The Peterson R4 five-stage oil pump applies a twisted-lobe rotor design and aluminum rotors to reduce weight while delivering robust pressure and scavenge performance. Its internal scavenge manifold and low-profile screw-in fittings produce a compact, adaptable pump that can be outfitted for varied racing environments, from pavement to off-road, with suitable accessory adapters.
