Granatelli 540199 64mm Anaconda Ultra High Flow Blow Off Valve Atmospheric

Vehicle Fitment

• Universal - compatible with most turbocharged boost applications; not vehicle-specific

Fitment Notes

• Atmospheric venting design - vents boost pressure to open air rather than recirculating it back into the intake tract; confirm this matches your intended setup and local sound/emissions preferences
• Larger 64mm body suited to higher-flow, higher-boost applications than the 50mm "Viper" (PN 540198)
• Sold individually
• Requires an aluminum weld flange installation (included) at the intake piping

Features

• Oversized 64mm valve for maximum flow on high-boost, high-horsepower setups
• Reduces compressor surge and helps protect the turbocharger
• Delivers a distinct, aggressive turbo blow-off sound
• Black anodized finish for corrosion resistance
• Swappable spring rates let you dial in response for street or strip use
• Track-tested, street-proven construction

Product Description

The Granatelli Anaconda steps up from the 50mm Viper to a 64mm body for builds pushing serious boost and airflow, where a smaller valve can become a bottleneck at full lift. It dumps pressure fast when the throttle closes, cutting compressor surge that can stress or damage the turbo over repeated hard shifts.

Included 6 psi and 15 psi springs let you tune response for daily street use or a dedicated strip setup without buying separate valves. The black anodized finish resists corrosion, and the kit ships with everything needed for a weld-in installation, including the flange and V-band hardware - a fit for high-horsepower turbo builds that have outgrown a smaller BOV.
