PORSCHE 991 GT3 RS

Performance Gain : 8-11hp, 8-10ft-lb
Flow Bench Data: Stock Intake 905 CFM : Eventuri Intake 1025 CFM
 

Fitment: 991.1 and 991.2 GT3 RS
 

The Porsche GT3 RS intake has been designed to offer a more efficient flow path to the engine in comparison to the OEM airbox. Utilising our Patented Venturi Housing concept, airflow is able to negotiate through the filters with a much less tortuous path thus reducing the drag of the system. Furthermore by increasing the overall volume in the intake, the maximum flow capacity has also been increased. Using bespoke filters with an outer diameter of 192mm or 7.5″ boasting a filtration surface area of over 110,000mm^2 each, we have made maximum use of the available space. Intake air temperatures have also been minimised by ensuring a sealed system as well as using carbon fiber which has a low thermal conductivity coefficient across the wall thickness. The resulting system provides genuine performance gains and a noticeable improvement in throttle response.
 

The Eventuri Difference

The 991 GT3 RS Eventuri system uses our Patented Carbon fiber Housings which provide an aerodynamically efficient airflow path from the filter to the engine. Not just another cone filter with a heat shield but a unique design which invokes the Venturi affect. 

The Eventuri 991 GT3 RS intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards. We use 100% pre-preg carbon fiber with no fibreglass which means we can achieve a smooth internal surface to maintain smoother airflow. Here are the details for each component and the design ethos behind them:

Each intake system consists of:
Carbon Fiber Double Venturi Filter Housing
Bespoke High Flow Dry Cone Filters
Carbon Fiber Inlet Ducts
Silicon Coupler Internally Stepped
Laser Cut Stainless Steel Brackets

The 991 GT3 RS Filter Housing comprises of 2 bespoke high flow filters, aluminium cowls, laser cut brackets and the carbon pod itself. The carbon pod shrouds the reverse mounted filters and smoothly shapes the airflow down to the throttle body. 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 patented design and a regular intake system. 

BESPOKE CONE FILTER
In order to achieve the highest flow rate possible we designed a filter element to make as much use of the space available in the engine bay as possible. This new filter has an outside diameter of 192mm or 7.6″ and when flow tested with a housing using a 4″ opening is able to flow up to 900 CFM at 28″ H2O. The filter medium is ISO tested to ensure that filtration is in line with OEM standards and is also dry. The filter is constructed with our signature flow cones to aid in the Venturi housing principle.
