Yeah to an extent it is bad, that's why you run a bov or recirculating valve on turbo cars, it manages compressor surge. A properly setup external waste gate sounds like this too, even with a bov. You'll hear stu tu tu first from the waste gate followed by a whoosh from the bov. Long story short compressor surge to an extent is natural for any turbo, but to extreme is very bad and will damage the turbo. The Turbo smart video on compressor surge helped me understand.
@@roninlaw9824 Thanks for the heads up, that's interesting... my S3 was fitted with a Forge Recirculating valve before i bought the car a few weeks ago, i was worried about the stu tu tu sound, but you reckon that is normal... so maybe the sound is from the wastegate? plenty of power and goes like a rocket.. i'll check out the Turbosmart video... thankyou
No it isn't bad. There's a myth that's been argued for like 30 years about turbo bearings wearing faster, but it's never been proven to be a real thing. Compressor surge when you lift your foot is fine. If you get compressor surge while on throttle, THAT is bad, because it means your car isn't making use of all the boost. Either a mismatched turbo, or too much boost. Which can definitely damage your engine, and possibly turbo, as its still being spooled up while not having anywhere to send the air. but thats an entirely separate issue and has nothing to do with a bov. I assume that people hear about the second one and apply the same logic to the first. "I've heard compressor surge is bad for the turbo" Open throttle surge, yes. Closed throttle, no. Unless your turbo is made of glass or coke cans, it'll be fine.

As an Aussie I'm sure you've heard of Turbosmart. Check out their video on compressor surge. That's why your hearing that violent flutter. It does sound cool, but I wouldn't recommend it.
about a month ago i bought a blocking plate for my mums mazda 6 mps and i installed it but no flutter, so im guessing that the stock intake either muffled the sound that much or a vacuum line wasn't blocked.
Benchmark Solutions Speed density kit with 3.5" Intake to suit Stock frame setup if you want flutter its the best thing you could ask for, Also makes driving an Evo 3x better with MAF in the fucking bin!
does capping off the diverter/blowoff make the car run rich? I know if i add a blowoff on my mk1 TT the engine runs rich due to the lack of the recirculating air the ecu has already accounted for
Hey Zac, looking at gt86 turbo kits and whats the main contributor to the flutter sound. Many of them dont run BoVs but sound very different. the HKS one sounds epic, do you think thats due to the turbo housing (would you know if most modern turbos from garret and precission have anti-surge to prevent them sounding like 90s JDM cars?), intercooler pipe routing lenght? (many kits go around the bumper;long route vs some going through the crash bar; short route), or having a slight dose pipe? (some having filter connecting to turbo vs some having a 2-3" dose pipe for Map sensor).
Just a little help the biggest contributors would be the amount of boost your running as well as the length of the piping between the turbo and throttle body as far as the anti surging tech I would do research on those turbo kits I would say most modern ones tho would have anti surging hope this helps
Airbox is fine, you just need metal intake and charge pipes. And a bit more of straight length directly in front of the compressor. No sharp bends or sudden cutoffs or change of direction (back-to-back bends) either. Also, if you have an anti-surge housing, get a straight housing, instead, or block off the anti-surge somehow. You could just use an undersized pipe to bypass the anti-surge if you don't wanna mod or buy another housing. The absolute best dose will come from a non-anti-surge housing with a correctly sized diameter metal intake pipe that's straight and at least 3x as long as the diameter, with all metal charge piping. Anecdotally, different compressor wheel designs might also dose differently. If it's in the budget , try a 9-blade wheel, 5+5 blade wheel, and a 7+7, depending on what you already have and what's available for your turbo. Hell, a nice billet compressor wheel will be a solid upgrade in general, anyway.
Great video Zac. Yeah I'm keeping my AU ll Ford Falcon SR sedan - Narooma Blue - it's an Automatic but could be converting it to T5 5-speed manual and it'll be Ford Gearknobs factory Grandpa spec looks for my strict liking - That's ok we all like different things.

Look how happy a flutter sound can make a man
Just tried this on my n/a falcon, didn’t work 😞
Keep trying bro
@@ZacBaldy 😂😂
Get one of those turbo whistle things for your exhaust, that might help!
@@TaffPlaysgood concept! But when i got mine it did nothing
Try again it worked for me
I have an adjustable gfb bov and just tightened it full tight so doesn't open lol
Sounds good! Mine definitely got louder after i put an ARC box in.

does it reduce power? i find with my car taking the vacuum line off and blocking it shut theres a significant difference in power. its more sluggish
Certainly shouldn't. unless you've opened up another vac leak somewhere?
You probably haven't blocked it properly, which will cause a vacuum leak.
But isn't compressor surge and the stu tu tu tu sound bad for the turbo?

Can somebody tell me what COP he uses please?
Steel inlet pipe makes it sound wayyyy better
aluminum gives the best sound

Hahaha up the 33 :P I dont see why you cant on the Pathfinder ;)
Let me know how you go if your doing it to your pathy as i would also like to know if it does work haha
Pod filter done and dusted
Isn't compressor surge bad for the turbo?
of course it is, in long term use
What turbo is it?
are these mods unhealthy to your car instead of a blow off valve?
Some cars don't like it as the bov outlet is also used as a reference for IACV, but 99% of cars love it :D
Does this work on 2011 Subaru wrx?
Will this work on a civic type r fk8?
can this be done on a 335i n55 engine? it has a bov
As an Aussie I'm sure you've heard of Turbosmart. Check out their video on compressor surge. That's why your hearing that violent flutter. It does sound cool, but I wouldn't recommend it.
Abarth punto ????
Another option is to fit the bov in reverse.
Have done the same on my 6 😅
So do you get the flutter?
Sure do
Hahaha that is too easy :P
@@mrminiature11you will get flutter from that
I have used a smaller one of these as an insulator on the charge stud for the alternator in my RE Capella lol!
beautiful car brother
Idk about you guys but I back into parks almost everywhere but the only place I don't is in the garage
We out here... Deleting 1 BOV at a time!
Every like this video gets is 1 BOV deleted from this world!

No it doesn't :)

Hi zac Is this good for the engine?
its fine
Sound great 🤘🏻
would you need a tune after this ?
Nop
Wouldn't it just be easier to make sure the BOV stays permanently closed.
Much better! That BOV sounded like what a typical jdm lover 12 year old would want 😂😂😂
Haha its a cool sound but flutter is far superior
Nahh thats the HKS SQV HAHAHA
lol watching this rn bc i crashed my brz so im looking up turbo flutter videos for my new Q50😂
does capping off the diverter/blowoff make the car run rich? I know if i add a blowoff on my mk1 TT the engine runs rich due to the lack of the recirculating air the ecu has already accounted for
Aren’t you building a turbo VS commodore on keep it reet ?
Haha that's Tali :P
@@ZacBaldy ok , are yous brothers then ?
Can my 2l diesel also make this sound?
Doesn’t the gfb bov not allow you to just close it and not vent to atmosphere?
Tried that... doesnt like it :(
did you sold your Rx7?
🚨🚨🚨 ATTENTION Ya boy needs some new silocone couplers /hoses they are starting to look crustier than my only pair of briefs that i washed last month

I have a new set of Stainless 45's ill be welding up to make a nice dose pipe and deleting the MAF :D
Will be back when your turbo goes byebye
Old school turbos and eBay turbos go bye bye newer turbos and pretty safe unless you hear flutter while on throttle it’s fine
Good thing it doesn't destroy turbos.
@@Rb__boat Pretty much every turbo car pre 1990 didn't run bypass valves, never had any issue with those old turbos and flutter.
@@DriftNick exactly even people with bov tighten them to get dose always had flutter on my cars and love it 🤣
It's not going to go, stop drinking the compressor surge koolaid
The fact it's s word
Seems silly to risk damaging the turbo to just make a funny noise.
Good thing it doesn't damage the turbo.
@@DriftNick That's a subject of much debate.
@@johnmcmullen456 It's not a debate for the people that have actually run no valve.
