Jonel I had alredy found that link but the link to the supercharger noise leads to another Post, not to a video. I cant find the actual video.

 

nevermind I got it.

 

Okay my car has officially the same sound as Jonels car in the video, DOes this mean I have to replace my charger, or that I can get a rebuild kit and that will fix it.

 

I get those sounds too since I got the car back... Eeek. Not too happy about that one.

 

I think that’s a normal noise. Mine made it from day one.
I did not bother trying to get it replaced.

 

I can't hear the clip here, but it's probably that coupler in the supercharger making the noise. I would keep and eye out though. Did you try the belt removal trick yet?

 

Here's my SC Noise. **Please RightClick and Save-Target-As** 24 MB Vid. It doesn't sound healthy to me at all, but its always sounded like that and its running great. Did a 0-60 today and it was right at the 6 seconds mark.

 

Just did quarter mile run in my interceptor and still knocked a 13.2 quarter mile run. So it hasnt affected my performance at all. Im gonna do the belt trick next 2k5.

 

E to the X, My sound is like yours.

 

My cars sounded like that for a long time. Hasn't hurt anything as far as i can tell.

Off topic...you ever get to ship those headlights?

 

Yes I did, On friday, The tracking number is in the car, I have to get it, but im lazy, Ill get it when I go take off the belt and PM you it.

But by the way, Dont worry guys! Ill find a solution to this DREADED SUPERCHARGER NOISE!!!

 

Awesome dude thanks. Yeah I hope you figure it out. I don't feel like pulling off the eblt today...its cold out!

 

Timing chain tensioner went south on my car = new motor from GM.
just got it back

 

Did you ask them if they used a better tensioner?????

 

No, because if it happens again, I'll be closer to a 30 day lemon. I'll get the new car and trade it in on something not GM.

I know this has been said before, but GM customer service is so poor, I don't want this car anymore.

 

Update, Took the car in to the dealer, For some reason the Tensioner of the timing chain went bad. The chain was hitting the top of the cam gear. They ordered a new tensioner and a new chain. Everything will be covered under warranty. Thanks to all of you who have shined in this thread to make my life easier.
Later guys.

 

I figured that would be it....
congrats on getting the warranty repair.... I"ve heard of a few doing that

 

Likey because it is crap

 

So yeah those of you who have the supercharger alike sound. Check you car, it could be the timing chain. Thats if the sound is loud enough to hear when you are driving the car.

 

i have an 07' with 1200miles, and noticed it at idle the other night, sounds like a fairly loud rapping/knocking coming from the timing chain cover towards the back, but if its cold itll go away, sometimes its loud and sometimes its quiet depending on how i am driving the car..goin to the dealer next weekend. and btw i had the supercharger noise since the day i picked mine up!
p.s. car is stock w/ a KNN CAI

 

Thank god you got everything fixed man

 

Okay my mechanic says that what could have caused the belt to do this was the rev limiter at 7200 rpm. Too high for the system. Now those who have the noise in the hot only im sure the belt kind of gets looser when its hot and gets contracted when its cold. So I would check that immediatly meaning the Tensioner has some play already.

 

I didnt think it would end up being the SC . Glad ya nipped it before nething catastrophic happened , and even more cool the dealer didnt hussle u on the warrany . Cool deal

 

Belt or chain?
