A centrifugal makes a better package than roots.
1. can be intercooled (as a blow-through)
2. no visible mods (like that giant cop-magnet hole in the hood)
3. weighs less
4. requires less parasitic drag per pound of boost
5. lower charge temperature
Disadvantage: not much torque increases until it's spun up, so it needs a looser convert to launch.
Advantage over NA: equal and tuned header length is relatively unimportant, but should use primary OD based on power delivered, not engine size.
