Oil Pumps
Original Equipment (OE) oil pumps are designed for specific oil volume and pressure output. The prescribed volume/pressure delivery is based on the engine's bearing clearances and intended use, and for an unmodified vehicle driven at normal speeds, the engine will have all the lubrication it requires. However, performance and racing engines usually have larger clearances and are driven at much higher RPMs, and so have very different oiling needs.
Traditionally, racing engines have been built with looser bearing clearances to allow for the crankshaft flex that can occur when a high-powered engine is pushed to the limit. If clearances were tight, this flex could result in metal-to-metal contact and premature wear. However, to accommodate the greater bearing clearance a high volume oil pump is required. Regardless of your engine's oil pressure demands, we have the pump to meet your needs.
We offer both cast iron and aluminum wet sump oil pumps with various volume and pressure ratings, so you can get the pump that's right for your application. In addition to increased volume/pressure, many pumps feature strengthening in key areas to withstand the increased stress, and modifications to prevent pump cavitation. Many of our pumps come with the pickups pre-installed, but we also have a large selection of pickups for stock as well as performance oil pans. We also offer heavy-duty related components like stronger oil pump driveshafts with steel sleeves.
In addition to a complete line of performance wet sump oil pumps, we also offer performance dry sump pumps. Dry sump pumps are externally mounted and have two or more ""stages"" that scavenge the oil from a shallow oil pan and send it to a remote reservoir. One of the stages is the pressure stage that supplies oil under pressure to the engine. Dry sump systems are used in most forms of racing, and allow low chassis heights thanks to the shallow oil pan, no power loss from oil resistance, increased oil capacity, and improved ring seal from the crankcase vacuum developed by the oil pump.
While not an oil pump in the traditional sense, an accumulator does provide pressurized oil to the engine at critical times. An accumulator is an aluminum cylinder containing an air charge and engine oil separated by a hydraulic piston. The accumulator is filled with oil when the engine runs. During engine startup the accumulator pressurizes the engine with oil to prevent dry start damage. If oil pressure drops during vehicle operation, such as under hard acceleration, cornering or braking, the accumulator will also release oil until normal oil pressure resumes. We offer accumulators with a range of oil capacities.
