when i accelerate past 3200 rpm, i can here the leek. i checked the boots on the fmic and they are fine. the sound did come after i went fmic. i had the stock bov and recently changed it with an APS bov. what could it be coming from.
Its more than likely not a leak rather the increased air flow from your FMIC. Wooooooooooooooooooooooooosssssh!
i could hear a pretty loud whistling sound that kinda sounded like a supercharger after i changed to a greddy rs bov..i uninstalled it and it fixed the problem and i put the bov back on a few months later and didnt have the problem..i dont know anything about tmic's but i would check the bov if i were you
Did this happen before or after you did the bov? I know the HKS SSQ sometimes sounds like a supercharger on spool up depending which tip you have. Otherwise I would say its the belts
no it happened after i went with a fmic. when i went for a test drive after installing it. it may be from increased airflow? would anybody recommend upgrading my uppipe, to solve the problem?
No, no y pipe with a fmic. Does it sound really loud? Like a squirrel on helium getting squeezed by the world's strongest man? If so then its a leak around or from the bov more than likely.
Lol, I totally misread his post and thought he was talking about adding a bigger y pipe. My mistake. Just check for leaks and if everything is okay, just get used to the sound.
Not true, I had a BPV that was leaking that still made boost. You could hear the turbo working like it should be at full boost, then like a light switch full boost would come on. I swaped out the BPV and it fixed the problem.
it cant be from the bov i just changed it to an aps with a gasket. no i gained power, its not loud, i guess im going to double check the boots. or just get use to it. plus i got it to were its a 240 killer now. lol.
I use 2 gaskets on the bov when I do mine. It helped seal better for some reason. I had a similar issue and using 2 NEW gaskets made the sound go away. The other thing is you will hear your turbo more with a bar and plate intercooler....not sure if it is the design, but I can hear the turbo spooling much more now than when I had the stock intercooler.
x2 man that hks ss had me goin...i thought i had a big ass leak, but it sure does sound sweeeeeeet. It does it loudest with purple insert. yea you prbly just hearing your turbo spool up
You can disagree all you want. I took logs with the leaky BPV and the one that is on the car now. Just changing BPV netted me 500RPM before I had full boost. Can you explain what else would ahve caused this but a leaky BPV? All hoses were checked for leaks and none were found.
