"Innovate" kit is no longer for sale. They were just the North America distributor for the Sprintex kit. Sprintex is selling it themselves in North America now. That may account for your seeing Innovate kits "Out of Stock", etc.

A positive displacement blower like a twin screw is supposed to feel like the name implies... that you just have more displacement in the engine. Take a 2.0 liter and make it feel like you're driving a 2.5 or 3.0 liter.

When it comes to superchargers/turbos, everyone has a preference. Best way to find out what you'd be happy with is to just ride in them, if possible, even if it's not this car, to know the characteristics of each FI type.

Btw, the Vortech, I believe, was the first supercharger to market for this car, and they have gone through numerous revisions to upgrade their kit since then. Still a good choice as well.
