does anyone know where this sound is coming from, it sounds either its sucking air or hissing sound that seems to get loud when ever i press on the gas. i can hear it louder if i was driving next to a car on the passenger side but nothing on the driver side. i made a video of it on idle.

p.s this is all stock except for a bbk catted x pipe

the sound is all in the background, not the ticking sound from the belt but the constant hissing or sucking sound. it was not there before kinda of annoying.

Did you put the stock intake back on or are you still using the Steeda CAI?

its all stock, i have the stock intake in there. i thought at first is was the steeda cai that was making that noise but when i put everything in stock it's still there.

Maybe a vacuum leak?
Check that all the intake clamps are tight. And the pcv lines.

i'm still with in my warranty. can the shop take car of that?

danzcool

Yeah, they can do it, it helps if you can point out the problem area, because sometimes they just come back and say it's normal.

thanks brother, i wanted to try to fix it my self and I've seen people do a vacuum leak test on youtube using carburetor or brake cleaner and some uses smoke method to find the leak. i want to go with the smoke method since it seem to be the safest way, but my problem is i don't know where to find the right vacuum hose to begin with.

Spray all of the vacuum hoses leading to the intake manifold/supercharger and listen for a change in the idle.

what are the chances that my car would caught on fire by doing this? even if its just warm.

A safer thing you could try is spraying water (with a mist bottle) over the vacuum hoses and connections and listening for the water to be sucked in.
