Eventuri carbon intake system for Porsche 991.1/991.2 GT3 RS

Eventuri carbon intake for Porsche 991.1/2 GT3 RS

PORSCHE 991 GT3 RS
Power Increase: 8-11hp, 8-10ft-lb
Flow Bench Specifications: Stock Aspiration 905 CFM : Eventuri Aspiration 1025 CFM

Suitable for: 991.1 and 991.2 GT3 RS

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

The Eventuri difference

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

flow tests

We performed 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 have ours Complete intake system tested versus stock airbox system. Results show an increase in maximum flow of an additional 120 CFM over the OEM airbox. Importantly, this was achieved with a sealed intake system so intake temperatures are also kept to a minimum.

dyno test

Our RS3 intake has been independently tested by ES Motors who build high performance Porsches in the UK. The tests were carried out consecutively on a chassis dyno on the same day. As can be seen there is a measurable gain throughout the rev range, not just at top, which is more important as the increased area under the graph shows that induction has an impact beyond the headlines. This gain is noticeable even in a production vehicle on the road through better throttle response and faster acceleration. The first graph is the summary of the results and the second is a screenshot of the dyno test to show the mid-range gain.
