There is a very strange kind of loud sound coming from one of my air filters. I took it for a drive and i get practically no power and little boost until 4500. Did i blow my primary turbo?

 

Boost leak? Airpump moo? What kind of a noise are you hearing? Nobody can really help you with this much info...

 

its just one of the intake filters makes a loud deep sound, like tra, tra, tra, tra it actually sounds kind of nice but its never happened befoe. And like i said now i only get power after 4,500 rpm.

 

well since both turbos contribute boost after 4500 rpms, i doubt you "blew" your primary. Could be a vacuum hose that popped off?

 

check the MAF first, it's notorious for having its hose pop off, then look to the other hoses. I would bet that is what it is.

 

Our cars done have mass air flow sensors...You must be reffering to the map sensor? I have never heard of this causing a noise though. Just running poor, especially when on boost.

If it were me, I would start out by checking all of the vac lines. Good luck.

 

checked all vaccum lines. i tie wraped all of them.
