The Peterson R4 four‑stage oil pump leverages the twisted‑lobe rotor design and aluminum rotors to reduce weight while maintaining strong pressure and scavenging. Low‑profile screw‑in fittings and internal scavenge manifolds create a compact, modular unit that adapts to varied engine layouts. This variant supports rear‑drive mounting and flexible accessory arrangements for motorsports installations.
