I am not really convinced it is the coupler then. The pulley will spin by hand, but not what I would call 'play' in it. It is not like I can spin it a certain amount before it catches. It feels pretty solid, but I have not felt one that is bad to compare with. What else could be wrong, and how do I check the rest of it? I just went and started it up with the belt still removed, and it kind of sounds like maybe grumbling still in the middle of the supercharger area. It does seem a little less noticeable than when the belt was on, but the noise did not go entirely away.
As for the elbows, only the top one is leaking, right where it enters the intake manifold. I noticed that if it is just sitting there it will seep (not really a leak, more of a seep), but it seems that I can push it in toward the intake ever so slightly, and when pushed in it does not seep. It looks like the angles are all right, but it is almost like it is not long enough. Anyone know if they are not as long as the stock elbows, or anything else I can check as far as lining them up right? I put them in the bracket first, then pressed that straight on. They slid right in, but it seems that they just don't go in far enough.
