Porsche has been controlling engine output by restricting the inlet track for decades. This has been successfully accomplished by utilizing smaller throttle bodies. This simple power control solution has been a very effective way of preventing lower level models from out performing certain flagship models, especially models with prolific racing pedigree. Although the factory engine packages are fantastic performance machines, they are engineered and developed to achieve specific performance numbers that satisfy a target demographic and compete with rival brands. Unfortunately driving enthusiasts who seek an elevated Porsche driving experience require performance levels well outside the target market.
All of the IPD Plenums deliver substantial power and torque gains, but when combined with larger throttle bodies they perform even better. All of the IPD "Competition" Plenums utilize the next largest size throttle body offered by Porsche. In this case, the Competition Carrera upgrades the factory OE 74mm throttle body with Porsche's 82mm 997 GT3 throttle body. All of our Competition Plenums are designed to perform with cars equipped with high performance exhaust systems. The more extensive the exhaust system (headers, kats and mufflers) the better. Optimizing air intake and exhaust together creates a balanced performance package that allows the engine to inhale and exhale more air thus creating more power and torque.
IPD has pioneered another new Plenum design with the Competition Carrera Plenum. Laminar flows and volumetric efficiencies have been further enhanced with our unique and innovative internal merge collector area. This completely new approach has yielded not only great performance gains but more linear power delivery and improved throttle response as well. Gains vary depending on pre-existing mods and quality of after-market exhaust installed. As we all "should" know, horsepower and torque become harder to find and typically more expensive as we climb the proverbial performance ladder. That being said, performance components yield different power gains depending on the order they were installed. IPD tests and evaluates all products on bone stock cars, this establishes a level playing field and a better "apples to apples" comparison. The Competition Carrera Plenum however is designed to work with applications that are already moderately to heavily modified. Power gains will vary with each Carrera, but the bottom line is, there will be noticeable and impressive gains that are sure to make any Porsche Carrera driving enthusiast smile.
Power improvements will be fully realized once the factory ECU/DME makes all the necessary "adaptation" requirements. This process can be expedited with a series of "hard pulls" or spirited full throttle acceleration runs through the gears. Of course this should only be performed on a closed course circuit.

The 992 Turbo engine is another modern marvel from Porsche. We were fortunate enough to have unlimited access to a 992 during our extensive development and testing program. This unrestricted time frame proved to be invaluable, allowing IPD to scrutinize every engineering and design aspect in an effort to deliver the best performing Plenum possible.
Like all previous IPD Turbo Plenums, the 992 Plenum is a product of efficiency that produces substantial HP and TQ gains through a superior and patented "Y" design that manages and delivers optimized air flow for enhanced engine performance. The Plenum has been proven to produce substantial net gains across both power bands and is guaranteed to elevate the driving experience of any Turbo.
Development started with a 1D simulation to optimize the treatment of pulse peaks in the intake tract using different pipe geometry and known engine parameters of the 992. We then graduated to optimizing 2D slices of the plenum in CFD, paying special attention to places where adverse pressure gradients that might cause separation. This allowed us to adjust curvatures on the plenum faces and build up our understanding of what was happening inside the pipe at full throttle.
After we were pleased with the 2D slices we graduated to 3D adding in all the geometry to make this a plug and play bolt-on part with optimal performance characteristics. After hundreds of geometrical and CFD iterations, we were pleased with not-only the increase in mass flow compared to the stock intake, but also the uniformity of the charge pressure and velocity across the 2 branches.
The efficiencies of the Plenum dramatically reduce initial turbo lag down low helping access the power and torque sooner, but the bulk of the power and torque gains are realized from 4000 rpm to redline, where we need and enjoy it most. The HP and TQ gains continue to increase and out-perform the factory air distributor as you climb through the revs. Peak gains of 35+ wheel HP and 35+ wheel TQ are achieved above 6000 rpm. The 992 Turbo Plenum delivers very impressive power and torque gains that will raise the performance bar of the already potent Turbo as well as raise the hairs on the back of your neck.

About the Performace Plenum:
Background:
Upon launching the 992 generation, Porsche had abandoned the naturally aspirated engine for the Carrera models. From now on, all 911´s are turbocharged! There are a few differences in between the Carrera and the Turbo models, the displacement being the most obvious, but they also share a lot of components – the plenum is one of these! Throughout the entire development of the 992 products, we had unlimited in-house access to a 992. This way of procedure is how we always do it. It allows us to test our theories, prototypes and 3D-prints without hurdles or delays. We´d like to think that this shows on the finished product – ultimately refined without compromise. We are confident with what we have to offer the market!
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 realised 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 aluminium 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 power band!
Key figures:
- More air to your engine, less back pressure and better airflow!
- Airflow at 0,1 bar / 1,45 psi pressure drop: 846 CFM (808 CFM), 5% higher! See diagram below.
- Freeform designed, aluminium casting with CNC-machined connections.
- Y-design for optimum air distribution.
- Comes with all accessories needed for installation.
