Plenum for Porsche 992 Turbo and Carrera. Improved response across the entire power range!
Background
When the 992 generation was launched, Porsche abandoned the naturally aspirated engine for the Carrera models. From now on, all 911s will be turbocharged! There are some differences between the Carrera and Turbo models, the displacement being the most obvious, but they also share many components: the plenum is one of them! Throughout the entire development of the 992 products, we had unrestricted internal access to a 992. We always work this way. It allows us to test our theories, prototypes, and 3D prints without obstacles or delays. We like to think this is visible in the finished product, refined without compromise. We are confident in what we have to offer the market!
Development
Starting with a complete 3D scan of the engine compartment to identify structural limitations, we got to work. With experience gained with previous Porsche plenums, we quickly realized the need for a Y-joint rather than the OE T-shaped plenum. From an airflow perspective, the Y-shape is more efficient as it distributes air more evenly and with less pressure drop. We chose, as usual, to make the plenum from cast aluminum because it allows for shapes that CNC machining cannot replicate, and for us, function always trumps form. Maximum airflow trumps bling!
The do88 plenum
The plenum is designed with smooth, sweeping lines. Radii and corners have been revised and reworked several times. The connections are CNC-machined, and the plenum comes with silicone tubing for optimal fit and durability. The improved airflow is verified using CFD (Computer Flow Dynamics) and on our Superflow SF1020 flow bench. Eliminating restrictions for turbocharged air reaching the intake will provide improved throttle response and performance improvements throughout the powerband!
Key Figures
– More air to your engine, less backpressure, and improved airflow!
– Air flow at 0.1 bar / 1.45 psi pressure drop: 846 CFM (808 CFM), 5% more!
– Freeform cast aluminum design with CNC-machined connections.
– Y-design for optimal air distribution.
– Comes with all necessary installation hardware.
