Bionically designed high-flow turbo inlet for more efficient air supply

The RevDop high-flow turbo inlet for the 3.0 TDI V6 EA896 Generation 2 and EA897 replaces the standard pulsation damper with a flow-optimized solution featuring bionic internal geometry.

While the stock component deflects the airflow multiple times, causing unnecessary flow losses, the newly developed geometry ensures a more uniform airflow to the compressor. The result is a more efficient air supply to the turbocharger and optimized air mass delivery, especially under increasing load.

The design was created based on extensive CFD flow simulations and subsequently verified under real-world driving conditions.

Why a flow-optimized turbo inlet?

The turbocharger can only compress the air that is supplied to it with minimal loss. Every unnecessary deflection, turbulence, or change in cross-section in the intake tract increases flow resistance and impairs the flow to the compressor wheel.

This is precisely where the RevDop turbo inlet comes into play.

Thanks to the bionically optimized internal contour, the airflow is guided in a more controlled manner, and the air mass flow is improved. As a result, the turbocharger can respond faster to load changes and provide the available air mass sooner. The elimination of the stock resonance chamber ensures less turbulence in front of the charger and reduces pressure loss.

Developed with CFD flow simulation

The stock component was digitally analyzed as early as the development phase.

Using numerical flow simulations, areas with increased turbulence and pressure losses were identified. The entire internal geometry was then redesigned to guide the airflow as uniformly as possible toward the compressor.

The result is a fluid-dynamically optimized component geometry that significantly improves the stock air ducting.

Optimized air ducting for the EA896 Generation 2 and EA897

Modern common-rail diesel engines with software optimization, in particular, place higher demands on the turbocharger's air supply.

The improved flow routing allows for more efficient airflow to the compressor, which improves air mass delivery, particularly in the lower and mid-RPM ranges.

This manifests in more spontaneous response and more harmonious power delivery.

High-quality manufacturing

Every turbo inlet is manufactured using the industrial Multi Jet Fusion process from high-quality PA12.

The material is characterized by:

• high dimensional stability
• high temperature resistance
• excellent chemical resistance
• low weight

and is ideally suited for permanent use in the engine compartment.

Plug-&-play installation

The turbo inlet replaces the stock pulsation damper without any modifications to the vehicle.

All connection and mounting points correspond to the OEM design, ensuring that installation is straightforward.
