vortech s-trim...how loud should it be?

[95CobraMike]

i recently bought a 94 cobra that is supercharged by a vortech s-trim supercharger. when idling at a complete stop that thing screams! but once i give it a little gas, it quiets down a whole lot, you can barley hear it...are the bearings going out in it? or is that just the way it is suposto sound?
thanks

nope... thats the way its supposed to sound. Nice isnt it?

 

[95CobraMike]

i thought it was nice, but people keep coming up to me and asking if i have a bearing going out, and i reply "no, thats the way it is supposed to sound...i think..."

S-trim's have straight gut gears, the howling at idle is normal. If you want something quieter, change the head unit to an SQ.

So they really do squeal?

So they really do squeal?

yes and its pretty damn loud too. I love the way the S trim sounds at idle

 

[4Jenna]

I don't belive it is a squeal...you guys are kidding right. Why would you want a squealing sound?
Maybe u do have a bearing of some sort failing?

Can you hear the SQ? I was thinking of getting one or the other, I wanted to hear it, but not quite as loud as the S-Trim. That bad boy is loud!

95CobraMike,

There's a video where you can listen and see if yours sounds like this.

It's an SC Trim

My brother's S-trim on his '90 LX doesn't squeal -- it has a gear whine, sounds like a low-pitched whistle at idle. Anything above 900 RPM or so and it changes to a turbine whine (much, much higher pitch and much quieter). And with any throttle the engine drowns out the blower altogether .

Sounds like that car is having bearing failure also?
Must be common on Vortech cars.

The SQ is a whole bunch quieter -- you can still hear it, but it's a high pitch turbine kind of sound, very pleasant to the ears. The SC in that video sounds exactly like my brother's S-trim.

No, that's normal, an S-trim sounds just like that from the moment you pull it out of the box. Straight cut gears . I could never do that on my daily driver, it sounds kinda cool but I think it would get old after awhile.

Maybe it REALLY IS the blinker Fluid?

does it sound more like a whine or a whissle or is it an actual squeel.
