Bionic flow guidance for the most powerful EA888 Gen.4 engines

The RevDop High-Flow Turbo Inlet has been specially developed for the higher-output EA888 Gen.4 engines from 300 hp. In these high-performance power units in particular, the air supply to the turbocharger is a decisive factor for response, power delivery, and efficiency.

While the standard turbo inlet is designed for space constraints and mass production, our High-Flow Turbo Inlet follows a strictly fluid-mechanical development approach. Using state-of-the-art CFD simulations, the complete internal geometry has been redeveloped and optimized according to bionic flow principles.

The result is significantly more homogeneous air guidance with a 26% larger fluid volume as well as up to 16% lower pressure loss compared to the OEM turbo inlet.

• Ideal for production vehicles as well as Stage 1, Stage 2, and Stage 3 setups
• Plug-&-play installation at original connection points

Developed with CFD flow simulation

The focus of development was the optimization of the internal air guidance. Through extensive Computational Fluid Dynamics (CFD) simulations, the geometry of the turbo inlet was completely redesigned.

All flow-relevant areas were analyzed and optimized with regard to pressure distribution, air speed, and flow profile. This allowed for harmonized cross-sectional changes, reduced deflection losses, and a significantly more efficient air guidance design.

Compared to the standard component, the RevDop High-Flow Turbo Inlet has around 26% more internal fluid volume. At the same time, the flow-optimized internal geometry reduces pressure loss by up to 16%.

The intake air therefore reaches the turbocharger more evenly and with less resistance – the foundation for more efficient operation of the entire intake system.

Bionic flow guidance

The heart of our turbo inlet is the bionically developed internal geometry.

Instead of simply routing air through a larger cross-section, the entire flow path has been specifically optimized. The air is guided to the compressor in a more controlled manner, which reduces turbulence and local pressure differences.

Especially in high-performance engines from 300 hp, which handle significantly higher air masses than the lower-output versions, this optimized flow guidance contributes to a more stable air supply for the turbocharger.

Developed for high air masses

As engine performance increases, so do the demands on the intake system.

The RevDop High-Flow Turbo Inlet was developed specifically for the higher air throughput of the 300+ hp versions and supports the turbocharger through a more uniform inflow.

Particularly in modified vehicles or under high load, the optimized air guidance helps to utilize existing hardware more efficiently and minimize unnecessary flow losses.

High-quality manufacturing from PA12

The turbo inlet is made of high-quality PA12, a technical plastic that has proven itself in motorsport due to its excellent material properties.

The advantages:

• High temperature resistance
• High mechanical strength
• Resistance to oil and fuel vapors

Manufacturing takes place using a high-resolution industrial 3D printing process via laser sintering, ensuring a precise fit at the original connection points.

Plug & Play installation

The RevDop High-Flow Turbo Inlet replaces the standard component completely.

Installation is carried out at the original mounting and connection points. No additional adjustments to the vehicle are required.

Suitable for

Suitable for vehicles of the Volkswagen Group with EA888 Gen.4 engine in the higher-output 300 hp and above versions.

Compatibility depends on the engine code and the installed turbocharger. Please check the vehicle assignment in the technical data or contact us before purchasing.
