@Markus. Havin one of those bad day huh lolll

Easy yes but not that simple (apparently). It's well known that a small TB will restrict air intake however the 'infamous' larger TB idea may actually reduce velocities even more than the stock TB for a particular engine. I already have the formula to solve the TB-vs-Size air flow but without the combustion domain, ratio and valve m/sec specs, its nearly impossible to find where the imposed limitation(s) are - less helpful to find the optimum geometry for the air delivery.

Using CFD(nastran) of course and already asked onto another forum a few weeks ago. Unfortunately and as you know your country folks, as soon as you mention about their Porsche-performance-anything, they get offended and shut down on ya leaving you guessing. It's never cool but I respect that. No offense to you personally bud.
