Is there a mathematic way to convert nitrous jet sizing in terms of fuel pressure?

For instance, stock NOS Cheater jetting for a carb setup is 63/71 for 150 horsepower at say 7psi fuel pressure.

What if I wanted to run 10psi of fuel pressure on my dedicated fuel system? How would I calculate jet sizing?

 

I know of no quick mathmatical way that works for certain. NOS can send you a jet/pressure matrix chart that will give you the info you need. Just call Holley/NOS tech and request that they fax/email it to you. I am sure they use a formula, maybe the tech can help you with that.

 

I agree, the phone tech line was very helpful to me too.
