what happens

been running 61/2 pounds of fuel psi on my nos what happens if i drop it to 51/2 now that i have two regs?will it speed up beening it had to much psi?what a good baseline to start fuel psi at so it will not hurt motor?

that's a SJ question. We ran 5.25psi nitrous fuel pressure with our setup but we ran square jetting in our plate. never burned anything in hundreds of passes and didn't black smoke. of course that was only a 200 hit.

i started out with a 10 jet spread on the plate at 5.5 psi ....

it a edelbrock rpm system and has not been flowed.so if you buy a system what fuel psi is good to start with?
