The APR Blow Off Valve (BOV) has become a popular modification among car enthusiasts, especially those looking to enhance their vehicle’s performance. But does it really deliver the promised power gains, such as an increase of 20+ horsepower? In this article, we will explore the mechanics of the APR Blow Off Valve, its benefits, and whether it lives up to the hype.
Understanding the Blow Off Valve
A Blow Off Valve is a crucial component in turbocharged vehicles. It serves to release excess pressure from the intake system when the throttle is closed, preventing compressor surge and protecting the turbocharger. The APR Blow Off Valve is designed to improve performance by optimizing this process.
How It Works
The APR Blow Off Valve operates by venting excess boost pressure to the atmosphere or recirculating it back into the intake system. This action allows the turbocharger to spool more efficiently, providing quicker throttle response and improved performance.
Benefits of the APR Blow Off Valve
Installing the APR Blow Off Valve can offer several advantages for turbocharged vehicles. Here are some of the key benefits:
- Improved Throttle Response: By releasing pressure quickly, the BOV allows for faster turbo spooling.
- Enhanced Performance: A properly functioning BOV can lead to better overall performance and power delivery.
- Sound: Many enthusiasts appreciate the distinctive sound produced by venting excess pressure.
- Durability: The APR BOV is designed for longevity and can withstand high boost levels.
Does It Really Add 20+ Horsepower?
One of the most significant claims surrounding the APR Blow Off Valve is the potential for a power increase of 20+ horsepower. However, this number can vary based on several factors:
- Vehicle Type: Different vehicles respond uniquely to modifications, and not all will see the same gains.
- Existing Modifications: The overall performance of the vehicle can depend on other modifications already in place.
- Tuning: Proper tuning is essential to maximize the benefits of any performance modification.
Real-World Power Gains
In real-world testing, many drivers report varying levels of power increase after installing the APR Blow Off Valve. While some may experience gains close to or exceeding 20 horsepower, others may find the improvements to be more subtle. It’s essential to consider the entire setup of the vehicle when evaluating performance changes.
Installation Considerations
Installing the APR Blow Off Valve is generally straightforward, but there are several considerations to keep in mind:
- Compatibility: Ensure that the BOV is compatible with your vehicle’s make and model.
- Professional Installation: While some may choose to install it themselves, professional installation can ensure optimal performance.
- Post-Installation Tuning: After installation, a tune may be necessary to fully realize performance benefits.
Conclusion
The APR Blow Off Valve has the potential to enhance the performance of turbocharged vehicles significantly. While claims of 20+ horsepower gains may be ambitious for some setups, the benefits in throttle response and overall performance can be substantial. For those looking to improve their vehicle’s performance, the APR BOV is a worthy consideration, particularly when combined with proper tuning and additional modifications.
Ultimately, whether or not the APR Blow Off Valve adds 20+ horsepower will depend on the specific vehicle and its configuration. Enthusiasts should weigh the pros and cons and consider their goals when deciding on this modification.
