Questions for the manual n54 owners

oh no. i can hear my car turbos spooling all the time. power still seems to be the same. you think its a leak?

Your car has down pipes so it will always make the spool up sound especially from idle. My wife hates it. I told her I can put the catted dps back in and she will loose power - she never complained again :roflol:

With modded cars its good to compare waistegate DC's. Variences at the same boost can identify leaks.

no my car just has Jb4. no dp. but i can hear the turbo on stock map and with no JB4. louder with map 5. this was after a major fix on the cylinder head. i used to only get this sound with DCI. was silent before the fix.

best i get it checked. i am worried now :mmm:

Pretty sure you've got the same noise as me. Do you get it under low throttle input as well, e.g. puttering along in 2nd gear, below or just in boost and it sounds almost siren like?

mine is the same sound I hear when I had DCI's. I loud "whooshing" noise.

as soon as the boost kicks in, low revs, high revs, whatever, I hear whoooosh. but the power is still there.
