SKU: EV.AUD.RSXC8.S
The Audi C8 RS6 intake system is the culmination of extensive development, testing and prototyping. Our 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. Our 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 we 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, our intake minimises the formation of turbulence and therefore the turbos are able to operate more efficiently. We 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, our 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 we have developed from the airbox base to the lid and the inlets. DYNO TESTINGOur intake has been independently tested both on the dyno and on the road. With higher states of tune the turbos demand more air and therefore the stock airbox becomes a bigger restriction. Here are some results from respected tuners who have tested the intake.STOCK ECU TESTINGDyno testing was carried out by Awesome GTI in the UK on their own C8 RS6 equipped with an aftermarket OPF back exhaust. They tested the car with the stock map and also their own stage 1 remap. They ran the car 4 times in 4th gear with the stock airbox and then swapped over to the Eventuri while the car remained on the dyno. The car was then run again in 4th gear 4 times. Testing was all done on the same day and no other changes were made. The graph below shows the highest power from the stock airbox vs highest power run from the Eventuri intake. Both were the first dyno pulls with subsequent pulls reducing in power due to heat soak. As can be seen below the intake provides a significant gain in performance throughout the RPM range with the stock map and more so with the stage 1 remap. The highlighted point shows the highest gain in the RPM range of 23hp at the wheels.
