The E63 is known for its impressive performance and luxury, but enthusiasts often seek more power from their vehicles. Upgrading the turbo system can yield significant gains, pushing the power output beyond 700 horsepower. This article explores the benefits of upgrading the intercooler and downpipe, detailing the journey from stock to a high-performance machine.
Understanding the E63 Turbo System
The E63 features a robust turbo system designed to balance performance and efficiency. However, factory components can limit the vehicle’s potential. By upgrading critical components, owners can unlock substantial power gains.
Stock Performance Overview
Stock E63 models typically produce around 550 horsepower and 700 Nm of torque. While this is impressive, many drivers desire more power for racing or spirited driving.
Benefits of Upgrading the Intercooler
The intercooler plays a crucial role in maintaining optimal air temperatures, which is vital for performance. A larger, more efficient intercooler can significantly enhance power output.
- Reduces intake temperatures for better performance
- Increases air density, leading to more power
- Improves throttle response
Choosing the Right Intercooler
When selecting an intercooler, consider the following factors:
- Core size and design
- Material quality
- Compatibility with existing turbo system
The Importance of a Downpipe Upgrade
The downpipe is another critical component that affects exhaust flow and turbo efficiency. Upgrading to a high-performance downpipe can lead to significant power gains.
- Improves exhaust flow, reducing turbo lag
- Enhances overall engine efficiency
- Can increase horsepower by 30-50 HP
Choosing the Right Downpipe
When selecting a downpipe, consider:
- Material (stainless steel vs. mild steel)
- Pipe diameter
- Whether it includes catalytic converters or not
Combining Upgrades for Maximum Power
Upgrading both the intercooler and downpipe creates a synergistic effect, unlocking the full potential of the turbo system. This combination is essential for reaching power levels of 700+ HP.
Expected Power Gains
With the right upgrades, E63 owners can expect to see:
- Stock: 550 HP
- After Intercooler Upgrade: 600-650 HP
- After Downpipe Upgrade: 650-700 HP
- With Both Upgrades: 700+ HP
Conclusion
Upgrading the intercooler and downpipe on an E63 can transform it into a powerhouse, achieving over 700 horsepower. These modifications not only enhance performance but also improve driving dynamics, making the E63 an even more thrilling vehicle to drive. For enthusiasts looking to extract maximum performance, these upgrades are essential.
