i believe those numbers mean the width of the hole in mm? such as 24 means 2.4mm of coarse, you should be able to refer to their website for which jets=which hp numbers they came up with. especially if its a part of a wet kit in which they need to be matched to the fuel jets

Hmm, well i have a NOS system so it may be different. I know i have a 24 nitrous jet and a 28 fuel jet in my system right now which is giving me a 20hp/cylinder hit (160hp), i guess u could baseline it off that, i'll have to bring home my directions from work tomorrow for the rest of the numbers.

Problem is though, NX and NOS do their ratings different or so I've read. Don't want to go screwing up that LS1 with the wrong jets. Best bet would probably just email them and ask for a jetting chart.

NX 52 NX 62 - 35 HP shot
NX 20 NX 18 - 300 HP shot
NX 26 NX 24 - 200 HP shot
NX 33 NX 31 - 150 HP shot
NX 38 NX 35 - 125 HP shot
If I rearrange them in that order what you guys are saying makes sense
18, 20
24, 26
31, 33
35, 38
52, 62
But one set is missing because it's in my car right now.....the 75 HP Jets......
Which my guess goes something like 40, 48....
Just guessing, If no one chimes in here, I have this posted on ls1tech.com and camaroz28.com
NX 20 NX 18 - 300 HP shot

But i did get the information from another board
And I'll post it here just for reference, since i don't know anyone else running a NX kit on their LS1, but it's probably universal for NX kits
NX 62 Nitrous
NX 33 fuel
=
150 HP shot
NX 57 nitrous
NX 31 fuel
=
125 shot
Assuming you are running 60 psi of fuel pressure, stock LS1 setting...

Oh ya and i'm also running a direct port shot which would make things very different also, sorry dude..
They rate mine HP / Cylinder, and i put in whatever that is X 8 and it'll give me my over all HP.. Different for a fuel injection plate system....

Keep in mind fuel jets are rated by pressure. If you have EFI you're running smaller jets than the carb guys.
I found out the hard way. "Man, it bogs like **** on the bottle!"
Oh, and NOS's jet recommendations for efi fuel are nowhere close in my experience.
