Product Description

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.
