Performance Gain: Data Coming Soon
Introducing our Carbon Turbo Tube for the Honda FL5 is a direct replacement for the OEM metal turbo tube. Utilizing the same design brief as our FK8 tube, we developed the FL5 version with these 3 key objectives:
1.) VOLUME: Inlet Diameters – Eventuri 78mm at the intake end, increasing to 88mm. In comparison, the OEM tube starts at 76.5mm and then stays at this diameter before reducing to the turbo inlet. This equates to an increase in cross sectional area of over 32% at the largest point. Although the OEM FL5 tube doesn’t pose a restriction to the turbo at stock boost levels, we expect our larger tube to benefit at higher boost levels where the airflow demand is increased.
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 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.
