Preparation for the STILLEN supercharger

Throttle

Now I understand why you kept the type of supercharger a secret for so long. It has been a while since I have been able to check up on this topic and I am a bit disappointed to find that a centrifugal was chosen. Why?

The TVS is nothing short of an evolution in supercharger design yet it was not used. Did Vortec release some ground breaking new design that is on par with the TVS advancments? Or was a centrifugal chosen for ease of mounting, maintaining the stock hood or just because Stillen is more comfortable with them? Was the TVS even tested? How did it compare to the Vortec unit you are using? What made Stillen choose something other than the best?

I am asking because I respect Stillen and I know that you guys did research a lot of different options before picking the Vortec... what made the difference? Please help me to understand.
