@ Hustlin Hoosier: No it doesn't but I'm considering adding one to cut down on the flow going to the carb. I'm thinking it just doesn't need this much fuel but I'm struggling to figure out how to size that. Have heard from one friend that a Kinsler 3112 w/ a .100 pill is a good start, no idea where to start with quantifying that though.
1) Does the word "dropping" mean closing the throttle?
2) Can you provide pictures of the fuel system components: pump (as installed), pressure regulator, carb? Can you provide a sketch of the connections between components? What is the displacement of the engine? Gasoline or alcohol?
3) The fuel flow mentioned in your first post would support ~1200HP on gasoline!! Pro Stock territory.
