When it comes to upgrading your Mitsubishi Lancer Evolution’s intercooler, size matters. The choice between a 24x12x3 and a 26x12x3 intercooler can significantly impact your vehicle’s performance. In this article, we will explore the differences, benefits, and key considerations for each option, helping you make an informed decision for peak power gains.
Understanding Intercooler Functionality
An intercooler plays a crucial role in the performance of turbocharged engines. It cools the air that has been compressed by the turbocharger, reducing its temperature before it enters the engine. Cooler air is denser, which means more oxygen molecules are available for combustion, leading to improved power output.
Comparing Intercooler Sizes
24x12x3 Intercooler
The 24x12x3 intercooler is a popular choice among Evo enthusiasts. With its compact size, it fits well in the engine bay while still providing substantial cooling benefits.
- Dimensions: 24 inches wide, 12 inches tall, 3 inches thick
- Weight: Lighter than larger options, aiding in overall vehicle performance
- Cooling Efficiency: Adequate for moderate power upgrades
This intercooler is ideal for those who are looking for a balance between performance and ease of installation. It can support moderate power gains while maintaining reasonable temperatures during spirited driving.
26x12x3 Intercooler
The 26x12x3 intercooler offers a larger surface area, which can lead to better cooling performance, especially under high boost conditions.
- Dimensions: 26 inches wide, 12 inches tall, 3 inches thick
- Weight: Heavier than the 24x12x3, which may affect vehicle dynamics
- Cooling Efficiency: Superior cooling capabilities for higher power levels
This intercooler is more suited for those pushing the limits of their Evo’s performance, especially for track use or high-horsepower builds. The increased size allows for better heat dissipation, leading to more consistent power delivery.
Key Considerations When Choosing an Intercooler
- Power Goals: Determine what power level you aim to achieve with your Evo.
- Installation Space: Ensure that the intercooler fits within your engine bay without requiring extensive modifications.
- Weight Distribution: Consider how the weight of the intercooler may affect overall vehicle handling.
- Cooling Needs: Assess whether your driving style requires more aggressive cooling solutions.
Performance Gains from Each Intercooler
Both intercooler options offer distinct performance gains, but the extent of these gains can vary based on individual setups and tuning. Below, we break down the potential improvements you can expect from each size.
Expected Gains with the 24x12x3 Intercooler
The 24x12x3 intercooler can provide a noticeable improvement in throttle response and power delivery, particularly for those running stock to moderately tuned setups.
- Peak Power Increase: Typically around 15-30 whp depending on the setup
- Temperature Drop: Can reduce intake temperatures by 10-20 degrees Fahrenheit
Expected Gains with the 26x12x3 Intercooler
The 26x12x3 intercooler can significantly enhance performance, especially for higher horsepower builds. It allows for more aggressive tuning and boost levels.
- Peak Power Increase: Can yield gains of 30-50 whp or more
- Temperature Drop: May lower intake temperatures by 20-30 degrees Fahrenheit
Installation Process
Installing an intercooler requires some mechanical skills and tools. Here’s a brief overview of the installation process for both intercooler sizes.
- Remove the Stock Intercooler: Disconnect all piping and mounting hardware.
- Prepare the New Intercooler: Ensure all fittings and connections are compatible.
- Install the New Intercooler: Secure it in place and connect the piping.
- Check for Leaks: Start the vehicle and inspect for any air leaks.
Conclusion
Choosing between a 24x12x3 and a 26x12x3 intercooler ultimately depends on your specific performance goals and driving style. The 24x12x3 is suitable for moderate builds, while the 26x12x3 is better for those seeking maximum performance. Regardless of your choice, upgrading your intercooler will lead to improved engine efficiency and power output.
