Eventuri Carbon Fibre Intake System for BMW M5/M8 F9x S63

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

The F90 M5 Eventuri intake system was developed through extensive real world testing and airflow simulation analysis. Now in the updated V2 design, it features sealed filter housings to maintain a more steady IAT, even while stationary. The new 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 F90 M5 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 intake was tested on the road using a Vbox unit to record the acceleration from 60-130mph . Testing was carried out on the same stretch of road – again on the same day to keep variables minimum. Results show that with just the intake added – on stock software, the acceleration times from 60-130mph reduced by 0.22 seconds which is a significant improvement at such speeds.

Acceleration results summary:

• 60-130mph with Stock intake = 8.48 seconds
• 60-130mph with Eventuri intake = 8.26 seconds

The gains are from a combination of reasons:

1) The larger inlet tube volume alows the turbos to work with less drag.

2) The Venturi housings provide a smooth transition from the filter to the intake tube keeping airflow laminar.

3) The large front scoops force ambient air into the intakes keeping the IATs low.
