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.
*Gains measured can vary with different ECU tunes.

LOWER AIRBOX

We have completely redesigned the entire airbox system including the base which the filter sits inside. We have combined the slam panel with the lower airbox and increased the volume of this area to help increase the total flow rate. Furthermore, the base has been designed to allow the filter to sit at a more favourable angle to the turbo inlets. Where the stock airbox has a 90 degrees turn from the filter to the inlets, our airbox has a less abrupt angle and this allows for a smoother flow path.

AIRBOX LID

During development we designed and tested 4 different designs for the lid and test results showed that V2 was the highest performing. This design was optimised with CFD simulations and provides a smooth flow path from the filter to the inlets. Our design has an increased volume in comparison to the stock lid and is more organically shaped with smoother curves as opposed to the stock lid which is very cuboid. Furthermore the openings to the turbo inlets have been significantly increased in size.

TURBO INLETS

The inlets have been increased in size at the airbox side by as much as 85% more than the stock inlets and smoothly taper down to the stock turbos. This increased size significantly reduces the drag in the turbos and therefore allows them to work more efficiently. We have also incorporated CNC machined bushes and rings in the inlets for structural strength. For cars with hybrid turbos, we also have separate inlets available on request to match the different inlet diameters.

BESPOKE BMC FILTER

Our airbox required a bespoke panel filter and for this we collaborated with BMC who have developed their iconic filter specifically for our system. It is a washable 4-layer cotton mesh filter which provides superior filtration while maintaining a low pressure drop.

The complete intake system comes together to provide a superior airbox which allows the turbos to reach target boost levels much sooner and therefore the engine is able to produce more power earlier in the RPM range. When combined with a tune where the boost levels are increased, our airbox provides the required de-restricted flow path for the turbos to achieve elevated boost pressures.
