As the title says should I get the roush or kenne bell supercharger? I have been searching all the forums and cant make up my mind. I have seen some really good numbers posted from the roush, but not alot from the kenne bell. Is the KB not a good option on the new 5.0 or is it that just not many are running it. My goals are to have a fast daily driver that has the potential to go 9's when I get a forged bottom end. I also want my car to stay streetable. If there is a better option feel free to let me know thanks.
