A blowoff valve (BOV), bypass valve or dump valve is a pressure release system present in most turbocharged engines. Its purpose is to prevent compressor surge, and reduce wear on the turbocharger and engine. Blowoff valves relieve the damaging effects of compressor "surge loading" by allowing the compressed air to vent to the atmosphere, making a distinct hissing sound, or recirculate into the intake upstream of the compressor inlet.

The Active Autowerke Blow Off Valve is a pull-type blow off valve suited for high horsepower applications. It is used extensively throughout the Active Autowerke product line both for turbocharging and supercharging. Constructed from an all aluminum cast body, with a large single stage, steel pull-type valve to handle the extreme pressure and airflow discharge volume that is associated with high boost / horsepower applications.

The BOV is engineered for up to 43psi of boost and can function precisely on BMWs producing more than the 500 horsepower range.

The QR50 BOV uses Stainless Steel hardware for a long lasting, corrosion-free appearance. The valve-seal utilizes a Viton O-ring that is clamped in place to prevent the possibility of sticking to the seat and pulling out. The valve stem and guide are Teflon-lubricated, hard anodize-coated for wear resistance. The Blow Off Valve also comes with TiAL machined aluminum banjo-type air fitting and bolt, with over sized 10mm hose barb for quick actuator response.

From Active Autowerke:

Our single BOV sports a huge venturi, designed to handle excess pressure build-up against the turbo compressor impeller blades. That pressure can cause the impeller to stop spinning (a.k.a. Compressor Surge),which can damage the compressor wheel and shaft. With our valve in place, the stock turbos are protected as the boost is raised – you can take HP to the stratosphere, enjoy the spoils of all that performance, and get that cool “whoosh” sound as your machine spits out excess inlet pressure.

All hardware & fittings have that quality factory look you demand, and are built to perform flawlessly under the most aggressive boost conditions.

Key Features:

High-efficiency single displacement BOV – takes place of two smaller plastic valves
Large opening can handle maximum boost, provide high flow
Proven and tested to handle 600+ HP
All aluminum venturi design with factory-style throttle clamp
CNC machined flange
Durable black powder-coated wrinkle finish
Illustrated instruction manual & installation guide for easy “Plug ‘n Play”
