Eventuri carbon intake system for Porsche 991 GT3 RS

Eventuri carbon intake for Porsche 991.1/2 GT3 RS

2019 Porsche 911 Carrera S

Power increase: 8-11hp, 8-10ft-lb

Flow Bench Data: Stock Intake 905 CFM : Eventuri Intake 1025 CFM

Suitable for: 991.1 and 991.2 GT3 RS

The Porsche GT3 RS intake has been designed to provide a more efficient flow path to the engine compared to the OEM airbox. By using our patented Venturi housing concept, the airflow can pass through the filters in 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 bespoke filters with an outside diameter of 192mm or 7.5? and a filter area of ​​over 110,000 mm^2 each, we have made the most of the available space. Intake air temperatures have also been minimised by a sealed system and the use of carbon fibre, which has a low thermal conductivity coefficient across the wall thickness. The result is a real gain in power and a noticeable improvement in throttle response.

The Eventuri Difference

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

Flow tests

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

Bench test

Our RS3 intake has been independently tested by ES Motors who build high performance Porsches in the UK. The tests were carried out one after the other on a chassis dyno on the same day. As you can see there is a measurable gain across the entire rev range, not just at the top, 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 in a production car on the road through better throttle response and quicker acceleration. The first graph is the summary of the results and the second is a screenshot of the dyno test to show the gain in the mid-range rev range.
