The Mitsubishi Lancer Evolution, commonly known as the Evo, is a beloved platform among automotive enthusiasts. With its impressive performance capabilities, many owners look to enhance their vehicles further. One crucial component that can significantly impact performance is the clutch. In this article, we will compare the stock clutch to aftermarket options for Evo models tuned to around 350 horsepower, focusing on street and track use.
Understanding Clutch Functionality
The clutch plays a vital role in transferring power from the engine to the drivetrain. It engages and disengages the engine’s power, allowing for smooth gear changes. For high-performance applications, the choice of clutch can affect acceleration, shifting speed, and overall driving experience.
Stock Clutch Overview
The stock clutch in the Evo is designed to handle the power output of the factory engine. It provides a balance between performance and drivability, making it suitable for daily driving and occasional spirited runs.
- Material: Typically made from organic materials for a smooth engagement.
- Torque Capacity: Adequate for stock power levels, usually around 300 lb-ft.
- Pedal Feel: Light and manageable, ideal for everyday use.
- Longevity: Designed for durability but may wear out quickly under increased power.
Aftermarket Clutch Options
Aftermarket clutches offer various benefits, including increased torque capacity, improved engagement, and enhanced durability. However, they can also come with trade-offs in terms of drivability and pedal feel.
Types of Aftermarket Clutches
- Performance Clutch Kits: Designed for high horsepower applications, these kits often include a heavy-duty pressure plate and a performance disc.
- Single vs. Twin Disc: Single disc clutches are more common and easier to install, while twin disc setups provide higher torque capacity and quicker engagement.
- Material Options: Aftermarket clutches may use materials like ceramic or Kevlar for better heat resistance and performance.
Recommended Aftermarket Clutch Brands
- Exedy: Known for reliable performance clutches, Exedy offers various options suitable for 350 hp applications.
- ACT (Advanced Clutch Technology): Provides a range of clutches designed for both street and track use, focusing on durability and performance.
- Clutch Masters: Offers high-performance clutches with options for both single and twin disc setups.
Comparative Analysis: Stock vs. Aftermarket
When comparing stock and aftermarket clutches, several factors come into play, including performance, drivability, and cost. Understanding these differences can help owners make informed decisions based on their specific needs.
Performance
Aftermarket clutches typically offer higher torque capacities, allowing them to handle increased power without slipping. This is especially important for modified Evo models pushing 350 hp.
Drivability
While aftermarket clutches can provide better performance, they often come with a stiffer pedal feel and harsher engagement characteristics. This can make daily driving less comfortable compared to the stock clutch.
Cost Considerations
Stock clutches are generally more affordable, but they may require replacement sooner under high-stress conditions. Aftermarket options can be more expensive initially but may offer better longevity and performance, making them a worthwhile investment for serious enthusiasts.
Choosing the Right Clutch for Your Needs
When selecting a clutch for your Evo, consider your driving style, power goals, and how you plan to use the vehicle. If you primarily drive on the street with occasional track days, a performance-oriented single disc clutch may be ideal. For dedicated track use, a twin disc setup could provide the performance needed to handle higher power levels.
Installation and Maintenance Tips
Proper installation of the clutch is crucial for optimal performance. Here are some tips to consider:
- Professional Installation: If you’re not experienced, consider hiring a professional to ensure the clutch is installed correctly.
- Break-In Period: Follow the manufacturer’s recommendations for breaking in a new clutch to avoid premature wear.
- Regular Inspections: Check the clutch system regularly for signs of wear, especially if you track your vehicle.
Conclusion
The choice between a stock and aftermarket clutch for a 350 hp Evo ultimately depends on individual preferences and driving needs. While stock clutches offer a balance of performance and comfort, aftermarket options can provide enhanced capabilities for those looking to maximize their vehicle’s potential on both the street and the track.
