    Question SNIPER N2O Kit with SNIPER EFI. Jetting size conversion help needed.

    Recently installed a Sniper EFI setup on my car, and also have a Sniper nitrous kit that I'd like to use with it. The Sniper plate kit is originally for the 4150 carb. P/N A7001-SNOS. I run a Tanks Inc. in-tank EFI pump, which works great with the EFI setup. I originally had considered using a low pressure regulator, to lower fuel pressure before the fuel solenoid, relying on the EFI return to allow adequate fuel return, as it does now. I've found that I can use the plate with high pressure fuel, but need to know what the conversion rate is to do so.

    47 Nitrous/53 Fuel is what NOS suggests for a 100 HP jetting for carb. What jet would I need for fuel, with 58.5 psi of fuel pressure, to reach the same 100 HP rating? Or how can I find and/or use the formula to tell me? I'm going to eventually up the nitrous to 150 HP, or even 175 HP if possible, FWIW.
