Moroso Vacuum Pumps

3.8 out of 5 stars 5 Customer Reviews

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.
