The new 992 Turbo engine is another modern marvel from Porsche. We were fortunate enough to have unlimited access to a 992 during our extensive development and testing program. This unrestricted time frame proved to be invaluable, allowing IPD to scrutinize every engineering and design aspect in an effort to deliver the best performing Plenum possible.
Like all previous IPD Turbo Plenums, the 992 Plenum is a product of efficiency that produces substantial HP and TQ gains through a superior and patented “Y” design that manages and delivers optimized air flow for enhanced engine performance. The Plenum has been proven to produce substantial net gains across both power bands and is guaranteed to elevate the driving experience of any Turbo.
Development started with a 1D simulation to optimize the treatment of pulse peaks in the intake tract using different pipe geometry and known engine parameters of the 992. We then graduated to optimizing 2D slices of the plenum in CFD, paying special attention to places where adverse pressure gradients that might cause separation. This allowed us to adjust curvatures on the plenum faces and build up our understanding of what was happening inside the pipe at full throttle.
After we were pleased with the 2D slices we graduated to 3D adding in all the geometry to make this a plug and play bolt-on part with optimal performance characteristics. After hundreds of geometrical and CFD iterations, we were pleased with not-only the increase in mass flow compared to the stock intake, but also the uniformity of the charge pressure and velocity across the 2 branches.
The efficiencies of the Plenum dramatically reduce initial turbo lag down low helping access the power and torque sooner, but the bulk of the power and torque gains are realized from 4000 rpm to redline, where we need and enjoy it most. The HP and TQ gains continue to increase and out-perform the factory air distributor as you climb through the revs. Peak gains of 35+ wheel HP and 35+ wheel TQ are achieved above 6000 rpm. The 992 Turbo Plenum delivers very impressive power and torque gains that will raise the performance bar of the already potent Turbo as well as raise the hairs on the back of your neck.
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.
