By producing high crankcase vacuum, horsepower is increased by improving ring seal and preventing blow-by, intake charge contamination and detonation. The Vacuum Pump allows racers to run low-tension piston rings for less friction and is more consistent and effective than header mounted evacuation systems. The Vacuum Pump features billet aluminum housing, sealed roller bearings, 1-piece lightweight carrier/shaft design, carbon fiber vanes,12- AN fittings and integral mounting lugs to fit most engine applications. The panel mounted remote breather/oil separator can be used with dry or wet sump tanks or rear axle housings. Features a filtered breather from K&N Filter, drain valve and a #12 fitting. The complete Aerospace Components kit includes the Vacuum Pump, Bracket and Pulley, Mandrel Drive System, Breather Tank, Relief Valve, 6 Stainless Steel Flex Hose, One -12 90 Fittings, Three -12 Straight Fittings, and Valve Cover Bung.
