Eventuri – E39 M5 Black Carbon Intake

Performance Gain: 8-12hp, 8-10ft-lb

The BMW E39 M5 Eventuri intake is designed to offer a complete solution as an upgrade to the stock airbox system. Our aim was to develop an intake system for the S62 engine which worked with the stock ECU map and MAF sensors and produced a genuine improvement in the driving experience. With Our Patent Pending Venturi housing, we have ensured that the airflow remains as laminar as possible. Furthermore, the addition of a true cold air feed by adding scoops integrated with the front fog lamps results in the lowest possible inlet air temperature. This leads to an optimised intake system which delivers noticeable performance gains consistently.

The Eventuri Difference

The E39 M5 Eventuri system uses our Patent Pending Carbon fibre Housings with our bespoke Gen-2 filter which provide an aerodynamically efficient airflow path from the filter to the inlet tubes. Not just another cone filter with a heat shield but a unique design which invokes the Venturi affect. You can read more about the housing design and how it works HERE

EVE-E39-INT : BMW E39 M5 Black Carbon intake

The Eventuri E39 M5 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 Carbon Fibre Venturi housings
• 2 High Flow generation 2 Air Filters
• 2 Aluminium Cowls for smooth airflow entry
• 2 Foglamp surrounds with integrated air ducts
• 2 Flexible Neoprene air ducting sections
• 2 Laser Cut Aluminium Shields
• Laser Cut Custom Brackets
• High quality Silicon couplers with BMW specification hose clamps

Carbon Intake Housing Assemblies

The filter housings comprise of the high flow filters, aluminium cowls and the carbon pods themselves. The carbon pods shroud the reverse mounted filter and smoothly shape the airflow down to the MAF tubes. This smooth reduction in cross sectional area 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 patent pending 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. Further details can be read in the Technology and Filters pages.

Foglamp Ducts

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.

Performance

The standard airbox draws in air from behind the front bumper so the flow path is long and this introduces drag in the system. Furthermore the cuboid nature of the airboxes give rise to turbulence where the transition to the circular MAF tubes take place. Our system replaces the airboxes with Venturi housings which transition much more efficiently to the circular MAF tubes maintaining laminar flow. The filters draw air from a shielded part of the engine bay which is saturated with cold air from the integrated foglamp scoops. By keeping inlet temperatures low and improving the flow path efficiency, the engine is able to produce more power. The dyno graph below shows the comparison between the stock airbox and the Eventuri intake system on a standard car with standard map and exhaust. Dyno runs were done back to back on the same day and with the hood closed.
