My aeromotive ss pump has been 1.36 sixty foot and 10.11 et so 525hp I'm not buying that.Fuel pressure guage is rock solid.Carb only has 95 jets square.
Hard to argue with results so I won’t. I just published what aeromotive lists as the specs. I’ve always sized fuel pumps for more than I need rather than just enough.
Are you on gas or e85?
