Moroso Vacuum Pumps
Built for racers and engine builders who craved the performance, Moroso racing vacuum pumps are manufactured from billet aluminum and feature a precision-machined shaft, rotor, and bearings that will withstand the rigors of racing. They work by producing high crankcase vacuum, which increases power by improving ring seal, preventing blowby, and detonation. Allowing the use of lower-tension piston rings for less friction. These positive pumps are much more consistent and effective than header-mounted evacuation systems.

Moroso Engine Oil Accumulators
Moroso engine oil accumulators just might save your engine from damage, by giving you extra oil in reserve. Plumbed into the pressurized side of your oiling system, they use compressed air to force its oil reserve into your engine when the oil pressure drops below normal. When the pressure returns to normal, that reserve oil is forced back into the accumulators, and is ready for the next emergency.

Moroso Tri-Lobe Dry Sump Oil Pumps
Moroso aluminum Tri-Lobe dry sump oil pumps have been developed with their decades of oiling system expertise to provide you with a lighter, better performing design that will save weight and make more crankcase vacuum. They feature Tri-lobe aluminum scavenge sections with individual timing gears to ensure proper clearance at the highest rpm. The pumps use a spur gear pressure section based on Moroso's highly successful billet wet sump pump design, and variable spring rates optimize your oil pressure for smooth, reliable oil pressure readings. Moroso Tri-Lobe dry sump oil pumps have multiple -12, or -16 AN scavenge outlet options, weigh about half as much as gerotor pumps, and take up to 40 percent less power to drive.

Moroso Spur Gear Oil Pump Springs
Moroso offers replacement bypass relief springs for various spur gear oil pumps, used to regulate oil pressure by controlling the flow of oil back into the pump's inlet. The 3-spring kits are designed for use with Nos. 22163, 22164, and other billet Moroso spur gear BBC oil pumps, as well as Tri-Lobe Series external/dry sump pumps. Kits contain a blue (50-60 psi), purple (60-70 psi), and brown (70-80 psi) spring to help tune the engine's oil pressure to a desired level. These springs are a critical component of an oil pump's pressure relief system. When oil pressure exceeds a certain threshold, the spring compresses, allowing excess oil to bypass the main circulation and return to the pump's suction side, which prevents excessive pressure and potential engine damage.

Moroso Dry Sump Oil Pumps
Moroso dry sump oil pumps are the safest, most dependable oiling systems available. They're popular in all forms of racing, especially where low chassis height is important for good handling. Horsepower gain is maximized because there is virtually no oil in the pan and no internal pump, allowing the windage tray or screen to run the full length of the pan. Other advantages of a dry sump system include a remotely mounted oil tank for increased capacity, the ability to easily add remote oil coolers, more consistent oil pressure, adjustable oil pressure, improved scavenging, and increased ring seal due to greater pan vacuum. Brackets are included.
