I have some input despite my lack of knowledge, but I honestly don't understand why most people prefer to turbocharge their twin instead of supercharging it *, which changes the dynamic of the vehicle more significantly.

First off, there is turbo lag, and no matter how minor, the linear power progression of the stock naturally aspirated engine will be thrown off. In the case of a supercharger, the torque curve can be more linear and will offer a boost right from the beginning even at lower RPMs.

Since we are only talking about 300 horsepower at the wheels here, we can see that the turbo wouldn't need to be large and can start spooling at a very low RPM, but in my mind that still does not compare to a supercharger for the same application. There have been superchargers for this car that can output above 300 horsepower at the wheels safely, so I think that is more comparable to the Porsche 911 GT3's more powerful naturally aspirated engine.

* Edit: We are only talking about producing 300 horsepower in the case of this thread.
