Sweet strategy! It's pretty clever, covering the BoV and vacuum line. All it really does it prevent the air from leaving, which allows the air to rush back past the spinning turbo, causing the aerodynamic STUTUTU affect. It's not actually bad for the turbine, or indicative of a problem unless it makes the noise BEFORE your boost has finished building.
No, but it slows your turbo down rather than continuing spooling/spinning which means it has to restart its spooling process. Essentially just delaying boost.
@@legacy_smosh5162 It doesn't slow the turbo down, High Performance Academy have a video on their channel where they test exactly that, there is no difference in turbo speed between running a valve and not running one.
Runs perfect .. then does 2$ mod without any kind of tune, then cries cuz subarus are junk and needs engine replaced. But hey . It went stututtu for a while
@@traviskc420 It's not a stock WRX, it already has some kind of aftermarket ECU, looks like it isn't running the factory MAF anymore which causes all the issues with running no valve.
I think the sti could handle it better having forged internals and all but I don't think it would be a good idea on a WRX. Safer than anti lag on a stock motor but kinda sketchy seeing as a bov or recirculating valve is meant to keep from boosting at idle and when letting off the gas. Makes the engine want keep running since you're feeding it more air. Good for racing but not so much for daily drivers
@@bennyboyy7 Most BOV's and recirculating valve are closed at idle, there is no extra air going into the engine without them and the throttle plate is closed either way, the only issue is if the ECU has metered the air and adjusts fuel causing a rich condition, this is a problem with the factory ECU and air flow meter, it can be tuned out or if you change to a MAP sensor then that won't happen.
@@lulburba5956 it doesnt damage the turbo if the throttle is closed and the surge happens. The turbo is not under any load and it is spinning fully freely at around 80-200 thousand RPM. The air going back is getting chopped up which is why it sounds like that, but it doesnt damage it in any way. It just slows it down
This is essentially what i did to my 2nd gen kia forte koup. I had a professional welder weld on a thick piece of metal to completely block off the BOV and i choked off the vacuum line with a nearby bracket. I bought a new stock BOV though obviously after that to keep handy. I still love the sound of a loud BOV completely venting to atmosphere so I constantly alternate between the flutter noise and loud swoosh noise since its just a quick 5 minute reinstall 😊
i dont have BOV on mine theres stupid ECW ......no bypassing that i suppose .....tried unplugging diverter sensor so it wont pickup how much boost sits in pipes so it would just go back in turbo and make sututu but no .....waste gate is separate cabelage ...

what doesd it mean when its before boost buildup?
@@user-so7gg9zz3rbasically if your peek boost is 20lbs and the sound comes before that when you left off then that's bad
@@user-so7gg9zz3rthat the turbo is likely broken
Do you lose any hp if you do this?

First everyone were obsessed with BOV now their ditching it to hear abit stutututuuuuu lol
Just did this. Had a GFB BPV, I prefer the zututu sound better than the atmospheric sound it was giving.
Stututut....boom! Turbo gone!!!!
So if I got a top mount? Jst block out the bov? The triangle part? Kilts jst completely block it off like I had no bov?

There is no next video ...lol he must've blew engine and got something else.

Nice sound, hey what turbo do you have on the car and what coil overs thanks.
Your engine bay clean as fuckkkkkk what mods you got??? I have a turbo xs hybrid bov and sounds like this but holy moly I need a bay like that
WX STI? 😂😂
Is that bad for the car? Removing the bov?

Compressor surge.. I thought this isn't healthy for turbo
it isnt lmfao this is horrible for your turbo
@@lulburba5956 nah.
@@DriftNick yes it is… it creates back pressure on ur turbo… moron

@@lulburba5956 Creates back pressure?
What turbo !???
My question is, are there any bad’s from this.
Not really unless you got like 35psi of boost
thank you for the comment and answer!
i wouldn’t listen to him if your turbo makes the fluttering noise before your turbo is done spooling you probably shouldn’t be doing that
if you get the right setup an intake setup can be a simple answer to the stututu
this guys car sounds like shit afterwards lol
Does that car have 2 step or something? How’d it make that sound
launch control
i guess
Your turbo blow up yet?
It wouldnt effect anything unless u had compressor surge while the throttle plate was open. All it does is increase wear and tear by a little.
Is that stock turbo?
whats your turbo bro???
nice and clean sound!!!!!!!
how does your launch control sound like that ????

That's awesome bro, I'll get getting mine soon
Allllssssoooooo how do u build boost by standing still at a parking lot?????
Launch control
Yess that's the sound we love!!
Remember this is a temporary set up this should not be left on for long periods of time
@@subiesoup8182 lol I had no bov for months 30,000+ ks and it was fine 😂
Why does it sound like it has a fmic
@@BennyRiot FMIC are bigger so naturally the sound echoes more.
It does have a front mount
Is that a automatic?
No Lol

What is causing that pulsating sound at 6:45 and 6:50 when getting into the higher revs just before letting off?
That’s an EWG
An external waste gate.
