i am looking for a solid 400 minimum, with the capability to go to 450 if wanted but that is not as important as i have a complete zex wet kit already installed if i want to squirt a 50 shot. I have the basic vortech kit and i believe i will at minimum need to upgrade to the 3.12 from what i searched and read about. I also have a set of 500cc highflowed stock injectors, and a 255lph, and EMU with all the goodies including innovative already installed. Do you think the stock fuel system will handle 400-450 with any issues? Any help or critisism will be appreciated before i blow money, or a motor.

 

I would suggest a Fuel Return system for those HP numbers

 

it'd probably be safer with a return system, though you don't NEED one to run those numbers - it's one of those things where if you're upgrading injectors and fuel pump etc, it'll save you some install $ to do the return kit right then too
