In the world of automotive performance, few modifications can yield as significant results as upgrading the fuel system. My journey to achieving 400 wheel horsepower (WHP) in my EcoBoost Mustang began with the installation of the GPA E85 fuel system. This article details the real-world results of this modification and how it transformed my driving experience.
Understanding the EcoBoost Mustang
The Ford EcoBoost Mustang is known for its blend of performance and efficiency, thanks to its turbocharged engine. However, enthusiasts often seek to push these limits further. The stock fuel system can restrict performance, especially when tuning for higher power levels. This is where the GPA E85 fuel system comes into play.
What is the GPA E85 Fuel System?
The GPA E85 fuel system is designed to optimize fuel delivery for vehicles running on E85, a blend of 85% ethanol and 15% gasoline. Ethanol has a higher octane rating than regular gasoline, allowing for more aggressive tuning and increased horsepower. The system includes upgraded fuel pumps, injectors, and necessary hardware to support higher fuel flow rates.
Installation Process
Installing the GPA E85 fuel system in my EcoBoost Mustang was a straightforward process, though it required some mechanical knowledge. Here’s a brief overview of the steps involved:
- Remove the rear seats and access the fuel tank.
- Disconnect the stock fuel pump and remove it from the tank.
- Install the GPA fuel pump and connect it to the existing fuel lines.
- Replace stock injectors with the upgraded GPA injectors.
- Reassemble the fuel tank and reconnect all electrical connections.
Tuning for Performance
After the installation, the next crucial step was tuning the vehicle to take full advantage of the new fuel system. I opted for a professional tune to ensure optimal performance and reliability. The tuner adjusted the air-fuel ratio and ignition timing to accommodate the E85 fuel, maximizing power output while maintaining engine safety.
Real-World Results
With the GPA E85 fuel system installed and tuned, I was eager to see the results. The dyno session revealed impressive gains:
- Stock Power: Approximately 300 WHP
- Post-Installation Power: Approximately 400 WHP
- Torque Increase: Significant improvement in torque delivery
The increase in power was not just on paper; the car felt more responsive and exhilarating to drive. The throttle response improved significantly, and the car pulled harder throughout the entire RPM range.
Driving Experience
The driving experience of my EcoBoost Mustang after installing the GPA E85 fuel system was nothing short of phenomenal. The added power transformed the vehicle into a true performance machine. Here are some observations:
- Acceleration: The car launched with authority, providing an adrenaline-pumping experience.
- Throttle Response: Immediate and sharp, making driving more engaging.
- Sound: The exhaust note became more aggressive, enhancing the overall driving ambiance.
Fuel Economy Considerations
While E85 fuel provides performance benefits, it’s important to note that it can affect fuel economy. Ethanol has a lower energy content than gasoline, which may lead to slightly reduced fuel efficiency. However, the trade-off for performance was worth it for me, as the thrill of driving outweighed the decrease in miles per gallon.
Conclusion
The GPA E85 fuel system has been a game-changer for my EcoBoost Mustang, allowing me to achieve 400 WHP and significantly enhancing my driving experience. For anyone looking to maximize their EcoBoost’s performance, this upgrade is highly recommended. It’s a testament to how the right modifications can transform a vehicle into a high-performance powerhouse.
