Description
A dry-sump oil system demands a pump that can reliably manage pressure and scavenge cycles without compromise—the Peterson R4 delivers exactly that. This 4-stage unit offers the flow rate and pressure characteristics needed for sustained high-RPM operation, whether you’re running a dedicated race engine or a heavily modified street build. Bellhousing mounting keeps your engine bay layout clean while the lightweight aluminum construction minimizes rotating mass.
