Performance Plenum

The incredible 997 Porsche Turbo is the most revolutionary and capable Porsche Turbo to ever come out of Germany. The already explosive power can be further increased with the new 997 Turbo IPD Intake Plenums.



The patented IPD Plenum design works exceptionally well with all forced induction applications and the 997 Turbo is no exception. Power and torque increases provided by the IPD plenum are impressive and stay over and above all factory power curves from launch to redline. Maximum power increases take place in the midrange where it's most needed and most critical.

Maximum horsepower gains range from 30 to 35 depending on vehicle condition and pre-existing mods. The 997 Turbo plenums deliver smooth and linear power with considerably quicker boost response creating a longer and more desirable power band. The Turbo plenums deliver reliable performance for both street and motorsport applications enhancing the already visceral Porsche Turbo driving experience.

Unlike the 996 Turbo the 997 Turbo requires an "adaptation" period that can be fully realized with either a series of hard pulls on the dyno or 10 to 50 miles of hard driving which of course IPD recommends only be performed on a closed circuit race track.

The 997 Turbo has an extremely sensitive ECU/DME making it prone to external environmental corrections so it is imperative that proper, adequate and consistent cooling be available when you dyno any of the 997 Turbos to get accurate and reliable dyno figures both before and after each test.

Installation of all Turbo Plenums is highly recommended to be performed by qualified and trained Porsche technicians.

Turbo customers looking to increase engine power without pushing the motorsport envelope to redline would best benefit from the 74mm IPD Turbo Plenum.

This version of the 997 Turbo plenum utilizes the factory 74mm throttle body and delivers impressive performance gains for both stock and slightly modified Turbos with exhaust and software.

The 74mm IPD Turbo Plenum is also designed to perform with the higher flowing IPD "Y" Pipe.

The revolutionary 997 Turbo IPD "Y" Pipe was built for the more demanding Turbo performance customer. This is not a cast reproduction of the factory Y pipe but a complete re-design from scratch, developed to deliver even greater air flow for both stock AND highly modified Turbos.



The factory Y pipe becomes restrictive when adding substantial power gains. The IPD "Y" Pipe has larger inlets and an optimized diversion area allowing for even greater power gains. This superior and more efficient design flows 126 more cfm than the factory Y pipe delivering the additional power needed to raise the performance bar on any Turbo.

Bigger isn't always better, and the IPD "Y" Pipe is designed to deliver optimum flow without being too large causing a loss in boost response. These "Y" Pipes can also be special ordered in custom powder coated colors and ceramic coatings or polished to improve the aesthetic appeal of your Turbo engine.

The IPD 997 Turbo Y Pipe is designed to be a direct replacement of the factory OEM Y Pipe. There are no modifications or fabrication required for installing the IPD Y Pipe. This is an easy and straight forward R & R (remove and reinstall) bolt on upgrade.

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.

Race plenum and throttle body.



Fits:
Porsche 997 Turbo 2007-09

Adding bolt-on horsepower to the 997 Turbo is a continuous quest by many enthusiasts looking for more power. Reverting back to old tuning technologies, Agency Power has developed a larger throttle body and plenum kit for the Porsche 997 Turbo to gain added performance. The point of a larger throttle body is to get in more air.

The more air you bring in, the more power you make. The 997 Turbo's engine intake system works off pulses, so how that air is diverted to either side of the engine is not as important as the volume incoming. The plenum kit includes an OEM Porsche Cayenne Turbo throttle body (part# 94860511503) which is a direct bolt on and plug in for the electronic throttle control with no modifications needed.

This throttle body has a 77.64mm inner diameter compared to the stock one of 75.64mm. We chose to go with this smaller diameter throttle body to give the car more low end horsepower and torque. If the diameter of the throttle body is to big, it will increase turbo lag and performance gains will only be made at the mid to top end RPM range. Since most 997 Turbo users drive their car on the street and track, we developed this product to substantially increase throttle response and improve "usable" power.

The Agency Power plenum kit is made using high quality 6061 aluminum that has been TIG welded and pressure tested in a T shape to mimic the OEM design. The CNC machined 4 bolt throttle body flange features a groove to accompany a rubber o-ring to ensure a secure and sealed fit with the OEM Porsche Cayenne throttle body. The T plenum features the necessary fittings for stock vacuum hoses and breather lines and includes a 1 way check valve needed. Each T plenum is powder coated gloss black for an OEM look and includes new silicone couplers in black and worm clamps to secure it to the factory intake manifolds. The installation of the plenum requires removal of the factory airbox and Y pipe to access the component.

Installation of the Agency Power plenum kit DOES NOT require the ECU to be flashed. The factory ECU will adjust accordingly to the change in throttle body diameter. However, corresponding mods including an ECU flash will only bring out additional power. As it stands alone, the plenum kit will add a bolt on 20 wheel horsepower to your Porsche 997 Turbo. As tested on a VR700 kit, the plenum added nearly 45 horsepower and 60 ft/lbs of torque. Splitting and diverting the air flow and directing it towards the cylinders at a much higher air speed.

Recommended installation time is approximately 3 hours.

HP Gains: 40-45Bhp. 60 ft/lbs of torque

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.
