PERFORMANCE 

Flow Bench Testing

We conducted flow rate tests using a Superflow SF-1020 to measure the maximum flow rate possible at a pressure drop of 28” H2O. Tests were done on the same day in controlled conditions using the same test jig for each system. We tested our full intake system against the stock airbox system. The results show an increase of maximum flow by an additional 120 CFM over the OEM airbox. Importantly this has been achieved with a sealed intake system so the intake temperatures will also be maintained at a minimum.

Dyno Testing

Our Intake has been independently tested by ES Motors who build high powered Porsches in the UK. Tests were done on the same day back to back using a chassis dyno. As can be seen, there is a measurable gain throughout the RPM range, not just at peak which is more important as the increased area under the graph demonstrates that the intake is making an impact beyond the headline figures. This gain even on a stock car is noticeable on the road with better throttle response and quicker acceleration. The first graph is the summary of results and the second is a screenshot of the dyno test to show the gain in the mid-range.

PRODUCT DETAILS 

Part Numbers:

• EVE-GT3RS-INT : Porsche 991.1 991.2 GT3 RS

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

PATENTED FILTER HOUSING

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. Further details can be read in the Technology page.

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.

CARBON DUCTS

The ducts channels ambient air from the side vents to the filter housing. In order to ensure a good seal against engine bay heat – they are secured to the filter housing at 3 points and use a neoprene gasket for an airtight seal . The ducts were designed to have the maximum internal volume possible within the given geometry of the engine bay. This ensures that the filter housing is able to draw with minimum restriction.

SILICON COUPLER

Our silicon coupler replaces the stock flexible tube to the throttle body. It matches the OEM throttle body with an internal step to ensure smooth flow.

The complete system comes together to provide an intake which improves on the stock airbox in performance, aesthetics and sound………
