Does anyone have any good links for nitrous jet tables?
I have been playing with my nitrous system for the past two weekends and need help with it.

Started with the 100 shot. Jets 55 NO2 and a 42 Fuel. With those jets my AF gauge just pegs 10.
So I then jetted up to the 150 shot. Jet 70 N02 and a 53 Fuel. Same thing happened with the AF gauge.
Next I tried the 42 fuel with the 70 N02. Still to rich.
Fuel pressure is at 48psi.
Should I just keep leaning it out?

Re: Nitrous jetting help.
Your fuel pressure is the problem. You have WAY to much for that jetting. Those jet sizes are similar to what i run on my carbed set up with 6psi.

This site was REAL close for me, and landed me in the mid 11's on A/F.

Are you using a wideband, or narrow band gauge?

I am using a dynojet wide band kit.
I wonder why NOS wants you to run a .070 and a .055. I will be ordering a .038 fuel jet today.

My base NOS jetting was also PIG rich, around 9.6 a/f. The car black smoked, and with a "100" shot jet (47n2o i think) the car BARILY picked up. After i leaned it out, you could really tell it picked up when the spray was on.
