Used with oil pump vacuum systems.
By creating a negative pressure condition in the crank case, improved ring seal and reduced windage losses result.
Improving engine efficiency and increasing horsepower in nitrous and high boost turbo applications.
A second benefit to a vacuum system is reducing the amount of methanol dilution that occurs to the oil when running an engine on methanol.
Helps create vacuum in crankcase.
Improves piston ring seal
Prevents blowing oil seals.
Adjustable cauum settings
* increases horsepower.
