Different types of S/C's.

From DDM when I inquired:

"The biggest difference between our kit and the Mallet kit is the type of superchargers we are using. The Mallett kit uses a centrifugal type which builds boost based on RPM. This type of supercharger offers little pressure below 3-4K RPM's, and as you can see by the dyno that they post on their website, the kit makes it peak power at Redline. The peak power they are seeing at the wheels is 256HP but with only 208 ft/lbs of torque.

The supercharger that we are using is a positive displacement supercharger which moves a fixed volume of air for every revolution. This ends up giving the car a bigger engine feel. From just above idle to redline you see an instant 4.5psi of boost the whole way. This has the effect of raising the torque curve everywhere throughout the entire engine RPM band. We end up with 195HP and 195 ft/lbs of torque and that is non-intercooled with our peaks being more in the mid range of the power band 3-5K RPMS. This makes the car much more drivable around town and on the interstate. With our supercharger set-up a lot of our customers will not have to down shift when they want to pass, since they have torque available down low."

The best I've seen for this kit is 14.1 with bolt-ons. I think that same car is capable of breaking into high 13's with some practice and grip.
