The Subaru WRX is renowned for its performance and handling capabilities. However, when converting to E85 fuel, maintaining power stability becomes crucial. One of the most effective ways to achieve this is through high-performance intercooler and radiator upgrades. In this article, we will explore the importance of these upgrades and the best options available for WRX E85 conversions.
Understanding the Need for Upgrades
When switching to E85, the fuel mixture changes significantly, requiring adjustments to the vehicle’s cooling system. E85 has a higher ethanol content, which can lead to increased engine temperatures and potential power loss without adequate cooling solutions. Upgrading the intercooler and radiator ensures that your WRX maintains optimal performance under these new conditions.
Benefits of High-Performance Intercoolers
A high-performance intercooler plays a vital role in cooling the intake air charge, which is essential for maximizing engine efficiency and power. Here are some of the key benefits of upgrading your intercooler:
- Improved Cooling Efficiency: High-performance intercoolers are designed to provide better heat dissipation, allowing for cooler air intake temperatures.
- Increased Power Output: Cooler air leads to denser air-fuel mixtures, resulting in improved combustion and higher power levels.
- Enhanced Reliability: Upgraded intercoolers can handle higher boost levels without compromising performance or reliability.
Choosing the Right Intercooler for Your WRX
When selecting an intercooler for your WRX E85 conversion, consider the following factors:
- Size and Fitment: Ensure the intercooler fits within the engine bay without obstructing other components.
- Core Design: Look for a bar-and-plate design which offers better cooling efficiency compared to tube-and-fin designs.
- Material Quality: Choose intercoolers made from lightweight yet durable materials like aluminum.
High-Performance Radiator Upgrades
Alongside intercooler upgrades, enhancing your WRX’s radiator is equally important when converting to E85. A high-performance radiator can significantly improve cooling capacity, ensuring that your engine operates within safe temperature ranges.
Why Upgrade Your Radiator?
Upgrading your radiator provides several advantages:
- Increased Cooling Capacity: High-performance radiators often have larger cores and more efficient designs, allowing for better heat dissipation.
- Improved Durability: Upgraded radiators are built to withstand higher pressure and temperature, reducing the risk of failure.
- Enhanced Flow Rate: A better flow rate ensures that coolant circulates more effectively, keeping engine temperatures stable.
Top Radiator Options for WRX E85 Conversions
Here are some top radiator options that are ideal for WRX E85 conversions:
- Mishimoto Performance Radiator: Known for its high-quality construction and superior cooling capabilities.
- Grimmspeed Radiator: Offers a perfect balance of performance and fitment, designed specifically for WRX models.
- CSF Racing Radiator: Provides excellent heat dissipation and is engineered for high-performance applications.
Installation Considerations
When upgrading your intercooler and radiator, proper installation is crucial. Here are some tips to ensure a successful upgrade:
- Follow Manufacturer Instructions: Always refer to the installation manual provided by the manufacturer for specific guidelines.
- Use Quality Hardware: Invest in high-quality hoses and clamps to ensure a secure fit and prevent leaks.
- Check for Interference: Before finalizing the installation, check for any potential interference with other engine components.
Conclusion
Upgrading your WRX’s intercooler and radiator is essential for maintaining power stability during an E85 conversion. By investing in high-performance components, you can ensure that your engine stays cool and efficient, maximizing the benefits of E85 fuel. Choose the right upgrades, follow proper installation practices, and enjoy the enhanced performance of your WRX.
