Our turbo tube was designed with these 3 key objectives:\u003c\/p\u003e\n\u003cp\u003e1) 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. 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.\u003c\/p\u003e\n\u003cp\u003e2) 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 aluminium which ends up with a rough internal surface. This coupled with the smooth curvature of the elbow results in a flow path which minimises turbulence.\u003c\/p\u003e\n\u003cp\u003e3) TEMPERATURE : The final criteria was to minimise 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 which 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.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0809\/6684\/4690\/files\/53573824757_c8f4a56bbf_o-1-1024x699.webp?v=1778594028\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"UTF-8\"\u003e\u003cspan\u003eOur new Turbo Tube was independently tested at Dream Automotive on an FK8 with stage 1 mapping. All runs had the same map and our intake system and were done on the same day, back to back. The OEM tube was tested to set a baseline and then changed to the V1 tube. This showed a 4hp increase at the peak RPM as expected. We then changed it to the new V3 tube and a further 5hp was gained over the V1 tube at the peak, which equates to 9hp over the OEM tube. This is around double the power gained in comparison to the previous version. Since the volume is larger, we expect even more gains with high power builds demanding where the turbo demands more airflow.\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Eventuri FK8 Carbon Turbo Tube consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards. We use 100% pre-preg carbon fiber with no fibreglass which means we can achieve a smooth internal surface to maintain smoother airflow.
