If i put on a pulley that will give me about 10-15 hp will this reduce my fuel economy a lot? Also will it reduce the logetivitly of the supercharger, not that this is a big deal to me because i can rebuild it. And i guess a smaller pulley will mean i have to run premium all the time. I do run mid grade gas sometimes, but only when my foot isn't heavy. I never give stomp on it or anything unless there is premium. And i have never had knock so far. To the members who put on differant pulleys, what kind of differances did you notice in the car? Thanks.
I don't think you can get a pulley that will give you that little, unless you have one custom made. The typical size for yours is the 92/93 stock size. 2.5". Your fuel economy won't suffer with it unless you lead-foot it everywhere. The Supercharger will outlive your entire drivetrain if properly cared for. However, there are exceptions to this rule (I have yet to see a 'true' failure of a SC on any car here).
Don't ever run mid-grade gas. This is worse for your engine than a smaller pulley would be.
