We are proud to present our newly developed Plenum for Porsche 991.2 Carrera, -S, -GTS.
More response over the entire powerband!

Background

The OEM 997.2 Turbo plenum is T-shaped which means the air flow from the throttle body abruptly change direction when it´s divided to each side of the intake manifolds. It makes sense to design a plenum with a Y-shape instead of a “bank into the wall”; T-shape!

Development

With the starting point in a comprehensive 3D-scan of the engine bay to get the structural limitations, we set to work. With the experience we had from previous Porsche plenums, we soon realized the need for a y-joint rather than the t-shaped OE plenum. From an airflow perspective the y-shape is more efficient as it distributes the air more evenly and with less pressure drop. We chose, as usual, to manufacture the plenum from cast aluminum as it allows for shapes that CNC-machining cannot replicate, and to us function always conquers form. Maximum airflow supersedes the bling factor!

The do88 plenum

The plenum is designed with soft, sweeping lines. Radiuses and angles have been revised and reworked many times over. The connections are CNC-machined and the plenum comes with suiting silicone hoses for optimum fitment and durability. The improvement in airflow is verified using CFD (Computer Flow Dynamics) as well as in our Superflow SF1020 flow bench.

Taking away restrictions for the turbocharged air that reaches the inlet will provide better throttle response and performance gains all over the powerband!

Key figures

• More air to your engine, less backpressure and better airflow! Airflow at 0,1 bar / 1,45 psi pressure drop: 846 CFM (808 CFM), 5% higher! See diagram below.
• Freeform designed, aluminum casting with CNC-machined connections.
• Y-design for optimum air distribution.
• Comes with all accessories needed for installation.
