The MM-S2 is the highest flowing pump Boundary offers for the mod motor. It is made for engines running 9,000 RPM or higher. The pump features a billet backplate for higher flow, our patented vane-ported gears, and our MartenWear heat treatment made to withstand extreme racing conditions.

- The pump is hand de-burred.
- Our industry-leading mirror-finished gear set is used
- It is assembled with our Black Series ported gerotor with dual-stage heat treatment
- When closing the pump up, we use our Billet Steel Anti-Cavitation oil pump cover
- Stainless Torx heads replace the stock fasteners
- All fasteners are torqued to spec
- Loctite applied to fasteners to prevent back out or loosening
- Anaerobic sealant applied to critical areas to boost pump up speed and reduce aeration.
- Assembly lubricant applied to all critical surfaces to get oil flowing fast on startup
- Parts are blueprinted and issued with a specification sheet.
