Best E85 Fuel System Mods for the Subaru Wrx: Achieving 30+ Hp Gains with Boostane and Buschur Racing Components

The Subaru WRX is a beloved vehicle among car enthusiasts, known for its performance and tuning potential. One of the most effective ways to enhance the WRX’s power output is by upgrading the fuel system, especially when utilizing E85 fuel. In this article, we will explore the best E85 fuel system modifications that can help you achieve over 30 horsepower gains using Boostane and Buschur Racing components.

Understanding E85 Fuel

E85 is a blend of 85% ethanol and 15% gasoline, which can provide significant performance benefits when used in vehicles designed for it. The higher octane rating of E85 allows for more aggressive tuning, leading to increased horsepower and torque. However, to take full advantage of E85, certain modifications to the fuel system are necessary.

Key Components for E85 Fuel System Mods

  • Fuel Pump: Upgrading to a high-flow fuel pump is essential to ensure adequate fuel delivery.
  • Fuel Injectors: Larger injectors are needed to accommodate the increased fuel flow required for E85.
  • Fuel Lines: Upgraded fuel lines may be necessary to handle the corrosive nature of ethanol.
  • Fuel Pressure Regulator: A higher capacity regulator helps maintain optimal fuel pressure.

Boostane: Enhancing E85 Performance

Boostane is a popular octane booster that can be mixed with E85 to further enhance its performance. By increasing the octane rating, Boostane allows for more aggressive tuning and can help prevent knock under high boost conditions. Here’s how to effectively use Boostane with your WRX:

  • Mixing Ratio: Start with a recommended mixing ratio of 1:1 with E85 for optimal results.
  • Tuning: Ensure your ECU is tuned to take advantage of the higher octane rating.
  • Testing: Regularly test your fuel mixture to maintain performance and prevent issues.

Buschur Racing Components

Buschur Racing offers a variety of components specifically designed for Subaru WRX models looking to maximize performance with E85. Here are some key components to consider:

  • Buschur Racing Fuel Pump: A high-performance pump designed to handle the demands of E85.
  • Buschur Racing Fuel Injectors: Larger injectors that provide the necessary flow rate for increased power.
  • Buschur Racing Fuel Rail: Upgraded fuel rails that improve fuel distribution and pressure.

Installation Tips

Proper installation of fuel system components is crucial for performance and reliability. Here are some tips to ensure a successful installation:

  • Follow Manufacturer Instructions: Always refer to the installation manuals provided by the manufacturers.
  • Use Quality Tools: Invest in the right tools to avoid damaging components during installation.
  • Check for Leaks: After installation, thoroughly check for fuel leaks before starting the engine.

Tuning Your Subaru WRX for E85

After upgrading your fuel system, tuning your WRX is essential to maximize the benefits of E85. A professional tune can help you achieve the best performance and reliability. Consider the following:

  • ECU Tuning: Work with a reputable tuner who has experience with E85 and Subaru vehicles.
  • Dyno Testing: Utilize a dynamometer to measure power gains and fine-tune your setup.
  • Monitor Engine Parameters: Keep an eye on air-fuel ratios, boost levels, and knock detection.

Conclusion

Upgrading your Subaru WRX’s fuel system to accommodate E85 can lead to impressive horsepower gains. By incorporating high-quality components from Buschur Racing and utilizing Boostane for enhanced performance, you can unlock the full potential of your vehicle. Remember to prioritize proper installation and tuning to enjoy a reliable and powerful driving experience.
