air line Genuine Porsche part 9A211009801

Performance inlet plenum.



To Fit:
Porsche 997 Turbo and Turbo S from 2010-2012

do88 are proud to present our newly developed Inlet Plenum for the Porsche 991 Turbo and Turbo S

With this high flow Plenum, the performance of your 991 will increase!

• do88 plenum is Y-shaped for improved air flow. • Our plenum flows 5,4% better compared with the OEM plenum (IPD aftermarket 2,1%) (see graph image)
• High quality casting pipe with CNC-machined connections
• Smooth internal surface for best air flow
• Comes with all necessary accessories for installation.

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" flat T-shape. During the development process of this plenum we spent a lot of time with flow simulations of the internal Y-shape design. We made both flow simulations on our CAD system and real tests on our own SuperFlow SF-1020 flow bench using 3D-printed models.

To be able to manufacture this final design we choose to make a 3D freeform designed casting. This construction adds a lot of performance but not so much of extra weight. We designed the outside of the plenum to add as little weight as possible to the plenum.

do88 Performance Plenum weight 0,66 kg (1,46 lb) OEM plastic pipe weight 0,27 kg (0,60 lb) and competitor cast performance pipe (IPD) weight 1,13kg (2,49 lb)!

Be aware that the OEM parts were designed for the power level the car was built for originally. A power increase may cause your stock plenum to hold back the power of your engine. So even on an engine with a software tune only the do88 performance plenum will give a performance increase!

do88 performance plenum comes as a complete package with all parts necessary for installation.

Aluminum intake plenum, 74mm IPD Plenum ('20-Current).



Fits:
Porsche 992.1 Turbo / Turbo S 3.7L

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.
