Complete your EVP DT-200 Turbo System with the Evolution Powersports Blow Off Valve (BOV) Kit. Specifically engineered for the Can-Am Defender HD11, this precision-machined billet aluminum BOV helps prevent compressor surge, improves throttle response, and protects your turbocharger during rapid throttle transitions. Unlike universal automotive blow off valves, the EVP BOV was designed exclusively for powersports turbocharged engines. Each valve is calibrated with the proper spring rate for the Defender HD11, providing reliable operation without boost leaks while delivering the unmistakable blow off valve sound enthusiasts love. Why Install a Blow Off Valve? When the throttle closes under boost, compressed air has nowhere to go, creating compressor surge that can reduce throttle response and place unnecessary stress on the turbocharger. The EVP Blow Off Valve safely vents excess boost pressure, helping improve turbo longevity and maintain consistent performance.
