Porsche decreased displacement to 3.0 liters (from 3.8L \u0026amp; 3.4L) but was still able to produce 414 HP and 368 TQ with twin turbos. The IPD Plenums provide substantial performance gains with naturally aspirated engines, but our proven and patented design delivers even more impressive HP and TQ gains with turbo applications, like the 991.2 Carrera.\u003c\/p\u003e \u003cp\u003eLike all IPD Plenums, the 991.2 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 and improved boost response. 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 \u003cp\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 \u003cp\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 \u003cp\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\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\u003cli\u003eManufactured using only the highest quality materials\u003c\/li\u003e\u003cli\u003eGives your vehicle a truly unique and exotic style\u003c\/li\u003e\u003cli\u003eOutperforms the competition with dyno proven results\u003c\/li\u003e\u003cli\u003eA taste of luxury combined with unbeatable power gives you a superior edge\u003c\/li\u003e\u003cli\u003eFitment guaranteed and withstands the test of time.\u003c\/li\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003ciframe src=\"\/\/www.youtube.com\/embed\/g0juw9YcEGY\" width=\"560\" height=\"314\" allowfullscreen=\"allowfullscreen\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e","brand":"IPD","offers":[{"title":"Default Title","offer_id":52025954566436,"sku":"GGDS_91274-3.0","price":995.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0671\/6801\/0532\/files\/3w8a8600-edit-1000-1000-80_c46b02e5-a2bc-416f-b7df-2b095ea8d4fb.jpg?v=1771513269","url":"https:\/\/autohousesupply.com\/products\/ipd-9912-carrera-non-ssgts-30l-74mm-plenum-17-19-91274-30","provider":"AutoHouseSupply","version":"1.0","type":"link"}
