Project: Porsche 997 GT2 rear spoiler custom-made
The fastest road-legal 911 ever produced at the time! The Porsche 997 GT2 brought a truly astonishing level of performance to the 997 platform with two turbochargers on a 3.6-liter six-cylinder engine. But who doesn’t know it? Your own dream car is never completely perfect, because if you had built it yourself, you would probably do some details differently. Our customer had exactly this feeling and contacted us with his wish to complete his dream car.
Order:
Optimization of the aerodynamics of a Porsche 997 GT2 by raising the wing board and changing the wing profile. “Would be cool if it looked like it was from Porsche”. Let’s go!
Inventory:
A CFD simulation is used to simulate a run in a wind tunnel. For this purpose, the relevant part of the Porsche is scanned in its unaltered state and the data is processed so that plausible results can be displayed. The model can now be used to vary the wing board and determine the optimum height. Just set it higher? Unfortunately, the shape of the car does not allow this. The feet of the sash do not have a simple geometry and also run outwards in height. This meant that we had to design the inner workings of the lift adapters in a slightly more complex way to compensate for the bore offset. Even the prototypes look suspiciously inconspicuous. The end product is milled from a solid ABS block and is given the original Porsche paint finish. Some time later and 5 cm higher, the entire rear end not only looks better, but also stands better in the wind.
A nice side effect?
The airflow directly above the engine cover has also been optimized. More downforce for the rear axle and more air for the engine!
That’s not enough for us!
The customer has suggested a Gurney Flap on the wing board. In the course of the project, we also learned that this modification has an enormous drag value and therefore has a negative impact on aerodynamics. We therefore scanned the existing wing lip and redesigned it. The lip now has a different angle and has been slightly extended. The laminar flow path above and below the wing board now meets further behind the physical end of the wing, which lengthens it.
