As your engine gets hot, the aluminium housing expands faster than the steel gears inside, increasing internal clearances and causing oil pressure to drop—exactly when you need it most. Additionally, under high RPM harmonics, alloy housings can flex, leading to cavitation and inconsistent flow.\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cstrong\u003e💡 DID YOU KNOW?\u003c\/strong\u003e\n\u003cp\u003e\u003cstrong\u003eWe thoroughly test run every single pump across temperature and RPM.\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eManufacturing a steel pump is just the start. Our technicians manually port and smooth the oil galleries on every unit to remove casting flash and optimize flow dynamics. This attention to detail ensures maximum volumetric efficiency and reduces cavitation at high RPM. Our oil pump dyno lets us test every unit across temperature and RPM range before we send it out.
