Performance Gain : 9hp, 9ft-lb peak, 15hp, 18ft-lb under 4k rpm
Introducing our updated Carbon Turbo Tube for the FK8 which is now even larger in volume, allowing the turbo to function with even less restriction and therefore unleashing even more power. Our turbo tube was designed with these 3 key objectives:
1.) VOLUME: Inlet Diameters – Eventuri 78mm at the intake end, increasing to 88mm VS Stock 63mm. Starting at the connection to the intake system, we have matched the MAF tube diameter, and this now increases to 88mm through the main section of the tube, giving an increase in cross-sectional area of 96% compared to the OEM tube. 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. We have achieved a smooth internal surface by using high-temperature Prepreg Carbon Fiber. In contrast, the stock inlet tube is made from cast aluminum 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 criterion was to minimize heat conduction into the airflow. The stock inlet is directly connected to the turbo and 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 directly contacting the turbo. This barrier, coupled with carbon fiber's low through-thickness thermal conductivity, results in less heat being transferred to the airflow.
