I have the TRD Supercharger put in and now about a little over a month and a half there is this weird sound coming from the pulley area. It sound like a alternating vibration (sounds like a damn frog croak) every other second. Now it goes away a little bit when my car warms up but ITS LOUD AS Heck its barely warming up. I asked some Techs here what it could be and they said they didn't see anything wrong at all. I wanted to know if I'm the only one because if so, I can take care of it through the warranty. Any replies or info will help. Thanks

 

I would try asking over in the tC Force induction forum.
I do not know of many ppl here with a supercharger on their Scion..


Shush Chad.. ya ya I know.

 

I would call ZPI and speak to Kenny or one of his guys, they have several S/C out and may know the answer.

Well just to let everyone know I still have that wierd noise coming from the crank area on the TRD Supercharger. Any supercharged TC owners experience this sound yet. Kind of sounds like a frog croak or the "Predator Sound" every other second. Getting annoyed and wanna know before I change the pulley's. Any info will help.

 

go to the dealer and ask them if its a loose belt or pulleys. i 'wouldnt think it was the baerings in the pulleys but check anyway
