For the GM nozzle wet kit. LT1 Specific jet settings.

NX only lists 3 jet settings in their generic instructions for the LT1 F-Body, I thought I would compile a list of what I have found by borrowing #'s from other lt1 cars and various searching.

** Disclaimer, you are responsible for verifying these, I feel comfortable with them but don't blame me if something goes bad.


Shot______N20______Fuel
50________35_______20
75________41_______24
100_______52_______31
125_______57_______35
150_______62_______35
175_______73_______41
200_______78_______46
250_______88_______48

 

NX actually suggest 57-35. They are richining it up a bit to keep the hp level down.

The rest of them look ok dave?

 

yes sir.. And 250 is 88-48
Dave

 

I think I'll wait till I get it broke in a little better before ordering those jets

 

LOL,
That might be a good idea..
Dave

 

I don't think you have any idea how much this has helped me!! THANKS!!

 

Glad to help, thats why I put it here. (And so I wouldn't have to keep looking them up either)

Thanks again to Dave too. Everyone buy his stuff, the FJO controller is sweet.

 

The thing I like about these nozzles is that they work flawlessly and make good power w/o having to pull much timing. I run the 150 jets 62/35 on straight pumpgas. With the 200jets but with the 78/41 combo b/c my fuel pressure is up to 50psi and I don't have to pull any timing with mix of 50/50 racegas/93. Later Clint

 

Wow NX suggests a much leaner jetting than NS does. I have my NS wet kit jetted for their 100HP shot and my jets are 46/30. I'm curious how close the HP ratings are in actuality

??????

 

The ratio of the jetting between the 2 different companies. The NX system uses a 52 jet on the N2O and a 31 on the fuel. NS (Nitrous Supply) systems recommend a 46/30 combo. A lower fuel to air ratio is leaner.

I think NX is rating rwhp.... some do rwhp, some fwhp.

No sticky for my

TTT, cause I'm using this info yet again.
