The E63 is a remarkable vehicle, known for its blend of luxury and performance. However, for enthusiasts looking to push the boundaries of power, upgrading the turbo system is a popular choice. This article will explore how to achieve 650-700 horsepower through upgraded internals and larger compressor wheels.
Understanding the E63 Turbo System
The E63 is equipped with a factory turbo system that provides impressive performance right out of the box. However, for those seeking more power, understanding the components of the turbo system is essential.
- Turbocharger: The heart of the forced induction system.
- Compressor Wheel: Responsible for drawing in and compressing air.
- Internals: Components like pistons and rods that can handle increased power.
Benefits of Upgrading Internals
Upgrading the internals of the engine is crucial when aiming for higher horsepower. Stock internals may not withstand the increased stress from higher boost levels. Here are the key benefits:
- Durability: Upgraded pistons and rods can handle higher power output.
- Performance: Improved internal components can enhance engine efficiency.
- Reliability: Reduces the risk of engine failure under high-stress conditions.
Choosing the Right Internals for Your E63
When selecting upgraded internals, it’s vital to choose components that are compatible with your specific E63 model. Here are some recommended upgrades:
- Pistons: Forged pistons are ideal for high horsepower applications.
- Connecting Rods: Upgraded rods provide strength and reliability.
- Cylinder Head: Porting and polishing can improve airflow.
Larger Compressor Wheels: The Key to Increased Power
Larger compressor wheels are essential for achieving higher horsepower levels. They allow for greater airflow, which translates to more power. Here’s what to consider when upgrading:
- Size: Choose a compressor wheel that balances performance and drivability.
- Material: Lightweight materials can improve spool time and efficiency.
- Design: Consider the design of the wheel for optimal airflow characteristics.
Installation Considerations
Installing upgraded internals and larger compressor wheels requires careful planning and execution. Here are some considerations:
- Professional Installation: It’s advisable to have a professional handle the installation to ensure everything is done correctly.
- Tuning: After installation, a proper tune is necessary to maximize performance and ensure reliability.
- Supporting Mods: Consider upgrading other components such as fuel injectors and intercoolers for optimal performance.
Tuning Your E63 for Maximum Performance
Tuning is a critical step after upgrading your turbo system. A proper tune can significantly affect performance and reliability. Here are some tuning tips:
- ECU Remapping: Adjust the engine’s ECU settings to accommodate the new turbo setup.
- Air-Fuel Ratio: Ensure the air-fuel mixture is optimized for the increased airflow.
- Boost Levels: Monitor and adjust boost levels to prevent engine damage.
Maintaining Your Upgraded E63
Once you have upgraded your E63, maintenance becomes even more critical. Here are some maintenance tips to keep your vehicle running smoothly:
- Regular Oil Changes: Use high-quality oil to protect your engine.
- Monitor Boost Levels: Keep an eye on boost levels to avoid over-boosting.
- Cooling System: Ensure the cooling system is functioning properly to prevent overheating.
Conclusion
Upgrading the turbo system on your E63 to achieve 650-700 horsepower is an exciting journey for any automotive enthusiast. By focusing on upgraded internals and larger compressor wheels, along with proper tuning and maintenance, you can unlock the full potential of your vehicle. Always remember to prioritize quality components and professional installation for the best results.
