The nature of a vacuum pump is to remove, air, blow-by gasses and other contaminants from the crankcase of an
engine. The vacuum pumps ability to remove the air in the crankcase results in overall engine vacuum. Vacuum
will increase horsepower by allowing the use of low-tension compression and oil control rings. In which the use of
reduces frictional horsepower losses, blow-by, intake charge contamination and aids in detonation prevention.
Moroso’s “purpose built” racing pumps offer all these advantages and more.
• Versatile Billet aluminum design, well suited for wet or dry-sump applications
• Engineered vane material for improved efficiency and wear
• Completely rebuildable in 15 minutes
