Superchargers, due to their RPM-dependant nature, take less time to re-pressurize the intake.

The reason why this is important to me is because I use this car for AutoX and "canyon carving". So I often have to feather the throttle to balance the car in a corner. With a turbo car, I end up dumping pressure and my corner exit suffers. But in this car, even with it's moderate power, I can get great corner exits because the power is always available. I want to compliment that nature of this car, not change it.

You can actually get similar response from a turbo. But that requires an anti-lag tune which impacts turbo reliability. And that's not a compromise I wish to make.

Now, I really want the Innovate twin-screw because a Positive Displacement blower is even more responsive than a centrifugal on like the Vortec. But since every day the Innovate charger looks more and more like vaporware, I'm looking at the Vortec now.

A smaller mid-frame or twin-entry (twin-scroll) turbocharger should have excellent transient response that you're looking for. Nothing like a supercharger or N/A though.
