The Chevrolet Camaro is a beloved muscle car known for its performance and power. When it comes to enhancing its capabilities, particularly for those looking to achieve over 500 horsepower, upgrading the fuel system to accommodate E85 fuel is crucial. E85, a blend of 85% ethanol and 15% gasoline, allows for higher octane levels, which can lead to significant power gains. Here are the top five E85 fuel system upgrades for your Camaro.
1. High-Flow Fuel Injectors
Upgrading to high-flow fuel injectors is essential for maximizing fuel delivery. E85 requires more fuel volume than standard gasoline, and high-flow injectors ensure that your engine receives the necessary amount. Consider injectors rated for at least 850cc/min to support your horsepower goals.
2. Upgraded Fuel Pump
The stock fuel pump in many Camaros may struggle to provide the necessary fuel pressure when running E85. An upgraded fuel pump, such as a dual pump setup or a high-capacity single pump, can deliver the required flow rates to support higher horsepower levels. Look for pumps that can handle a minimum of 400 liters per hour (LPH).
3. Fuel Lines and Fittings
When switching to E85, it’s important to ensure that your fuel lines and fittings are compatible with ethanol. Upgrading to stainless steel or ethanol-rated fuel lines can prevent degradation and ensure longevity. Additionally, consider using AN fittings for a secure and leak-free connection.
4. E85-Compatible Fuel Rail
An aftermarket fuel rail designed for E85 can provide improved fuel distribution and support higher flow rates. A performance fuel rail often features larger diameter passages and can help maintain consistent fuel pressure across all injectors, which is crucial for maximizing performance.
5. Tuning for E85
After upgrading your fuel system, proper tuning is vital to fully take advantage of E85. A custom tune will optimize your engine’s air-fuel ratio, ignition timing, and other parameters to ensure the best performance and efficiency. Working with a professional tuner experienced with E85 can yield significant horsepower gains.
Conclusion
Upgrading your Chevrolet Camaro’s fuel system to support E85 can lead to impressive horsepower gains. By investing in high-flow fuel injectors, an upgraded fuel pump, compatible fuel lines, an E85-compatible fuel rail, and proper tuning, you can unlock the full potential of your Camaro. These modifications not only enhance performance but also ensure that your vehicle can handle the demands of higher ethanol content fuels.
