The Subaru WRX is known for its performance and tuning potential, and one of the most effective upgrades you can make is to replace the stock top mount intercooler (TMIC) with a high-performance aftermarket option. This article will cover the installation tips and the potential power gains from such an upgrade.
Why Upgrade Your WRX Top Mount Intercooler?
Upgrading the stock TMIC can lead to significant improvements in engine performance. The stock intercooler is often a bottleneck in the WRX’s power delivery, especially when increasing boost levels. Here are some key benefits:
- Improved cooling efficiency
- Increased horsepower and torque
- Better throttle response
- Enhanced reliability under high-performance conditions
Choosing the Right Intercooler
When selecting an aftermarket TMIC for your WRX, consider the following factors:
- Core Size: A larger core size can improve cooling but may require modifications.
- Material: Look for options made from high-quality aluminum for better heat dissipation.
- Design: Some designs feature better airflow and less pressure drop.
- Brand Reputation: Choose a reputable brand known for quality and performance.
Installation Tips
Installing a new TMIC can be a straightforward process if you follow these tips:
- Gather Tools: Ensure you have all necessary tools, including sockets, wrenches, and a torque wrench.
- Read Instructions: Always refer to the manufacturer’s installation manual for specific guidelines.
- Remove the Stock Intercooler: Start by removing the engine cover, then detach the stock intercooler by loosening the clamps and bolts.
- Clean the Area: Before installing the new intercooler, clean the mounting area to ensure a proper seal.
- Install New TMIC: Position the new intercooler, secure it with bolts, and reconnect the hoses.
- Check for Leaks: After installation, check all connections for leaks before starting the engine.
Expected Power Gains
One of the most exciting aspects of upgrading your TMIC is the potential power gains. Depending on the specific intercooler and your tuning setup, you can expect:
- Horsepower Gains: Up to 50 hp with proper tuning.
- Torque Improvements: Noticeable increases in torque, especially in the mid-range.
- Better Performance: Overall improvement in acceleration and throttle response.
Post-Installation Tuning
After installing your new TMIC, it’s crucial to tune your WRX to maximize performance. A proper tune will ensure that the engine runs efficiently and safely with the new intercooler. Consider the following:
- ECU Reflash: A reflash of the ECU can optimize fuel maps and boost levels.
- Dyno Tuning: Consider a dyno session to get precise tuning for your setup.
- Monitoring: Use gauges to monitor boost levels and air-fuel ratios post-installation.
Conclusion
Upgrading the top mount intercooler on your WRX is a highly effective modification that can lead to significant power gains and improved performance. With the right intercooler, proper installation, and tuning, you can enhance your driving experience and unleash the true potential of your Subaru WRX.
