Eventuri Audi RS3 8V / TTRS 8S CARBON TURBO INLET

Mounting for RS3 8V Gen 2 and TTRS 8S Left and right hand drive. Finished in raw carbon - no clear coat.

Presenting a world first - a full carbon RS3/TTRS turbo intake manifold. We have invested months of intensive R&D to develop an intake that leaves no room for compromise. VOLUME - POWER QUALITY - TEMPERATURE are the 3 most important design criteria we wanted to meet.

1) VOLUME: inlet diameters - Eventuri 103 mm: stock 72 mm. Exhaust diameters - Eventuri 74 mm: stock 56.4 mm. It is clear that with significantly larger internal diameter dimensions, the Eventuri elbow encapsulates a much larger internal volume that restricts the flow path to the turbo.

2) FLOW QUALITY: Having only a large internal volume is not good unless the flow path also provides smooth airflow to the turbo. By using high temperature Prepreg Carbon Fiber we managed to achieve a smooth inner surface. The stock and other aftermarket elbows, on the other hand, are all made of cast aluminum with a rough inner surface. This combined with the smooth curvature of the elbow results in a flow path that minimizes turbulence.

3) TEMPERATURE: The final criterion was to minimize the conduction of heat in the air stream. The stock intake is directly connected to the turbo and thus conducts heat immediately as the turbo coils. Our system uses a machined flange that connects to the turbo and then a silicone coupling with an integrated thermal spacer to prevent the carbon elbow from making direct contact with the turbo. This barrier combined with the low through-thickness of carbon fiber's thermal conductivity results in less heat transfer to the airflow.
