A high lift cam in a performance street vehicle can offer up great sound and excellent performance. But if your car or truck has power brakes, a minimum of 16 inches of vacuum is critical to proper brake booster operation, something not always present if your camshaft features enhanced overlap. The COMP Cams Electric Vacuum Pump ensures that your vacuum stays between 18 and 22 inches so you never have to worry whether your brakes will be there when you need them. Triggered by a vacuum switch included in the kit, the COMP Cams Electric Vacuum Pump requires a 12V negative ground system and only operates when vacuum drops below 18 inches of vacuum and then turns off over 22 inches of vacuum. The kit includes all of the parts necessary to install the unit along with wiring, hoses and brackets. The system utilizes a highly efficient electric pump, relay switch and distributor with vacuum switch, which should be mounted close together for the most effective performance.
