by

The Subaru WRX is known for its impressive performance and tuning potential. One popular modification among enthusiasts is the installation of a boost controller, such as the Apexi AVC-R. This article explores how much power the Apexi AVC-R boost controller can add to your Subaru WRX.

Understanding Boost Controllers

Boost controllers are devices that help manage the amount of boost pressure produced by a turbocharger. By adjusting the boost levels, drivers can optimize engine performance, leading to increased power output. The Apexi AVC-R is a popular choice due to its advanced features and ease of use.

How the Apexi AVC-R Works

The Apexi AVC-R allows users to set and control boost levels through a digital interface. It features a built-in boost gauge, which provides real-time data on boost pressure. The AVC-R can also store multiple boost settings, making it versatile for different driving conditions.

Installation Process

Installing the Apexi AVC-R in a Subaru WRX requires some technical knowledge. The process generally involves:

  • Disconnecting the battery.
  • Mounting the AVC-R unit in a suitable location.
  • Connecting the vacuum lines to the turbocharger and wastegate.
  • Wiring the unit to the vehicle’s electrical system.
  • Calibrating the AVC-R settings for optimal performance.

Power Gains with the Apexi AVC-R

The power gains from installing an Apexi AVC-R boost controller can vary based on several factors, including the specific model of the WRX, existing modifications, and tuning. However, many users report significant increases in horsepower and torque after installation.

Typical Power Increases

On average, the addition of the Apexi AVC-R can lead to:

  • Increases of 20-30 horsepower at the wheels.
  • Torque gains of 15-25 lb-ft.

Factors Influencing Power Output

While the Apexi AVC-R can provide substantial power gains, several factors influence the final output:

  • Current engine modifications (exhaust, intake, etc.).
  • Tuning quality (professional vs. DIY).
  • Fuel quality and type used.
  • Turbocharger efficiency and size.

Benefits of Using the Apexi AVC-R

Beyond power gains, the Apexi AVC-R offers several other benefits:

  • Improved throttle response.
