In the last few weeks my SC has been a bit louder than normal. The performance feels the same but something doesn;t seem right. Dont get mew wrong, I love the sound, but it means something is different and not working correctly. What should I look for to see where this is coming from? It is a boost leak, vacuum leak, valve cover leak? I do get the smoke from the hood vent every now and then so I think my valve cover gasket needs to be replaced but it has been that way for a year now. Let me know!

Thanks brothers!

 

could it just be that time of the month?

 

Yes, col dense air will make more power and more whine,,,, so will adding bigger pulley and other mods.

 

But it happens all the time no matter the temp outside

 

Is your airbox correctly bolted up and securely plugged into your TB? If so then open them up to make sure your filters are still intact and are sealing the airbox properly

 

alternator whine?

 

I thought that may be it AWOL, how do I check it? I am pretty sure its the SC cuz if i push hit the gas it sounds like boost but i could be wrong.

 

record a video, upload it. make sure no music is playing

 

Take less than 1 minute and remove your S/C belt. Drive it nicely around for a bit and see if the noise is gone. Then put your belt back on

 

This.
