The Ford Mustang GT is a favorite among performance enthusiasts, especially when it comes to tuning for higher horsepower. One of the most effective ways to achieve significant power gains is by upgrading to E85 fuel. This article will explore the top E85 fuel system upgrades that can help you reach 500+ horsepower on your Mustang GT.
Understanding E85 Fuel
E85 fuel is a blend of 85% ethanol and 15% gasoline, which offers a higher octane rating than traditional fuels. This allows for more aggressive tuning and increased performance. However, to make the most of E85, several upgrades to your fuel system are necessary.
Essential Upgrades for E85 Compatibility
- Fuel Pump Upgrade
- Fuel Injectors
- Fuel Lines
- Fuel Rail
- Flex Fuel Sensor
Fuel Pump Upgrade
The first step in upgrading your Mustang GT for E85 is to install a high-flow fuel pump. E85 requires more fuel volume than gasoline, and a stock pump may not be sufficient. Look for pumps that can support the horsepower goals you are targeting.
Fuel Injectors
Upgrading to larger fuel injectors is crucial when running E85. Stock injectors may not deliver enough fuel to meet the demands of increased power. Choose injectors that are compatible with E85 and have the capacity to support your horsepower goals.
Fuel Lines
Standard fuel lines may not be suitable for E85 due to the corrosive nature of ethanol. Upgrading to ethanol-safe fuel lines will ensure longevity and reliability. Look for lines made from materials that can withstand ethanol exposure.
Fuel Rail
A performance fuel rail can improve fuel distribution and support higher flow rates. An aftermarket fuel rail designed for E85 will help ensure that your engine receives the necessary fuel volume for optimal performance.
Flex Fuel Sensor
Installing a flex fuel sensor allows your Mustang GT to automatically adjust for varying ethanol content in the fuel. This upgrade is essential for maximizing performance and ensuring safe operation when using E85.
Tuning Your Mustang GT for E85
Once you have upgraded your fuel system, proper tuning is essential to unlock the full potential of E85. A professional tune will optimize fuel delivery and timing, ensuring that your Mustang GT runs efficiently and produces the desired horsepower gains.
Choosing a Tuner
Selecting an experienced tuner who understands E85 is crucial. They will be able to adjust your engine’s parameters to take full advantage of the fuel’s higher octane rating, leading to improved performance and reliability.
Monitoring Performance
After tuning, it’s important to monitor your Mustang’s performance. Use wideband O2 sensors and data logging tools to keep an eye on air-fuel ratios and overall engine health. This will help ensure that your upgrades are functioning as intended.
Benefits of E85 Fuel Upgrades
Upgrading your Mustang GT for E85 fuel not only increases horsepower but also offers several additional benefits:
- Higher octane rating allows for more aggressive tuning.
- Potential for increased torque and throttle response.
- Improved cooling properties of ethanol can enhance engine longevity.
- Environmental benefits due to reduced carbon emissions.
Conclusion
Upgrading your Mustang GT’s fuel system to support E85 can lead to significant horsepower gains. By investing in high-quality components and proper tuning, you can achieve the performance levels you desire. Remember to always monitor your engine’s performance and make adjustments as necessary to ensure reliability and efficiency.
