Turbosmart Kompact Blow Off Valve – Dual Port

The Turbosmart Kompact range represents a substantial upgrade over factory-fitted blow-off valves (BOVs) or dump valves, designed as a direct replacement to enhance performance and reliability. This dual-port variant offers a balanced approach to venting excess boost pressure, providing audible turbocharger discharge whilst maintaining reasonable noise levels.

These valves are engineered for vehicles experiencing increased performance demands, capable of handling engines up to 400 horsepower. The Kompact series addresses the common issues found in original equipment (OE) plastic BOVs – namely weakening, leaking seals and eventual cracking due to age and stress. Installation is straightforward, requiring no adjustment post-fitting making it ideal for enthusiasts seeking a simple yet effective upgrade.

Key Features & Construction

• Billet Aluminium Body: Constructed from high-strength, lightweight billet aluminium for durability and heat dissipation.
• Precision Brass Piston: Utilises a precision-matched brass piston, eliminating the need for O-ring seals – a frequent point of failure in competing designs. This design choice contributes to improved responsiveness and extended service life.
• Direct Bolt-On Replacement: Engineered as an OE upgrade; designed to fit directly into existing systems without modification. Available in universal, turbo-specific, and vehicle-specific configurations (Shortie – flanged 2 or 3 bolt fitting).
• Dual-Port Design: This configuration provides a 50/50 split of vented charge air. Approximately half is recirculated back into the intake system, while the other half is released to atmosphere. This results in a noticeable ‘turbo whoosh’ sound at higher boost pressures, but remains relatively quiet during normal driving conditions.

Operational Characteristics

The Dual-Port design offers a compromise between fully venting to atmosphere (typically louder) and completely recirculating the charge air (quieter). This makes it suitable for drivers who desire an audible indication of turbocharger operation without attracting excessive attention or noise complaints.

Unlike some aftermarket valves, the Kompact series is designed to function effectively with minimal setup. The internal spring pressure is pre-configured to suit a wide range of boost pressures, ensuring optimal performance straight from the box. This eliminates the need for complex adjustments and fine-tuning.

Compatibility & Applications

The Kompact range is compatible with vehicles originally equipped with Bosch or Denso type valves, commonly found in VAG (Volkswagen Audi Group), Ford, Saab, and Porsche applications. Specific dimensions should be checked to ensure correct fitment for your vehicle.

For modern vehicles utilising electronically controlled BOVs/dump valves, Turbosmart offers the Kompact EM (Electro-Mechanical) variant. This version retains the Dual-Port or Plumb-Back charge air flow options but replaces the vacuum-operated activation with a faster and more accurate solenoid system that integrates seamlessly with the vehicle’s factory engine management system – providing a true plug-and-play solution.

Available Configurations

Turbosmart also provides Kompact BOV kits for specific applications. These kits may include multiple valves, hoses, and fittings to simplify the upgrade process. Please note that kit contents vary depending on the vehicle application.

• Universal: Suitable for a wide range of vehicles with adaptable hose connections.
• Turbo-Specific: Designed for particular turbocharger models, ensuring optimal fitment and performance.
• Vehicle-Specific: Tailored to specific vehicle makes and models, offering the most direct and seamless installation.

The Kompact series is a robust and reliable upgrade path for your vehicle’s boost control system. It provides improved flow characteristics, enhanced durability compared to plastic OE components, and simplified installation – all within a compact and aesthetically pleasing package.
