    ***Please be advised... I own the car...don't work on it... will if I have to but then it might explode***

    Hello everybody!

    What I wanted to know is:

    should replace the nosecone/snout unit or rebuild it. My
    car has almost 160k miles and the nose cone sounds awful. I just got the O2
    senor replaced as well as the plugs and wires because the engine light came on
    and also had a misfire reading. It's still doing a spazzy reving type
    noise when it's in park and also at times when I'm driving and have to slow down
    to turn a corner...it's even cut off a couple of times recently. My mechanic says the
    rpms on the charger are hire than the regular engine and causing it to bog down
    ( he said like using a lawn mower to cut the grass and the grass is too tall).
    He says the belt cant catch it right ( or something) The tensioner on that belt is loose
    as well but he says that's not the big issue.
    He says replace it but he's not familiar with this part in particular... no one
    is it seems around here...except for a lil boy who has one, works on and races his and
    said it's the bearings and maybe a spindle (?) turned from the sound it makes but since I
    won't party with him he's a no show (go figure). Anyway I don't know what to
    do... I don't know how to work on cars. I've seen rebuilt snout/nosecones online but I don't know.
    Any and all help or information would be greatly appreciated. I also looked at the kits on rollingperformance.com
    but I don't know what to do with them. I just need someone to tell me so I can tell the mechanic and keep it moving.
    Oh and if anyone knows anyone in southwest virginia that can fix it for me please tell 'em holla at me! Thanks!

    I bet if you removed the belt from the supercharger and you grabbed the superchargers pulley and move it back and forth quickly you would feel alot of slack and that where the rocks in a bucket sound comes from.

    The coupler is a just plastic and over time it wears out and makes that noise.


    As for the car stalling/dying, it has nothing to do with the supercharger. Yes the supercharger does spin faster than the engine rpm because the pulley is 1/4th the size of the BIG pulley called the harmonic balancers that spins both belts at the same time. Its purpose is to spin faster and create boost for the car.


    Does the car just die out of no where and you are able to start it up and keep going???

    Do the rpms drop to zero, then the car dies a short time later?

    If so that is a common crank sensor issue.

    Thank you so very very much! I have forwarded the information to my "peeps" to see what they can come up with... so far I gotta give you props because the know it all says ooohhh... that makes since that sounds about right so kudos to you!

    What has happened when she cuts off is I'm driving slow down to go around a curve or turn and the idle spazzing starts jumping from 0 to over 1 rpms then on the down spike she dies... I throw it in park and begin to start. It's taken a couple of tries and usually success comes from me listening to the turn over and hitting the gas hard just right then I can go. It's not the map sensor ( God knows I know about those!).

    I still think the snout needs servicing... I am positive no one serviced it before I got it and it still sounds like "poo" I do know the tensioner is loose for the supercharger belt but of course I'm told to just drive it... it's ok so...

    But thanks again and I will see what I can do from here. If you have any other info please share!

    you may need a new coupler for the super charger, its a easy fix. heres a vid, so you can see what it does.



    the rpm surging could be a vac leak, take some carb cleaner, spray it around the engine while its idling. if the idle jumps up, you found your leak. the T's like to crack, as well as some of the vac lines with a hard curve in them.

    if the tensioner is bouncing a lot, change it before it breaks, if it breaks, you'l need a new belt as well as a new tensioner.
