A customer interfaces with Ruf personnel to discuss desired performances:
1. Alois orders a DISASSEMBLED Porsche from the factory.
2. He adds or deletes components as he deems best for overall performance.
3. His staff assembles comonents, welds the body panels, and installs Ruf parts as necessary. If performed correctly, the synergy works for the vehicle.
4. The vehicle is road tested to verify desired performance parameters.
5. The customer receives the Ruf fabricated vehicle.
The whole is greater than the sum of its parts with this: design, fabrication, assemble process.
Obviousle purchasing some parts to enhance one's vehicle does not approach the aforementioned Ruf total build process.

As far as the Yellowbird, its power ratings have been reported at around 550BHP, but that's with the manual boost controller dialled beyond 1.3Bar, the official rating of 469BHP was made at 1.1 bar.
