High-performance Oil Pump For F-150 (2018-2020) Race Flow Oil Pump Assembly Gen 3 Coyote V8

Boundary Oil Pump Upgrade For Ford F-150
(2018-2020)

Ford's third-generation 5.0L Coyote V8 — as found in the 2018–2020 F-150 — was a significant engineering step forward over its predecessors. New cylinder heads, revised intake, improved fueling, and more power from the factory. The oil pump architecture also changed, which means the 2011–2014 pump solution doesn't cross-fit, and the 2018–2020 Gen 3 engine demands its own dedicated assembly. That's the CM-S1-R2-F150: Boundary Pumps' S1-tier Race Flow Billet Gear pump built specifically for the Gen 3 Coyote in your F-150.

The engineering philosophy is identical to the Gen 1 version, adapted precisely for the updated housing geometry and pump architecture of the R2-generation Coyote. Same billet chromoly gears. Same ColdFlow surface hardening. Same hand-assembly process. Same 9,000 RPM and 2,000+ whp pedigree. Different fitment. Right pump for the right engine.

Gen 3 Coyote: Why the Pump Matters More Than Ever

As F-150 builds push more power through the Gen 3 Coyote — whether through bolt-ons, superchargers, turbos, or full engine builds — oil system integrity becomes increasingly critical. The factory pump was designed for a production engine with a defined power ceiling. Boundary's CM-S1-R2-F150 removes that ceiling from the oiling equation entirely, delivering pressure stability and flow consistency that the stock pump simply cannot match under race conditions.

The billet gears don't flex under load. The ColdFlow-hardened contact surfaces don't wear like cast iron. The matched-set machining tolerances hold volumetric efficiency at RPM levels where OEM pumps begin to lose their edge. If your Gen 3 F-150 build is serious, the oiling system needs to be serious too — and this is where that starts.

Key Features & Benefits

• Stainless Torx fasteners, Loctite applied — eliminates the risk of fastener back-out under sustained high-RPM vibration

• Anaerobic sealant at critical joints — faster pump-up, reduced aeration, improved cold-start oil delivery

• Assembly lubricant on all critical surfaces — protects the engine during the most vulnerable moment of any build: the first startup

• Includes billet crankshaft timing sprocket — upgrades the full oil-drive circuit for a complete, race-ready solution

• Blueprinted and shipped with specification sheet — documented precision for every unit

The Assembly Process

Boundary doesn't just drop new gears into an OEM housing and call it done. Every CM-S1-F150 starts with a complete teardown of the OEM pump. Every internal surface is ultrasonically cleaned, air blasted, and hand-inspected for wear or damage. The housing is hand de-burred to eliminate any sharp edges or casting irregularities that could introduce turbulence or cause premature wear. The billet gears go in, the housing closes with stainless Torx hardware, and the entire assembly is torqued, sealed, and lubricated before being blueprinted to a specification sheet that ships with every unit.

This is the kind of attention to detail that most production parts never see. It's also why Boundary-built pumps survive conditions that destroy stock units — and why builders running serious power trust them.

Pump Add-on Options

1. MartenWear Heat Treatment: 

MartenWear Dual-Stage Heat Treatment: The MartenWear process produces a martensitic surface structure on the gear faces — the hardest, most wear-resistant microstructure achievable in steel — while preserving a tough, impact-resistant core. Competing treatments produce harder surfaces that are also more brittle, or tougher cores with shallower case depth. MartenWear is engineered to hit both targets simultaneously. For a gear spinning at 9,000 RPM in a race engine generating significant heat and loading, this is the treatment that makes the difference between a pump that outlasts the engine and one that degrades over time.

2. Drag & High RPM (S2):

If the S1 is the race-proven baseline, the S2 is what you build toward when the baseline isn't enough. This is Boundary Pumps' full S2-tier treatment for the 2011–2014 Ford F-150 5.0L Coyote: every upgrade the company offers stacked into a single assembly: patented vane-ported billet gears, MartenWear heat treatment, and a billet steel back plate engineered for maximum flow at extreme RPM. Built for engines running 9,000 RPM or higher. Built for the applications that need every last advantage the oiling system can provide.

The stock pump back plate is a casting, which is functional at factory specs, but a flow restriction under high-output conditions. Boundary's billet steel back plate is machined to tighter tolerances, eliminating casting irregularities from the pump's rear flow path. The tighter fit reduces internal bypass and increases volumetric efficiency, particularly at the RPM ranges where a built engine operates... and more oil gets to where it needs to go.

S1 vs S2 - which is right for you?

The S1 is the right choice for high-performance builds that push hard but stop short of all-out race territory: supercharged street/strip applications, track-day builds, drag radial setups in the 1,000–1,500 whp range. 

The S2 is for builds where the engine configuration, RPM target, or power level demands every advantage the oiling system can offer — dedicated drag race builds, road course engines running sustained high RPM, and applications above 1,500 whp where oil system margin matters. If you're asking which one you need, talk to your engine builder. If your engine builder already knows which one they want, it's probably this one. If you're running a daily/street truck, this is overkill.
