The Dodge Hellcat is known for its incredible power and performance, but enthusiasts are always looking for ways to enhance their driving experience. One effective method to significantly increase horsepower is through the installation of a flex fuel kit that allows the use of E85 fuel. This article will explore how a flex fuel kit can boost your Hellcat’s power by up to 50 horsepower.
What is a Flex Fuel Kit?
A flex fuel kit is a modification that enables your vehicle to run on multiple types of fuel, including E85, which is a blend of 85% ethanol and 15% gasoline. This conversion allows for better combustion efficiency and can lead to significant power gains.
Benefits of Using E85 Fuel
Switching to E85 can provide several advantages for your Hellcat, enhancing both performance and efficiency. Here are some key benefits:
- Higher Octane Rating: E85 has a higher octane rating than regular gasoline, which allows for more aggressive tuning and prevents engine knock.
- Increased Power: The ability to run a richer fuel mixture can lead to power gains of up to 50 horsepower.
- Environmental Impact: Ethanol is a renewable resource, making E85 a more environmentally friendly option compared to traditional gasoline.
- Cost Efficiency: In many regions, E85 is often cheaper than premium gasoline, providing potential savings at the pump.
How Does a Flex Fuel Kit Work?
A flex fuel kit typically includes a fuel sensor, software calibration, and necessary hardware modifications. The fuel sensor detects the ethanol content in the fuel and adjusts the engine’s air-fuel mixture accordingly. This ensures optimal performance regardless of the fuel type being used.
Installation Process
Installing a flex fuel kit on your Hellcat requires some technical knowledge and tools. Here’s a general overview of the installation process:
- Gather Tools and Equipment: Ensure you have all necessary tools, including wrenches, screwdrivers, and the flex fuel kit itself.
- Remove the Fuel Lines: Safely disconnect the fuel lines from the fuel rail and pump.
- Install the Flex Fuel Sensor: Mount the flex fuel sensor in line with the fuel system.
- Update Software: Reprogram the engine control unit (ECU) to recognize the flex fuel sensor and adjust fuel mapping.
- Reassemble and Test: Reconnect the fuel lines, start the engine, and monitor for any leaks or issues.
Performance Gains and Tuning
Once the flex fuel kit is installed, tuning your Hellcat for E85 can unlock its full potential. With proper tuning, you can expect:
- Increased Horsepower: Depending on the setup, gains of up to 50 horsepower are achievable.
- Improved Throttle Response: Enhanced fuel delivery can lead to a more responsive throttle.
- Better Torque: Increased torque output can improve acceleration and overall driving experience.
Considerations Before Installation
Before installing a flex fuel kit, consider the following factors:
- Availability of E85: Ensure that E85 is readily available in your area to fully benefit from the conversion.
- Fuel System Compatibility: Check that your vehicle’s fuel system can handle the corrosive properties of ethanol.
- Insurance and Warranty: Modifications may affect your vehicle’s warranty and insurance coverage, so consult with your provider.
Conclusion
Installing a flex fuel kit on your Dodge Hellcat can be a game-changer for performance enthusiasts. With the potential for substantial horsepower gains and improved efficiency, it’s an exciting modification to consider. Always ensure that you perform the installation correctly and tune your vehicle to maximize the benefits of running on E85 fuel.
