A V8 with 42lbs injectors running at 90% duty cycle needs 190 lph or 50gal/hr. This can get you 600HP NA or 500HP boosted. To make 500HP naturally aspirated, you only need to run the injectors at 75% duty cycle. For a V8, that's 160lph. Looks like you want a 190lph pump. Buy the summit house brand pumps. They're Walbros, just like BBK and other brands that charge you more for the logo.
