The Subaru WRX is known for its performance and tuning potential. One of the popular modifications among enthusiasts is the installation of an electric fan. This article explores the real-world results of installing a Mishimoto electric fan in a Subaru WRX, highlighting a significant gain of 20 horsepower.
Understanding the Subaru WRX
The Subaru WRX has established itself as a favorite in the automotive community due to its turbocharged engine and all-wheel-drive system. With a focus on performance, many WRX owners look for ways to enhance their vehicle’s capabilities. Modifications like upgrading the cooling system can lead to improved performance and efficiency.
Why Upgrade to an Electric Fan?
Upgrading to an electric fan can provide several benefits over the traditional mechanical fan. Here are some reasons why enthusiasts choose electric fans:
- Weight Reduction: Electric fans are typically lighter than mechanical fans.
- Improved Engine Response: Removing the mechanical fan reduces parasitic drag on the engine.
- Better Cooling Efficiency: Electric fans can provide more consistent cooling under various conditions.
- Customizable Operation: Electric fans can be wired to operate based on temperature, improving control.
Installation of the Mishimoto Electric Fan
Installing the Mishimoto electric fan in a Subaru WRX is a straightforward process, but it requires some mechanical knowledge. Here’s a step-by-step guide to the installation:
- Gather Tools and Parts: Ensure you have the Mishimoto electric fan kit, wiring harness, and necessary tools.
- Remove the Stock Fan: Disconnect the battery, then remove the stock mechanical fan and shroud.
- Install the Electric Fan: Fit the Mishimoto fan into the shroud and secure it in place.
- Wiring: Connect the wiring harness according to the instructions provided.
- Reconnect the Battery: Once everything is secured, reconnect the battery and test the fan operation.
Measuring Performance Gains
After installation, it’s essential to measure the performance gains to see if the upgrade was worthwhile. Here’s how to accurately measure horsepower gains:
- Dyno Testing: Use a dynamometer to measure the horsepower before and after the installation.
- Track Testing: Take the vehicle to a track and measure lap times for real-world performance feedback.
- Data Logging: Utilize data loggers to track engine performance metrics during runs.
Real-World Results: 20 HP Gain
After installing the Mishimoto electric fan, many Subaru WRX owners have reported impressive results. A documented case showed a gain of 20 horsepower at the wheels, attributed to the reduced load on the engine and improved cooling efficiency.
Additional Benefits Observed
Besides the horsepower gain, several additional benefits were observed after the installation:
- Improved Engine Temperature: The electric fan maintained optimal engine temperatures during high-performance driving.
- Enhanced Throttle Response: The reduction in parasitic drag led to a more responsive throttle.
- Quieter Operation: Electric fans operate quieter than mechanical fans, leading to a more enjoyable driving experience.
Conclusion
In conclusion, upgrading to a Mishimoto electric fan in a Subaru WRX can yield significant performance improvements, including a notable 20 horsepower gain. This modification not only enhances the vehicle’s performance but also contributes to better engine efficiency and responsiveness. For WRX enthusiasts looking to maximize their vehicle’s potential, this upgrade is worth considering.
