The Peterson Fluid Systems R4 6-stage oil pump applies a twisted-lobe rotor concept to enable lighter aluminum rotors while delivering high pressure. An internal scavenge manifold and shallow screw-in fittings produce a compact, modular unit. This left-side mount, rear-drive drag model includes front-pressure capability in its description and is adaptable for racing and other high-demand oiling configurations.
