I did a bit of reverse engineering on my own part now that I have a scanner !
here is the superposition of a stock 986 plenum, and my carbon fiber one !
As you can see, the transition is more straight between the two tubes and it has nicer bends.
For that I had to move the throttle body to the left and forward a bit to clear the starter solenoid !
What took months before would take only hours now !
