real loud spool?!
well i have been trying to figure out why car sounds like its spooling a HUGE turbo. when i pressure test the piping i get no sound at all, it only happens when in load wont do it if its in neutral and i rev it. is there anything else i can do to try to make the sound? can it just be the turbo going ouit? i have no shaft play at all

Sounds like your turbo is seized.

Smartass! There, I called you that again!

Seriously, what turbo are you running? Stock? No exhaust leaks?

Maybe you're paying too much attention to the sound

its a stock det setup. boost gauge reads 7psi but its just extremly loud. what would be the best way to check for exhaust leaks?

If its very very very loud it is probably a boost leak. My t-25 on 14psi spools pretty loudly but thats a higher psi so it should. Can you take a video?

are you sure the bov is not leaking?

my guess is your turbo gasket is on its way out

if the bov was leaking wouldnt it make the same sound when i pressure test it? tested it at 25ish psi and didnt make a sound.

If you removed the recirc tube or run a open bov you would hear a leak from the bov with a pressure test. That's if the bov is the issue.
