The world of drag racing is constantly evolving, with enthusiasts always seeking ways to enhance performance and achieve faster times. One of the most significant transformations in recent years has been the conversion of vehicles to E85 fuel. This article explores how a Demon E85 conversion dramatically transformed a 10-second drag car, pushing the boundaries of speed and performance.
Understanding E85 Fuel
E85 is a high-performance fuel blend consisting of 85% ethanol and 15% gasoline. It offers several advantages for drag racing applications, including increased horsepower and torque, as well as improved cooling properties. Here are some key benefits of using E85:
- Higher octane rating: E85 typically has an octane rating of around 105, allowing for more aggressive tuning.
- Cooling effect: Ethanol has a higher latent heat of vaporization, which helps to cool the intake charge.
- Cost-effective: E85 is often cheaper than traditional gasoline, making it a budget-friendly option for racers.
The Demon E85 Conversion Process
Converting a drag car to run on E85 involves several modifications to the fuel system and engine management. The following steps outline the typical conversion process:
- Fuel System Upgrade: Installing larger fuel injectors and upgrading the fuel pump to accommodate the increased flow of E85.
- Tuning: Adjusting the engine management system to optimize fuel delivery and timing for E85.
- Flex-Fuel Sensor: Adding a flex-fuel sensor to monitor the ethanol content in the fuel mixture.
Performance Gains from the Conversion
After completing the E85 conversion, the results were nothing short of impressive. The drag car experienced significant performance gains, which can be attributed to several factors:
- Increased Horsepower: The higher octane rating of E85 allowed for more aggressive tuning, resulting in a noticeable increase in horsepower.
- Improved Torque: The enhanced fuel mixture provided better combustion efficiency, leading to increased torque throughout the power band.
- Faster Times: The combination of increased horsepower and torque translated into quicker elapsed times on the drag strip.
Real-World Results on the Drag Strip
To quantify the performance improvements, the drag car was tested on the strip before and after the E85 conversion. Here are the results:
- Before Conversion: The car consistently ran in the low 10-second range, with a best time of 10.3 seconds at 132 mph.
- After Conversion: Post-conversion, the car achieved a best time of 9.8 seconds at 136 mph, showcasing a significant improvement.
Challenges Faced During the Conversion
While the E85 conversion brought impressive results, it was not without challenges. Some common issues faced during the conversion process included:
- Fuel Compatibility: Ensuring that all components of the fuel system were compatible with E85 to prevent corrosion and failure.
- Tuning Complexity: Finding the right balance in tuning to maximize performance without causing engine knock.
- Availability of E85: Depending on the location, finding a reliable source of E85 can be challenging.
Conclusion
The Demon E85 conversion has proven to be a game-changer for drag racing enthusiasts looking to enhance their vehicle’s performance. With significant gains in horsepower, torque, and overall speed, this conversion demonstrates the potential of E85 as a viable fuel option for serious racers. As the drag racing community continues to innovate, the conversion to E85 will likely remain a popular choice for those seeking real-world results on the strip.
