Boundary Pumps Billet Oil Pump Assembly Chevy LS1 Engine 4.8L 5.3L 5.7L 6.0L Billet Gear Standard Flow Vane Ported MartenWear Treated

Our release of the Boundary Black series is to set a new precident in Gerotor technology. These new gerotors feature both our MartenWear super surfaces for low friction and high wear capability along with our industry leading ported gerotor designs.

This new gear has the following features:

• MartenWear and ColdFinish combination makes the surface capable of 13000 RPM surface speeds without wear.
• Ported gerotor greatly increases the surface area available for flow and allows the flow to move straight through the outer gerotor instead of having to go up across and down to pumping cavity.

This has many benefits:

• Less cavitation which reduces aeration and foaming of the oil
• More flow at high RPM
• Less pumping losses
• Less heat in the oil

All assembled billet pumps undergo the following:

• Pump is completely taken apart, all parts under go ultrasonic cleaning, air blast, and hand inspection.
• Pump is hand de-burred.
• Our industry leading mirror finished gear set is used
• 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 blue printed and issued with specification sheet.
