Facts: Performance increase stock map: 14-20hp, 17-21ft-lb Performance increase level 1 map*: 25-28hp, 20-23ft-lb Material: Carbon Manufacturer: Eventuri Expert opinion: withoutOur 4.0TFSI V8 EA825 intake system was developed from scratch and the entire air intake duct was optimised. Every component, including the cover, has been designed to allow the twin-turbo V8s to draw in air with less drag, resulting in industry-leading performance gains. The standard airbox lid itself restricts the size of the flow collector that feeds the filter inlets. Therefore, we have increased the height of the centre section of the lid to allow a larger flow collector and larger cone filters to be used. This removes the inherent restriction and sets our intake apart from the rest of the field, which also has to use a restricted header and filter media by using the standard lid. The turbo inlets are up to 43% larger in cross section than the standard inlets and feature an advanced dimpled inner surface to reduce frictional losses between the flow and the wall boundary. By creating an air "cushion" on the wall surface, the airflow can move through the inlets at higher flow rates and lower pressure drop. This allows the turbos to draw in air with less resistance, reducing the wastegate duty cycle, resulting in higher overall performance. *Measured gains may vary with different ECU setups. Bench test This intake was independently dyno tested by Eurocharged Canada. Testing was conducted back to back with the stock airbox and multiple runs were made with each configuration. The dyno results show a consistent power increase across the rev range, which is due to the turbos reaching maximum boost pressure earlier and a lower wastegate duty cycle being required due to the higher efficiency of the intake system. The first diagram shows the results of a vehicle where only the intake has been changed between runs. The second diagram shows an RSQ8 that was run with a stage 1 set-up and a drop-in filter as the base vehicle. The intake was then changed, while the set-up remained unchanged. The increase in performance on both cars can be seen on the road in improved response at part and full throttle, with the car pulling much more eagerly to redline.
