Biggest in terms of displacement...which means less block material as it was bored out...and then all those titanium pieces...hehe -- I'm not surprised.

(correct me if im wrong here, id rather know the facts than just have oppinions LOL)

No roots supercharger is going to have that whine, anymore. Since EATON pretty much owns that market, the new TVS series rotors are ridiculously quiet.
And as for throttle response...well...The LSA has 350+ lb/ft on tap at 1000rpms....you tell me.

Since the LSA/LS9 uses the new gen roots supercharger TVS series they are quieter than the old gen superchargers. Superchargers power is instant and have no hesitation. Some folks don't like roots because you have instant power on the low end and makes it harder to put the power down.

+1, Well said.
