Granatelli 64mm Anaconda Blow off Valve

Granatelli Motorsports Anaconda 64mm Blow Off Valve – Part #540199

The Granatelli Motorsports Anaconda 64mm Blow Off Valve is engineered from over 40 years of racing development, designed to deliver maximum airflow performance and advanced boost control for turbocharged and centrifugal supercharged engines. Built around a massive 64mm valve body, it provides the highest measured flow capacity of any valve in its class.

Manufactured from billet 6061 aluminum and finished in a durable black anodized coating, this valve is built for extreme thermal and mechanical stress. Its diaphragm-over-piston actuation system ensures fast, consistent response under both vacuum and boost conditions.

The Anaconda features dual 1/8" NPT top ports and a dedicated lower reference port, allowing for multiple boost reference and plumbing configurations. This enables the valve to function not only as a traditional blow off valve, but also as a cold-side boost control device in specialized racing applications.

When used as a BOV, it prevents compressor surge, protects turbo and supercharger components, and improves throttle response during shifts and deceleration. When configured for boost management, it allows controlled pressure release to shape boost curves and limit maximum boost output in centrifugal supercharger systems.

The internal spring adjustment system provides fine-tuned control over opening pressure, making it adaptable to a wide range of performance setups. Designed for serious racing environments, the Anaconda delivers precision, durability, and unmatched airflow performance.
