Tuning your Turbosmart Kompact Shortie BOV can significantly enhance the performance of your Honda Civic Si. This guide will walk you through the steps necessary to achieve maximum power gains.

Understanding the Turbosmart Kompact Shortie BOV

The Turbosmart Kompact Shortie BOV is designed to improve turbo response by releasing excess pressure when the throttle is closed. This prevents compressor surge and helps maintain boost pressure, leading to better performance.

Tools and Materials Needed

  • Turbosmart Kompact Shortie BOV
  • Socket set
  • Wrench set
  • Tuning software (if applicable)
  • Vacuum gauge
  • Boost controller (optional)

Installation Steps

Removing the Stock BOV

Before installing the Turbosmart BOV, you need to remove the stock unit. Follow these steps:

  • Locate the stock BOV on your Honda Civic Si.
  • Disconnect the vacuum line from the stock BOV.
  • Remove the bolts securing the stock BOV.
  • Take out the stock BOV and clean the mounting surface.

Installing the Turbosmart Kompact Shortie BOV

Now, it’s time to install the new BOV. Follow these steps:

  • Position the Turbosmart BOV onto the mounting surface.
  • Secure it with the provided bolts.
  • Reconnect the vacuum line to the new BOV.
  • Ensure all connections are tight and secure.

Tuning the BOV for Maximum Performance

After installation, tuning the BOV is crucial for optimal performance. Here are the steps to tune your BOV:

Adjusting the Spring Pressure

The spring pressure in the BOV can be adjusted to suit your specific boost levels. Follow these steps:

  • Locate the adjustment screw on the top of the BOV.
  • Use a screwdriver to turn the screw clockwise to increase pressure or counterclockwise to decrease pressure.
  • Start with the factory setting and make small adjustments.
  • Test drive the vehicle to assess performance changes.

Using a Vacuum Gauge

A vacuum gauge can help you fine-tune the BOV settings more accurately. Here’s how to use it:

  • Connect the vacuum gauge to the vacuum line of the BOV.
  • Start the engine and let it idle.
  • Observe the vacuum reading while revving the engine.
  • Adjust the BOV spring pressure based on the readings for optimal performance.

Testing and Fine-Tuning

Once you have made the initial adjustments, it’s essential to test the setup to ensure everything is functioning correctly.

Road Testing

Take your Honda Civic Si for a test drive to evaluate the performance of the BOV. Pay attention to:

  • Turbo response during acceleration.
  • Sound of the BOV during shifts.
  • Any signs of compressor surge.

Making Further Adjustments

Based on your road test, you may need to return to the adjustment screw and make further tweaks. Repeat the testing process until you achieve the desired performance.

Conclusion

Tuning your Turbosmart Kompact Shortie BOV is a straightforward process that can lead to significant power gains in your Honda Civic Si. By following the steps outlined in this guide, you can ensure your vehicle performs at its best.
