Anyone know the correct jet sizes for 175hp. I emailed nx yesterday but they havn't resonded yet & I don't think they will this weekend.Thanks.

 

If you are running 40psi fuel pressure, the jets would be 73N 41F. THat would be 175hp. Let me know if you have a different fuel pressure, cause that will change the fuel jet.

 

I run the 73N 41F also for the 175 shot. Works great.

 

Thanks . Hey Custom n20 how do you figure jet sizes based on fuel pressure? The reason I ask is because I have an extra nos dry kit and I been thinking about using it on the first stage(no fuel puddling etc.) and then hit the nx wet on the second. The only problem is I would need an inline fuel pressure regulator for the wet or figure out the correct fuel jet for the high fuel pressure needed for the dry. Just something that's been going through my head. Let me know. Thanks.

 

I dont want to get into tuning the NOS dry kit, cause its a totally different animal. NOS uses much more fuel per nitrous then NX, due to their nozzle design. If you were to run an NX tune with an NOS kit, it wouldnt work. I can tell you that with the race cars I tune, we like to see 1/2lb of fuel per hp. Thats just a ballpark....

 

Cool, but I really don't see why it would't work if the nos system is tuned as if I didn't even have the nx on the car and then added the nx with some way to regulate fuel pressure to it instead of being at the same high pressure needed for the dry kit. Anyway thanks again for the help. Later.

 

My bad, I though you wanted to use NX jets with the NOS kit. I reread and see what you are saying now. Send me an email with your fuel pressure you are running right now, and I can help you out. I can give you any HP with any fuel pressure you would like, in 5lb increments. Can hook you up with jets as well if needed.

does anyone know what the jetting would be for a 125 nx shot

thanks

 

Great, I'll shoot you an email once I get the time to tackle that project. Sorry stik6shift98, I don't have them.

 

thanks anyways sweet94z


anyone know the jetting for 125 shot??????

 

that would be 57N and 33F at about 40-45 PSI fuel pressure.

 

Could you tell me what would be the jetting on an NX kit for the 150 shot? (It really sucks losing your jetting chart) Thanks.

 

NX 150 wet 62 n2o, 35 fuel.

 

Ok, now I need the NX jetting for 50, 75, and 100. Thanks guys.
