Closed Race Bypass Valve Steel Flange Black 3FASS-007B By ProCharger

Got boost? Good. Got a valve that can handle it without sounding like a toddler with a kazoo? Even better.

Introducing the Enclosed Race Valve with Mounting Hardware, built for setups cranking out anywhere from 701 to 1200 horsepower. That’s right—this isn’t your grandma’s blow-off valve (unless she’s running a twin-turbo drag car, in which case… respect).

This bad boy is designed to keep your high-horsepower build breathing easy while maintaining stealth mode when you’re just cruising around town, pretending to be civilized. Unlike open race valves that announce every lift of the throttle like a party horn, this enclosed version keeps things just a little more hush-hush—without sacrificing an ounce of performance.

Perfect for serious street builds and track monsters alike, this race valve delivers reliable boost control while playing nice with your engine bay. And yes, it comes with the mounting hardware, so no emergency trips to the hardware store while your car’s mid-surgery.

Whether you’re chasing numbers, hunting trophies, or just trying to keep your internals happy while making power in the quadruple digits, this valve’s got your back. Built tough, runs quiet(ish), and installs without requiring an engineering degree or six extra hands.

Bottom line? It works. It fits. It doesn’t whine (unless you want it to). And it helps you hold down all those horses like a champ.
