BMW M57 Turbo Inlet – Bionically Optimized High-Flow Inlet for the 35d Engine

Our high-flow turbo inlet for the BMW M57 35d engine was developed based on bionic flow principles to specifically optimize the airflow to the turbocharger. By using modern flow simulations and a completely revised internal geometry, pressure losses compared to the series component could be reduced by approximately 10%. At the same time, the usable fluid volume was increased by about 15%.

The optimized design enables more efficient fresh air supply to the turbocharger and creates the basis for more direct response and faster boost pressure build-up. Especially in vehicles with increased air requirements, the flow-optimized geometry can unleash its advantages.

Bionic Flow Optimization

During the development of this turbo inlet, flow quality and air throughput were the focus. Using modern flow simulations, critical areas of the series geometry were analyzed and specifically optimized.

The bionically inspired design is based on natural flow forms and enables more controlled airflow to the compressor of the turbocharger. This reduces turbulence and guides the air mass more evenly to the turbocharger.

Reduced Pressure Losses and Increased Fluid Volume

Thanks to the revised geometry, pressure losses compared to the OEM component could be reduced by approximately 10%. At the same time, the usable fluid volume was increased by about 15%.

This combination enables more efficient air supply to the turbocharger and improves the flow conditions in the intake tract. Particularly in performance-optimized vehicles, this can contribute to faster boost pressure build-up and more direct response.

Optimized for High-Performance M57 Applications

The turbo inlet was developed for vehicles where air supply requirements exceed the series design. Whether software optimization, larger intercoolers, or further hardware upgrades – low-loss airflow forms the basis for efficient supercharging.

At the same time, near-series vehicles also benefit from the optimized flow guidance and improved flow to the turbocharger.

High-Quality Manufacturing from PA12

Each turbo inlet is manufactured using high-resolution industrial 3D printing from high-quality PA12. The material convinces with its high temperature resistance, excellent chemical resistance, and excellent dimensional stability.

This makes the component ideally suited for the high thermal and mechanical loads in the engine compartment of powerful diesel engines.

Plug-&-Play Installation

The design is based on the original connection and mounting points of the BMW M57 35d. This allows the turbo inlet to be installed without adjustments and seamlessly integrated into the existing intake system.

All relevant OEM interfaces have been adopted to ensure a perfect fit installation.
