Need help with a squeak!

03_StangGuy · September 17th, 2008, 11:03 AM

I got my can running with the novi 2000 last week and had it tuned on saturday. Thursday, friday and saturday it was fine, then on sunday I get this squeak, its real consistant, like a constant chirp from idle through the rpm. As the car heats up it goes away. Far as I can tell all the pulleys are tight. It seems to be coming from the area of the altenator/right idler pulley. Im pretty sure and praying its not comin from the supercharger. It doesnt really sounds like a squeak from belt slippage. Theres is a build up of belt dust if that matters. So any ideas what it could be?

no one?

97S281 · September 17th, 2008, 01:51 PM

Yeah, don't worry. It's just the hamster inside the supercharger running faster when you give it some gas!!

03_StangGuy · September 17th, 2008, 02:03 PM

Nah its not the s/c whine, thats there but theres also another distinct squeakin.

C MY 4D · September 17th, 2008, 02:06 PM

All of the belt slippage has probably destroyed the belt.

MustangMatt96GT · September 17th, 2008, 02:06 PM

pulley is not lined up? Worn out belt?

03_StangGuy · September 17th, 2008, 02:08 PM

They s/c pulley did look off slightly (less than an 1/8 inch) but the shim is in there and the belt looks good far as i can tell.

MustangMatt96GT · September 17th, 2008, 02:21 PM

take the shim out, or put another in to line it up

03_StangGuy · September 17th, 2008, 02:25 PM

The only shim i got was like a 1/4 ich thick and i dont have any others. Ill have to check if the paxton blowers are shimmed

C MY 4D · September 17th, 2008, 02:58 PM

Shave the shim down with a grinder..... But more than likely something else is shoving it out. I haven't installed a Novi but I wonder if the nub on the timing cover has to be shaved off like on a vortech system.

03_StangGuy · September 17th, 2008, 03:14 PM

well its not brand new so it should have been done but Ill take a look. I know belt slip is an issue wit a blower, do they need to be replaced anymore than with out a blower? The belt I have isnt new but its still in decent shape.

would a misaligned belt cause a squeak?

yes very much so, as would a worn out belt, and one that is not tight enough.

03_StangGuy · September 17th, 2008, 04:46 PM

Well the belt looks alright, and is def tight. Ill have to look into the pulley. I wish it werent such a PITA to change the belt.

My car isn't supercharged but I had this same problem a couple weeks ago. It ended up being the tensioner going bad. Maybe that's it?

03_StangGuy · September 17th, 2008, 04:54 PM

did the squeak lessen when the car warmed up too?

Sometimes. Look at the tensioner and see if it's twitching at all when you give it gas.
