Dump / Blow off Valve .. PSSSHT!

[mint]

:wave: howdy guys!

Im interested to hear what a standard S15 sounds like, my mate kyle had a turbo'd golf and he got a new dump valve for it which made it sound well differant.

My other buddy Jay has a S/Charged is200 and his thing sounds fiarly crazy lol.

Anyone got sound clips? Or whats the best Dump valve that you guys rock? OEM or Aftermarket? i dont know anything much to do with FI to be honest like.

Gotta learn somewhere tho.
Mint

The standard BOV doesn't make any noise. Aftermarket BOVs to atmosphere are just plain :ghey: , plus they'll make the drive as jerky as fook. Do it the proper way and get a proper BOV that recirculates (like a HKS SSQV and adapter) and replace the existing BOV with it :nod: The pigeon noise sounds much more than the :ghey: Pssht... :nod:

Here's what full-on pigeon sounds like

Pigeon

Wouldn't be as loud, but you get the idea

Right click it and save as, then play it

Mine as the pigeon sound already is there something after market thats making that sound. I have a BOV to fit just an atmospere one, will that take away the pigeon sound cos like that better!

that pigeon sound is what i thought it wud be like, amazing.

So what company makes that sort of BOV and i mean IS it just a simple case of replacing the OEM one? Thanks for this and excuse my noobish behavour

Reason being im away to look at a few 15's in a couple weeks fingers crossed.. but shhh

No, you'll get pigeon if you run without a BOV or recirc valve. Its back pressure playing on the impeller blades. You will still get it to a degree if you recirc (especially with A'PEXi filters). The difference is that its safer on the turbo if you run higher boost. You can also experience a slight lag running with just pigeon. If you take a look in my Tech Guides (link in my signature), it shows how the pigeon mod is done.

Thanks very much for that chief good readin there.

Shame im pretty useless when it comes down to the mechanics, so like i said the whole FI is gonna take a min or two to click with me but yeh i got my insurance quotes today and lets say... its doable.... alot..able i had a serious smile on my face like!

The clip of Noob drifting is Pigeon with very high boost, the pitch alters depending on the boost pressure, i noticed it went alot higher going from 0.8bar to 1.2bar.

I have a pigeon (removed bov and blocked off neccesary piping), and it sounds awesome and changes tone as I let off at different rpms.

However, I've just bought a BOV and am going to fit it.. will I need to modify any of my existing set up to do this right?

 

[raytsang]

So which setup is best for higher turbo boost??? Atmos or recirc?? and is safer for the turbo?

 

[mint]

iv been told leaving the OEM setup it best for the turbo as the Atmos and recirc will just put stress on the turbo.. this right enough?

 

[ichi-go]

oem IS recirculate
