The Supercharger on my cobalt has made a slight grinding noise since I bought it new. It now has around 3800 miles on it and the grinding noise from the supercharger has got to a point that you can hear it without popping the hood now. Is this normal? This car is my first time messing with superchargers,(I have always worked with turbo's) so I don't know what to expect with it. Any input would be helpful.

 

Mines the same way. Until I start losing boost or performance I'm not worrying about it. I just got told today by an ASE mechanic that it's a completely normal noise. These are noisy blowers or so I'm told.

 

Glad to see I'm not the only one, I have wanted to listen to another cobalt ss/sc at idle but I am the only one in my area

 

Here's a vid of one Jonell took just for this purpose.

This is the best forum... ever.

 

Uhhh....That's NOT normal. There have been more than a few people here who have had blowers replaced under warrenty due to bearings going out. I'd take it to the dealer and have them check it out b/c if you get metal shavings into your motor....that's def. not a good thing.

Watching vid now...

 

I appreciate it. Another quick question, is it normal for the car to backfire with stock exaust?

 

So then why hasn't Jonnel took his in? His hasn't busted apart at the seems or blown his motor. Mine is just fine, I'm not loosing boost or anything.

 

I can't say as I've had that problem.

 

I can't get that video to load

 

right click and save target as It's a pretty big file.

 

I can't even get to the next link after the one you gave me

 

Mine pops between first and second sometimes. i wouldn't worry too much about it as long as it doesn't get too bad

 

You're going to the thread I posted and then you're right clicking on the part that says "Supercharger noise on my 06"? That's the link to the video, just right click and save target as. If you're not getting to the thread I have no idea what it would be.

 

That worked, thanx. That is exactly like mine sounds

 

Mine will do it when I shift and every once in a while I will get a pretty good one when I down shift.

 

If I run into any problems I'll post it up on that thread, but I'm not losing boost and someone with alot more know how than me told me it was completely normal.

 

yea i wouldn't worry to much about it. if you get your car tuned they may be able to help with that by changing the timing alittle but it's really no biggie

 

To be honest, the louder that noise gets the better my car runs(Faster). But it is sweared by many that your car will run the best right before it goes

 

Im waiting for the vid to get done loading...hopefully it sounds like mine. This has been my main concern with the car since i got it.

 

Let us know if that is what yours sounds like

 

Bump^

 

Mine sounds exactly like it...phewww...and almost 4000 miles later i know im not the only one lol
