AUDI C7 RS6/RS7
Performance Gain: 15-19hp, 13-17ft-lb
V-Box Acceleration : 60-130mph Reduced By 0.4 Seconds
The Audi C7 RS6/RS7 Eventuri intake sets a new benchmark for intake design on this platform. It was developed to achieve two objectives – 1) De-restrict the turbo inlet paths. 2) Maintain low inlet temperatures. The first objective was met by providing each turbo with a separate filter and Venturi stack in order to reduce drag and allow the turbos to work more efficiently. The second objective was met by enclosing the filters inside a carbon airbox and feeding them with an additional scoop added behind the front grill. The C7 RS6/RS7 engine bay has multiple heat sources from different directions so a simple configuration of open filters and shields would result in higher IAT values. Our carbon airbox enclosure has been designed to maximise the use of the available volume and block all sources of heat. The resulting performance gains and aesthetics are industry leading for the C7 RS6/RS7.
The Eventuri Difference
The C7 RS6/RS7 Eventuri system uses 2 Venturi stacks mounted to the filters which smoothly transition to the turbo tubes. These provide an aerodynamically efficient airflow path from the filters to the turbos. Not just another cone filter with a heat shield but a unique design which invokes the Venturi affect and allows laminar flow to be maintained throughout the tubing, reducing the drag on the turbos.
The Eventuri C7 RS6/RS7 intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards. Here are the details for each component and the design ethos behind them:
Each intake system consists of:
- Carbon Fibre Airbox Enclosure
- 2 x High Flow Double Cone Air Filters
- 2 x Carbon Venturi stacks with integrated tubes
- Carbon Fibre Inlet Duct
- Carbon Fibre Front Scoop
- Laser Cut Heat Shield with Gold Reflective
- Laser Cut Stainless Steel Bracket Work
- CNC Machined Airbox Mounts
Carbon Airbox Enclosure
The enclosure has been designed to make the most effective use of the volume given when removing the OEM airbox. It shields the filters from the multiple sources of heat in the engine bay. The most obvious source is the engine itself however there is also a heat exchanger under the headlamp on the other side of the engine bay which also emits significant heat. Furthermore, when the radiator fan is operating, a stream of hot air is pushed into the intake area from the radiator. All these heat sources require a complete airbox system as shielding - a simple cone and heat shield just cannot do the same job. The airbox is connected to the carbon duct which feeds the enclosure with cold air.
Carbon Air Duct
We redesigned the inlet duct to have a larger internal volume than the stock version. This duct feeds the airbox enclosure with ambient air from the front grill to ensure inlet temperatures are kept as low as possible.
Carbon Air Scoop
The Air scoop sits behind the front grill and forces ambient air into the duct - the curved nature of the scoop ensures that the airflow is guided as efficiently as possible while the vehicle is in motion.
