Engine Components-IPD Intake Plenum Fits Porsche®991 Turbo
The perfect compliment to exhaust upgrades, this high performance intake plenum from Innovative Pro Design provides substantial power gains by increasing the efficiency and flow of the engine's air intake system.
The incredible 991 Porsche® Turbo received a completely redesigned exterior but the engine remained virtually identical to the previous model Porsche®997.2 Turbo. This latest Turbo is the most powerful, revolutionary and capable Porsche® Turbo to ever come out of Stuttgart. This latest generation Turbo engine, titled the 9A1, delivers 520 HP (560 HP with the "S") and once again, raises the proverbial performance bar in the sports car world.
The new Porsche®991 IPD Turbo Plenum is nearly identical to the previous Porsche®997.2 Turbo Plenums. The new IPD Turbo Plenum is offered in one single 74mm version which utilizes the factory 74mm throttle body. The Porsche®991 Turbo intake manifolds are smaller than the Porsche®997.1 Turbo manifolds which is great for improved boost response and gas mileage but less than ideal for making substantial power gains. The 74mm TB provides more than adequate flow for these more restrictive intake runners eliminating the need for a larger 82mm "Competition" version.
The already explosive power of the Porsche® 991 Turbo can be further increased with the new Porsche®991 Turbo IPD Intake Plenum. The patented IPD Plenum design works exceptionally well with all forced induction applications and the Porsche®991 Turbo is no exception. Power and torque increases provided by the IPD plenum are impressive and stay well above all factory power curves from launch to redline. Maximum power increases take place in the mid-range where it's most needed, most critical and most enjoyed.
The Porsche®991 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.
The Porsche®991 Turbo requires an "adaptation" period that can be fully realized with either a series of hard pulls on the dyno or a series of spirited driving sessions, which of course IPD recommends only be performed on a closed course circuit. Installation of all Turbo Plenums is highly recommended to be performed by qualified and trained Porsche®technicians.
Superior and more efficient design over the factory intake.
The IPD Plenums are products of efficiency that simply improve intake air flow and increase air velocity. The “Y” shape design and dimpled interior surface make air flow more laminar (less turbulent) dramatically improving power and torque across the entire RPM band. Smoother more optimized intake air flow will improve the performance of any engines. The more efficiently an engine breaths, the more efficiently it produces power.
Deliver impressive power gains regardless of modifications.
The superior design of the IPD Plenums optimize flow while increasing air velocity. Period! This applies to any Porsche®engine, producing any level of power. The patented “Y” design delivers impressive performance gains for both bone-stock and highly modified Porsche® The more efficient design of the IPD Plenum will always outperform the factory air distributor. The factory intake will become even more detrimental to performance as your increase the power and torque outputs. The bigger the power, the better the IPD Plenum performs.
Produce substantial gains for both turbo and NA applications.
The Plenums always deliver considerable gains on both turbo AND naturally aspirated engines. It’s a fact that the Turbo Plenums do produce more power than the NA Plenums. But the Turbo engines also produce more power. The fact is that the percentage gains of the different Plenum applications are actually almost identical, around 8-10% depending on the specific model.
Do not require an ECU flash and will not cause a CEL.
IPD Plenums should never cause a CEL or require an ECU Flash. If a Plenum is installed correctly there should be no fault codes or running issues, only solid performance gains across the entire RPM band. The only issue that could possibly arise is the need for a new MAF sensor if you already have a degraded sensor or perform a TB adaptation. There is absolutely no need to re-flash your ECU after installing an IPD Plenum, Period! Although any reputable Porsche tuner could further optimize an ECU program to achieve even greater performance gains with the Plenum installed.
Aluminum Plenums run cooler and don’t suffer from heat soak.
The Aluminum Plenums do NOT experience heat soak under driving or racing conditions. It is true that aluminum has a higher thermal conductivity than plastic. In fact, aluminum is 650 times more thermally conductive than plastic and has a specific heat capacity that is 550 times higher than plastic. This means the aluminum Plenum actually spreads the energy it’s exposed to 656 times faster than the plastic and can store more than 550 times the amount of energy per unit mass. Bottom line, aluminum can absorb more heat than plastic, but it also takes considerably more energy to heat up and it's losing that energy way faster than the aluminum allowing the IPD Plenum to remain cooler from outside ambient air under driving conditions, ultimately improving engine performance over plastic. Plus, why would Porsche utilize aluminum intakes on GT3’s, GT2’s, Cup Cars and Cup R’s?
