A high-lift cam in a performance street vehicle can offer up great sound and excellent performance. COMP Cams electric vacuum pump kits ensure that your vacuum stays between 18 and 22 Hg so you never have to worry whether your brakes will be there when you need them. If your car or truck has power brakes, a minimum of 16 in. of vacuum is critical to proper brake booster operation, which is something that's not always present if your camshaft features enhanced overlap. These kits are triggered by a vacuum switch that's included. They require a 12 V negative-ground system and only operate when vacuum drops below 18 Hg, and then turn off over 22 Hg. They include all of the parts necessary to install the units, along with wiring, hoses, and brackets. The kits utilize a highly efficient electric pump, relay switch, and distributor with a vacuum switch, which should be mounted close together for the most effective performance.
