COMP Cams Electric Vacuum Pump Kit

COMP Cams is well-known for making performance camshafts and valvetrain components that help engines breathe better and make more power. If you've installed a high-lift camshaft in your street performance vehicle, you know it can give you that aggressive idle and strong powerband you're after. However, these cams often have more valve overlap, which can reduce the engine's natural vacuum. For vehicles with power brakes, having at least 16 inches of vacuum is critical for them to work correctly, and a cam with increased overlap might not provide enough on its own.

That's where the COMP Cams Electric Vacuum Pump Kit comes in. This well-built kit ensures your power brakes always have the vacuum they need, keeping it consistently between 18 and 22 inches of mercury. It's designed to activate only when your engine's vacuum drops below 18 inches and shuts off once it reaches over 22 inches, so it only runs when necessary. The system uses an efficient electric pump, a relay switch, and a vacuum switch, all of which should be mounted together for optimal performance. This kit requires a 12-volt negative ground electrical system.

Everything you need for installation is included in the kit: the pump, wiring, hoses, and mounting brackets. This means you can get your power brakes functioning reliably again, even with a more aggressive camshaft, without compromising your ability to stop safely. It’s a smart way to ensure your performance build is also safe and street-friendly.
