as someone mentioned earlier maybe bearings or seals. But i had a clatter/rattle sound that i ONLY heard when from about 1-2k rpms when putting the car in gear and a bit of a clatter/grind @ idle, turned out one of my pulleys had gotten lose. Dont really know how, maybe wasnt tightened all the way, maybe just vibrated a bit lose, either way, i went and cranked down all the bolts that i could get to that hold pulleys in place and problem was solved.

here is a video of what mine sounds like. The video sounds worse than it does in person. I started it for people that have owned or heard vortechs and they say its normal but mine sounds nothing like that video

 

^ mine sounds like that.

 

but a little quieter

 

Ya mine doesnt sound that loud in person. For some reason my camera didnt pick up any exhaust and picked up alot of chatter.

 

just spoke to vortec and they said that the v-2 should have some "backlash" of the gears at idle

 

Consider that our cars have small, high-rpm engines as compared to the vehicles this supercharger typically goes on. The impeller spins at a lower rpm at idle and having little load (air to move), the gear drive inside the unit tends to rattle. As long as it goes away at higher rpms then there is no problem. If you are running a smaller pulley, making the supercharger run faster, you may not have this issue, or it will be less.

 

mine sounded similar, It needed to be serviced

 

backlash is what it sounds like thanks for confirming s2kjb. I have half the people telling me its normal half sayings its not. Now was their a model for the s besides the v-2? I have the v-2 on mine I am wondering if these quiet ones are a different model?

 

i think im going to pull it off and get it checked out, wish i knew how to do it the parts only cost about 50 bucks. it would be a good piece of mind too.


anyone trying replacing the bearings/seals themselves before?
