Strung together some of the sounds coming from the turbos in an audio clip
Was in peak hour traffic so was not able to go WOT, mostly just trying to capture the sounds passing the morning traffic where I could
Some are the tial blow off valve but the woodland creature hooting sounds WTF? turbo flutter, loose intake pipe sucking air?

[Scotty89]

mate thats fucking hilarious, I've never heard those sounds ever before.

[Scotty89]

That's not flutter though, flutter has a chopping sound to it. It's like it wants to flutter, but won't.

Definitely small chipmunks and other woodlands creatures bouncing around in there!

That sound is just flutter. My mate's GTR sounds exactly like that. If the BOV has preload adjustment, back it right off all the way. If the flutter is still there, you can embrace it and love it as I would or buy a softer spring for the BOV/DV and that'll do the trick.

I'm thinking its not a sound I wanna embrace.
Thanks for the tip Bradster

Meanwhile ill send a link to Rob see if he can confirm its not something more serious like an ass-about turbine

[bradsm87]

The reason it doesn't happen with stock turbos is the stock turbos' surge line is a lot lower in airflow. Because stock turbo compressor wheels are much smaller and spin much faster, they don't surge in the same situation like bigger slower turbos do.

[Scotty89]

You should patent that setup.

Sockets secret mating call.

[enis1995]

its the vargas inlets and the rb turbos that produce that sound,

[tawfeeqh]

hopefully the sound reduces after you adjust the spring in your dv/ blow-off . Reminds me of the old VL turbos running the RB30s. Probably not the sound you want for a BM

[DR-JEKL]

great to hear you got the rb's in!

This guy had issues also with vtt inlets and tial bov

That would annoy the shit outta me!!!

[Brule]

Sounds like the turbos are pushing a bit of air so intercooler pipes must be good.

Something's up with your bov. Try another spring and see how it sounds.

Check front and rear inlet to turbo snout with a torch you can see rear from your wheel well and front is easily visible
From vacuum canisters.

If you cant see anything take it back to your mechanic

Thanks DRJ both you are Brule are on the right track. Is either a loose connection or the BOV as described in the thread. Will be back at Active getting hub fixed so will check connections there and see if if sonething can be done with the BOV

Thanks Brule I'll do that mate. Seems to be a common problem with turbo and inlet upgrade combo

[Boganian Rubes]

First 5 seconds got me ahahahahahahahahahahaha



hahahahahahahahahaha

PUT A DUCK CALL ON THE BOV
lmaoooo
Dude the guys you'll race will all die from crashes due to hysterical laughter, you could be charged with manslaughter

this just got serious

Duck call on the BOV great idea that would make it so much better lol. Seriously I have to get this fixed asap there is nothing baller about the way it sounds atm

[Socket]

Hey Vince on a totally different topic.. do you want to bore out my nipple?

[Socket]

Let me put it another way, I need some help with my nipple and vac reg line to the BOVs

See fix below

UPDATE: I removed the manifold and cut off the stock nipple and replaced it with a 1/4" brass hose barb. I then ran a short 1/4" I.D. line to the BOV instead of a 3.5mm line I was using.

The BOV is WAY more responsive now. Because it is more responsive, this moaning noise from the VTT inlets is now reduced by 90% or so. It still moans slightly at low boost, but not at all at high boost.

I think the moaning has something to do with the BOV not opening fast enough. At low boost it opens much slower than high boost

Thanks Mate
