I have a nx single stage fogger i got used it has NX jets in it that are
Nitrous 57
Fuel 35

I was looking in the stickies and found this
NX Ls1 jetting list from NX website RWHP RATED....GM Stg.1 EFI system, part number 20920

Single jet
50HP 35N 18F
75HP 41N 22F
100HP 52N 28F
150HP 62N 33F


NOS jetting 5168 kit wet for LS1 RWHP RATED 900-1000psi rated
single jet plate system
75HP 41N 28F
100HP 51N 31F
125HP 55N 35F
150HP 63N 38F

I dont understand i have a NX kit but the jets are about the same as the NOS kit....would this make the hp be off (rich or lean)

As you can see my nitrous jet is in the middle of the 100 and 150 on the NX chart(125 shot) but the fuel is more than the fuel jet on the(150) shot....I was thinking it was a 125 shot untill i seen this

What do you think it would be 125 shot,More or Less......

 

N57 is a 125 shot

If he ran it with a F35 he most likely needed the extra fuel for some reason

If you go by your chart N57 and F31 should be close

But the fuel jet all depends on your setup and AFR NA

Whats your AFR NA?

 

use the link in the faq at the bottom of that section....

also, those are just starting points. dont ever just think it will get you right on the money with AF. you need a wideband to make sure it is good.

 

I agree; For the street, I run 57/32 for a 125hp shot
