Performance Plenum

Aluminum Intake Plenum High Flow Y Pipe.



Fits:
Porsche 991 GT2 RS

The new IPD Y-Pipe delivers the same amazing proven performance as with the previous generation Turbo. Porsche made very few changes to the intake system from the 991 Turbo to the 991.2 Turbo. Ballistic acceleration and a top speed of over 200 mph places the new Turbo in a very elite class of supercars. But of course the IPD Y-Pipe (and Plenum) raise the performance bar even higher for Porsche driving enthusiasts who seek fighter jet performance from their German Turbo missiles.

IPD invested countless hours of R & D with a variety of unique design features and multiple prototype tests before settling on an optimum design that significantly improves engine performance for both stock and highly modified 991 Turbos. Our innovative Y-Pipe design is not only larger but also utilizes "non-round" runners, an optimized merge collector area and our proven dimpled interior surfacing. This superior design delivers greater volume of air, improved laminar flow and increased air velocity. These improvements deliver an additional 40+ wheel HP, 50+ Foot Pounds of Torque, improved boost response and more linear power and torque curves.
As we all know, bigger is not always better when it comes to forced induction applications. The IPD Y-Pipe is considerably larger than the factory but not so large as to cause pressure drop within the intake tract resulting in turbo lag and reduced performance. This optimized "non-round" design with dimpled interior surface cannot be achieved with conventional round tube construction.

The Y-Pipe is a direct bolt-on engine upgrade that requires no modifications but should be perform by an experienced Porsche technician familiar with the 991 platform. Y-Pipes comes with all the required hardware necessary to complete the installation.

IPD Aluminium Intake Plenum. 74mm.



Fits:
Porsche 991.2 Turbo /S
Porsche GT2 RS

IPD took delivery of its 991.2 Turbo S and the R & D started the second it arrived at its new home. The new Turbo doesn't substantially benefit from any one particular upgrade, but the sum of its improvements deliver a superior overall Turbo compared to the already impressive 991.1 Turbo it replaces. Yes, we know the latest Turbo is faster with 20 more horsepower but it's the combination of lightening shifts, razor sharp handling and spiritual connection to the vehicle that elevates the driving experience of the extraordinary new 991.2 Turbo.

Porsche made a number of substantial upgrades with the latest 991.2 Turbo. Engine improvements include revised intake ports, larger injectors, higher volume fuel pump, larger turbo compressor wheels and more efficient intercoolers, but the factory intake system remained relatively unchanged allowing the IPD Plenum and Y-Pipe to fit with only minor modifications.

The 991.2 Turbo Plenum upgrade delivers staggering engine power and torque gains that will raise the performance bar of the already potent supercar as well as the hairs on your neck. Horsepower gains are found throughout the entire power band with the bulk of the gains being realized between the 3500-5000 RPM range. Max power gains of 45+ wheel HP come in at 4300 RPM and hold strong all the way to redline. Torque is even more impressive at 60+ in the midrange with a massive torque gains from 3500-5000 RPM.

Aluminum Turbo IPD Plenum.



Fits:
Porsche 991.2 Carrera /S / 4S / GTS

The new 991.2 turbocharged Carrera Plenums are now available for new Carrera drivers looking to raise the performance bar of their 3.0L turbo engines. The Carrera Plenum is very similar to the Turbo Plenum with only minor modifications to the hardware package. No official testing has been conducted as of yet but based on past experience and customer feedback we expect power gains to be in the mid 30+ range and torque over 40. Stay tuned for dyno testing coming as soon as we get our hands on a test car.

do88 Performance inlet plenum.



To fit:
Porsche 991 Turbo and Turbo S from 2013 onwards

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 991 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.

Equivalent Porsche part numbers 9A111003770, 9A211003702, 9A211013702 (for cross reference only).

In fuel injected engines, the throttle body is the part of the air intake system that controls the amount of air flowing into the engine, in response to driver accelerator pedal input in the main. The throttle body is usually located between the air filter box and the intake manifold, and it is usually attached to, or near, the mass airflow sensor.

The largest piece inside the throttle body is the throttle plate, which is a butterfly valve that regulates the airflow. Have a larger diameter throttle body produces more air flow with equals more power. The upgrades should be used in conjunction with the competition plenums.
