Example, drive the 3.3 just like the 5.0, and it's a 1.99 liter. Does a 3.98 quad rotor sound good?
So, when we drive the supercharger just like all the small blowers, it's a 8.3 liter. This is why it's physical dimensions are so big. It's a 8.3 when comparing to a 3.3. Therefore, it's the 8.3 is still 1.7 liters bigger than a quad 3.3.
More info, turning the 5.0 via the male rotor to 18,000rpm, the female rotor is turning 10,843. Now drive the female rotor to 10,843, the male rotor is then turning 18,000rpm. Same airflow, different input shaft speeds. Just like a rear end, outdrive, transmission, etc.
