The N55 engine, known for its balance of performance and efficiency, has gained popularity among car enthusiasts and tuners. Upgrading the turbocharger and intercooler can significantly enhance its performance. In this article, we will explore the N55 turbo upgrade using the ETS high-flow intercooler and the impressive results that can be achieved, including reaching 370 horsepower.
Understanding the N55 Engine
The N55 is a 3.0-liter inline-six engine produced by BMW. It features a twin-scroll turbocharger, which helps to reduce turbo lag and improve throttle response. The engine is known for its smooth power delivery and has been used in various BMW models, including the 135i, 335i, 535i, and Z4. With the right modifications, the N55 can be transformed into a powerhouse.
Why Upgrade the Turbocharger?
Upgrading the turbocharger is one of the most effective ways to increase horsepower and torque in the N55 engine. A larger turbo can provide more airflow, which translates to more power. However, to fully benefit from a turbo upgrade, it’s essential to pair it with other performance parts, such as an upgraded intercooler.
Benefits of Turbo Upgrade
- Increased horsepower and torque
- Improved throttle response
- Better performance at higher RPMs
- Enhanced driving experience
Introducing the ETS High-Flow Intercooler
The ETS (Extreme Turbo Systems) high-flow intercooler is designed to improve the cooling efficiency of the intake air, which is crucial when upgrading the turbocharger. A cooler intake charge means denser air, allowing for more oxygen to enter the combustion chamber. This results in increased power output and reduced chances of engine knock.
Key Features of the ETS High-Flow Intercooler
- Large core size for maximum cooling
- Efficient design to minimize pressure drop
- Durable construction for long-lasting performance
- Direct fit for easy installation
Achieving 370 Horsepower
With the combination of the N55 turbo upgrade and the ETS high-flow intercooler, reaching 370 horsepower is an achievable goal. This power level is a significant improvement over the stock output, providing exhilarating performance on the road or track.
Performance Results
- Stock N55 horsepower: Approximately 320 HP
- Upgraded N55 horsepower: Approximately 370 HP
- Torque increase: Significant improvement across the RPM range
- Improved 0-60 mph times
Installation Process
Installing the ETS high-flow intercooler and upgrading the turbocharger requires mechanical knowledge and the right tools. It’s recommended to have a professional or experienced enthusiast perform the installation to ensure everything is done correctly.
Steps for Installation
- Remove the factory intercooler and turbocharger.
- Install the ETS high-flow intercooler in the factory location.
- Upgrade the turbocharger according to manufacturer specifications.
- Reconnect all necessary hoses and electrical connections.
- Perform a thorough check for leaks and proper operation.
Tuning for Maximum Performance
After the installation of the new turbocharger and intercooler, tuning the engine is essential to maximize performance. A proper tune ensures that the engine runs efficiently and safely at the new power levels.
Benefits of Tuning
- Optimizes air-fuel mixture for better combustion
- Adjusts ignition timing for increased power
- Enhances throttle response and drivability
- Prevents potential engine damage from excessive boost
Conclusion
The N55 turbo upgrade using the ETS high-flow intercooler is a fantastic way to unlock the full potential of this engine. With the right modifications, achieving 370 horsepower is not only possible but can also provide an exhilarating driving experience. Whether on the street or the track, this upgrade will ensure that your N55 stands out in performance and capability.
