In the world of automotive performance, particularly in turbocharged vehicles like the Mitsubishi Lancer Evolution IX (Evo IX), the intercooler plays a crucial role in maintaining optimal engine performance. An efficient intercooler reduces the temperature of the compressed air from the turbocharger before it enters the engine, allowing for denser air and improved combustion. However, many Evo IX owners encounter common intercooler bottlenecks that can hinder performance. Upgrading to a larger intercooler core, such as a 28x12x3.5 inch unit, can significantly enhance charge cooling and overall vehicle performance.
Understanding Intercooler Bottlenecks
Bottlenecks in intercooler performance can arise from several factors, including design limitations, airflow restrictions, and inadequate core size. Here are some of the common issues that can affect the intercooler performance in an Evo IX:
- Poor airflow due to restrictive piping and design.
- Insufficient core size to handle increased boost levels.
- Heat soak during prolonged use, leading to higher intake temperatures.
- Low-quality materials that may not dissipate heat effectively.
Benefits of Upgrading to a 28x12x3.5 Inch Core
Upgrading to a 28x12x3.5 inch intercooler core can address many of the bottlenecks faced by Evo IX owners. Here are some of the key benefits of this upgrade:
- Improved Airflow: A larger core allows for better airflow, reducing pressure drop and enhancing turbo efficiency.
- Enhanced Cooling Capacity: The increased surface area of the intercooler core provides better heat dissipation, leading to lower intake temperatures.
- Reduced Heat Soak: A larger core can help mitigate heat soak, maintaining cooler charge temperatures during extended driving conditions.
- Better Performance: With cooler air entering the engine, the vehicle can achieve better power output and throttle response.
Installation Considerations
When considering an upgrade to a 28x12x3.5 inch intercooler, there are several installation factors that need to be taken into account:
- Fitment: Ensure that the larger intercooler fits within the existing space of the Evo IX without requiring extensive modifications.
- Piping: Upgrading the piping may be necessary to accommodate the new intercooler and ensure optimal airflow.
- Mounting Brackets: New mounting solutions may be needed to securely attach the intercooler to the vehicle.
- Intercooler Placement: Consider the placement of the intercooler to maximize airflow from the front of the vehicle.
Performance Testing and Results
After upgrading to a 28x12x3.5 inch intercooler, many Evo IX owners report noticeable improvements in performance metrics. Performance testing typically includes:
- Intake Air Temperature (IAT) Measurements: Monitoring IAT before and after the upgrade shows significant reductions in temperature.
- Dyno Testing: Many users report increased horsepower and torque figures on the dyno, attributed to the improved charge cooling.
- Real-World Driving Conditions: Drivers often note improved throttle response and acceleration during spirited driving.
Conclusion
Upgrading to a 28x12x3.5 inch intercooler core can be a game-changer for Mitsubishi Lancer Evolution IX owners looking to optimize their vehicle’s performance. By addressing common bottlenecks and enhancing charge cooling, this upgrade can lead to significant improvements in power output, responsiveness, and overall driving experience. For those looking to push their Evo IX to the next level, investing in a quality intercooler upgrade is a step worth considering.
