For those of you who claimed that you noticed "jerking" on your supercharger, can you describe the symptom as detailed as possible and also, what was replaced to fix the problem?

s/c makes a chirping sound when the clutch engages.
Remedy = replace s/c clutch

Originally my chirped and had hard downships upon de-accelerating. Agree, s/c clutch replacement under warranty fixed both.

How do you guys get through the service people? All they tell me is that "everything in the car is electronic and the car is not throwing any codes/light"

from a dead stop..

put the trans is S mode.


use your right foot to press the brake.. release and use your right foot to press the gas pedal.

once the rpms start climbing you will notice a sligh hick up with a slight chirp.. Thats the jerk or chirp.

In some cars is very audible.. others not as much.

if you feel a hick up from 1st to 2nd while driving hard.. you have the S/C jerk.

I think I have the jerk, but not the chirp. Is this still abnormal ?

Get it a Women, then it will quit jerking..

My car does the chirp and 2 mb dealers say that it's normal.

TopGun32

to avoid the "jerk" during a stop light race.

apply brake with left foot, load the rpms with right foot to about past 1k Rpms.

This engages the clutch and the jerking will not be there (or atleast it should not be there)

The more mods you have, the more you probably will feel it.

its normal.

my car has both the jerk and belt slipping sound... i havn't tried to do anything in terms of fixing it... i don't drive very hard, so during normal acceleration you can feel a rather large "bump" and the belt making the screeching sound... it depends on how many people i have in the car/how fast i accelerate...

As far as I know it's the clutch making the sound not the belt. It looks like the clutch faces are both metal, and when they clamp together that's the noise you hear. Now I have heard what sounds like belt slippage if I do a decent burnout and then snap my foot off the throttle. Regardless, I've put 8,000+ miles on the car since I got it in May, and the sounds have not changed a bit, so I'm not worried. As long as it chirps, it's working, and that's all I care about.

i agree... i didnt know the noise wasn't the belt, however that was the best way i could describe what it sounds like... regardless, i agree with you that as long as it chirps i know it's working, and i've gotten used to it so it's nothing to worry about...
