The Subaru WRX is known for its performance and agility, but enthusiasts are always looking for ways to extract more power from their vehicles. One popular modification is the installation of an electric fan, specifically the Flex-a-Lite Electric Fan. In this article, we will explore the real-world results of this modification, highlighting a notable 15 horsepower increase.
Understanding the Flex-a-Lite Electric Fan
The Flex-a-Lite Electric Fan is designed to replace the factory mechanical fan, offering several advantages that can contribute to improved engine performance. By switching to an electric fan, the engine can run more efficiently, as it eliminates the parasitic drag caused by the mechanical fan. This allows for more power to be directed to the wheels.
Installation Process
Installing the Flex-a-Lite Electric Fan on a Subaru WRX is a straightforward process, but it requires some mechanical knowledge. Here’s a brief overview of the steps involved:
- Gather necessary tools and materials, including the Flex-a-Lite Electric Fan kit.
- Disconnect the battery to ensure safety during installation.
- Remove the factory mechanical fan and shroud.
- Install the electric fan and wiring according to the manufacturer’s instructions.
- Reconnect the battery and test the fan operation.
Real-World Testing
After completing the installation, it’s essential to test the vehicle to measure the performance gains. In a controlled environment, a Subaru WRX equipped with the Flex-a-Lite Electric Fan was put through a series of tests to evaluate horsepower improvements.
Baseline Testing
Before the installation, the WRX was dyno-tested to establish a baseline horsepower figure. The results showed a respectable output, but there was still room for improvement.
Post-Installation Testing
After installing the Flex-a-Lite Electric Fan, the same dyno testing was conducted. The results were impressive, revealing a 15 horsepower increase over the baseline figures. This significant gain illustrates the effectiveness of the electric fan in enhancing the vehicle’s performance.
Benefits of Electric Fans
Aside from the horsepower increase, there are several other benefits to installing an electric fan on a Subaru WRX:
- Improved Engine Cooling: Electric fans can provide better airflow, helping to maintain optimal engine temperatures.
- Increased Fuel Efficiency: By reducing engine load, electric fans can contribute to better fuel economy.
- Quieter Operation: Electric fans typically operate more quietly than mechanical fans, enhancing the driving experience.
- Space Saving: Electric fans are often more compact, allowing for additional modifications or easier access to engine components.
Conclusion
The installation of the Flex-a-Lite Electric Fan on a Subaru WRX has proven to be a worthwhile modification, resulting in a real-world increase of 15 horsepower. This upgrade not only enhances performance but also offers additional benefits such as improved cooling and fuel efficiency. For Subaru WRX enthusiasts looking to maximize their vehicle’s potential, the Flex-a-Lite Electric Fan is a modification worth considering.
