Audi 3.0 TDI Turbo Inlet – Bionically optimized high-flow inlet with demonstrably higher air mass

Our high-flow turbo inlet for Audi 3.0 TDI engines was developed to optimize the airflow between the intake system and the turbocharger in terms of fluid dynamics and to reduce the restrictions of the standard pulsation damper.

With the help of modern CFD flow simulations and a bionically optimized internal geometry, the airflow could be specifically improved. The result is a more homogeneous flow to the compressor, reduced turbulence within the intake tract, and a more efficient supply of fresh air to the turbocharger.

In contrast to many purely theoretical optimizations, the effectiveness of our turbo inlet has been verified both on the dynamometer and through extensive log drives under real load conditions. The results show a measurably higher air mass over almost the entire usable rev range as well as significant advantages in the area around 2,000 rpm, which is particularly relevant for driving dynamics.

Bionic flow optimization

During development, the focus was on flow quality within the intake tract. Using modern CFD simulations, the fluidically critical areas of the standard component were analyzed and specifically optimized.

The bionically inspired geometry is based on natural flow principles and enables more controlled airflow to the compressor. This reduces performance-limiting turbulence and directs the air mass more evenly to the turbocharger.

The result is more efficient use of the existing intake system as well as improved air supply under load conditions.

Measurably higher air mass

Evaluation of several full-load drives shows a clear advantage over the standard pulsation damper.

From as low as approximately 1,500 rpm, the air mass increases significantly faster than with the standard component. The high-flow inlet shows a clear lead over the OEM part, particularly in the range between approximately 1,700 and 2,800 rpm.

In the area of maximum benefit, air mass increases of over 100 mg/H were measured. The air mass rises earlier, reaches higher peak values, and remains above the stock curve over wide ranges throughout the rest of the rev band.

Even in the upper rev range, the system still shows advantages over the original pulsation damper and supports a more uniform air supply to the engine.

Dynamometer results – More power where it is needed

The effectiveness of the turbo inlet was additionally verified on a power-optimized Audi 3.0 TDI with Stage 1 software on a dynamometer.

While the maximum peak power only increases slightly, the actual advantage is seen where it counts during driving: in the lower and middle rev range.

At approximately 2,000 rpm, the following improvements were measured:

• Up to +19 Nm torque
• Up to +6 HP power
• Significantly higher air mass
• Faster air mass delivery
• Improved cylinder filling

It is precisely this rev range that is used particularly frequently during acceleration and in everyday driving. The result is a more direct throttle response, more spontaneous torque buildup, and overall more dynamic power delivery.

Optimized turbocharger air supply

Efficient air supply forms the basis for powerful boost. The optimized geometry ensures more uniform flow to the compressor and allows the airflow to be guided with fewer losses.

This allows the turbocharger to react faster to load changes and provide the air mass earlier. The advantages of a flow-optimized intake are particularly evident in performance-optimized vehicles and those with increased air demand.

High-quality PA12 production

Each turbo inlet is manufactured using an industrial 3D printing process from high-quality PA12.

The material is characterized by high temperature resistance, excellent chemical resistance, and high dimensional stability, even under the thermal loads of modern turbodiesel engines.

This makes the component ideal for continuous use under demanding operating conditions.

Plug-&-Play installation

The turbo inlet was developed according to OEM specifications and adopts all relevant connection and mounting points of the standard component.

Installation requires no adjustments and it can be swapped directly for the standard pulsation damper.
