Granatelli 50mm Adjustable Turbo Blow-Off Valve with V-Band – 540200

50MM TURBO PRESSURE RELIEF

THAT “PSHHH” ISN’T THE IMPORTANT PART. GETTING THE PRESSURE OUT QUICKLY IS.

The Granatelli 540200 50mm Blow-Off Valve provides fast boost-pressure relief for street, street/strip and custom turbocharger systems.

Its billet construction, V-band mounting and interchangeable 6 PSI and 15 PSI springs make this an adjustable performance BOV for builders who need a strong, straightforward solution for controlling pressure when the throttle closes.

What This Blow-Off Valve Does

When the throttle blade closes under boost, compressed air can back up against the turbocharger compressor. The 540200 releases that trapped charge pressure quickly, helping reduce compressor surge and creating a cleaner transition between throttle events.
