Eventuri Porsche 991 Turbo Carbon Intake System | Cicio Performance

Eventuri Porsche 991 Turbo Carbon Intake System

Acceleration results summary:

• 60-130mph with Stock intake = 8.04 seconds
• 60-130mph with Eventuri intake = 7.83 seconds

The gains are from a combination of reasons:

1) Individual Venturi Housings separate the flow path for each turbo allowing them to work more efficiently.

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

3) Intake air temperatures are kept to a minimum by ensuring a sealed system to prevent pulling in heated engine bay air.

The Eventuri 991 Turbo 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 Aluminium Inlet Cowls
• Carbon Fiber inlet duct
• Laser Cut Stainless Steel bracket work

INTAKE HOUSING ASSEMBLY

The filter housings comprise of our bespoke generation 2 filters, aluminium inlet cowls, 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. By separating the inlet path and having a dedicated filter for each turbo, the intake allows the turbos to function more efficiently. Crucially, the Venturi housings organically extend with a smooth curve from the filter opening to the stock turbo tubing. This ensures that the airflow remains as smooth as possible throughout the system. Smooth airflow results in less drag and therefore the turbos can reach peak boost sooner in the RPM range. It also means that the throttle response feels sharper.

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. Further details can be read in the Technology and Filters pages.

INTAKE DUCT

The intake duct seals against the underside of the boot-lid using the stock rubber cushion and then extends down to seal against the filter housings. Crafted from 100% prepreg carbon fiber the intake duct ensures that the intake pulls in ambient air only and not heated engine bay air. Again in order to maximise flow efficiency the transition from the circular openings for the filter housings to the single air entry point is as smooth as possible. The duct also features 2 drain tubes which direct water away from the filters. The tubes are designed such that the intakes will draw a minimum amount of air from within the engine bay due to the larger flow resistance in the tubes as compared to the opening at the top of the duct. The complex geometry of the duct was necessary to clear the various components in the engine bay of the 991 Turbo.

BRACKET WORK

The brackets are laser cut from stainless steel and powder coated. We went to great lengths to ensure that the intakes have a precision fitment using the stock airbox mounting locations. The brackets not only brace the intakes to the chassis but also allow engine components to be secured as they are with the stock airbox. In order to save weight, each bracket has purposely shaped cutouts which remove material yet allow the overall structure to remain rigid.

The complete system comes together to provide an audible and noticeable performance improvement over the stock airbox system.
