Maximize Power Gains with the Cobb Blow Off Valve on Subaru Brz (200 Hp)

by

The Subaru BRZ, known for its lightweight design and agile handling, is a favorite among car enthusiasts. With a stock power output of around 200 hp, many owners look for ways to enhance performance. One effective modification is the installation of a COBB Blow Off Valve (BOV). This article explores how the COBB BOV can maximize power gains in your Subaru BRZ.

Understanding Blow Off Valves

A Blow Off Valve is a crucial component in turbocharged vehicles. It releases excess pressure from the intake system when the throttle is closed, preventing compressor surge. This not only protects the turbocharger but also enhances throttle response and overall performance.

Benefits of the COBB Blow Off Valve

The COBB Blow Off Valve offers several advantages for Subaru BRZ owners:

  • Improved Throttle Response: The COBB BOV allows for quicker release of pressure, leading to better throttle response when accelerating.
  • Enhanced Turbo Performance: By reducing compressor surge, the BOV helps maintain turbo efficiency, resulting in more power.
  • Adjustability: The COBB BOV features adjustable spring tension, allowing users to customize the release pressure based on their driving style.
  • Sound: The distinctive sound of the BOV can enhance the driving experience for enthusiasts.

Installation Process

Installing the COBB Blow Off Valve on your Subaru BRZ is a straightforward process that can be completed with basic tools. Here’s a step-by-step guide:

  • Gather Tools: You’ll need a socket set, screwdrivers, and possibly pliers.
  • Remove the Stock Valve: Locate the stock BOV and carefully disconnect the vacuum line and any clamps.
  • Install the COBB BOV: Position the COBB BOV in place and secure it with the provided hardware.
  • Reconnect Vacuum Line: Ensure the vacuum line is properly connected to the new BOV.
  • Test the Installation: Start the engine and listen for any leaks. Ensure the BOV operates correctly when revving the engine.

Tuning Considerations

While the COBB Blow Off Valve can be installed without a tune, optimizing your Subaru BRZ’s performance often requires tuning. A proper tune can ensure that the engine management system is calibrated to work efficiently with the new BOV. Here are some tuning considerations:

  • ECU Tune: Consider a COBB Accessport or similar tuning solution to adjust fuel maps and boost levels.
  • Monitoring Performance: Use gauges to monitor boost pressure and air-fuel ratios to ensure optimal performance.
  • Adjusting the BOV: Fine-tune the BOV’s spring tension based on your tuning setup for best results.

Real-World Performance Gains

Many Subaru BRZ owners report noticeable performance improvements after installing the COBB Blow Off Valve. These gains can manifest in various ways:

  • Increased Boost Response: Drivers often experience quicker spool times and more immediate power delivery.
  • Smoother Power Band: The BOV helps maintain a consistent power band, making the car feel more responsive.
  • Better Overall Driving Experience: Enhanced throttle response and turbo performance can make driving more enjoyable.

Conclusion

The COBB Blow Off Valve is a valuable modification for any Subaru BRZ owner looking to maximize power gains. With its ability to improve throttle response, enhance turbo performance, and provide a distinctive sound, it’s a worthy investment. Coupled with proper tuning, the COBB BOV can transform your driving experience, making your BRZ even more thrilling to drive.
