Im trying to decide what supercharger to get in the long run. I know i want a basic beginner supercharger,, in looking at the Novi 1000, the Powerdyne that has 6psi, and the Vortech that pumps out 5psi, not sure what trim that is. Which one of these three is better and why?? Im looking to have a low 12 second car when its all said and done, which will help me achieve this the best? Im just looking for best durabilty, quality, performance, and which one can be modified the best? Thanks ahead a time!!!
