I am installing a Nitrous Express kit I picked up second hand and i am new to the nitrous world. I want to install a 75 shot. The jets suggested for my motor is 41 nitrous and 23 fuel. I have a 41 for the nitrous side but I only have a 24 for fuel right now. Can I run the bigger fuel or should i wait until I get the correct size jet. I am going to the dyno tomorrow and I wanted to have this ready.

thanks for the help

 

You can run it, but it will be rich and you will be leaving some power on the table.

I would run it and check the plugs, and go from there. I have found some of the recommended jets to be a little on the conservative side, I have only dealt with NOS though.

 

^ this, then once its working...switch to a 52/28 jetting lol

 

Well I just got back from dyno and I was happy with what it did considering it was rich. I went from 323 to 387 on a 75. And my bottle pressure was down. the timing is set at 24 to be conservative for now. I am installing the 52/28. or should I go to 125 shot? What is the jetting on that? This stuff is addicting. Not bad for my first try with juice. Oh this is a 4wd also in second gear. Best part is this is a work truck with a ladder rack and tool box.

 

Love the ladder rack, the super sleeper.
There are a few online calculators but Its best to call NX and have them tell you then you know its safe, I was running a 42. 24 on my BMW being a 2.5 6cyl that was around 120 shot

 

P.S. its extreemly addictive, and its best to do your tuning and spark plug checking on a regular bottle pressure say 900psi. 200 psi higher can cause you to go scary lean and 200psi lower will loose quite a bit of power and look extreemly rich. Just keep checking the plugs! they tell the story

 

if you dont have one, get a nitrous press gauge, at the bottle or in cab, this will help to tune properly and have consistent horsepower
