Blow off valves by Turbosmart are manufactured with a focus on performance and reliability.
Turbosmart blow off valves (also known as diverter valves, recirc valves) are made in Australia from tough and durable billet aluminium. Turbosmart offers a complete range of solutions from road car to race applications.
The Turbosmart Kompact range provides OEM replacement parts, including the SEMA Best New Performance Product, EM (Electro-Mechanical) Kompact range for valves that require ECU communication.
The BOV 5 range bridges the gap in the space between street and race where greater flow is needed in higher performance applications.
Across the Race Port, Power Port and Big Bubba series, Turbosmart engineers and builds high quality race parts designed to handle boost control in higher horsepower applications, giving you maximum efficiency and performance in your turbocharged application.
With bullet-proof, billet construction the Kompact range is a direct replacement for OEM parts. With a focus on quality materials, design & construction, the Kompact range gives vehicles the high performance edge in boost handling capacity, reliability & response, whilst being competitively priced.
The award-winning Kompact EM series Blow-Off Valves, are the world’s first truly plug and play Blow-Off Valves that retains complete OE control of the BOV’s operation.. Simply remove your OEM valve and replace. No adapters, hoses or extra assembly required.
Designed for high flow and performance, the Type 5 valves are well suited for both street and race vehicles requiring the handling of bigger boost control. The Type 5 line incorporates clever modular design, with precision machining and assembly
An amazingly small and light BOV for forced induction competition level engines, the Race Port has race proven results from street, strip and circuit. Featuring our unique collar design, twin 1/8”NPT pressure ports and internal flow structures, it is 50% lighter and 25% smaller than the competition, while flowing 330 CFM - making it the highest flowing BOV of it’s type on the market.
Designed for large capacity supercharged and turbocharged engines, including turbo-diesels, the Big Bubba is our largest piston style Blow-Off Valve. The Big Bubba range features precision engineering, bigger inlet and outlet ports, hard anodised and light weight aluminium pistons, along with a strong v-band mounting system.
The Power Port is Turbosmart’s largest and highest flowing Blow-Off Valve ever, resetting the flow benchmark set by our popular and highly regarded Race Port BOV. The Power Port’s massive 2.5in inlet, unprecedented valve lift, supersized ports and carefully designed CFD flow-paths mean it has more than enough breathing room for even the most powerful turbocharged drag racing engines, preventing damaging compressor surge and throttle plate damage at the end of the quarter mile, even at the most extreme boost levels.
The Turbosmart BOV controller is an electronic device which controls the pressure signal to the BOV. It works by detecting a negative voltage change in throttle position. It then energises a solenoid to vent all of the air out of the BOV cap, causing a pressure differential between the piston of the BOV and the cap which will vent pressure from the intake system.
