Need help with NX jet sizes....Anybody?? Ok, here we go.
I have a NX wet kit on my car and had problems while running a 100 shot at the track with it popping out of the exhaust. I believe it's running too rich with the jet sizes I'm using. It ran great with a 75 shot but not 100 and I didn't even wanna try a 150 with it popping. I've been told my jet chart isn't right
but I emailed NX and was told it was right. Then someone on ls1.com said according to NX's tech line my 100 jets are wrong? So NX basically said it was right and wrong Can someone help me figure this out before I go nuts here?
Here's my chart:
HP N20 FUEL
50 33 18
75 41 24
100 52 33
150 62 35
Anybody?

Re: Need help with NX jet sizes....Anybody?? Just got off the phone with NX. 100 shot is 52 N20 and 28 fuel. I am going with a 125 shot. 57 N20 31 fuel.
BTW my chart says a 100 shot is 52 31. Are you looking at the right chart. a 52 33 is way to much fuel.

Yeah, I'm sure it is the right one. I have it right here in front of me and it says along the top:
"GM STAGE ONE FI LS1"
Plus I emailed NX and sent them a scan of my chart and they said it was right
Re: Need help with NX jet sizes....Anybody?? Sorry for the confusion. Just you say your chart sais. 52/33 for 100 shot. And he said on the phone they said 52/28. Then they also said your chart was right by email and so was his? So which IS right? LOL
I'm dumber than i was before i wrote that. HAHAH Ill just go by what my chart sais untill i dyno.
50hp 35/18
75hp 41/22
100hp 52/31
150hp 62/33
Just bought my kit this month. And it doesnt pop if that helps you.

Re: Need help with NX jet sizes....Anybody?? My chart says 52/31 also. IF you call and ask what jets for a 125 shot they will tell you 57/31. If you look at the ratio's for the other shots of fuel to nitrous then the 100 shot should be 52/28.
