It might be. You might want to see if the coupler in the middle is going bad.
If it is not leaking oil yet, then it might just be this coupler.
The most common and normal signs will be: * Oil leakage from the supercharger * Supercharger making a knocking noise * Lower or no boost pressure * Oil not present inside the supercharger
If your supercharger is an Eaton type supercharger and it is making noise that is an early indication that the supercharger might need a rebuild. A lot of times the noise is actually coming from a little coupler that is located in the inside of the supercharger. This coupler has 6 holes in it and over time these rounded holes will wear out and become an oval shape. Once it becomes oval shape the supercharger will start to make a rattle sound. If left untreated the rattle will lead to the bearings going bad and then the seals. You will then need to get a complete rebuilt done on the supercharger. The coupler is easy to replace. You basically have to take the supercharger noise off with the 6 bolts that holds it and then once the two ends pull a part the coupler will be sitting right there. Just slide the coupler off of the pins and replace it. Then slide the two ends together and bolt it back up. You will also need to refill the supercharger with oil.
Hey man what you going to have to do is change the couple ling in the supercharger, there is 3 holes that hold it in place and for what you say they have way to much play in them, that is where that noise comes from, the misfire comes from the supercharger not engaging so this will fix the problem and is very easy to change is a no brainier so good luck, here is the web site you can buy from www.zzperformance.com/grand_prix/index.php let me know how it goes.
It could be the supercharger snout itselft. I just replaced mine because it was making a sort of knocking noise. I started out just hearing it at start up and turning it off. Mine runs like a champ now along with a smaller pulley and an exhaust job.
When you can not figure out why your car makes a strange noise, you take it to a mechanic.
wheel bearing, gearbox or wind noise Supercharger?
In most cases the fuel pump will not make any noises at all. A fuel pump going bad will cause the engine to shut off unexpectedly.
supercharger coupler / bearings
Normally this is the bearings going bad.
No, it isn't normal for your cat to be drooling a lot lately and making a strange burp like noise. He may have eaten something that isn't agreeing with him and causing the strange behavior.
Could be the bearings/pulley. until you fix the issue you should remove the charger belt, so it doesn't get worse (blow the supercharger).
If your 88 CRX SI alternator belt is making a strange intermittent noise shortly after changing the alternator what's wrong, the belt tension could be off. Adjust the belt slightly.
