Product Details
The Turbosmart GenV RacePort 50mm Blow-Off Valve – Red, Female Flange (TS-0204-1144) is a high-performance atmospheric blow-off valve engineered for turbocharged applications requiring exceptional airflow capacity, fast response, and reliable boost pressure relief. Featuring a 50mm inlet, red anodized billet aluminum construction, and female-style mounting flange, the GenV RacePort delivers race-proven performance in a compact, lightweight design.
Designed for high-horsepower street, track, and competition turbocharger systems, the GenV RacePort utilizes Turbosmart's advanced fifth-generation valve technology to provide rapid pressure release when the throttle closes. This helps reduce compressor surge, protects turbocharger components, and improves boost recovery between gear changes.
The TS-0204-1144 is specifically designed with a female flange mounting configuration compatible with appropriate competitor-style mounting systems, including compatible TiAL Q-style flanges. This makes it an excellent upgrade for vehicles already equipped with a suitable blow-off valve mounting flange.
Unlike the standard RacePort versions that include a weld-on mounting flange, this female-flange variant is intended to utilize an existing compatible mounting arrangement. A weld-on flange is not included.
Manufactured from 6000-series billet aluminum, the RacePort features a MIL-SPEC hard-anodized valve guide and stem, a high-temperature silicone Nomex diaphragm, and Turbosmart's proprietary boost-balance technology. These components work together to provide consistent sealing, smooth valve operation, and dependable performance under demanding boost conditions.
The RacePort's optimized 2.0-inch inlet is capable of flowing over 330 CFM, providing substantial pressure relief capacity for high-output turbocharger applications.
Its compact construction is approximately 50% lighter and 25% smaller than competing blow-off valves, according to Turbosmart, making it particularly useful in performance engine bays where space and weight are important considerations.
The TS-0204-1144 comes equipped with a blue spring rated for approximately -18 to -14 inHg of manifold vacuum, making it suitable for many conventional turbocharged engine applications. Additional spring options are available separately to accommodate different engine vacuum characteristics.
Whether upgrading a turbocharged Honda K20/K24, replacing an existing TiAL-style blow-off valve, or assembling a custom high-horsepower turbo system, the Turbosmart GenV RacePort TS-0204-1144 provides excellent pressure relief performance, reliable sealing, and the distinctive sound of an atmospheric blow-off valve.

High-Flow 50mm RacePort Design
The GenV RacePort features a 50mm inlet designed to rapidly discharge compressed intake air when the throttle closes.
During turbocharger operation, the compressor supplies pressurized air through the intercooler and charge piping.
When the throttle closes, the sudden restriction can create a pressure wave within the intake system.
The RacePort opens to release this excess pressure, helping reduce compressor surge and associated stress on the turbocharger.
With a flow capacity exceeding 330 CFM, the RacePort is designed to handle substantial airflow in high-performance turbocharger applications.
Female Flange Mounting Configuration
The TS-0204-1144 features a female-style mounting arrangement designed for compatible competitor blow-off valve flanges.
This configuration is particularly useful when upgrading an existing TiAL Q-style blow-off valve installation.
The design allows the Turbosmart RacePort to be installed using an appropriate existing mounting flange without requiring a completely new charge pipe.
Important: The TS-0204-1144 does not include a weld-on mounting flange. Verify the existing flange dimensions and mounting compatibility before ordering.
Red Anodized Billet Aluminum Construction
The GenV RacePort is manufactured from 6000-series billet aluminum.
This construction provides excellent strength while minimizing overall weight.
The red anodized finish offers corrosion resistance and complements performance engine bay components.
Over 330 CFM Flow Capacity
Turbosmart designed the RacePort with optimized internal flow passages capable of flowing more than 330 CFM.
This allows the valve to release substantial amounts of compressed intake air during throttle closure.
Adequate blow-off valve flow capacity is particularly important in high-output turbocharger applications.
Blue Spring – -18 to -14 inHg
The TS-0204-1144 comes equipped with a blue spring rated for approximately -18 to -14 inHg of manifold vacuum.
This spring is suitable for many conventional turbocharged engine applications.
Different engines produce different manifold vacuum levels depending on camshaft specifications, engine displacement, throttle configuration, and operating conditions.
Turbosmart offers alternative spring options for applications requiring different valve opening characteristics.
Spring selection should be based on actual engine vacuum measurements and the manufacturer's recommendations.
Boost-Balance Technology
The GenV RacePort incorporates Turbosmart's boost-balance technology.
This design helps maintain consistent valve operation across varying boost pressure conditions.
Proper valve balance allows the RacePort to remain securely closed during boost while responding quickly when pressure relief is required.
Positive-Sealing Valve Seat
The RacePort features a positive-sealing valve seat designed to minimize unwanted boost pressure leakage.
Maintaining a reliable seal is essential for consistent turbocharger performance.
A leaking blow-off valve can contribute to reduced boost pressure, inconsistent engine performance, and increased turbocharger workload.
High-Temperature Silicone Nomex Diaphragm
The GenV RacePort incorporates a high-temperature silicone Nomex diaphragm.
This component is designed to withstand the pressure changes and operating temperatures commonly encountered in turbocharged applications.
The diaphragm helps provide responsive valve movement and consistent operation.
MIL-SPEC Hard-Anodized Valve Guide and Stem
The RacePort features a MIL-SPEC hard-anodized valve guide and stem.
These components provide excellent wear resistance and support smooth valve movement.
Consistent movement helps ensure reliable pressure relief during repeated throttle transitions.
Quick-Release V-Band Collar
The GenV RacePort utilizes Turbosmart's quick-release aluminum V-band collar.
This mounting system allows convenient valve installation and removal.
The design is particularly useful when servicing the valve or changing spring configurations.
Dual 1/8-Inch NPT Reference Ports
The RacePort incorporates two 1/8-inch NPT pressure reference ports.
These ports provide flexibility when routing the manifold vacuum reference hose.
The installer can select the port that offers the most convenient hose routing.
Unused ports must be properly sealed.
Optional Valve Position Sensor
The GenV RacePort platform supports an optional valve position sensor upgrade.
This feature allows compatible engine management systems to monitor blow-off valve operation.
Position monitoring may be useful for advanced tuning, diagnostics, and motorsport applications.
The position sensor is not included with TS-0204-1144.
Atmospheric Blow-Off Valve Sound
The TS-0204-1144 is designed to discharge excess boost pressure directly into the atmosphere.
This produces the distinctive blow-off valve sound associated with high-performance turbocharger systems.
Sound characteristics vary depending on turbocharger size, boost pressure, charge piping, and engine operating conditions.
GenV RacePort Female Flange vs. Standard RacePort
