Dump Valve BOV5 Plumb Back Universal 32mm

Turbosmart BOV5 Plumb Back Dump Valve – Universal 32 mm

Turbosmart is a leading Australian manufacturer specializing in turbo engine tuning, active since 1997 under the motto "Engineered to Win." A long-standing specialist in dump valves (blow-off valves), the brand designs, machines, and tests its products in-house to guarantee reliability, sealing, and performance.

The BOV5 (Type 5) range is Turbosmart's intermediate tier, for serious road performance and track use, supporting power levels of roughly 500 to 700 hp depending on configuration. It covers several valve families from 25 to 38 mm, in universal versions or ones specific to iconic vehicles: Vee Port Pro (compact VTA, optimized flow), Dual Port (dual outlet, versatile for road/track), Plumb Back (full recirculation, MAF-compatible), Supersonic (signature distinctive sound), and Smart Port (the most refined sequential-timing Dual Port). All benefit from Turbosmart's Boost-Balance technology, which seals the valve more tightly as boost pressure rises. This is the go-to range for going beyond a simple direct replacement, with a genuine choice of vent styles and sizes.

Turbosmart BOV5 fully recirculating (Plumb Back) dump valve, universal 32 mm mounting. Designed to return all bypassed air to the intake: quiet operation, MAF-compatible, ideal for preserving the original engine management.

Billet aluminum body, 38 mm piston with positive sealing, Boost-Balance technology, quick-lock V-band clamp, and tool-free cap-adjustable spring preload. Supplied with a weld-on adapter for custom installation.
