The 1G Eclipse, produced between 1990 and 1994, has garnered a strong following among car enthusiasts, particularly for its turbocharged variants. One of the most debated modifications for these vehicles is the installation of aftermarket intercoolers. This article explores whether aftermarket intercoolers are worth the investment by comparing core sizes and the potential power gains they provide.
Understanding Intercoolers
An intercooler is a crucial component in turbocharged engines, designed to cool the air entering the engine. Cooler air is denser, allowing for more oxygen to be packed into the combustion chamber, which can lead to increased power. In the context of the 1G Eclipse, upgrading the intercooler can potentially enhance performance significantly.
Stock vs. Aftermarket Intercoolers
The stock intercooler on the 1G Eclipse is functional but has limitations in terms of efficiency and size. Aftermarket intercoolers typically offer larger core sizes and improved designs, which can lead to better cooling performance. Here’s a comparison of the two:
- Stock Intercooler: Smaller core size, limited airflow, and less efficient heat dissipation.
- Aftermarket Intercoolers: Larger core sizes, improved airflow, and enhanced cooling capabilities.
Core Sizes Explained
Core size is a critical factor when evaluating intercoolers. The size of the core affects how much air can be cooled before entering the engine. Aftermarket options often come in various sizes, and choosing the right one can impact performance:
- Small Core (e.g., 24″x6″x3″): Suitable for stock applications, minimal gains.
- Medium Core (e.g., 28″x7″x3.5″): Balanced performance, noticeable power gains.
- Large Core (e.g., 30″x10″x3.5″): Maximum cooling potential, ideal for high-performance builds.
Power Gains from Aftermarket Intercoolers
Installing an aftermarket intercooler can lead to significant power gains, especially when paired with other modifications like a larger turbo or upgraded fuel system. The potential power increase varies based on the intercooler size and overall setup:
- Small Core: Typically yields a 5-10% increase in power.
- Medium Core: Can provide a 10-20% increase in power.
- Large Core: May result in a 20-30% increase or more, depending on the entire setup.
Considerations for Installation
When considering an aftermarket intercooler for the 1G Eclipse, there are several factors to keep in mind:
- Fitment: Ensure the intercooler fits properly within the engine bay.
- Pipework: Upgrading intercooler piping may be necessary for optimal performance.
- Budget: Aftermarket intercoolers can vary significantly in price; consider your budget before purchasing.
Conclusion
In conclusion, aftermarket intercoolers can be a worthwhile investment for the 1G Eclipse, especially for those looking to maximize performance. The benefits of increased cooling efficiency and potential power gains make them a popular choice among enthusiasts. However, it is essential to choose the right core size and consider the overall setup to achieve the best results.
