John Scott Posted January 5, 2002 Share Posted January 5, 2002 In response to a previous post, a supercharged engine produces boost, only when you put your foot down. The rest of the time, cruise, light part throttle, you have vacuum just like NA. A good relief valve helps to keep air from "stacking" when not in use. Having just retired my 4.3 Procharged Z, I can say the system is effecient, relatively inexpensive, staraight forward and simple to install. Clearance on a V8 will pose a problem with some if not all the many units availible, in the JTR position. I pulled down high twenty mpg on my road trips. On pump gas, at 12 or so psi and under it was rock solid reliable with huge gains in hp. It is only when I tried to push the limits of the pullies and belts, 16,17 18 psi that I ran into belt trouble. If you would be happy with a modest 60% bump in your power, I think the Procharger will be more reliable than just about anything else under your hood. Which is why I also like the Procharger...it fits well under the hood. JS Quote Link to comment Share on other sites More sharing options...
