N.O.S. Jets
Spreadsheet I came across for calculating N2O jettings.
(for NOS type flare jets.)

Not sure who came up with that chart but it's off by quite a bit. The nitrous to fuel jet spread is'nt too bad but the listed HP is way off. A 46 jet is closer to 100hp then it is 50hp. Plus most nozzles won't flow anything much bigger than a .061-.063 jet.
It doesn't matter if it is a wet kit or a dry kit. Nitrous is pretty much a constant, X amount of nitrous provides enough oxygen to burn X amount of fuel. You have to be careful what you find on the net I've seen some wacky things.

that chart is a little off. i CALLED N.O.S. and they gave me the jets for a 50,100,150 shots on a wet kit with a fogger nozzle. here's what they told me-
50shot- 37N/22F
100shot- 47N/30F
150shot- 61N/33F
the 50 you have listed is the same, but the 100 is a LITTLE off, and the 150 is way off. right now ive got 61N and a 32F because the shop a bought my jets from didnt have a 33 at the time, so im prolly running a little more than a 150.
and BTW, you CAN run more than a 150 on a NOS nozzle. the nozzle has nothing to do with how much you can flow. your solinoids will only flow a certain amount, and that's what will limit you. if you have solinoids that will go up to 100hp, then technically, you could run with NO jets and you're still only going to get a 100shot out of them- dont even question, ive seen it done. i also have friends that have run 175-200shots on a NOS foger nozzle.

And comnbyu- It depends on what nozzle you have. The nozzles DO have limitations, just sometimes the nozzle limitation isn't as low as the solenoid's flow limit. (.073 NOS orifice limited @ 170hp)
I know the Nitrous Works EFI standard nozzle will only flow 100hp. They have an upgraded nozzle that will flow up to 175hp..

that may be true for Nitrous Works, but not for N.O.S. i called on that too. the only differences in the 3 nozzles offered for NOS is the way it sprays, or the distribution. basically, the best fogger they have, is supposed to give off a more evenly distrubuted, denser, fogg (thus burning better) than the cheaper nozzles. that's it.

No you can not run more than 150HP on a single nozzle. The only nozzle that has the potential to flow more would be a 13700A. All the other nozzles have an internal orifice of around .061-.063 or so. The 13700A nozzle has a larger orifice internaly so will support a bit more power but that nozzle does not come in any single fogger kit. But even if you tried to run an A nozzle that big it may be a little harder to tune due to the fact that they tend to pressureieze the fuel side. And the bigger the nitrous jet the worse it stalls the fuel.
My statment was not wrong. Nitrous is a constant period. A 46 jet flows the same amount of nitrous in a wet kit as it does in a dry kit. It doesn't matter if it's a wet kit or a dry kit the same amount of nitrous means you can burn the same amount of fuel.

i didnt say your statement was wrong, i simply said that i called NOS and talked to THREE different people to verify what i got. my above list is what i was told for those particular shots. i dont know about any of the other ones (45,75,etc).
and YES, you can run more than a 150 shot on a NOS fogger nozzle- ITS ALREADY BEEN DONE
so that's not disputable...like i said, it's your SOLINOIDS that limit the shot.
i agree with what you said on the wet/dry thing. the only difference in the two is that the additional fuel is being inducted at different points. the n2o is the same regardless of how/where the fuel is added.

The fact that my statment was not wrong was not directed towards you it was to 11 sec GTA.
The fogger nozzles that come in the kits will not flow anything bigger than a .061 to .063 jet. As I said only the A nozzle will have a chance and even it will have it's problems. You can put any jet you want to in the nozzle that doesn't mean it will flow it. And I doubt anyone at NOS would tell you that you could flow more than 150HP through a single nozzle. Take one the nozzles that is suposedly running more than 150HP take a pin guage and measure the ID of the nitrous passage and see how big it is. I'll bet you find out it isn't bigger than about .063".

Shaun,
I see what you're saying. I was confusing myself between all the different things I've read. I was thinking between 5177 dual nozzle dry kits, etc etc in comparison to my NX single fogger kit.
And as far as the debate about nozzle orifice, you're completely right.
Question for you Shaun (since your a NOS tech)
I've read that NOS recs. 800-875 bottle pressure for optimum performance on your kits. NX recs. 1050. Wouldn't that change jettings between the kits?

COMNBYU,
What NOS nozzle are you using? I currently have a Standard NOS fogger I want to use but the NOS tech said I should use the 90 degree softplume. Do you think the Standard fogger will work for an LT1 setup, It will use a Pro Shot and Fuel cheater solenoid If that effects anything. I want to copy your set up because I have these parts from a Pro Shot kit laying around the garage that I picked up super cheap $$$.
Thanks,
Josh
