The Plenum has been proven to delivered substantial net performance gains across both power bands from launch to redline and is guaranteed to elevate the driving experience of any Carrera.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eDevelopment 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.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eAfter we were satisfied 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.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe 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 begin at 4000 rpm, where it is needed and enjoy most. The HP and TQ gains continuing to grow and out-perform the factory air distributor as you climb through the revs with peak gains of 30+ wheel HP and 32+ wheel TQ are experienced in the 6000 RPM range.\u003c\/p\u003e","brand":"IPD","offers":[{"title":"Default Title","offer_id":30869105311883,"sku":"IPD-91274-3.0","price":995.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1003\/2430\/files\/3w8a8599-edit-photoshop-fix-1000-1000-80_cb4adb22-f9c3-4427-b97c-ebb99f64d267.jpg?v=1716241092"},{"product_id":"ipd-991-2-turbo-s-gt2rs-plenum","title":"IPD 991.2 Turbo\/S\/GT2RS Plenum","description":"\u003cp\u003eThe 991.2 Turbo Plenum upgrade delivers staggering engine power and torque gains that will raise the performance bar of the already potent supercar as well as the hairs on your neck.

Porsche made very few changes to the intake system from the 991 Turbo to the 991.2 Turbo. Ballistic acceleration and a top speed of over 200 mph places the new Turbo in a very elite class of supercars. But of course the IPD Y-Pipe (and Plenum) raise the performance bar even higher for Porsche driving enthusiasts who seek fighter jet performance from their German Turbo missiles.\u003c\/p\u003e\n\u003cp\u003eIPD invested countless hours of R\u0026amp;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 40+ wheel HP, 50+ Foot Pounds of Torque, improved boost response and more linear power and torque curves.\u003c\/p\u003e\n\u003cp\u003eAs 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 “non-round” design with dimpled interior surface cannot be achieved with conventional round tube construction.\u003c\/p\u003e\n\u003cp\u003eThe 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.
