The quest for power in high-performance vehicles like the Nissan GT-R and Toyota Supra often leads enthusiasts to consider clutch and drivetrain upgrades. When pushing beyond 700 horsepower, the stock components may struggle to handle the increased torque and power, making upgrades essential for optimal performance and reliability.
Understanding the Importance of Clutch and Drivetrain Upgrades
Both the GT-R and Supra are known for their impressive engineering, but as horsepower increases, the need for enhanced power transfer becomes critical. Upgrading the clutch and drivetrain components can lead to:
- Improved power handling
- Enhanced driving experience
- Increased reliability under stress
- Better acceleration and responsiveness
Clutch Upgrades
The clutch is a vital component in transferring power from the engine to the drivetrain. For vehicles with over 700 hp, stock clutches often fail to cope with the demands placed on them. Here are some popular clutch upgrades for both the GT-R and Supra:
- Single Disc Clutch: A lightweight option that offers quicker engagement and reduced rotational mass.
- Multi-Disc Clutch: Designed for high horsepower applications, providing superior grip and heat dissipation.
- Upgraded Pressure Plate: Increases clamping force, ensuring better engagement and reducing slip.
- Performance Clutch Kits: Comprehensive kits that include all necessary components for a complete upgrade.
Nissan GT-R Clutch Options
For the GT-R, several aftermarket options are available, including:
- Exedy Stage 1 Clutch: Ideal for street use with increased torque capacity.
- OS Giken Twin Plate Clutch: Excellent for track use, offering high performance and durability.
- ACT Heavy Duty Clutch: Provides a balance of streetability and performance for daily drivers.
Toyota Supra Clutch Options
The Supra also has a variety of clutch options to suit different performance needs:
- Clutch Masters FX400: A great choice for street and mild track use, offering increased holding capacity.
- ACT 6-Puck Clutch: Designed for high-performance applications, providing quick engagement.
- South Bend Stage 2 Clutch: A versatile option for those who want a balance of performance and drivability.
Drivetrain Upgrades
In addition to clutch upgrades, enhancing the drivetrain is crucial for maximizing power transfer. Key components to consider include:
- Driveshaft: Upgrading to a lightweight, high-strength driveshaft can reduce rotational mass and improve response.
- Differential: A limited-slip differential (LSD) can enhance traction and improve cornering performance.
- Axles: Upgraded axles are necessary to handle the increased torque and power, preventing breakage.
- Transmission: A performance transmission can improve shifting speed and reliability under high power conditions.
Nissan GT-R Drivetrain Options
The GT-R’s drivetrain can be enhanced with the following components:
- Carbon Fiber Driveshaft: Reduces weight and increases strength, improving overall performance.
- OEM GT-R LSD: Provides better grip and handling, especially in high-speed cornering situations.
- Upgraded Transmission Cooler: Ensures optimal operating temperatures during high-performance driving.
Toyota Supra Drivetrain Options
For the Supra, consider these drivetrain upgrades:
- Aluminum Driveshaft: Lightweight and strong, it helps reduce rotational inertia.
- Wavetrac LSD: Provides excellent traction and handling characteristics for both street and track.
- Heavy-Duty Axles: Designed to withstand high horsepower applications without failure.
Conclusion
Upgrading the clutch and drivetrain components is essential for those looking to extract maximum performance from their 700+ hp GT-R or Supra. By investing in quality parts, enthusiasts can ensure improved power transfer, reliability, and an exhilarating driving experience. Whether you’re on the street or the track, these upgrades will help you harness the full potential of your high-performance vehicle.
