Granatelli Motor Sports 64mm Anaconda Blow Off Valve

The Culmination of 40+ Years of Forced Induction Experience

They all claim to have “decades of experience” in the boosted world—but J.R. Granatelli defines it. As the Lead Engineer and President of Paxton Supercharger, he helped shape the industry long before boost became mainstream. The Granatelli family holds over 300 land speed records, all centered around forced-induction innovation.

At just 16 years old, J.R.’s daily-driven Chevrolet Camaro reached an incredible 261 MPH at Bonneville, holding the record for eight additional years. The Granatelli Anaconda 64mm Blow Off Valve represents the peak of his 40+ years of racing and engineering expertise—a no-compromise, high-flow BOV engineered for the most demanding turbo and supercharged applications.
