I have a built motor and run svo 42lb injectors. On motor the fuel pressure stays at like 43-44psi at wot. I sprayed 100hp through my nitrous outlet plate and it dropped to 32 psi area give or take a few psi. I want to run 200hp through it, but the obvious is that the pressure wont be there. I have a granatelli 255lph pump thats over 4 years old in it with the hotwire kit. What are my options that isnt gonna cost me a rediculous amount of money?
