Description Each component has been designed to provide the turbo with a smooth and free flowing path. The intake tube has an internal diameter of 103mm or just over 4″ and has a smooth curvature from the filter housing all the way to the turbo inlet. The filter itself has been specifically designed for this intake and has a huge outer diameter of 210mm or 8.3″ with a filtration surface area of over 130,000mm^2. The patented Venturi housing has been designed to provide the maximum internal volume possible for the RS3 engine bay space available and provides laminar flow to the turbo tube. Finally the duct seals the filter opening to the front slam panel but is not restricted by just the stock entry feed. Eventuri have lifted the front of the duct to now provide an extra opening behind the hood which is equivalent to an extra 7″ diameter hole for the intake to draw from. The resulting system has the capability of flowing 840 CFM at 28″ H2O while keeping intake temperatures at a minimum with the sealed design. Each intake system consists of: Carbon Fiber Patented Venturi Filter Housing with 103mm Outlet Bespoke High Flow Dry Cone Filter Carbon Fiber Inlet Duct Carbon Fiber Tube with 103mm ID OPF (DWNA) Breather adapter Heat Shield with Gold Reflective Backing Laser Cut Stainless Steel Brackets Silicon Breather Hose Silicon Couplers and Reducer The Stage 3 filter housing comprises of a bespoke high flow filter, aluminium cowl, laser cut brackets and the carbon pod itself. The carbon pod shrouds the reverse mounted filter and smoothly shape the airflow down to the intake tubes. This smooth reduction in cross sectional area invokes the Venturi effect where the airflow accelerates whilst maintaining laminar conditions. It can be thought of as a large velocity stack. In order to achieve the highest flow rate possible Eventuri had to redesign their stage 2 filter and increase the size to as large as was possible. The resulting filter has an outside diameter of 210mm or 8.3″ and when flow tested with just the carbon housing is able to flow up to 940 CFM at 28″ H2O. The filter medium is ISO tested to ensure that filtration is in line with OEM standards and is also dry. The filter is constructed with their signature flow cones to aid in the Venturi housing principle. The duct channels ambient air from the slam panel area to the filter housing. It fits inside the OEM ducting system and smoothly transitions to the circular filter housing shape. In order to ensure a good seal against engine bay heat – it also has a flexible rubber edging around the opening which presses against the filter housings creating the desired seal yet allowing the housing to move with the engine. Since this was designed to support high power builds, Eventuri found that the stock openings in the slam panel could cause a restriction at high flow demand. They lifted the top surface of the duct and created an opening above the slam panel which is able to draw in cold air from behind the hood shut. This extra opening is equivalent to a hole with a diameter of over 7″ and completely de-restricts the stock cold air feed. The stage 3 duct was designed to have the maximum internal volume possible within the given geometry of the engine bay. This ensures that the filter housing is able to draw with minimum restriction. The intake tube is crafted from 100% prepreg carbon fiber and so as mentioned the internal surface is smooth and the carbon weave can be seen. The stage 3 tube has an internal diameter of 103mm or 4″ and has a smoooth curvature to minimise pressure drop. It channels airflow from the Venturi housing to the turbo inlet. The smooth bend geometry ensures laminar flow is maintained from the filters to the exits. Due to the intense heat generated by the turbo, Eventuri designed a heat shield to protect the carbon tube. The shield is powder coated black but has a gold reflective layer on the base which deflects radiation heat from the turbo and catalyst. It has a stainless steel brace to provide rigidity and curves around the back of the tube to deflect convective heat away. Please note – this shield may not fit some full frame turbo systems with a different exhaust manifold. The Eventuri Difference 1) The sealed system keeps IATs low – the engine bay can get heat soaked very quickly so an open cone filter will cause an increase in IAT values resulting in a loss of performance. 2) The Venturi housing provides a smooth transition from the filter to the intake tubes which are both matched to an internal diameter of 103mm. This helps the hybrid and full frame turbo setups to run more efficiently. 3) The entire system is constructed from pure pre-preg carbon fibre which is great at insulating from heat and has smooth internal surfaces as opposed to fibreglass which will have sharp resin lines present. ABOUT EVENTURI: Eventuri was founded by a team of engineers and enthusiasts with a background in Aeronautics and tuning – all sharing a passion for cars and performance. Eventuri Intakes are extensively developed using cutting edge design, testing and prototyping methods. With a focus on performance, each design undergoes CFD analysis and is then validated at the prototype stage through volumetric airflow, intake temperature and extensive dynamometer testing. We strive to publish all the development information to illustrate the depths we go to in bringing an intake from concept to reality. After many years of disappointment with the usual aftermarket intakes, Eventuri are proud to be raising the bar and creating intake systems which are setting a new standard and genuinely improve performance.
