Ljavy17 and I both have a wierd supercharger noise coming from our blowers. Ljavy17's blower makes the noise only before it's warmed up then everything is fine. Mine made a wierd noise when i was boosting zero kinda of like a buzzing noise. ANy of you guys have an idea of what it could be?

 

wow i just had this problem i think its if u rev it up in cold weather while its cold once my car warmed up it was fine

 

ya i think maybe the cold is the problem with the noise?

 

our superchargers are not quiet by any means..if your worried take it to your dealer

 

i had this promblem.... after me taking it to the shop like 5times they finally reliezed i need a new blower
all warrantied

 

do they warranty blowers that have a 2.6 pulley on them? Probably a stupid question lol

 

No they dont. So put you stock pully back on befor you take the car and strip any and all mods off the thing first. They look for any reason they can to charge you for crap they should be covering.

Later

 

yeah... any mods.. = voided warranty... dealerships suck man..

aslong as you're still making full boost I"m sure its alright.. just don't be gettin on it til it's warmed up

 

alright thanks guys i was boosting 20psi last night and the car seemed normal so hope this isnt anything to serious.

 

it's normal, especially if you live where it's really cold and run it after only warming it up for 5 mins....mine has had that noise since last winter and its the same this winter, only when its really freezing so it's nothing major. The dealership checked out my car last year too just to make sure it wasn't anything major and they said it's not and it's normal, most cobalts in the cold will make that noise once it runs after not properly warmed up.

 

the noise sounded like the rotors in the blower didnt have enough oil or something

 

Yea, get that here too. It's fine.

 

ok good cause we thought we were the only ones lol

 

Mine id doing it also, i havent driven my car in a long time also, is a grinding sqeeking noise in mine, and after you rev up the car it goes away, or it wil still do it like every minute or so, iam just going to get the bearing re-greased.

 

thats the same thing mine does ^

 

Mine has made the same noise since day one. It's normal.

 

We had a few threads on this. See my Video:

Mine is more aggressive than that, its that grinding noise plus some sqeeking, if you rev it up it wwill stop, on;y does it at idle, doesnt do it all the time at idle, every minute or so, i think the bearings need grease.

 

theres a bad bearing set i had 3 replaced

 

How much did it cost you?

 

That is soooo true!!

 

Under warranty everytime i would open the hood it sounded like rocks in a tumbler and when i was around other ss/sc's and theres was quiet. well took it in and first time they replaced the sc then it was doing it again and i went back and they repalced the sc again. well the damn thing was still making a noise the guy said he would take it home and monitor it well we came to the conclusion its the bearings so we replaced the bearing set. unfortuinatly its still making the noise............. so im goig to take it back and see if its something else? maybe in the engine or somehting else. ill have to bring it in when i get back from texas

there is apperently a different bearing set between the 05 and o6 to the 07 does anyone know if the tvs is being used by chevy yet?

 

Well i doubt they will warranty mine.

 

I just started with another noise today. When its cold it makes a noise then it goes away. and today, now when I drive it hard it makes a low noise like metal hitting metal. Only does it under full boost though. Is it time to rebuild yet.
