So, my supercharger is rattling, and I've been told that it may be the rotors in the blower part of the supercharger because it appears that the nose has already been replaced in the past. However, I know that the couplers are known to go out more than once, and it is a lot cheaper to replace the coupler than the whole thing, so I want to try to do that first. My options are a Dorman brand from Amazon for $12, a Eaton Brand for $15, or a ZZP Performance for $30. The ZZP Performance is apparently designed to be stronger, but I was wondering if anyone knew if it is worth the extra money. Does anyone have experience with this? It may also be helpful to know that I'm pretty sure it has the stock pulley and no engine mods that I know of, so I'm not sure if it would need the stronger coupler. I just don't want to replace it with a cheaper one and have it go out again if putting in a stronger one would prevent it from going out again. Also, does anyone have any tips for this job? I'm at school in Arkansas and there aren't as many supercharged cars here as there are in Minnesota, so I'm not sure anyone around here would have the experience to help me. So I want to be as knowlegeable as possible even though I will have to have someone at least help me lift stuff since I'm a girl with weak arms. Thanks for any tips you can give me!
