Boundary

Building an engine for more power and higher revs? Then the oil pump is a part you should not overlook. Boundary, also known as Boundary Racing Pumps, makes oil pumps and oil pump parts for performance engines. Here you’ll find complete oil pumps and reinforced pump gears designed to ensure stable oil pressure when the engine works hard.

Oil pump specialists

Boundary is an American brand that specialises in one thing: oil pumps for engines pushed beyond what they were originally built for. The brand is especially well known in the Ford community, including for Coyote and Modular engines, where the stock pump gears can be a weak point at high revs and increased power. By focusing narrowly on oil pumps, Boundary has built a range that many engine builders use when an engine needs to be built stronger.

Boundary’s key products

Complete oil pumps are the core of the range. They are built with stronger gears and tight tolerances so the pump can deliver stable oil pressure under heavy load. For many engines there are also reinforced billet steel pump gears as an upgrade for the stock pump. The range also includes pumps and parts for several other popular performance engines. Fitting an oil pump involves work inside the engine, so it is best left to an experienced mechanic. See each product for engine fitment.

Frequently asked questions

Why upgrade the oil pump in a performance engine?

At higher revs and power, the oil pump is under greater stress. A stronger pump or reinforced pump gears reduce the risk of failure and help maintain stable oil pressure.

Should I choose a complete pump or just new gears?

It depends on the condition of the engine and your project. For a new or rebuilt engine many choose a complete pump, while reinforced gears can be a solution if the stock pump is otherwise in good condition.
