Eventuri BMW F9X M5/M8 Black Carbon intake met shrouds systeem

BMW F92 M8 / M5 F90

Acceleration Time : 60-130mph Reduced By 0.22 seconds
Max Flow Rate Per Airbox at 28″ H2O: Stock 620 CFM, Eventuri 736 CFM

The F92 M8 / M5 F90 Eventuri intake system was developed through extensive real world testing and airflow simulation analysis. It features sealed filter housings to maintain a steady IAT, even while stationary. The shrouds which seal the housings, coupled with our scoop and shield combination ensures unrestricted airflow whilst maintaining low IATs through cold air saturation. Our large front air scoops transfer ambient air directly into the intake area thus ensuring the engine doesn’t suffer from heat soak. In addition, our gold heat-reflective lined shields have integrated flow guides which direct the ambient air from the scoops into the filters. We have also managed to increase the inlet tube cross-sectional area by over 30% compared to the stock intake as it feeds through the openings in the strut braces. This allows the turbos to work more with less restriction and reduce the waste-gate duty cycles.

The Eventuri Difference

The F92 M8 / M5 F90 Eventuri system uses our Patented Carbon Fibre Housings with our Gen 2 bespoke filters, which provide an aerodynamically efficient airflow path from the filter to the turbos. Not just another cone filter with a heat shield but a unique design which invokes the Venturi affect and maintains laminar flow conditions to reduce the drag on the turbo.

The Eventuri F92 M8 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:

• 2 x Carbon Fiber Venturi Housings with Integrated Tubes
• 2 x Bespoke High Flow Generation 2 Filters
• 2 x Carbon Fiber Filter Shrouds
• 2 x Aluminium Inlet Cowls
• 2 x Carbon Fiber Air Scoops
• 2 x Laser Cut Heat Shields lined with Gold Heat Reflective Material
• 2 x Laser Cut Air Ramps integrated into the Heat Shields
• High Quality Silicon Couplers and OEM Spec Hose Clamps

The filter housings comprise of our bespoke generation 2 filters, aluminium inlet cowls, carbon shrouds, the carbon pods and integrated tubes. The carbon pods shroud the reverse mounted filters and smoothly shape the airflow down to the stock turbo inlet tubes. This is a key feature of the intake design where we have removed the requirement for a convoluted rubber hose between the airbox and the turbo inlet tubes. The filter housings and integrated tubes extend all the way to the stock turbo tubes and are able to move as one piece with the engine through the strut braces. This removes the extra interfaces of having a separate convoluted tube which the stock system requires for flexibility as the stock airboxes are mounted to the chassis so cannot move. The result is a smoother path from the filter to the turbo inlets and therefore the turbos are able to function with less drag. The diagram below summarises the differences between the stock airbox and the Eventuri F92 filter housing.

INTERNAL VOLUME

Another key design feature of the intake housings is the internal volumes of the tubing as they pass through the strut braces. On the F90 M5, the airbox system must pass through an oval opening in the strut brace on each side before reaching the turbo inlets. We have managed to increase the internal size of our intakes at this junction which results in more available volume for the turbos to draw from and therefore less restriction. The increase in cross sectional areas between the Eventuri and the stock airbox is 31% as follows:

• Internal Cross Sectional Area of intake tube at the strut brace:
• Stock Airbox Tube = 6487mm²
• Eventuri Intake Tube = 8497mm²

PATENTED TECHNOLOGY

Our patented filter housings have a smooth reduction in cross sectional area as they shroud the filters and taper down to the tubing. This geometry invokes the Venturi effect where the airflow accelerates whilst maintaining laminar conditions. It can be thought of as a large velocity stack - below is a diagram to show the comparison between our patented design and a regular intake system. Our bespoke filters aid the airflow moving through the housings and allow for an even velocity profile as the airflow exits the housings.
