Someone needs to make a video on how to make create flutter or, a "dose pipe" I'm visual so just saying "You need a pipe in front of your turbo" Doesn't help lol
@VaginaFeast@pissuoff1 yes you can block the bpv or bov. what is causing that noise is simple. just to clarify, when you block the bpv, the compressed air in the lines have nowhere to go so the air bounces between the turbine and throttle plate. thats why, the longer the tubing, the slower the flutter.
Your goin to thrash out the turbos bearings!! Cause when your closing the throttle all the compressed air is forcing it's way back through the compressor the wrong way causing it to stall repeatedly hence the flutter if u don't believe me google it.
i cannot agree with u your clearly lying. my 2 year project was based on the effects of this on turbochargers and i have an assignment which is over 300 pages long on it. i even went to prodrive to discuss my findings. the only thing i can agree with u is the 'small' loss in RPM in shaft speed but im afraid to say it doesnt come close to stopping. ur fighting a losing battle mate iv done more research and intensive testing than u can imagine.
@adamski100988 really i dnt give a fuck what you or any one eles says it is not good for the turbo end of story you may aswell ues your 300 pages of info as shithouse paper cause its utter shit if it states it does not harm the turbo when youve worked on multimillion dollar merc cranes and 16 cylinder engines you may be able to porn some info off on to me but im not buying you crap
@geta8pac well ur clearly a shit diesel mechanic if u can even grasp this concept!! im a turbo specialist u retard!! u must b a yank ur all dumb as fuck when it comes to cars thats why u cant build them. ur just another one of them people whose simple mind is led astray easilly by the internet. u know nothing i wouldnt let u anywer near my car
@adamski100988 well dude im not trin to piss you off but why do most cars have a factoy bov setup they are not there for looks or sound they are ther for a purpose also a customer brought his 2.5 turbo skyline running a t3t4 with his bov spring wound hard down the turbo is only 9 monts old and it his not happy it has been hitting the housing our manager void the warrenty as the bov had been tamperd with
it is not harmful in anyway,,,its just the choppy sound of the air passing through the compressor blades!! it is impossible for it to spin backwards etc so how can it damage it!! ur all dumb fucks look up true compressor surge
@geta8pac wat u mean do my homework?!? u dont even know who i am!! iv studied 4 years of motorsport engineering and work on turbocharged engines everyday of my life so im plenty clued up. the turbo doesnt come close to stopping believe me. have you ever looked a turbocharger speed graph when chatter accurs,,,im guessing not. i kno people who have ran a car with it for over 7 years at 20 psi without a puff of smoke.
@adamski100988 bud ive seen it with my own eyes the turbo stops maybe not in all cases but it is not good ive been qualified for 5 years now and ive rebuilt a few turbos in my time i have seen several speed graphs which show a massive decline in rpm when the relief valve is not performing properly when the throtle body is closed it creates back preassure and it vents by stalling the turbo and finding its way back out the intake of the turbo witch is not good for it in any way Peace
btw i hope you no thats a bad thing its making that noise, it does this when your dump valve or blow off valve isnt able to cope with realsing the pressure when taking your foot off the accelerator. but it does sound great :)
@rostron1234 yes thats correct this is bad it means ur bov spring is too hard and not venting properly which causes the turbo too stop do abit more home work @adamski100988
like sluggish ran like ass boosted on the gauge but didnt take off, all from my bov not in the right vacuum port(half the suck as it should) i also went thru a afm from the blow back of air that destroyed the sensor. only cost me $700 nzd to turbo a sr20de all new parts except turbo manifold all done my self even drilled 5 inches into the block for oil. without removing the sump 5000Ks later its sweetas. will upload my vid
ok when you say "20 year old turbo" and "no shaft play" well to tell you the truth any 20 year old turbo does have play i am a car mechanic and a 64,000Ks 1984 nissan bluebird U11 sss turbo 1 owner old lady and that is a very tidy car and even that has play in the turbo non thrashed or anything. you must have a reconditioned turbo as all turbos wear from cold start . and my turbo on my nissan bluebird U12 4wd attesa sr20de+t did that till it was doing fucked up things
im sure that aint gud for turbo they dont put b.o.v on kars for no reason compressor wheel onli made to flow air 1 way. y not just go out n spend $100 for a replica hks super sequential
@Snakypaintbrush No, it's hard to get 'under-pressure' (vaccum) on an AFM since they are exposed to atmosphere. The worst vacuum they would experience would be at full throttle, which doesn't affect them. But I won't get into the debate on what it can/will damage. However I would suggest you don't do this.
can you tell me if thts bad cause my brother's mk3 was perfectly fine for like 1 week then it started dosing....... if u no whts wrong please reply......
that sucks, i got a stock well semi stock R33 GTS25T skyline and its still got the single stock turbo on it........which i think is the single ball bearing ceramic one.....at it says in the info that this isnt good for ceramic turbos.......but this sounds so freaking awesome and i wont to do it.....but guess i gota save for better turbo....."sigh"
then all u need to do is block off the bov. when you close the throttle the air tries to escape but cant so it echos through the pod filter. to give it this high pitched noise u need to get rid of your afm which means running aftermarket management. then get a 90 degree bend on your intake piping and a hks mushroom filter. should go off bone
No thats not right. He has a turbo, and no blow off valve. The blow off valve relases the air that gets trapped in the piping when the throttle is cut off (let off the throttle). Since there is not a blow off valve. The trapped air get pushed back through the turbo causing that sound.
Dude, think about it, If air is traveling BACK the other way through the turbo the blades are going to slow down, and forcing something to slow down all the time will in time damage your turbo, but hey it might happen in 7years or it might happen in half a year, Doesn't matter And yeah he could of been dosing the same turbo for 7 years but how many rebuilds has he needed eh? But like Deprived777 said this debate has been on going for as long as turbo's have been around and probably won't stop.
@kubahobo Almost anyone will tell you that its bad for the turbo, because once you close the throttle, the pressure will back out through the turbo (which is what makes that sound) and cause the blades to spin backward. However, In my personal experience, it causes no harm whatsoever. I am also fairly certain from my own experiments that the turbo does not suddenly spin backwards or even stall. I have never seen any actual evidence that this causes damage, but everyone will tell you it does.
@ZandrintX In theory, it all makes sense. I used to believe that this was very bad for a turbo, but then I thought about it and decided to do some experiments. In my own experience, there is no damage caused by this whatsoever. I have never seen any evidence that proved that its dangerous. I guess it's just a matter of opinion. Who knows, maybe my turbo will eventually blow up from 20 psi without bov, but until that day comes, I have no reason to believe otherwise.
Compressor Surge is bad, And can be created by having a to small wastegate so the air travels back through the turbo making the blade spin the otherway which will cause damage to it over time. And as far as i know there is no BoV that makes that noise
dude it dose not make it spine the other way think about it.. the turbo is spooled up and spinning at a very fast rate how with it just spin the other way from a lil bit of air...i know this 100% will not fuck anything at all...the sound is just air gettin chooped up by the turbo blades and havin stainless pipe on the front of the turbo amp's the sound..VL2DY4 has been dossing the same turbo for 7 years with no worrys at all...its not the dossing that fuck's the car its the cunt or cant drive
lol it sounds retarded!! people seem to think that it will damage the fins on the turbo, some people believe its ok..that debate will never be over. but why tempt fate? a bov was invented for a reason...and that compressor surge sounds retarted!!
get a bov and keep the spring tight then atleast u will get some compressor surge at low boost but when u let off at high boost it will vent out.
yeah mate you do its the air left in the cooler pipe's that get's chooped thro the turbo that make that sound oh and a stainless bit a pipe on the front of the turbo
not literally but the compressed air has no where to go (closed throttle and no BOV/by pass valve) thus it tries to escape through the compressor side all while the exhaust side is still spinning it up. It can cause bearing damage.
Do you have to do that for turbo. II am freakin cheap.I get paid yearly and dont have enough for a turbo, what can i do to make my car have that sound?Couyld i just stick it to the stock system? Funny as my thread is, Its just a simple question.
Dude I love it.. Do you have a bit more pipe inside the pod?? I used a 170mm pipe on my mates 33 and it is dynomite.. I will be putting it on here soon..
The only reason racecars don't have them is because the change gear so fast if it lets the air out it has to fill the inside area with air again before the engine gets it!
all standard 90's skylines (R32 and R33 GTSt 2.0 and 2.5 and GTR's twin set up) have ceramic turbines with either a ceramic or nylon compressor wheel, the only exeption is the R34 gtr
which has steel internals,
TBH I ran my stage 2 T3 for a year with it Stalling and it was fine, the only issue is that it's slow to come back on boost after let off compaired to a dump/blow off valve or recirc ;)
Indeed. The slow re-boosting is a downfall. Likewise having dose is also bad for performance. The dose pipe is connected right to the front of the turbo, the turbo is bolted straight up to the hot exhaust manifold. Hence it sucks in hot air, which is a downfall.
it also depends on what the internals of your turbo is made of, for instance a skyline gtst turbo has a ceramic blades bonded to a nylon compressor blade, compressor surge will destroy them in no time at all,
if you have a turbo with steel internals it will last longer, to be honest though the spool time is noticably longer when running this way as apposed to using a blow off or dump valve, even I do like the sound,
Well that could be the difference. r32, gtst with rb20det, has a ceramic turbo with nylon compressor blades, which will die from dose. I have r31 with rb30et. the turbo is stock VL turbo one. which has steel internals which should not die. and in the 1 year of having dose, it had the same minimal shaft-play as when i bolted the turbo on 2 years ago.
Just wondering, does a dosage pipe work in the same way a regular blowoff valve would work? Or is it completely different because of the way waste air is released?
Nope, Dose pipe works completely different. The noise is made by turbo and amplified by pipe. It doesn't vent the boosted air mid cooler piping like a regular BOV.
idiot, if you knew the mechanics of the turbo youd know compression surge is bad...it strain the axle of the turbo, the compressed air that usually goes through the throttle can't go anywhere but back out the turbo blades, this causes the turbo to spin the opposite way contrary to the exhaust side blades..
yeh, but those forces have not been proven to damage turbo's. i have had simple VL-RB30 turbo for a year, no BOV and 12psi and the turbo is still is as tight as the day i put it on.
manufactures wouldn't waste money on putting bov as standard equipment if it wasn't needed, they don't think of whats gonna happen to it for 2 years, they think of it of whats gonna haven after 5 years, or more.
but i wont get into this topic cause what i can i say, im not usin a bov either :P lol (i've got a turbo'd 31 too :D)
afaik the air rushes past the compressor blades and slows it down. it doesnt violently revert the inertia of it. if that were the case then yes it would ruin a turbo. dosing isnt that bad in the short term. its long time turbo longevity and how much boost you run. at the end of the day most people who want that sound use a car like that as a toy and thus dump the car within a year so they dnt give a rats arse.
I love your setup mate. I'm putting an RB25DET into my Z31 300ZX and want to use a dose pipe but don't know where to get them from. I'm in the US btw. Could anyone tell me where I can get a dose pipe from or how to make one? I appreciate all of your help. Thank You.
A Typical F***Wit known as the Muzza. What could be a more perfect example, seriously go down to the scrap yard you may be lucky enough $50.00 for that heap of junk. I would hate to see the shaft play on that turbo after you have finished revving the sh!t out of that engine. And night crawler, your right about one thing, you would draw attention to yourself with a car that sounds as ridiculous as that - as for the hotties i don't believe it counts when its your sisters and cousins.
Hey man. This was an experiment. I have not run a BOV in the turbo system for a year and have added a dose pipe for the last 6 months. I took my turbo off a month ago and its still tight and firm. No shaft play. Its a 20 year old turbo and is still fine. So I am NOT ruining my turbo. So learn from this. Learn that compressor surge doesn't always wear out turbo's.
All i can say is that your very lucky your turbo isn't stuffed. The main thing is every time you change gear your turbo losses spin speed and when you put it into the nexted gear the turbo has to spin up for a lower spin speed then it would if you had a BOV instaed of it blowing back through your turbo
Fuck off you fucking limp dick faggot!! How can u judge his car when u have not seen it! And dose does not destroy turbos u fuck wit, that is the biggest marketing lie just to sell gay ass blow off valves.
If he wants it to sound like that, good on him. Why rag on him you insecure geeky little fag! Get a life cunt.
Compressor surge may slow the turbo down. However whether this means the turbo actually gets damaged is not fully proven. 20 year old VL T3 Turbos handle it.
What if you have the dose pipe, no bov, but leave the AFM just after the POD ? Would there be a noise difference ? Whats the point of relocating the AFM ?
If you do this, your AFM will die sooner, as the turbo will spit back a lil bit of oil which ruins AFM's. The dose will not be as loud or clear. Better throttle response if AFM is relocated.
A dose pipe is a pipe connected to the inlet of a turbo. And by NOT having a BOV, u get compressor surge. Which is amplified by pipe to make DOSE noise
Why would anyone want to make their car make this noise? so gay

@renegadeR31 a metal pipe with a filter on it attached to the turbo inlet...so its just the air intake...?
hollow121314 1 year ago
yep dose pipe is just a bit of pipe of the front of the turbo it can be as short as ya wont or as long as you want..
and a AFM = AIR FLOW METER

compressor surge, not very healthy.

the flutter is the blades in turbo cutting the air, what i've been told, turbo wont last as long tho
kooori12 2 years ago
Ya its just the compressed air trying the slow down the turbo and spin it the other way and yes the turbo wont last long. Throw a BOV on there.
andy9775 2 years ago
hmm here it is again the hole turbo spins the other way crap.. i dont know who told ya that but its not true..
bignick3174 2 years ago
not literally but the compressed air has no where to go (closed throttle and no BOV/by pass valve) thus it tries to escape through the compressor side all while the exhaust side is still spinning it up. It can cause bearing damage.

Do you have to do that for turbo. II am freakin cheap.I get paid yearly and dont have enough for a turbo, what can i do to make my car have that sound?Couyld i just stick it to the stock system? Funny as my thread is, Its just a simple question.

could you upload a video of how to make and install a dose pipe?
atsall 3 years ago
so the dose pipe comes off the turbo instead of putting a pod?
or you can put a shorter pipe the the pod over it? am i correct? i want to know how i have a vl intalling a turbo on it atm

People run straight pipes from their turbo's. I put a lil pod over it. I didn't want to feed my turbo or engine sand and dirt.

some ATMO cars with pods make that noise when you turn the car off, but only very faintly.

The F1 1500hp turbo cars didn't run bov, HR31 skylines didn't run bovs, Porsche GT whatever turbos didn't run bovs.
They are there for emissions and to stop the 'flutter' noise as customers think that something is wrong.
roflex2 3 years ago
The only reason racecars don't have them is because the change gear so fast if it lets the air out it has to fill the inside area with air again before the engine gets it!

what the heck is a dose pipe?
Blahman240 3 years ago
all standard 90's skylines (R32 and R33 GTSt 2.0 and 2.5 and GTR's twin set up) have ceramic turbines with either a ceramic or nylon compressor wheel, the only exeption is the R34 gtr
which has steel internals,
TBH I ran my stage 2 T3 for a year with it Stalling and it was fine, the only issue is that it's slow to come back on boost after let off compaired to a dump/blow off valve or recirc ;)
cheers

mattbsierra 3 years ago
Indeed. The slow re-boosting is a downfall. Likewise having dose is also bad for performance. The dose pipe is connected right to the front of the turbo, the turbo is bolted straight up to the hot exhaust manifold. Hence it sucks in hot air, which is a downfall.
renegadeR31 3 years ago
This comment has received too many negative votes show
in other words, your a cock sucker no1 cares it sounds mad. eat my cock plz
chevapi2 3 years ago
it also depends on what the internals of your turbo is made of, for instance a skyline gtst turbo has a ceramic blades bonded to a nylon compressor blade, compressor surge will destroy them in no time at all,
if you have a turbo with steel internals it will last longer, to be honest though the spool time is noticably longer when running this way as apposed to using a blow off or dump valve, even I do like the sound,
mattbsierra 3 years ago
Well that could be the difference. r32, gtst with rb20det, has a ceramic turbo with nylon compressor blades, which will die from dose. I have r31 with rb30et. the turbo is stock VL turbo one. which has steel internals which should not die. and in the 1 year of having dose, it had the same minimal shaft-play as when i bolted the turbo on 2 years ago.
renegadeR31 3 years ago
Just wondering, does a dosage pipe work in the same way a regular blowoff valve would work? Or is it completely different because of the way waste air is released?
Ttran778 3 years ago
Nope, Dose pipe works completely different. The noise is made by turbo and amplified by pipe. It doesn't vent the boosted air mid cooler piping like a regular BOV.
renegadeR31 3 years ago
btw what is dose/dosing? ive only heard of this recently..plumbed back bov or no bov??

Compressor surge does ruin your turbo you idiots.
justwateva502 3 years ago
prove it?
uNeeKi 3 years ago
idiot, if you knew the mechanics of the turbo youd know compression surge is bad...it strain the axle of the turbo, the compressed air that usually goes through the throttle can't go anywhere but back out the turbo blades, this causes the turbo to spin the opposite way contrary to the exhaust side blades..
sqnshl 3 years ago
yeh, but those forces have not been proven to damage turbo's. i have had simple VL-RB30 turbo for a year, no BOV and 12psi and the turbo is still is as tight as the day i put it on.
renegadeR31 3 years ago
manufactures wouldn't waste money on putting bov as standard equipment if it wasn't needed, they don't think of whats gonna happen to it for 2 years, they think of it of whats gonna haven after 5 years, or more.
but i wont get into this topic cause what i can i say, im not usin a bov either :P lol (i've got a turbo'd 31 too :D)

...meh who cares it sounds good.. just like mine hehe
Audi2000t 3 years ago
afaik the air rushes past the compressor blades and slows it down. it doesnt violently revert the inertia of it. if that were the case then yes it would ruin a turbo. dosing isnt that bad in the short term. its long time turbo longevity and how much boost you run. at the end of the day most people who want that sound use a car like that as a toy and thus dump the car within a year so they dnt give a rats arse.

A Typical F***Wit known as the Muzza. What could be a more perfect example, seriously go down to the scrap yard you may be lucky enough $50.00 for that heap of junk. I would hate to see the shaft play on that turbo after you have finished revving the sh!t out of that engine. And night crawler, your right about one thing, you would draw attention to yourself with a car that sounds as ridiculous as that - as for the hotties i don't believe it counts when its your sisters and cousins.
pellegrinipatrick 4 years ago
Hey man. This was an experiment. I have not run a BOV in the turbo system for a year and have added a dose pipe for the last 6 months. I took my turbo off a month ago and its still tight and firm. No shaft play. Its a 20 year old turbo and is still fine. So I am NOT ruining my turbo. So learn from this. Learn that compressor surge doesn't always wear out turbo's.
renegadeR31 4 years ago
All i can say is that your very lucky your turbo isn't stuffed. The main thing is every time you change gear your turbo losses spin speed and when you put it into the nexted gear the turbo has to spin up for a lower spin speed then it would if you had a BOV instaed of it blowing back through your turbo

corect me if im wrong but compressor surge is bad for the turbo, engine,etc. the surge will force a rotational stall which is bad.
kboomer1 4 years ago
Compressor surge may slow the turbo down. However whether this means the turbo actually gets damaged is not fully proven. 20 year old VL T3 Turbos handle it.
renegadeR31 4 years ago
if u put a dose pipe with a mini pod u'll get a way better dose :)
VL2DY4 4 years ago
Probably, but I want the intake to be 100% sealed from dust and have minimize the chance of starving the engine of air under hard boost.
renegadeR31 4 years ago
What if you have the dose pipe, no bov, but leave the AFM just after the POD ? Would there be a noise difference ? Whats the point of relocating the AFM ?
KISIN95 4 years ago
If you do this, your AFM will die sooner, as the turbo will spit back a lil bit of oil which ruins AFM's. The dose will not be as loud or clear. Better throttle response if AFM is relocated.
renegadeR31 4 years ago
happened to me.
walker2006au 4 years ago
A dose pipe is a pipe connected to the inlet of a turbo. And by NOT having a BOV, u get compressor surge. Which is amplified by pipe to make DOSE noise
