Serious Boost Requires a Blow Off Valve That Can Keep Up

When you're moving serious amounts of air through a turbocharged engine, a small conventional blow off valve can become a restriction.

The Turbosmart RacePort was designed for high-performance and competition-level turbo systems that demand massive airflow, fast response, and reliable boost control.

Despite its compact size, the RacePort flows over 330 CFM through its 2-inch / 50mm inlet, delivering exceptional airflow in a lightweight package.

330+ CFM of Airflow

When you lift off the throttle under boost, that pressurized air needs somewhere to go—fast.

The RacePort's internal flow path has been CFD-designed and optimized to move a huge volume of air quickly, helping relieve compressor surge and protect your turbocharger.

With more than 330 CFM of flow capability, the RacePort is built for applications where conventional BOVs may struggle to evacuate enough air.

Smaller. Lighter. More Flow.

Turbosmart designed the RacePort to provide serious airflow without adding unnecessary size or weight to your turbo system.

Its compact design is approximately:

• 50% lighter than competing designs
• 25% smaller
• Capable of flowing 330+ CFM

That makes it especially useful in crowded engine bays where space is limited but airflow requirements are high.

Built for High-Horsepower Turbo Applications

The RacePort is an excellent choice for:

• High-horsepower turbo builds
• Drag racing
• Roll racing
• Time attack
• Road racing
• High-boost street cars
• Large-frame turbochargers
• High-flow intercooler systems
• Custom turbo kits

Whether you're building a 600 HP street car or a four-digit horsepower race setup, the RacePort gives your turbo system the airflow capacity needed when the throttle closes.

Billet Aluminum Construction

The RacePort features 6000-Series billet aluminum construction, providing a strong yet lightweight housing designed to handle demanding performance environments.

Internally, Turbosmart uses a MILSPEC hard-anodized valve guide and stem along with a high-temperature proprietary Silicon Nomex diaphragm for durability under extreme conditions.

Quick-Release V-Band Installation

The 50mm / 2-inch inlet uses an aluminum V-band mounting system, providing a secure connection while making removal and servicing straightforward.

Turbosmart's locking collar design also allows for a compact, clean installation.

Protect Your Turbo Between Shifts

A blow off valve isn't just about making noise.

When the throttle closes while the turbo is still producing boost, pressure can rapidly build between the compressor and throttle body. Properly venting that pressure helps reduce compressor surge and allows your turbo system to respond properly during shifts and throttle transitions.

For high-flow, high-boost applications, you need a BOV capable of moving enough air to keep up.

The Turbosmart RacePort 50mm BOV combines huge airflow capacity, compact packaging, lightweight construction, and proven motorsport-focused engineering into one serious blow off valve.

Big turbo. Big boost. Give that air somewhere to go.
