Nitrous Outlet Stand Alone Cell Questions
I have an MSD NX Direct Port setup with a NO Stand Alone Cell. What should the cell pressure be set at? Do I have to change cell pressure when changing jets?

Our Dedicated Fuel Systems are capable of running both high or low pressure. Anytime you change the jets in your system you'll need to re-flow your fuel pressure through a flow tool. To determine what your flow jet size should be, you'd use this formula: Jet X Jet X Number of Jets= J. The square root of J is the jet you'd need to use in the flow tool to set the fuel pressure on the dedicated fuel system.
Many manufacturers offer a choice of high or low pressure for jetting on direct ports. If you have the high pressure jet kit, you'd need to make sure the fuel pressure regulator has the high pressure spring in it. If it's jetted for low pressure, you'd need to be sure the low pressure spring is in the regulator. You do this by removing the 4 hex head bolts from the regulator and pulling the top off it. Inside there is a diaphragm and a spring. The spring that is much sturdier than the other is the high pressure spring. Make sure you assemble the regulator the same way it came apart or it won't function correctly.
Let me know if you need anything else- I'll be more than happy to help you out!

What if I set the regulator at the stock fuel pressure of 58 and go use the jets based on 58psi?

Fuel Jet x Fuel Jet. For example, if your jet chart called for .012 in the fuel side the equation would be (.012 x .012) x 8 = X. The square root of X would be the size of fuel jet you'd need to flow through to set your fuel pressure. You can use 58 PSI if you want, you'd just need to be sure and set the flowing fuel pressure accordingly.

Do you have a jetting chart for direct port set up? I found one but it doesn't have a fuel jet size for 100 or 150 shot.

Here's the jet chart that you'd need for that system:

It'd be hard to say what that systems jetting will be at 150HP, but you can usually get pretty close by splitting the jets from 100-200.
