Eventuri Gloss Carbon Fiber Intake System for C8 Audi RS6 and RS7

Eventuri Gloss Carbon Fiber Intake System for C8 Audi RS6 and RS7

The Audi C8 RS6 intake system is the culmination of extensive development, testing and prototyping. Eventuri’s aim was to address 2 main criteria: 1) Increased flow rate. 2) Smooth Airflow. The first objective was met by utilizing all of the limited space available in the RS6 engine bay which was heavily restricted by the underside of the hood. Their solution was to completely redesign the entire airbox which maximized volume, increased flow entry openings and created a more favorable filter angle to the turbos. Furthermore they 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, the intake minimizes 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, their 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 they have developed from the airbox base to the lid and the inlets.

Lower Airbox

• They have completely redesigned the entire airbox system including the base which the filter sits inside. Eventuri has 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 favorable angle to the turbo inlets. Where the stock airbox has a 90 degrees turn from the filter to the inlets, the airbox has a less abrupt angle and this allows for a smoother flow path.

Airbox Lid

• During development they designed and tested 4 different designs for the lid and test results showed that V2 was the highest performing. This design was optimized with CFD simulations and provides a smooth flow path from the filter to the inlets. The 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. Eventuri has also incorporated CNC machined bushes and rings in the inlets for structural strength. For cars with hybrid turbos, they also have separate inlets available on request to match the different inlet diameters.

Bespoke BMC Filter

• Their airbox required a bespoke panel filter and for this they collaborated with BMC who have developed their iconic filter specifically for Eventuri’s 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, the airbox provides the required de-restricted flow path for the turbos to achieve elevated boost pressures.

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. After owning various intakes over many years for their own cars and being disappointed with the gains which seldom lived up to their claims – they decided to take things into our own hands and rewrite the book. To set a new benchmark in intake design and technology, above all – to engineer systems which provide real gains and then to publish genuine figures.

Their systems 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. They strive to publish all the development information to illustrate the depths they go to in bringing an intake from concept to reality.

Only the best materials are selected for each component – even down to the choice of fasteners and fixings in order to ensure that the quality of the end product is second to none.

After many years of disappointment with the usual aftermarket intakes, they are proud to be raising the bar and creating intake systems which are setting a new standard and genuinely improve the performance of your vehicle.
