The ETS 27-inch WRX front mount intercooler has become a popular modification among Subaru enthusiasts, particularly those looking to enhance the performance of their WRX models. One of the most frequently asked questions is whether this intercooler can genuinely increase power by 50 horsepower. In this article, we will explore the functionality of intercoolers, the specific benefits of the ETS model, and whether the claimed power gains are realistic.
Understanding Intercoolers
Intercoolers play a crucial role in turbocharged engines. They cool the air that has been compressed by the turbocharger before it enters the engine. Cooler air is denser, which allows for more oxygen to be packed into the combustion chamber, leading to improved combustion efficiency and power output.
How Intercoolers Work
The basic operation of an intercooler involves the following steps:
- The turbocharger compresses the intake air, increasing its temperature.
- This hot air passes through the intercooler, where it is cooled by ambient air.
- The cooled air then enters the engine, allowing for a more efficient combustion process.
Benefits of the ETS 27-Inch WRX Front Mount Intercooler
The ETS 27-inch front mount intercooler offers several advantages over stock intercoolers. These include:
- Increased Cooling Efficiency: The larger core size allows for more surface area, leading to better heat dissipation.
- Improved Airflow: The design of the intercooler minimizes restrictions, allowing for a smoother flow of air.
- Durability: Made from high-quality materials, the ETS intercooler is built to withstand higher pressures and temperatures.
Installation Considerations
Installing the ETS intercooler requires some mechanical knowledge. Key considerations include:
- Compatibility with your specific WRX model year.
- Potential need for additional modifications to the piping and mounting locations.
- Professional installation may be recommended for optimal results.
Power Gains: Myth or Reality?
The claim that the ETS 27-inch intercooler can increase power by 50 horsepower is a significant point of contention among car enthusiasts. While intercoolers do contribute to performance gains, several factors influence the actual horsepower increase.
Factors Affecting Power Gains
Several elements can affect the extent of power gains from installing an intercooler:
- Supporting Modifications: Power gains are often maximized when combined with other performance upgrades, such as a better exhaust system or upgraded turbocharger.
- Tuning: Proper tuning of the engine management system is essential to realize the full potential of the intercooler.
- Environmental Conditions: Ambient temperature and altitude can also impact performance and power output.
Real-World Testing and Results
To determine if the 50 horsepower claim holds true, various performance tests and dyno runs have been conducted by enthusiasts and automotive experts. The results often vary, but common findings include:
- Power gains typically range from 20 to 35 horsepower with the ETS intercooler alone.
- Significant increases can be observed when paired with additional modifications and proper tuning.
- Some users report achieving close to the 50 horsepower mark, but these cases often involve extensive modifications.
Conclusion
While the ETS 27-inch WRX front mount intercooler is a valuable upgrade that can enhance performance, the claim of a 50 horsepower increase should be taken with caution. The actual power gains depend on various factors, including supporting modifications and tuning. For those looking to maximize their WRX’s potential, the ETS intercooler is a worthy investment, especially when combined with other performance enhancements.
