The Melling M295HV pump is a high-pressure, standard-volume pump that offers improved resistance against cavitation at higher RPMs. The cast aluminum housing is CNC-machined and hard coat anodized. The cast iron cover is CNC-machined and phosphate coated. The relief valve features a screw-in valve plug. The factory LS oil pump suffers from cavitation above 6,200 RPM, which results in a drop in oil flow of nearly 1 GPM by 7,000 RPM. This cavitation can also aerate the oil, which causes drops in oil pressure and can result in oil starvation. This is why we do not recommend shifting any higher than 6,200 RPM with a stock engine. Engines that run at RPMs above 6,200 should use an upgraded Melling pump to prevent these issues.
