Moroso 22840 Billet Aluminum Racing Vacuum Pump

The Moroso 22840 is a high-performance racing vacuum pump engineered to maximize engine power and reliability. Manufactured from billet aluminum with precision-machined components including shaft, rotor, and bearings, this pump is built to withstand the extreme demands of competitive racing environments.

Performance Benefits:

• Produces high crankcase vacuum to increase horsepower by improving piston ring seal
• Prevents blowby and reduces risk of detonation
• Enables use of lower-tension piston rings for reduced friction and increased power
• Delivers consistent, reliable performance superior to header-mounted evacuation systems

Construction Features:

• Precision-machined billet aluminum housing for strength and heat dissipation
• High-quality bearings and rotor assembly designed for racing durability
• Positive displacement design ensures consistent vacuum levels

This vacuum pump provides a significant performance advantage over passive evacuation systems by actively removing crankcase pressure, allowing your engine to produce more power while maintaining optimal ring seal and reducing oil consumption.
