Wow this post is old, but I'll respond to it and maybe you'll see it.In order to make one of these chargers work you would need the 03 cobra manifold. And this would only bolt up to the 03 cobra heads, so it is not very feasible at all to do this with the 96-98 cobras, as they had two intake runners per cylinder as opposed to one like on the 99 and up DOHC heads.
Kenne Bell does make superchargers for the 96-98 but they are extremely expensive. Yeah its nice to have the low end of a twin screw blower but I can't justify the price.
Best bet would be look into a vortech or procharger centrifigul supercharger system. They are pretty cheap and easy to install. With stock bottom end, run no more than 8lbs of boost, get a conservative tune, and you WILL see over 400 rwhp. These cammers love forced induction.
