The Subaru WRX has long been celebrated for its performance and tuning potential. Among various upgrades, the ETS Air to Water Intercooler stands out as a significant modification that can enhance power output. In this article, we will explore how much power this intercooler can add to a Subaru WRX and the factors that contribute to its performance.
Understanding Intercoolers
An intercooler is a crucial component in forced induction systems, such as turbochargers. Its primary function is to lower the temperature of the intake air, which increases air density and improves combustion efficiency. The ETS Air to Water Intercooler employs a water cooling system, offering several advantages over traditional air-to-air intercoolers.
Benefits of the ETS Air to Water Intercooler
The ETS Air to Water Intercooler is known for its efficient heat exchange and compact design. Here are some key benefits:
- Improved Cooling Efficiency: The water cooling system can maintain lower intake temperatures, leading to better performance.
- Consistent Performance: The intercooler maintains optimal temperatures even under high load conditions.
- Space-Saving Design: Its compact size allows for more flexibility in engine bay layout.
Power Gains from the ETS Intercooler
The power gains from installing the ETS Air to Water Intercooler can vary based on several factors, including the specific model of the WRX, supporting modifications, and tuning. On average, users report power increases ranging from 15 to 30 horsepower.
Factors Influencing Power Gains
Several factors can influence the amount of power gained from the installation of an ETS intercooler:
- Turbocharger Size: Larger turbochargers can benefit more from improved cooling.
- Engine Tune: A proper tune is essential to maximize the benefits of the intercooler.
- Supporting Mods: Upgrades such as exhaust systems and intake modifications can enhance overall gains.
Installation Process
Installing the ETS Air to Water Intercooler involves several steps. It is recommended to have a basic understanding of automotive mechanics or seek professional help. Here’s a brief overview of the installation process:
- Remove the factory intercooler and associated piping.
- Install the ETS intercooler in the designated space.
- Connect the water lines for the cooling system.
- Reinstall any necessary components and check for leaks.
Tuning Considerations
After installing the ETS Air to Water Intercooler, it is crucial to tune the engine. A proper tune ensures that the vehicle runs smoothly and takes full advantage of the intercooler’s capabilities. Here are some tuning considerations:
- ECU Remapping: Adjust the engine control unit to optimize air-fuel ratios.
- Monitoring: Use gauges to monitor intake temperatures and boost levels.
- Dyno Testing: Consider a dyno session to measure power gains accurately.
Real-World User Experiences
Many Subaru WRX owners have shared their experiences after installing the ETS Air to Water Intercooler. Here are some common feedback points:
- Significant reduction in intake temperatures during aggressive driving.
- Noticeable increase in throttle response and overall power.
- Improved reliability during high-performance situations.
Conclusion
The ETS Air to Water Intercooler can provide substantial power gains for the Subaru WRX, particularly when paired with a proper tune and supporting modifications. With benefits such as improved cooling efficiency and consistent performance, it is a valuable upgrade for enthusiasts looking to enhance their vehicle’s capabilities. As always, ensure that any modifications are performed carefully and consider professional assistance for installation and tuning.
