The Audi C8 RS6 intake system is the culmination of extensive development, testing and prototyping. Eventuri aim was to address 2 main criteria: 1) Increased flow rate. 2) Smooth Airflow. The first objective was met by utilising all of the limited space available in the RS6 engine bay which was heavily restricted by the underside of the hood. Eventuri solution was to completely redesign the entire airbox which maximised volume, increased flow entry openings and created a more favourable filter angle to the turbos. Furthermore Eventuri dramatically increased the size of the turbo inlets by as much as 85% when measuring the cross sectional area at the openings. The second objective was met by designing an organically shaped system with a custom rounded panel filter to ensure the airflow path contained no sharp corners and therefore allowed for the flow to remain laminar. With smooth transitions from the filter to the turbo inlets, Eventuri intake minimises the formation of turbulence and therefore the turbos are able to operate more efficiently. Eventuri partnered with BMC for a bespoke filter element to ensure that the filtration area is as large as possible whilst keeping airflow clean.
With all objectives met, Eventuri C8 RS6 intake system delivers on all fronts and allows for the turbos to generate boost more efficiently. This results in an improved throttle response and significant power gains, independently tested which increase with higher states of tune. The performance gains measured are a result of the complete system Eventuri have developed from the airbox base to the lid and the inlets.
