So I'm considering two different supercharger packages from brenspeed. Im going to stick with these guys because there service has been amazing. I cant decide which package to get...the saleen stage 3 kit or the edelbrock stage 1. I know my goal of a low 12 sec street car is attainable with either, but which one do you guys think is better and why? My main concern is reliability, but also efficiency. Which supercharger has the most power potential? Thanks for your input...
