Description:

IPD Y Pipe & Plenum for 991 Turbo / S, already plumbed for Meth Injection.

The work to plumb these for a meth kit has already been done.  You can plug the holes and use as is (add meth later), or install with meth kit build.

All parts included.  Price includes shipping in the US.

NOTE: I also have D088 Porsche Turbocharger Inlet Hose Kit - DO88 KIT179S for $530 shipped.  Would pair excellent with these IPD parts for a perfect stage 3 or 4 build.  do88 Sale Thread:



IPD Porsche Plenums & Y-Pipes

The revolutionary and patented design of the IPD Porsche Plenums improve intake air flow by replacing the factory plastic "T" style design with a more efficient, cast aluminum "Y" design. This innovative “Y” diversion area of the IPD Plenums split and channel intake air flow reducing air flow turbulence and increasing air flow velocity. This superior and proven design ultimately results in considerable power gains throughout both horsepower and torque curves. Performance is also enhanced with our uniquely dimpled interior surfaces which create improved boundary layers further optimizing intake air flow characteristics.

IPD also offers Y-Pipes for turbo applications. Our turbo Y-Pipes feature an accentuated merge collector area that allows the intake air flows from each intercooler to meet in a more parallel fashion as air enters the throttle body, minimizing turbulence and increasing boost response. The combination of the Plenum and the turbo Y-Pipe will deliver substantial power and torque gains guaranteed to transform your Porsche driving experience.



IPD Plenums have earned the reputation of being the single best “bolt on” performance upgrade you can possibly install on a late model Porsche. The IPD Plenums provide the best power per dollar return in the Porsche after-market industry today. They have been tested, challenged and proven repeatedly to deliver our impressive claimed power gains.

Every IPD Plenum and Y-Pipe in our product line goes through a very rigorous and scientific R & D program backed with extensive dyno testing and tuning to deliver the maximum engine output possible. The countless hours we invest testing, tuning and manufacturing each product, ensures you are getting the highest quality and best performing products on the market.

All IPD products are designed and manufactured in the USA. All Plenums and Turbo Y-Pipes come with a 100% money back guarantee if you are not completely satisfied after 90 days. We stand behind our entire product line and promise the impressive performance gains we advertise. Join the thousands of satisfied IPD customers who are enjoying the increased performance and elevated driving experience provided by their IPD Plenums and Turbo Y-Pipes.

991 Turbo /S IPD High Flow Y Pipe | Part #91500

The latest 991 Turbo from Stuttgart is another milestone mechanical achievement that once again raises the performance bar to a level reserved for a very elite group of supercars. Ballistic acceleration and a top speed of just under 200 mph makes it the most powerful 911 based Turbo to date. But of course there is always room for performance improvements for Porsche driving enthusiasts looking to raise the performance bar even higher.

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 35+ wheel HP, 40+ 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 “no-round” design with dimpled interior surface cannot be achieved with conventional round tube construction.

The 991 Turbo 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 install.  





 

991 Turbo /S Plenum

The incredible 991 Porsche Turbo received a completely redesigned exterior but the engine remained virtually identical to the previous model 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 991 IPD Turbo Plenum is nearly identical to the previous 997.2 Turbo Plenums. The new IPD Turbo Plenum is offered in one single 74mm version which utilizes the factory 74mm throttle body. The 991 Turbo intake manifolds are smaller than the 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 991 Turbo can be further increased with the new 991 Turbo IPD Intake Plenum. The patented IPD Plenum design works exceptionally well with all forced induction applications and the 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 midrange where it's most needed, most critical and most enjoyed.

The 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 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.
