Porsche 911 991

These extensions may be necessary on cars which have both an upgraded intake as well as a taller diverter valve (such as the EvoMS).

These will require some 6mm nuts and bolts to attach to the car (8 of each) which are not provided.

Have a broken button on your elbow rest? This 3D printed replacement is a direct replacement - no tools required.

Please note that this is a 3D printed part, not injection molded like the factory part. Therefore it will have minor cosmetic flaws on the surface. These minor flaws are not easily noticeable once installed.

Need to install a 105mm rear main seal into a 991 or a 997.2 Porsche 911? Make sure you set the seal to the proper 7mm depth from the surface of the crank flange! If you install the seal without a tool that controls the depth, you'll likely install it too deep, and you'll have a high risk of a leaking seal.  It's simply too time consuming to do the job twice, so do it right the first time!

This is an affordable alternative to the costly (~$400) factory tool from Porsche. Simply bolt this tool to the crank using the flywheel bolts until the tool bottoms out on the crank. Remove the bolts, verify that your depth is even, and you're done!

This CAD designed tool is 3D printed plastic, and is safe to use on your seal without risk of damaging it or the bore that the seal sits in.

Upgraded aluminum intake piping for the 991.2 3.0T Carrera / T / S / GTS

The 991.2 Carrera is the first Carrera to abandon natural aspiration in favor of forced induction by utilizing turbochargers. Porsche decreased displacement to 3.0 liters (from 3.8L & 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.

Like 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.

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 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.

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 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.

Complete kit, with 3D-printed manifold assembly. Fits 991.2 3.0L and 3.8L engines.

The Girodisc system is a direct replacement for the OE disc with the addition of our provided caliper spacers. Our rotor is slightly larger than the OEM rotor at 350mm versus 340mm providing greater braking force and cooling capacity. The Girodisc front rotors are approx 21.0 lbs vs. 24.4 lbs for the stock units. This reduction in rotational and unsprung weight allows for quicker acceleration and suspension response.

The central hat section of our rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum. The disc is made from our own proprietary cast iron, poured in the USA and machined from start to finish in house at Girodisc. The rotor utilizes a curved vane design, developed in racing to act as a centrifugal pump to force cooling air through the disc.

The rotor and hat have a floating mount system, which utilizes 10 high strength alloy steel drive pins, manufactured by Girodisc in the USA to our own specifications and cadmium plated for a long lasting corrosion resistance. These pins take the load from braking actions while maintaining the axial and radial float between the hat and disc. The pins are secured by class 12.9 cap screws with hardened washers. In order to keep the rotors from making noise when cold, the pins are mounted with anti-noise spring washers on the rotor side which allow the rotor to grow with heat expansion but eliminate the rattle and noise associated with floating rotors. This float also allows the rotor to self center between the pads.

Once the Girodisc system is in place, simply replace the cast iron rotor when needed.
