The 2016 Hyundai Veloster Turbo is a popular choice among car enthusiasts, particularly for those interested in performance upgrades. One of the key modifications many owners consider is the installation of a blow off valve (BOV). This guide will provide an overview of what a BOV is, its benefits, installation options, and maintenance considerations.

What is a Blow Off Valve?

A blow off valve is a device that releases pressure from the intake system when the throttle is closed suddenly. This helps prevent compressor surge, which can damage the turbocharger. The BOV opens to vent excess pressure, allowing the turbo to spool more efficiently and prolonging its lifespan.

Benefits of Installing a BOV

  • Improved Performance: A BOV can enhance throttle response and improve turbo efficiency by reducing back pressure.

  • Sound Enhancement: Many enthusiasts enjoy the distinctive "whoosh" sound produced when the BOV vents excess pressure.

  • Reduced Turbo Lag: By maintaining boost pressure when shifting or decelerating, a BOV can help reduce turbo lag.

Types of Blow Off Valves

When selecting a BOV for the 2016 Veloster Turbo, you have several options:

  • Recirculating Valves (BPV): These valves redirect vented air back into the intake system. They are quieter and often preferred for daily driving.

  • Atmospheric Valves (BOV): These vent air to the atmosphere, creating a loud sound. They are popular among performance enthusiasts but may cause issues with engine management systems if not tuned properly.

Installation Considerations

Installing a BOV can be straightforward but requires some mechanical knowledge. Here are general steps to follow:

1. Preparation: Ensure the engine is cool and gather necessary tools.

2. Remove Front Bumper: Access to the factory BOV typically requires removing the front bumper.

3. Disconnect Factory BOV: Remove vacuum hoses and bolts securing the OEM valve.

4. Install New BOV: Follow manufacturer instructions for your chosen BOV model, ensuring all connections are secure.

5. Test for Leaks: After installation, start the engine and check for any air leaks.

Maintenance Tips

Regular maintenance of your BOV will ensure optimal performance:

  • Cleaning: Depending on usage conditions, clean your BOV every 6 months to prevent buildup that could affect operation.

  • Inspection: Check hoses and connections regularly for wear or damage.

  • Adjustment: If you notice performance issues or changes in sound, adjustments may be needed based on your driving style and setup.

FAQs About Veloster Turbo Blow Off Valve

    • Do I need to tune my car after installing a BOV?
      It depends on whether you choose a recirculating or atmospheric valve. Atmospheric valves may require tuning to prevent stalling issues.

    • Can I install a BOV myself?
      Yes, if you have basic mechanical skills and tools. However, professional installation is recommended for those unfamiliar with car modifications.

    • What should I do if my engine stalls after installing a BOV?
      Check all connections for leaks and ensure that the correct type of valve is installed for your setup.

In summary, upgrading to a blow off valve on your 2016 Hyundai Veloster Turbo can enhance performance and provide an enjoyable driving experience. Choose wisely based on your preferences and ensure proper installation and maintenance for best results.
