991-Plenum-01 thumbThe new 991 Carrera is arguably one of the sexiest Porsches to come out of Stuttgart in recent years. But like most Carreras, power output is controlled to meet a "performance target" that satisfies the masses and not the dedicated Porsche driving enthusiasts. The latest generation of Carreras continues the trend of 911's gravitating towards a GT Touring class and away from a sports car specific category. But this doesn't alter the eternal quest for more power and improved performance, and IPD is there to scratch that proverbial performance itch.

In typical Porsche fashion, new car model launches and new engine launches tend to be staggered. The engine in the new 991 remains relatively unchanged from the previous 997.2 Carrera. Porsche is famous, even genius, for developing components with a very long shelf life that can be utilized for many years as well as being shared with multiple model platforms. The intake system on the 991 is "nearly" identical to the 997.2 Carrera. Changes had to be made to the Plenum casting to accommodate an additional air-temp sensor which proved to be more challenging than expected as well as different hardware.

 

The 991 Carrera employs the 82mm throttle body just like the 997.2 Carrera before it. This means there is no "Competition Plenum" option available. Performance gains remain at 15+ horsepower and 14+ foot pounds at the wheels. As with most IPD Plenums, the bulk of the power gains are realized in the mid-range where they are most used and enjoyed. Unlike other mods, the IPD Plenums deliver net power gains across the entire rev range. The owner of our 991 test car said, "The Plenum transformed the car, giving it the boost in power it needed." He even added, "my wife asked me if I did anything to the car", of course he appropriately answered, "No Honey".

We made a few final changes to the machining process of the 991 Plenums which are now complete. 991 Plenums are being assembled as quickly as possible to meet the back ordered demand but should readily available by the time you read this article. Installation time is about 4 hours and is a relatively straight forward process for a qualified Porsche technician. Feel free to give us a call with any questions or place an order.
