HP Rating for 4 injectors on gasoline at 95% duty cycle and 43.5psi relative fuel pressure:
NOTE: Relative fuel pressure means differential pressure between fuel rail pressure on the top of the injector minus the intake manifold pressure below the injector. In a system with a fuel pressure regulator the references intake manifold pressure -- the pressure across the injector or relative fuel pressure will remain constant at all boost and vacuum levels.
NOTE: Holley does not warrant these products as being compatible with Alcohol based fuels, though we have used them ourselves successfully with E85 with intermittent use.
