Hey Dino,
The "twister" or what Green refers to as a "venture" IMHO doesn't do anything - it's the length and surface area of filtration, the quality of the filtering media, and the heat shield that your really buying here. I thought that was understood by everyone considering the purchase - even then the size of this unit probably wouldn't do much for a non-SC engine. My concerns about the fins being broken were more about build quality and less about how it would affect performance. You're getting a mongo filter here stuck on a huge pipe - combine that with a supercharged engine and wide exhaust and there's no doubt about a performance gain.
On that last topic, unless you open up your exhaust, putting on a performance intake wont do much for performance - it will eliminate some restriction on the intake side, but without doing anything to the exhaust you're really wasting the benefit of having it (though it does give the engine a more aggressive "sucking sound" under the hood). The real performance gain comes when you change out both the exhaust and intake.
