I finally found the time to get my new NX direct port kit on. I plan on spraying 175 through it this weekend at the track. I am trying to get this thing in the 10s before the tranny lets go. I currently have 20 (N2O) and 12 (Fuel) jets in it. I do not have anything smaller than the 12 fuel jets right now. Do any of you think this is too much fuel per nitrous for this? I can step up to either a 24 or 26 nitrous jet. I think those would put me at the 200 hp range. Thanks for any help.

The 12 jets are going to be rich.If this is you're first outing hit it with that knowledge. If you can turn up your bottle pressure, do it.

I thought they were going to be too rich. I have my hands tied over here trying to get jets fast. Thanks for the info.

Well in N.O.S. Fogger i run .28 nitrous & .22 fuel and fuel pressure at 12 psi .and 1100 psi. nitrous for 250 shot . You can ajust your fuel pressure up or down to get your A/F set. I was running lean at 7 psi and set it to 12 psi now it right on. 12.3 A/F mixture wot.

I'm guessing he's running high pressure from the fuel tank. There's no mention of a
standalone. Yes you can regulate the high pressure after the fuel rails.This will help lean the fuel shot. But that tuning needs to be done under controlled parameters.
(Dyno and wideband) then followed by careful track tuning.This is a great way to fine tune. But not something you want to do blindly or without the proper ground work.

I am running the stock fuel pressure. I do have a 255lph intank pump and a fuel accumulator to help with the initial hit. I do not have access to a dyno and wideband over here. I will have to read the spark plugs to see how rich it is.
