I purchased a used NX kit from a kid with a Camaro. I finally got around to hooking it up, and actually just finished wiring it all in yesterday. When I bought it he claimed it was jetted for a 150 shot. When I actually took all the lines apart and checked the jets it had a 41N with a 24F. What shot would that be? His interpretation of a 75?

 

41n 24f is the base jetting for a 75 shot w/45psi (LT1) fuel pressure

base LS1 jetting...please verify A/F
50hp 35n 20f
75hp 41n 22f
100hp 52n 28f
125hp 57n 33f
150hp 62n 33f

 

Well it was supposedly on an LS1 Camaro...

 

each car responds differently to any modification, (nitrous included)

Manufacturer jetting is a starting point, some cars will need to adjust jetting to tune the A/F ratio.
