The FA20 engine, known for its efficiency and performance, has gained significant attention among automotive enthusiasts. One of the most effective modifications to boost its power output is the conversion to E85 fuel. This article explores the performance gains achievable with this conversion, detailing how it can add up to 40 horsepower.
Understanding E85 Fuel
E85 is a fuel blend consisting of 85% ethanol and 15% gasoline. This high ethanol content allows for a higher octane rating, which can lead to improved combustion efficiency and increased power output in performance engines like the FA20.
Benefits of E85
- Higher octane rating reduces the risk of knock.
- Improved combustion efficiency leads to better fuel economy.
- Increased power output due to more aggressive tuning options.
- Lower emissions compared to traditional gasoline.
Performance Gains with E85 Conversion
Converting the FA20 engine to run on E85 can yield impressive performance gains. With proper tuning and supporting modifications, drivers can expect an increase of up to 40 horsepower. This boost is primarily due to the engine’s ability to take advantage of the higher octane rating of E85.
Tuning Considerations
To fully realize the benefits of E85, proper tuning is essential. The following factors should be considered during the tuning process:
- Adjusting fuel maps to accommodate the different fuel characteristics.
- Increasing boost levels if a turbocharger is present.
- Optimizing ignition timing for improved performance.
- Ensuring that the fuel system can handle the increased flow requirements.
Supporting Modifications
In addition to tuning, several modifications can help maximize the performance gains from E85 conversion. These include:
- Upgrading fuel injectors to ensure adequate fuel delivery.
- Installing a high-flow fuel pump to support increased fuel demand.
- Improving the intercooler system to manage higher intake temperatures.
- Enhancing the exhaust system for better airflow.
Real-World Performance Results
Many enthusiasts have reported significant performance improvements after converting their FA20 engines to E85. Dyno tests have shown increases in horsepower and torque, making the vehicle more responsive and enjoyable to drive.
User Experiences
Feedback from users highlights the following benefits:
- Noticeable throttle response improvements.
- Enhanced acceleration and overall driving experience.
- Increased satisfaction with the vehicle’s performance capabilities.
Potential Drawbacks
While the benefits of E85 conversion are substantial, there are also potential drawbacks to consider:
- Availability of E85 fuel may be limited in some areas.
- Fuel economy may decrease due to the lower energy content of ethanol.
- Increased wear on fuel system components over time.
Conclusion
The FA20 engine can experience significant performance gains with E85 conversion, offering up to 40 additional horsepower. With the right tuning and supporting modifications, enthusiasts can enjoy a more powerful and responsive driving experience. However, it is essential to weigh the benefits against potential drawbacks to make an informed decision about this conversion.
