We are proud to present our newly developed Plenum for the Porsche 997.1 Turbos!
With this extreme high flow Plenum, the performance of your 997 generation 1 will increase!
- Available for OEM (74mm) and GT3 (82mm) throttle body
- do88 plenum is Y-shaped for improved air flow. Our plenum flows 34% better for GT3 throttle body and 18% better for OEM throttle body compared with the OEM plenum (see diagram below).
- High quality casting pipe with CNC-machined connections
- Smooth internal surface for best air flow
- Comes with all necessary accessories for installation
The OEM 997 Turbo plenum is T-shaped which means the air flow from the throttle body abruptly change direction when it´s divided to each side of the intake manifolds. It makes sense to design a plenum with a Y-shape instead of a “bank into the wall” T-shape. During the development process of this plenum we spent a lot of time with flow simulations of the internal Y-shape design. We made both flow simulations on our CAD system and real tests on our own SuperFlow SF-1020 flow bench on 3D-printed models. The results of the final design were very impressive the do88 Plenum totally outperform the OEM Plenum by 34% increased flow at the same pressure drop! To be able to manufacture this final design we choose to make a 3D freeform designed casting. This construction adds a lot of performance but not so much of extra weight. We designed the outside of the plenum to add as little weight as possible to the plenum. do88 Performance Plenum weight 0,80 kg (1,76 lb) OEM plastic pipe weight 0,28 kg (0,62 lb) and competitor cast performance pipe weight 1,19 kg (2,63 lb)!
This is a great upgrade both with the OEM 74 mm throttle body or the more extreme 82 mm GT3 version.
