The Porsche GT3 RS intake was developed to provide a more efficient flow path to the engine compared to the OEM airbox. By utilising our patented Venturi housing concept, the airflow can pass through the filters on a much less tortuous path, reducing the drag of the system. In addition, by increasing the total volume in the intake tract, the maximum flow capacity has also been increased. By using customised filters with an outer diameter of 192 mm or 7.5? and a filter surface area of over 110,000 mm^2 each, we have made optimum use of the available space. Intake air temperatures have also been minimised through a sealed system and the use of carbon fibre, which has a low coefficient of thermal conductivity across the wall thickness. The result is a real increase in performance and a noticeable improvement in throttle response.

The Eventuri difference
The 991 GT3 RS Eventuri system uses our patented carbon fibre housing, which provides an aerodynamically efficient airflow path from the filter to the engine.

Flow tests
We conducted flow tests using a Superflow SF-1020 to measure the maximum possible flow rate at a pressure drop of 28" H2O. The tests were performed on the same day under controlled conditions, using the same test fixture for each system. We tested our complete intake system compared to the stock airbox system. The results show an increase in maximum flow by an additional 120 CFM over the OEM airbox. Importantly, this was achieved with a sealed intake system so that intake temperatures are also kept to a minimum.

Bench test
Our GT3 RS intake was independently tested by ES Motors, who build high performance Porsches in the UK. The tests were carried out on a chassis dyno on the same day, one after the other. As you can see, there is a measurable gain across the rev range, not just at the peak, which is more important as the increased area under the graph shows that the intake has an impact beyond the headlines. This gain is noticeable even on a production car on the road through better throttle response and quicker acceleration. The first chart is the summary of the results and the second is a screenshot of the dyno test to show the gain in the mid-range.
