The 991 Turbo Eventuri intake system was developed through extensive real-world testing with the goal of allowing the turbos to operate more efficiently. By replacing the single stock airbox with patented individual Venturi filter housings, the turbos are able to spool and generate boost with less resistance. As a result, wastegate duty cycles are reduced, resulting in increased peak power at lower rpm and therefore increased performance. The two individual filters provide a larger filtration area than a single-material panel filter. Additionally, to maintain low intake air temperatures, the Venturi housings are sealed against an air duct that extracts ambient air from the same location as the storage system. Because the 911 Turbo engine compartment is densely packed, high IATs can only be avoided by ensuring a completely sealed intake system. The combination of a smoother airflow path to each turbo with lower BASS results in higher performance and sharper throttle response over the stock airbox.
The Eventuri Difference
The Eventuri 911 Turbo system uses our patented carbon fiber housings with our custom-built Gen 2 filters, which provide an aerodynamically efficient airflow path from the filter to the turbos. Not just another cone filter with a heat shield, but a unique design that mimics the Venturi effect and maintains laminar flow conditions to reduce drag on the turbo.
The Eventuri 991 Turbo intake system is made up of a series of components designed for a specific purpose and manufactured to the highest standards. Here are the details for each component and the design ethic behind them: Each intake system consists of:
2 carbon fiber venturi housings with integrated tubes
2 custom-made high-flow filters
2 aluminum inlet cowls
Carbon fiber inlet duct
Laser-cut stainless steel bracket work
