The 2018 Mustang GT is a powerful vehicle, but enthusiasts are always looking for ways to extract more performance from their rides. One effective method is upgrading the fuel system to accommodate E85 fuel, which can provide significant horsepower gains. In this article, we will explore the Holley E85 Fuel System Upgrade and how it can yield an impressive +50 wheel horsepower on your Mustang GT.
Understanding E85 Fuel
E85 is a fuel blend that consists of 85% ethanol and 15% gasoline. This high ethanol content allows for a higher octane rating, which can lead to increased performance and efficiency in modern engines designed for flex-fuel capability.
Benefits of Upgrading to E85
Switching to E85 fuel offers several advantages, particularly for performance-oriented vehicles like the Mustang GT.
- Higher Octane Rating: E85 typically has an octane rating of 100-105, reducing the chances of knock.
- Increased Power Output: The higher ethanol content allows for more aggressive tuning, resulting in more horsepower.
- Improved Cooling: Ethanol has a higher latent heat of vaporization, which can help cool the intake charge.
- Environmental Benefits: E85 can reduce greenhouse gas emissions compared to traditional gasoline.
Holley E85 Fuel System Upgrade Overview
The Holley E85 Fuel System Upgrade is designed to maximize the performance of your Mustang GT when using E85 fuel. This upgrade includes several key components that work together to ensure optimal fuel delivery and engine performance.
