After a very extensive R & D program we are proud to launch the new 981 IPD 82mm Competition Plenums. We only offer "Competition" versions of the 981 Plenums which upgrades the factory 74mm throttle body with the larger 997 GT3 82mm throttle body. This combination has proven to be considerably more popular and deliver even more performance. This Competition version will work with both 3.4L "S" and 2.9L "Non-S" applications.
The 981 intake is nearly identical to the 987.2 intake. Porsche made a few upgrades with the 981, most notably being that the 981 draws outside air from both driver and passenger air intakes instead of the driver's side only as previously found with all 986, 987 and 987.2 applications. IPD has developed a custom silicone hose designed to perfectly fit the larger 82mm TB and considerably improve air flow.
The new 981 Plenums also benefits from the internal dimpling effect that we are now implementing on all future Plenums. This internal dimpling allows us to control the boundary layer and maximize air flow. Just like a dimpled golf ball travels farther than a smooth golf ball. Controlled turbulent air creates less friction and "tumbles" over a given area more efficiently.
Power gains with the 981 Competition Plenum are virtually the same as with the 987.2 Competition Plenum, putting down 20 horsepower and 16 foot pounds of torque at the wheels. The bulk of the power gains from the IPD Plenum begin around 4000 rpm, continues all the way through to redline and become fully realized in the 6000 rpm range. IPD performance gains stay above both factory power curves throughout the entire rev range
NOTE: All IPD products are designed and manufactured to deliver increased performance for Porsches that are strictly driven on public roadways. All IPD Plenums come with a full 2 year manufacturer’s warranty to the original purchaser that guarantees all IPD product will be free of any manufacturing defects or cause of any issues or problems related to the vehicle’s engine. All IPD Plenum warranties are expressly voided if installed and driven off-road or on race tracks.
About
Innovative Pro Design (IPD) was founded in 2004 by Mike "Turbo" Kirakosyan. The IPD Plenums were conceived, developed, tested, proven and manufactured in the heart of the Porsche Tuning capital, Southern California. The IPD plenums evolved from the age old hot rod philosophy of "never leave good enough alone". The genius behind the IPD Intake Plenums is not only the patented "Y" design but also the geometry of diversion areas, optimization of bore sizes and internal surface area manipulation.
Virtually all performance upgrades stem from man's innate and unstoppable quest for speed and power, and the IPD Plenums are no exception. Turbo Mike's "Need for Speed" is embedded in his DNA. His relentless pursuit of performance extends well beyond the Plenums. Mike is an accomplished fabricator, engine builder, tuner and all around Porsche expert.
Back in 2000 Mike's personal 3.8 liter Porsche Twin Turbo was a daily driver developing over 1000 horsepower (at the flywheel) and capable of unheard of acceleration . This car was the test mule for all initial plenum designs and performed over 1000 dyno pulls during it's extensive developmental process.
Mike's continual quest for more power combined with his passion for Porsches have yielded the ultimate Porsche performance upgrade, the IPD Intake Plenum. Mike spends endless hours on the dyno continually testing, tuning, modifying and retesting each plenum model until the perfect plenum design is achieved for each specific Porsche model.
Early implementation of diversion splitters were cast and polished then installed inside the OE factory Porsche air distributor. These early "shoe horned" splitters yielded power gains but still required a larger opening near the throttle body for optimum performance. This is where today's single cast and machined IPD Plenum really performs and warranted a patent design.
Although the concept of the patented "Y" design plenum appears simple and straight forward there is a science behind the diversion areas and optimization of volumetric efficiencies. It's only after countless prototypes and endless hours of dyno testing that an actual Plenum design is put into production.
The entire IPD team is dedicated to providing the absolute best after market performance products for Porsche. IPD stands behind each and every plenum and our promised power claims with a 100% money back guarantee if not completely satisfied after 30 days.
We back up our dyno proven performance claims with honest, knowledgeable and friendly service. So many manufacturers inflate their performance gains with questionable and unqualified dynos. We only advertise performance gains that we can consistently replicate and promise will be realized on our customer cars. (Photo of Plenum being installed on Porsche)
IPD has substantially expanded its product range over the years and will continue to maintain this growth with new and innovative products. Even the current existing IPD product line, now covering more than 30 Porsche applications, under goes continual scrutiny and fine tuning improvements.
All of IPD Plenums will continue to come standard with customer satisfaction guaranteed, No dreaded check engine lights or warranty voiding issues and most important, impressive performance gains sure to make any Porsche driving enthusiast smile.
Thousands of IPD Intake Plenums have been sold with over a 99% customer satisfaction rate which few manufactures can claim in any industry. We even have the skeptics covered with our 100% customer satisfaction guarantee. So if you're ready to increase the performance of your late model Porsche then look no further than the ultimate Porsche bolt on performance mod, the IPD Intake Plenum.
