Well I took my car in for some unrelated things, but I asked my service guy to have them look at the supercharger and find out what the rattling sound was. Well it turns out that the blades inside were loose, so they are going to replace the charger with a brand new one. He said it's good that they caught it cause much longer and it would have sent metal shavings into the engine, because the rotors would have started to hit each other. So I get to drive a gold HHR in the meantime, which I think is actually a pretty cool car. I just hope I can get it back before the car show on Saturday.

 

i have that similar problem..theres like this weird noise coming from the supercharger...

 

Oh nice. So now what...we get to add faulty blowers to the list of things that go wrong on these now?

 

take it in and get yourself a new Supercharger!!

 

Holy Hell> Mine Is Rattling To. But i have the Intense kit but yeah i think Rattling explains the noise well. that is not good.

 

What I was wondering if they would give me the old one, I'd rebuild it and sell it.

 

Good thing you caught it when you did.

I hate to break it to you, but I doubt you will have the car back in time. Everything I have had to have ordered for mine takes over a week to come in. I hope I'm wrong.

What exactly was the sound like? Mine sometimes starts to sound like a Duramax. Not sure if it's the vavletrain or what. It comes and goes, and normally doesn't last long enough for me to get home and pop the hood.

 

You should ask. Then send it out to get rebuilt then ported and polished.

 

they would half to keep it...they send the old one back to get fixed

 

The rattling was constant at idle, and I guess it did sound like a Duramax, but it was always there, and I could actually feel in if I put my hand on the charger

 

i dont know how to explain mine but its like putting dice in a cup and shaking it

 

that sucks, I'll ask anyway...

 

so was it as simple as. Hey i need a new Supercharger. or did they try and knock you around. because i may check into it. definitely doesnt sound good

 

mine sounds like a bad wheel bearing at idle i was told its normal :S:S andthat was before i installed the gm stage 2... if anyone els has had theres replaced for this let me know!

 

Yet another thing to make me glad I didn't get a SS/SC

 

No, all I said was: "hey, can you also check out the supercharger, there's a rattling sound." And I got a call back saying "We looked at the charger, and we're going to have to replace it"

 

Mine only happens at idle also, but not constant. I'll have to keep an eye/ear on it.

BTW on a roots blower the blades are supposed to rub together slightly. That is how they move the air, and also why they are notorious of getting really hot intake temps.

 

Oh yea, you're right.......IDK, That's what the tech said, maybe he was just simplifying it for me

 

ruh roh, guess im not the only one with this noise

 

I just sold my GTP to get a SS SC.

Anyway. A common thing with the Eaton superchargers that causes noise is the coupler. It is a pretty inexpensive piece (around $30) and is easy to replace.
You just have to take the SC snout off. Of course if its under warranty, just take it in.

 

not sure if this is related but mine doesn't make noise like rattles but it certainly gets really freaking hot. I thought it was suppose to be cool to the touch?

 

No they normally get really hot. That's why people call them Heatons.

 

When the car was new and I checked every so often it was never that hot even before the intake. It's like putting my hand on a hot skillet. Before it was always cool to the touch.. wear perhaps cause this?

 

I'm not sure. The blades actually rub on the outer housing and each other to move the air. They are supposed to have an epoxy/teflon coating on them to help increase efficiency and decrease heat. Maybe it wore thin or something.

 

Mine was hot as hell when I went to the track last weekend. Of course mine was broken apparently. Maybe that's why I only ran a 15.1, that or cause it was 100 fricken degrees out.
