Real-world Results: 2015 Ford F-150 3.5l Ecoboost Gains 60+ Hp with E85 Flexfuel Conversion

The 2015 Ford F-150 equipped with the 3.5L EcoBoost engine has gained significant attention for its performance and efficiency. One of the most intriguing modifications available for this truck is the conversion to E85 FlexFuel, which allows the engine to run on a blend of gasoline and ethanol. This article explores the real-world results of this conversion, highlighting the power gains and benefits associated with using E85 fuel.

Understanding the EcoBoost Engine

The EcoBoost engine family, developed by Ford, combines turbocharging and direct fuel injection to deliver impressive power while maintaining fuel efficiency. The 3.5L EcoBoost engine in the 2015 F-150 produces 365 horsepower and 420 lb-ft of torque on standard gasoline. However, the potential for increased performance with E85 is noteworthy.

What is E85 FlexFuel?

E85 is a fuel blend that contains up to 85% ethanol and 15% gasoline. This high ethanol content allows for higher octane ratings, which can lead to increased horsepower and torque. The conversion to E85 FlexFuel involves modifications to the fuel system and engine tuning to optimize performance and efficiency.

Performance Gains from E85 Conversion

One of the most compelling reasons to convert to E85 is the significant increase in horsepower. Many owners have reported gains of over 60 horsepower after making the switch. This section breaks down the factors contributing to these performance improvements.

  • Higher Octane Rating: E85 has a higher octane rating than regular gasoline, allowing for more aggressive tuning and increased boost pressure.
  • Improved Fuel Atomization: The properties of ethanol help in better fuel atomization, leading to more efficient combustion.
  • Cooling Effect: Ethanol has a cooling effect on the intake charge, which can enhance performance by preventing knock.
