The Melling M390HV Engine Oil Pump is a high-volume oil pump designed to increase engine oil flow, particularly in performance applications or engines that require additional oiling capabilities. While the exact oil pressure generated by the Melling M390HV pump can vary depending on the specific engine application, engine condition, and oil viscosity, here are some general expectations:
General Pressure Information for Melling M390HV Oil Pump:-
Increased Oil Pressure:
- The M390HV is a high-volume oil pump which is designed to flow more oil than a standard oil pump. Typically, this results in a slight increase in oil pressure compared to a standard volume pump.
- The increased flow can also provide better lubrication to engine components, particularly beneficial in high-performance or modified engines.
-
Pressure Range:
- The oil pressure generated by the pump can typically range from 40 to 70 psi (pounds per square inch), depending on the engine's operating conditions. At idle, pressure might be on the lower end of this range, while at higher RPMs, pressure could reach the upper end.
- Exact oil pressure can vary depending on factors such as engine type, engine wear, oil viscosity, oil filter used, and operating temperature.
-
Impact of Engine Modifications:
- In engines that have been modified for higher performance, including those with increased bearing clearances or additional oiling needs (such as aftermarket oil coolers or turbochargers), the M390HV pump can help maintain adequate oil pressure and flow to critical components.
-
Oil Pressure Specification:
- For a more precise specification, refer to your vehicle's service manual or consult Melling's technical support. They can provide guidelines for typical oil pressure ranges for specific engine applications using the M390HV pump.
- Oil Viscosity: Heavier (thicker) oils can lead to higher pressures, while lighter (thinner) oils may result in lower pressures. Always use the oil grade recommended for your specific engine and conditions.
- Engine Operating Temperature: Oil pressure generally decreases as the engine reaches its operating temperature. Cold oil is thicker and typically produces higher pressures when the engine first starts.
- Oil Pump Relief Valve: The M390HV pump includes a relief valve that helps regulate maximum oil pressure. If the relief valve is stuck or malfunctioning, it could affect the overall oil pressure.
To ensure you achieve the desired oil pressure and performance from the Melling M390HV oil pump, it is important to monitor the oil pressure with a reliable gauge, especially after installation, and make any necessary adjustments to engine components or oil type to achieve optimal performance.
