Eventuri Porsche 991 991.2 GT3 RS Black Carbon Intake System

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. You can read more about the housing design and how it works HERE

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 RS3 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.
