I want to learn more about fuel pumps incase I run into the issue of needing a bigger one in a couple months. What does a stock 03 Mustang GT fuel pump flow at and how high do you think it can go, hp wise, on a NA motor? Im interested in doing a head swap but before I do it, I wanna make sure I have all the grounds covered. The car will have a full exhaust and intake, and probably either #24 or #30 injectors. What would a good fuel pump be that could get me up to 400hp if the stock pump won't? As far as fuel goes, will I need anything besides injectors and the pump? I know the car will get tuned after, but what is needed in just the fuel system to support 400 NA horses? Thanks for the information.
