is there anyone in or around STL that can help me figure out why my car is making a weird sound? I dont know how to explain it therefor I need someone to look or listen that knows what theyre doing. thanks

its coming from the injector/supercharger area

 

if its a rotating or pulsing noise its either just injector pulse or the rotors in the s/c turning.. otherwise it might be the coupler for the s/c snout. its not much help but those are a few things it could be that are common

 

i already changed the coupler, i think i just worry too much but i want an opinion that doesn't cost like 100 from the dealership and plus the dealership doesn't know what they're talking about most of the time

 

Have any way of making a Vid? Do you come to st.louis often? Or are you coming here? One of us could look at it for you, there are a couple guys around the area that know the LSJ very well.
