Scirocco Central

Heya,

Does any one know if you can get a flutter dump valve for a 2.0 tsi rocco? And if yes where lol

Thanks

Do flutter type dump valves not need to vent to atmosphere? Which if that's the case no, as VAG use recirculating type dump valves.

They don't run too well using ones that vent to atmosphere.

i'm beginning to notice a theme here, i say go for it

They don't work properly with the engine and sound totally chavvy.

But if you want one........

Listen to wigit!

so if i buy a forge dump valve and block it off so that the air can not ascape and will go back though the turbo will this make the blades spin backwards to make the sound? Only reason i ask is that there was a rocco in reading the other day which had one and it sounded mint!

Do you mean the Tsssshhhhhhh type noise ? (like in video below), DONT buy a forge and then block it off !!!!, the noise of a blow off dump valve is so 2000 LOL, and V Chavy IMO of course

Your on about compressor stall if you fit an open induction kit like the itg etc you will hear it,the whole idea of a dump valve is to stop compressor stall

Didn't realise the sound was caused by the turbo blades going backwards

no not like the vid more of a transformer noise if you search 'MR turbo's flutter' on u tube u will hear what im goin for.

Like i said you need an open airfilter to be able to hear compressor stall as it will echo back through the inlet tract

There you go

Thank you

Does the dump valve release while your accelerating? Just fitted one and it releases when turbo kicks in

But why would you deliberately want compressor stall, might as well stick a potato in your exhaust pipe while you're at it, lol

I'e got a full intake oin my roc, give it some throttle and it makes that sound anyway.

If thats non enough I got a forge spacer you can have
