Presenting a World First – an all-carbon FK8 turbo inlet tube. We have invested months of intense R&D in developing an inlet that leaves no room for compromise. VOLUME – FLOW QUALITY – TEMPERATURE are the 3 main design criteria that we sought to meet.
1) VOLUME: Inlet Diameters – Eventuri 78mm: Stock 63mm. By maintaining the MAF section diameter from the intake through to the turbo tube we have increased the cross-sectional area by over 53% for the majority of the intake flow path to the turbo. Clearly, with significantly larger internal diameter sizes, the Eventuri tube encapsulates a much larger internal volume which de-restricts the flow path to the turbo. This allows the turbo to operate more efficiently and spool up to peak boost levels faster. It also allows the turbo to operate at peak boost with less turbine loading.
2) FLOW QUALITY: Having just a large internal volume is no good unless the flow path also allows for smooth airflow to the turbo. By using high-temperature Prepreg Carbon Fiber we have managed to achieve a smooth internal surface. In contrast, the stock inlet tube is made from cast aluminum which ends up with a rough internal surface. This coupled with the smooth curvature of the elbow results in a flow path that minimizes turbulence.
3) TEMPERATURE: The final criteria was to minimize the conduction of heat into the airflow. The stock inlet is directly connected to the turbo and so immediately conducts heat as the turbo spools. Our system uses a machined flange that connects to the turbo and then a silicon coupler with an integrated thermal spacer to keep the carbon elbow from having direct contact with the turbo. This barrier coupled with the low through-thickness thermal conductivity of carbon fiber results in less heat being transferred to the airflow.
