The Peterson R4 four-stage oil pump in right-side mount with high‑volume scavenge and front pressure provision is built for demanding engine use. Its twisted‑lobe rotors allow aluminum rotor construction that reduces weight while producing dependable oil pressure. Internal scavenge sections pull vacuum to help reduce crankcase windage, and the shallow screw‑in fittings contribute to a compact, adaptable pump package for motorsports applications.
