The Subaru WRX is a beloved performance car known for its rally heritage and turbocharged power. As enthusiasts seek to enhance their vehicles, upgrading the clutch is a crucial step, especially for those aiming for 400+ horsepower. In this article, we will explore the top power mods for a WRX clutch upgrade to ensure you achieve that power safely and effectively.
Understanding the Importance of a Clutch Upgrade
A clutch upgrade is essential when increasing the power of your WRX. The stock clutch may struggle to handle the increased torque and power, leading to slippage, reduced performance, and potential damage. Upgrading your clutch helps maintain power delivery, improves driving feel, and enhances overall performance.
Key Factors to Consider for a Clutch Upgrade
- Power Goals: Determine your horsepower and torque targets.
- Driving Style: Consider whether you drive on the street, track, or both.
- Material: Choose between organic, ceramic, or metallic clutches based on performance needs.
- Weight: Lighter clutches can improve throttle response but may sacrifice drivability.
Top Power Mods for WRX Clutch Upgrade
1. High-Performance Clutch Kit
A high-performance clutch kit is the foundation of any clutch upgrade. Look for kits that offer increased clamping force and better heat resistance. Brands like ACT, Exedy, and South Bend offer reliable options that can handle the power associated with 400+ hp.
2. Lightweight Flywheel
Upgrading to a lightweight flywheel can improve throttle response and reduce engine load. This modification allows the engine to rev more freely, enhancing acceleration. However, it may result in a slightly harsher engagement, so consider your driving preferences.
3. Upgraded Master and Slave Cylinders
To ensure smooth engagement and disengagement of the clutch, consider upgrading the master and slave cylinders. These components can provide a more precise clutch feel and can handle the increased hydraulic pressure from a performance clutch.
4. Performance Clutch Line
A performance clutch line, often made of stainless steel, can improve clutch pedal feel and responsiveness. This upgrade minimizes flex in the line, ensuring that more of the hydraulic force is transmitted directly to the clutch.
5. ECU Tune
After installing a new clutch, an ECU tune is essential to optimize performance. A proper tune can adjust fuel maps, boost levels, and ignition timing to ensure that your WRX runs smoothly with the new clutch setup and maximizes power delivery.
6. Turbo Upgrade
To achieve 400+ hp, consider upgrading your turbocharger. A larger turbo can provide the necessary airflow to support higher horsepower levels. Popular options include the Garret GT series or the BorgWarner EFR series, which offer excellent performance and reliability.
7. Intercooler Upgrade
As you increase power, keeping intake temperatures low is crucial. Upgrading to a larger intercooler can help maintain efficiency and prevent heat soak, ensuring that your WRX can sustain higher power levels without losing performance.
8. Exhaust System Upgrade
A high-flow exhaust system can reduce back pressure and improve turbo spool time. Upgrading to a cat-back exhaust or a turbo-back system can significantly enhance both sound and performance, allowing your WRX to breathe better at higher horsepower levels.
Maintaining Your Upgraded Clutch
After upgrading your clutch and power components, proper maintenance is vital. Regularly check for signs of wear, and ensure that your hydraulic system is functioning correctly. Additionally, consider using high-quality fluids to prolong the life of your clutch.
Conclusion
Upgrading the clutch in your WRX is a critical step in achieving 400+ horsepower safely. By selecting the right components and considering your performance goals, you can enjoy enhanced power delivery and an exhilarating driving experience. Remember to maintain your upgrades for optimal performance and longevity.
