Just wait for the Elda turbo kit. I'm certain it won't disappoint. And it will be the only CARB legal turbo kit up to date.

Both SC's are CARB legal also

In the end, it will be your wallet making the decision. You can see which direction I went.

 

i supercharger as just as much potential as a turbo, just depends on how much you work with it and how much money you're willing to spend.....

and like the people above have said... the roots blower has instant power, while the centrifugal blowers build through the rpm range.....

put it this way... roots blower replaces your intake manifold, centrifugal blower is like a turbo but doesn't work off of exhaust gasses.... this is why you will see intercooleers or aftercoolers with centrifugal blowers and not see that with roots blowers.....
