    The nature of a vacuum pump is to remove air, blow-by gases, and other contaminants from the crankcase of an engine. The vacuum pump's 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 rings. The use of these pumps 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. Whether you have a normally aspirated small block or a nitrous equipped pro-mod, one of Moroso's vacuum pumps with all the needed accessories has you covered. Use Moroso replacement pump fittings only. Moroso Vacuum Pump FAQs.
