I bought a Zex Wet Nitrous kit for my LT-1. I started the installation and noticed that the schematic referenced 53psi of fuel pressure needed. I called zex and they said I need a booster pump. I'm currently running the walboro 255lph in-tank fuel pump. I'm assuming that I could get an adjustable pressure regulator, but that would also entail me re-tuning the whole car to that fuel presssure.

Can i just increase the jet size on the fuel side of the spray nozzle to compensate for the fuel pressure difference (43 psi vs 53 psi)?

Does anyone have any experience with this same setup?

 

you can leave your fuel pressure alone and dial the nitrous A/F ratio in using the fuel jet.

 

i run a 100 shot with stock fuel pump and pressure and have had no problems
