I've seen mixed sounds with the ECS DV spacer some get the Stututut sound and some get the Whoosh sound? In a comment someone mentions having the open slots Orientated towards the top and Front of car to get the Stututut sound. If slots are facing Top and back you get the Whoosh sound. But on ECS install it shows indents so there's only one way to install this. Unless I'm not seeing something. Another rumor is only Manual cars get the Stututut, while DSG can only Whoosh. Have you tested different orientation of the ECS DV spacer? Is there a loss in boost when installing one of these?
having the same issue man running a dualkompact bov and a turbo muffler delete only get swooshes this guy i talk to said use a dv spacer if this doesn’t work i’m positive a hks bov will do the trick look them up they sound awsome
Yeah I just got my ecs spacer and it only does the whoosh, the guy that had the turbo flutter did have a tune and an intake, could that have something to do with it?
The orientation of the slots should not matter since the Stututu sound is caused by air in the compressor wheel. I've only tried these parts on a DSG. One possibility that I've not reached a conclusion on yet is the manner in which the ECU closes the throttle plate on a Manual vs DSG. If the throttle plate is closed slowly after letting off the accelerator then the air pressurizing the charge pipes would be able to still enter the engine, at the same time it is escaping out the DV, so that could prevent air from going back out through the compressor wheel and making the stututu sound. If the manual ECU shuts the throttle plate more quickly, it may be more likely to have air pass out the compressor. I haven't seen a good comparison for how the ECU closes the throttle plate on a DSG and Manual, so that's just a theory.
Is it a good idea to run a bov? I know these cars dont have mafs in em but i didnt know if there were any downsides? Looking to get one especially since its a good bit louder than just the spacer
There's no downside to the electronically controlled pneumatically actuated valve that I could find. It's a valve that opens and shuts similar to the stock diverter valve.
Baun DP and mid-pipe with AWE exhaust. I'm not familiar with what the blue ring entails. To my knowledge this is the standard vent to atmosphere BOV that Forge offers for the Mk7.
Forge sounds better but is 100% atmospheric, which makes your car run worse unless it’s tuned to account for the unmetered air. Diverter spacer allows some air to return so it honestly is the better choice of you’re keeping a stock tune
The Mk7 uses a speed density system, so there is no "metered air", that is a reference to a measurement made with a mass airflow sensor, which the Mk7 does not have. A DV spacer accomplishes the same thing as a VTA BOV, redirecting the discharge air outside of the intake.
Love the way the Forge BOV sounds. Thanks for the video

what your exhaust setup? and is this with the blue ring forge dv

Was that bov in a wreck or something? Lol
Not that I am aware of.
