Blow-offValves

 Turbosmart Blow-off Valves are manufactured with a focus on performance and reliability. Turbosmart Blow-off valves (also known as diverter valves, recirc valves, DV’s etc) are made in Australia. Built and machined from tough, durable billet aluminium. With a complete range of solutions. Turbosmart offers OE Replacement and heavy-duty upgrades through all performance and street applications, race and of course for motorsport use. 

The Kompact range from Turbosmart is a range of upgraded valves to suit road cars, for normal, high performance and tuned use. The Turbosmart Kompact blow-off valve range includes the Kompact EM (Electro-Mechanical) series which takes the best of a mechanical valves reliability and adds integration with factory control electronics and strategies. Furthermore, the Kompact range relies on Turbosmart’s proven positive seal piston. The boost-balance system for years of reliability and trouble-free motoring.

The BOV5 range, our 5th iteration of a true performance valve, shares the same boost-balance, positive seal piston technology as the Kompact Range. High flowing than the Kompact range for higher horsepower setups. With a huge list of bolt-on, model specific and Universal Applications. The BOV 5 range bridges the gap in the space between street and race where the greater flow is needed in higher performance applications. 

For high horsepower and no compromise. Turbosmart offers the Race Port, Power Port and Big Bubba Ranges. With solutions based on both positive seal piston and diaphragm style valves. Most of all there are solutions for every application!

Race Port

ULTRA-HIGH PERFORMANCE | STREET | RACE | SUPERCHARGED – Up to 2500HP (50mm Valve)

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 its type on the market.

Big Bubba

HIGH PERFORMANCE | STREET | RACE | SUPERCHARGED | DIESEL PERFORMANCE – Up to 1500HP (2″/50.4mm Piston)

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 lightweight aluminium pistons. Also comes with a strong v-band mounting system.

Power Port

ULTRA-HIGH PERFORMANCE | RACE | SUPERCHARGED – Over 3000HP (60mm Valve)

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. This prevents damage to compressor surge and throttle plate damage at the end of the quarter-mile. Even at the most extreme boost levels.

BOV Controller

HIGH PERFORMANCE | STREET | RACE | DIESEL PERFORMANCE | SUPERCHARGED 

The Turbosmart BOV controller is an electronic device. It controls the pressure signal to the BOV. It works by detecting a negative voltage change in throttle position. Furthermore, it energises a solenoid to vent all of the air out of the BOV cap. This causes a pressure differential between the piston of the BOV and the cap. This will then vent pressure from the intake system.
