Just trying to see if there is any other similar stories out there. I put my Vortech self-oiled V3 on my C6 last year. When I first started the car up, the supercharger sounded like it had a thrown bearing or something, but was told that it was normal. It worked fine, so I never questioned it.

I usually do my own work, until I was going to do a radiator flush. I had no way of properly disposing of the fluid, so I took it down the street for a local mechanic to do the flush. At that point, he told me that the supercharger was shot. Said that is is supposed to be quiet until you get on it.

It sounds like it did the day I put it on the car, and the local mechanic has no experience with the V3 so that is why I am asking. What does your V3 sound like at idle?

Thanks!

Typical sound of the V3si. I spoke with several people including Vortech. The noise you are hearing is gear lash. Once you bring up the rpm that will smooth out. At idle the flow is not steady through the supercharger due to pulsations through the intake. The slop in the gears causes it to rattle. Dont worry about it unless it makes the rattle noise up in the rpm band. To be on the safe side it is very easy to check the oil level. Don't confuse this sound with the gear whine it will also make. If you have any more concerns I recommend you call Vortech csutomer service. They were very helpful.

Thanks! I will call them and it is good to know that is normal.

Mine sounds sloppy at idle as well. It smooths out at any RPM increase above idle.

My V2 T-trim is kinda noisy at idle as well. Not as bad as a Procharger but quite a bit louder than I thought it would be. As RPM's pick up a bit it smooths out to a nice smooth whistle that we all love to hear. Tell the 'mech' not to worry about the sound and just concentrate on a good flush and make sure he gets all the air out of the system.

I have never heard a silent Vortech supercharger. I had a V2 SQ on one of my Mustangs and it had gear chatter at idle. Perfectly normal and not a problem.

can any one offer up a sound/video clip?

LOL, this post made me chuckle. I thought mine was shot too after one particularly noisey cold start up, especially when I popped the hood and there was oil on the brackets. Turns out the oil was from my breather and that noise you are hearing is 100% normal.

I even called A&A when I thought a bearing was shot, and they genuinely seemed pretty shocked, saying they have not had a single V3 come back due to bearing failure.

Remember to change your oil every 7,000 miles.

I concur... I have the self-lubed v3, SI trim on my 2008 coupe. It sounds great at RPM...and even smooth at idle... I have about 10k miles on it since new and installed. It sounds SO WICKED when i get into it...and at idle it just purrs !!! like a cat. a little whistle...but, not gear noises though.

Here's a V-3 on a Mustang. Should sound the same on any car. Blower sound starts at :45 mark. Rest of the video is kinda

See I thought the same, but when giving it some gas it keeps the rattle going, thought maybe it was seals and bearing, but when feeling pulley and spool the pulley has some play so that leads me to think it’s a problem with the gears? any explanation on what i should do or what the issue is??

Wow -Blast from the past thread!

NE way, I mentioned mine had chatter at idle, I replaced the harmonic balancer on that car to an SFI rated piece and all that noise went away. I am guessing a new OE balancer would have netted same results. That car is gone now. I would not install a new SC without replacing the balancer at the same time, unless the car is almost new.
