First Problem With Supercharger

[tbm34]

After a little over 18,000 miles I had my first SC problem. A heard some rattling coming from the main drive (serpentine) belt and could actually see the belt catching and jumping a bit. A thought that it had become misaligned, but actually the bearings on the idler pulley had prematurely worn. This comes with the SC and is used to adjust the tension of the belt as it winds through the system. It wasn’t a big set-back, only $85, but a bit disappointing for it to wear so early. I suppose stuff like this should be expected when you start messing with stock set-ups. I have not posted for a while, but as a reminder I’m running the TRD SC with the Unichip. This saved quite a bit of money by having to pay for the piggy-back ECU, and at the time I did it GM had still not released their version of the SC. Otherwise, it has been running like a champ, and I still get a kick out of driving it every day.

I remember you. I always thought that if I did not go turbo , I would have done something like you. If i remember right, you got the SC and the fifth injector stuff for around...1700.00, and then you had to pay for the unichip stuff for a few hundred...or something....very smart...plus you got a better tune than the TRD one or SPO one Boost is a great thing, and I am glad to hear another Vibe owner enjoying it, there are just a few of us it seems. It really changes how you view the car...it changes everything, puts the car in a different league
