Converting Subaru WRX to E85: Unlocking More Power and Performance

🔥Converting a Subaru WRX to E85 fuel can result in significant power gains and improved performance.

🚀E85 fuel, a blend of ethanol and gasoline, offers a higher octane rating, allowing for increased compression ratios and improved combustion efficiency.

💪To convert a car to E85, modifications such as upgraded fuel injectors, fuel pump, and fuel lines may be necessary to handle the higher fuel flow and pressure requirements.

⛽While E85 fuel can provide more power per gallon, it has a lower energy content than gasoline, resulting in reduced fuel economy.

🏁Dyno testing of a converted Subaru WRX showed a substantial increase in horsepower, demonstrating the effectiveness of the E85 conversion.

What is E85 fuel?

—E85 fuel is a blend of 85% ethanol and 15% gasoline designed for use in Flex Fuel vehicles. It offers a higher octane rating and improved combustion characteristics.

What modifications are required to convert a Subaru WRX to E85?

—Converting a Subaru WRX to E85 may require upgraded fuel injectors, fuel pump, fuel lines, and an E85-compatible engine management system to handle the increased fuel flow and pressure.

Does running on E85 affect fuel economy?

—While E85 can provide more power and performance, it has a lower energy content than gasoline, resulting in reduced fuel economy and increased fuel consumption.

Is converting a car to E85 worth it?

—Converting a car to E85 can be beneficial for enthusiasts seeking increased power and performance. However, it is important to consider the availability and cost of E85 fuel in your area before making the conversion.

Are there any drawbacks to running on E85?

—Besides reduced fuel economy, running on E85 may require more frequent fueling, as E85 is less readily available than standard gasoline. Additionally, older non-Flex Fuel vehicles may require additional modifications and tuning to safely run on E85.
