Rotrex superchargers are pretty sweet. Not so much for the bit of extra power they make due to the increased efficiency, but for what they are, a rotrex supercharger.
If money was not an issue when it came time to supercharge the K I would go with a rotrex and have a custom hood made with a functional hood scoop to feed the top mount intercooler (or is it an aftercooler).
Honestly though for the difference in price from a jackson. I am not sure that it is worth it.
I think a setup like this would be neat
