The Subaru WRX is a popular choice among car enthusiasts, particularly for those looking to enhance their vehicle’s performance. One of the most effective upgrades for achieving higher horsepower is the installation of a top mount intercooler (TMIC). The COBB Tuning WRX Top Mount Intercooler is designed to deliver optimal cooling efficiency, making it a prime choice for those aiming for 350+ horsepower. This article will guide you through the tuning process for maximizing the performance of your COBB TMIC.
Understanding the Importance of an Intercooler
An intercooler is essential for turbocharged engines, as it cools the air compressed by the turbocharger before it enters the engine. Cooler air is denser, allowing for more oxygen to be packed into the combustion chamber, which translates to more power. The COBB Tuning WRX TMIC is engineered to provide significant improvements in cooling efficiency over the stock intercooler.
Benefits of the COBB Tuning WRX Top Mount Intercooler
- Improved Cooling Efficiency: The larger core size allows for better heat dissipation.
- Reduced Pressure Drop: Enhanced airflow leads to less turbo lag.
- Durability: Constructed with high-quality materials for longevity.
- Easy Installation: Designed for a straightforward bolt-on fitment.
Preparing for Installation
Before installing the COBB TMIC, it’s crucial to gather the necessary tools and parts. Here’s what you’ll need:
- Socket set
- Torque wrench
- Flathead and Phillips screwdrivers
- Intercooler couplers
- Clamps
Ensure your vehicle is parked on a level surface and the engine is cool before starting the installation process. Disconnect the battery to prevent any electrical issues during the installation.
Step-by-Step Installation Guide
1. Remove the Stock Intercooler
Begin by removing the stock intercooler. This involves disconnecting the associated piping and hoses. Use your socket set to remove the bolts securing the intercooler to the engine. Carefully lift the stock intercooler out of the engine bay.
2. Prepare the COBB TMIC
Before installing the new intercooler, attach the couplers to the inlet and outlet of the COBB TMIC. Secure them with clamps, ensuring a tight fit to prevent any boost leaks.
3. Install the COBB TMIC
Carefully position the COBB TMIC in the engine bay, aligning it with the mounting points. Use the original bolts to secure the intercooler in place, tightening them to the manufacturer’s specifications using a torque wrench.
4. Reconnect the Piping and Hoses
Reconnect all piping and hoses to the COBB TMIC. Ensure that all connections are secure and that there are no kinks in the hoses. Double-check that all clamps are tightened properly to avoid boost leaks.
5. Reconnect the Battery
Once everything is securely in place, reconnect the battery. This will allow you to start the vehicle and check for any issues.
Tuning for 350+ HP
After installing the COBB TMIC, tuning the vehicle is essential to unlock its full potential. Here are the key aspects to consider:
- ECU Reflash: Use a COBB Accessport to reflash the ECU with a performance map tailored for the TMIC.
- Boost Levels: Adjust boost levels to optimize performance without risking engine damage.
- Fuel Maps: Ensure the fuel maps are adjusted to provide the correct air-fuel ratio for increased horsepower.
- Monitoring: Use gauges to monitor boost pressure, air-fuel ratio, and engine temperatures during tuning.
Testing and Fine-Tuning
After tuning, it’s crucial to test the vehicle to ensure everything functions correctly. Here’s how to effectively test your WRX:
- Dyno Testing: Use a dynamometer to measure horsepower and torque output accurately.
- Road Testing: Take the vehicle for a test drive, paying attention to throttle response and boost levels.
- Data Logging: Utilize the Accessport to log data during your test drive for further analysis.
Conclusion
The COBB Tuning WRX Top Mount Intercooler is a powerful upgrade for anyone looking to push their Subaru WRX to 350+ horsepower. With proper installation and tuning, you can significantly enhance your vehicle’s performance, ensuring a thrilling driving experience. Remember to monitor your vehicle’s performance and make adjustments as necessary to maintain reliability and efficiency.
