like i said before, when i CALLED NOS, the tech i talked to said the only difference in the nozzles was the density/distribution of the n2o/fuel. i will be sticking with my standard nozzle when i bump up the shot. if it doesnt pick up any, than i'll see about another nozzle, but from what ive SEEN, it should work with no problem. im currently running a 150 wet shot on it right now and eventually will ugrade my solinoids to run a 175-200.

btw, i've got the nozzle on the right side of the intake tubing JUST before the TB.

11 sec GTA I can see where the dual nozzle set up could be confusing. But there is a way to take multiple jets and figure what they are equal to in one jet. the formula is like this.


jet size squared, times number of jets, and the square rooted.

So on an LS1 dry kit 100hp is 2 .032" jets. it would go like this-

32*32=1024*2=2048 and the square root of that is 45.25 which is pretty close to our 46 jet for 100hp. I hope that helps.

As far as bottle pressure we recomend 950psi. Anything over 1050 nitrous hits whats called it's critical point which is where it is no longer a liquid. Once it phase changes the flow characteristics can become unpredictable. Plus if you start out at a real high pressure your bottle pressure will drop faster. That being said sometimes the small 1 1/2" guages can read low. So if the guage says 1050psi you really may only have 950psi. But if you have a bigger gauge like an Auto Meter or something you don't want to be over 1050psi. If you have any other questions just let me know.

 

COMNBYU,
Thanks for the info!
One quick question, are the n20 and fuel jets interchangeable?
Can I stick a .028 n20 jet on my fuel solenoid side for instance?
Also would steel brake line work from the solenoid to the fogger so I dont have to buy braided lines?
Thanks

 

unfortunately, i wouldnt recommend either of those suggestions. as far as the jets, heres how it works- on a EFI car such as ours, your jet for N2O will be bigger than the fuel jet because of the high PSI of the fuel. so if you were to switch the jets, you'd likely run VERY rich or may not work at all. this would be because the bigger N2O jet would be on the fuel side (which is going to let more fuel in), and the smaller fuel jet would be on the N2O side (allowing less nitrous). when you have more fuel than N2O, you will run rich, and if theres TOO much fuel, it may not work at all.

as for the line, i would absolutely not use steel line for the N2O. i would buy the braided lines, which are recommended. i know that for the purge, you can use copper line, but even then it's just for a second or two. i heard an explanation a while back why you shouldnt use steel line but i cant remember. my advice would be to use braided.

maybe our esteemed, certified N.O.S. Tech can answer that...

COMNBYU,
I know if I swap the fuel with N20 it will be extremly rich. I will use the jet specs you posted
37/22 50hp
etc.
etc

I meen If I have a 22 n20 jet can I put It on the fuel solenoid side
and jet it
37N20 22fuel for a 50hp shot.
Are the jets the same weather its a fuel jet or n20 jet?
Isnt it the diameter inside the jet, like is a .028N20 jet the same thing as a .028 Fuel jet to interchange them? Im just trying to use what I have laying around here in the garage.
Also what size braided line (-3AN ?)would go from the fogger to the solenoid, right now I have the stainless lines left from the Direct port setup that have 3/16 compression fittings to hook the fogger to the solenoid. I just dont know what -AN fittings will work in place of these.
Thanks,
Josh

 

ok, i dont know if a quite get what you're saying. here's what im getting...

if you take a 37N 22F and lets say you want to bump up the shot later to a 150 (or in this case, somewhere close). you COULD take the 37N from your 50 shot and use that in your 150 shot, which would normally be 61N 33F. you could use the 37N (from your 50 shot) in place of the 33F on the 150 (thus ending up with a 61N 37F), you just wont have quite a 150, prolly more like a 120-130. if that's what you're asking, then yes you can. all of the jets are the same standard flare jets. the only thing that changes them is the size.

as far as the line, i bought kit that came with line, so im not positive. im looking in my SUMMIT right now and im seeing the lower HP kits look like they come with 4AN, and the kits for larger shots or for more HP come with 6AN. looks like my kit prolly came with the 4AN...

Shaun,
I have called NOS 3 times before, and they gave me 3 different numbers for the HP shots... I have THIS nozzle. I need 50, 75, 100, 125, 150 Jets. I need to get a definitive number...

Thanks in advance..
