lol i love how no one can think out of the box. this valve would help with snapping open the throttle from low rpm where the turbo is hardly turning and out of drive force. depending on how close the turbo is to the throttle body, the engine will receive less air until the turbo starts turning and compensating for the restriction it causes. it makes sense in theory, whether it would be a noticeable difference or not i don't know.
@turtlemann14 makes sense if you were to launch at 1500rpm... but why would u launch at 1500rpm? good bov if you want to drive round in a civilized way.
@turtlemann14 Fair point, but I personally would have to give it a try before I make my mind up about it. I see exactly what they are getting at with the idea, the design I have in my head for an advanced version would work more air efficient but I don't want to share :P could be my next project.
WHAT THE FUCKKKK are you talking about, all bovs stay closed until they need to vent. This is the biggest load of shit video I've ever seen. You give this product absolutely NO credibility. lololol
hahahahah this guys an idiot. motors dont rely on the air the bovs to sucks in, the motor was running like shit bc you took the vacuum source away from the bov. has nothing to do with how slow/fast the bov is closing in this case.
why on earth would even need throttle response coming off of idle in the first place?? the honda makes it's power at like 7500 RPM, so, ideally, in any race setting, you're going to keep the RPMs in the powerband, and so throttle response from a closed throttle position is absolutely worthless.
if you are bypassing the turbo intake, it's going to take even LONGER to reach full boost when you're under load. congratulations, you just increased lag.
Wow, I can't believe an actual company would post a video full of absolute NONSENSE! If this guy is a rep he should be fired, if this guy owns the company, it should go out of business. Let people who what they hell they are doing produce performance parts, I can only imagine what some kid would have to deal with if they called for tech support. Better yet, the guy in the vid needs tech support, and anybody that needs tech support to put a BOV in shouldn't be installing ANYTHING.

Every BOV ever made ever does this when setup properly. The spring inside this and all other BOVs will close the valve long before your turbo has spooled up. This valve shuts just by blipping the throttle. Until you get positive pressure you're still basically running NA sucking through the turbocharger and intercooler.
Only a dedicated one way valve or complicated vacuum system will leave this valve open while you are off boost.
Wow this is actually a very solid design for a blow off valve. I'm considering buying one for my 92 prelude as soon as i finish rebuilding my h22a and swapping it in. Wow this will actually increase torque, not by much but I'll take what i can get :D
jesus.. it's not tuned properly. It's getting a "better recovery time" because it's running rich. When you allow unmetered air to enter the system, it's leaning out the mixture.
@fafinaf no because what happens to all that boost in the intercooler and piping after you let off the throttle and the throttle plate closes? compressor surge is what happens cuz the air has no were to go but back out the turbo the way its trying to come in. that's a dangerous combo for a turbo
Half of these comments are backwards and ignorant. I wouldn't even say that this system is going to provide any kind of noticeable gain. I at least understood the video and operation, which 90% of you cannot grasp. Why do you guys bother watching a video about a BOV when you don't understand how a engine operates?
Okay but what about contaminates? Wouldn't you need to have a filter in front of the opening on this bov as it stays open at throttle sucking in dirt and grime into the intake manifold? Bypassing the turbo means bypassing the air filter too right?
always nice to see people who ACTUALLY understand this shit. props to your company and your innovative products; i hope to buy some of your products in the future!
LOL @ "bypassing the turbo"... how is that done? The turbo is connected to the manifold. As for the theory of sucking the air through the blowoff valve... that's a joke too. The BOV sits after your MAF/MAP sensor so that air being drawn in is not metered. This BOV is a joke.
it doesnt suck in air you fuckin moron it is relieving or blowing air out of the BOV at idle or under vac. It closes as soon as its time to build boost. This also keeps the compressor wheels spinning free. You need to get a turbo car and learn something before you post dipshit. dont knock something till you try it or actually understand the philosophy behind it.
WRONG! Apparently you don't own a turbo car or a BOV. A BOV relieves compressor surge ONLY, it opens on boost when the throttle plate closes (shifting or coming off throttle), it lets that compressed air out into the atmosphere instead of it hitting the closed throttle plate and backing up against the compressor side of the turbo, slowing it down and stressing the oil seals. You don't know what compressor surge is, no problem, just don't act like you know what you are talking about...
Most stock turbo vehicles have a dump valve that vents to the air intake instead of the atmosphere. If that's the case, all you have to do to hear the (Whoosh) sound is get a CAI system instead of the air box. At least thats what I did on my S60 T5.

LOL @ jack black. I didnt really notice it until i read the comments and now im laughing my ass off. The best jack black impersonation is at :27-:30. LOLOL
I have a doud, I´ve a GReddy type rs but it opened to late so I took off one spring, now its fckn great!! but in "ralenti" (dont know how to say it in English sorry) when you dont give gas! it is a lil bit open, is it good? Thanks to the experts!!!
......you're saying this opening sucks air in for better throttle response away from idle? That doesn't make sense as if its drawing this air from where its routed back to the main pipe thats a closed system, the air drawn in may as well be that coming through the main pipe as it does with a recirculation valve. How does improve throttle response away from idle, Either I don't understand what you mean, or there's no difference/benifit to this over a standard recirculation valve.
It sucks in air right after the airflow meter, before the turbo, so it dosent have to breathe through the turbo. When the turbo in not spooled it is a restriction in the intake.
I dont get how this is different to a normal recirculating valve. You're saying that the open end where we can see the piston in the video would normally be routed back to the main pipe after the MAF sensor, yet ........
The difference.. the only difference. Is that the valve is OPEN under no boost and CLOSED under boost.
A normal blow off valve is set to a certain pressure value (tightening/loosening) and is CLOSED until the pressure inside the intake piping is higher than the value set. Usually when you take your foot of the accelerator and the air is no longer getting into the engine and has to escape the piping, it escapes through the blow off valve.
so let me get this straight you put it after the mass airflow and filter but then it sucks up unfiltered air and i know thats bad. so could you put sometype of filter on it but still mount it in the sameposition for a little bit more engine safety so you dont suck in chunks of stuff?
you mount it on your charged piping then re-route it back and dump it into your intake piping AFTER the maf sensor. that way it's not taking in any air that isn't measured already and you're not running lean on idle and rich when changing gears.
compressor surge is generated on a forced induction vehicle when the driver lifts their foot and closes the throttle plates, there is now positive pressure in the intake piping after the turbo. if this pressure is not relieved by a blow off valve it will attempt to push it's way back out the way it came to achieve neutral atmospheric pressure decelerating or worst case scenario possibly reversing the spin of the compressor of the turbo, and backing up the exhaust pressure in the manifold.
"Diversion Valve", it does not "blow off" into the atmosphere. Many cars come with them stock, but people swap them out for "BOVs" because they want the sound. (actually with an open air element you'll still hear the DV plenty IMHO).
The spin of the compressor housing can not be spun backwards, the blades simply cut through the air making the noise. This is indeed bad for your turbo, since the air flow is going backwards it gives the blades of the turbo high amounts of pressure and will wear it out even faster. Thats how Compressor surge is bad for your car.
There's no restriction. You have LESS vacuum with that BOV open therefore MORE initial air available. Hold the throttle just a tad longer and the engine will rev higher. simple.
You actually generate more vaccum in the intake manifold after the throttle plate. This is what all of our customers are telling us. You create a larger pressure difference across the throttle plate with the BOV open.
Dude the valves are all the same the reason it is open is not bc of boost pressure its bc of vacuum the neg pressures in the intake from the motor, when you hit the throttle it closes so what are you trying to accomplish
Hm.I never thought of that,not bad!But I have another idea:The bov is there because without it you will get a pressure buildup that slows down the turbo and gives you lag when you shift,right?So I figured that it might be possible to use a throttle valve in the intake instead!It will be normally fully open,and close fully on signal.The vacuum cleaner gave me the idea:If you shut off the air the motor will actually spin faster because the fan blades dont get resistance in vacuum!Whata u think?

dont leave me comments you fucking bullshitters. everything you fags sell is crap you are marketing lies to these poor uneducated kids. most of them grew up and realized they were being raped thats why the import industry died. aint education a bitch
This has to be the stupidest fuckin thing ive ever heard.. YEA let me suck unfilterd air in my engine yea buddy great idea.. U FUCKIN IDIOT GET AIDS AND DIE!
wow what a deal you can suck unfiltered nasty shit into your motor... yaaayyy. that little bov cant pass enough air to allow an engine to gain efficiency while cruising. and just because a turbo isnt "on boost" doesnt mean its not moving air. its still spinning. god this guy is so full of shit.
Have you ever even used a load-based dyno? At 15% throttle and cruising on the freeway, a 500HP twin turbo Corvette will only make 35HP. Calculate how much air that really means for that displacement and you'll quickly realize that you don't need that big of an orifice to pass that volume. Don't be ignorant. A video is no fun to watch with the BOV recirculated. And if your turbo is efficient enough, you're blowing air out anyhow, even at idle so you aren't sucking in air.
goddamn your dumb. ALL dyno's are "load" based. some are static load like a dynojet 248h some use eddie current like a superflow others are water brake or viscous like a dyna pack. anyway you slice it synaptic is a bullshitter, you are sucking unfiltered air into your motor and all his videos are fucking rigged. i run a dynojet dyno so you can go fuck yourself.
You will NOT get better mileage under cruise conditions. You will have the same delta-P from atmosphere to manifold for a given load, so same net pumping loss. The difference will be how much of the pressure drop is contributed by the throttle and how much comes from the turbo/bov. The only condition that would improve would be WOT, before boost comes on; but that condition has nothing to do with gas mileage.
So for those cars running an airflow meter on the intake side of a turbo..ie a stock SR20DET setup..what are the affects of the engine taking in unmetered air? wouldn't it be running a bit leaner as the ECU is only expecting air thats passed through the AFM, not what is also coming through the bov?
I was just thinking about that anti-stall valve you were talking about. Thanks, quick reply. Looks good..What are these worth in the US? ive seen them for $360 AUD..
lol, the turbo at idle is still putting pressurized air into the intake pipe creating pressure. to vent that pressure you use a bov. no air is being sucked in through the bov, maybe for a thousands of a sec it will when you put gas in it and the time for the bov to close is where it will suck in air.
ok so its just works backwards .. i see what you guys are getting at .. but meh i wouldn't pay more than 14$ for a a bov .. your better off having a regular bov and a check valve to just by pass the turbo to get rid of the " restriction" or do like me and just puta huge turbo on an engien that aready is realy responsive with an auto tranny. have launch on just the motor and once speed comes up the boost will come.
Look up the patent 6,863,260. The change in geometry allows for the ability to equalize the force on either side of the piston, so that no matter how much boost you run, it is still the same amount of force to open the BOV. The valving mechanism is still a poppet valve and not a piston. The actuator is a piston.
And why would i buy anyting from you, if it worked, when i can just take a standard bypassvalve and remove the spring, then the valve will be open as long u got vaccum.
Thats all youre grap is, a recirculating bypass whit a really weak spring.
Synchronic does not have a diaphragm and has a tiered piston actuator that does not leak boost, and is pressure tested to 100 psi not to leak boost. The valve geometry is a pull-type design that seats harder as you run more boost. Try running a weak spring on a diaphragm BOV and see just how fast it closes with boost pressure at the valve face.
All the BOVs and Bypasses i use hav o-ringed light alloy pistons, or, just valve stems like a wastegate whit Oring seat, those will never leak. 100psi, thats like 6.5bars? We test whit factory-standard 10 bars here in sweden.
Hey genius, do you even have a dyno? Under cruising, part throttle loads with vacuum, a twin turbo Z06 only makes 35 HP, how much airflow do you think that requires? Do you know the difference between flow and pressure?
I have acces to a couple enginedynos, rotortest, etc.
35HP uses less than that 20mm, of flow, and thats what i mean, the turbo system haf way less restriction than a small hose.
If it was a 1.5" tube, whit a trottle bypass maybe, i would belive some of it, and that it would make a different on a car whit a Realllly small turbo and IC.
Offcourse when youre taking air from the atmosfere and bypassning the filer u get som results, but when a hose is there, you'll get nothning.
Come on by, any car with the bypass valve between the throttle and intercooler installed, we'll throw it on the dyno and have you see it for youself. Why do you think that the roots blowers have these built in bypasses, even though they don't have the same level of restriction?

@ 454sskilla
Turbo restriction =/= turbo lag.
Turbo restriction is the presence of the turbo in the intake and exhaust paths that inhibits the air's ability to flow freely.
Turbo lag is simply the time it takes for the turbo to spool up.

I have a doud, I´ve a GReddy type rs but it opened to late so I took off one spring, now its fckn great!! but in "ralenti" (dont know how to say it in English sorry) when you dont give gas! it is a lil bit open, is it good? Thanks to the experts!!!

yeah the GReddy type rs is the greatest Blow off valve.

......you're saying this opening sucks air in for better throttle response away from idle? That doesn't make sense as if its drawing this air from where its routed back to the main pipe thats a closed system, the air drawn in may as well be that coming through the main pipe as it does with a recirculation valve. How does improve throttle response away from idle, Either I don't understand what you mean, or there's no difference/benifit to this over a standard recirculation valve.
beavy69 2 years ago
It sucks in air right after the airflow meter, before the turbo, so it dosent have to breathe through the turbo. When the turbo in not spooled it is a restriction in the intake.
turbomkiisupra 2 years ago
I dont get how this is different to a normal recirculating valve. You're saying that the open end where we can see the piston in the video would normally be routed back to the main pipe after the MAF sensor, yet ........
beavy69 2 years ago
The difference.. the only difference. Is that the valve is OPEN under no boost and CLOSED under boost.
A normal blow off valve is set to a certain pressure value (tightening/loosening) and is CLOSED until the pressure inside the intake piping is higher than the value set. Usually when you take your foot of the accelerator and the air is no longer getting into the engine and has to escape the piping, it escapes through the blow off valve.
I can explain more if needed. It's simple.

no, it actually helps the turbo.

driftster99: You might need a retune depending on the setup.
Aliyns 2 years ago
so let me get this straight you put it after the mass airflow and filter but then it sucks up unfiltered air and i know thats bad. so could you put sometype of filter on it but still mount it in the sameposition for a little bit more engine safety so you dont suck in chunks of stuff?
gooferman609 2 years ago
you mount it on your charged piping then re-route it back and dump it into your intake piping AFTER the maf sensor. that way it's not taking in any air that isn't measured already and you're not running lean on idle and rich when changing gears.

how is compressor surge bad for your car?
kon215 3 years ago
compressor surge is generated on a forced induction vehicle when the driver lifts their foot and closes the throttle plates, there is now positive pressure in the intake piping after the turbo. if this pressure is not relieved by a blow off valve it will attempt to push it's way back out the way it came to achieve neutral atmospheric pressure decelerating or worst case scenario possibly reversing the spin of the compressor of the turbo, and backing up the exhaust pressure in the manifold.
TooSlow2Care 3 years ago
But you should add that a DV is better than a BOV because it injets the air back to the intake, the turbo keeps spinning and reduces lag.
VWRacingXZ 2 years ago
what is a DV?
gooferman609 2 years ago
"Diversion Valve", it does not "blow off" into the atmosphere. Many cars come with them stock, but people swap them out for "BOVs" because they want the sound. (actually with an open air element you'll still hear the DV plenty IMHO).
Khronokai 2 years ago
The spin of the compressor housing can not be spun backwards, the blades simply cut through the air making the noise. This is indeed bad for your turbo, since the air flow is going backwards it gives the blades of the turbo high amounts of pressure and will wear it out even faster. Thats how Compressor surge is bad for your car.
eiffeduden 2 years ago
There's no restriction. You have LESS vacuum with that BOV open therefore MORE initial air available. Hold the throttle just a tad longer and the engine will rev higher. simple.
funitsu 3 years ago
You actually generate more vaccum in the intake manifold after the throttle plate. This is what all of our customers are telling us. You create a larger pressure difference across the throttle plate with the BOV open.
synaptic1 3 years ago
what I was saying was..with the Synchronic initially open you have less more initial air before the throttle body.

Dude the valves are all the same the reason it is open is not bc of boost pressure its bc of vacuum the neg pressures in the intake from the motor, when you hit the throttle it closes so what are you trying to accomplish

UnikImpulse 3 years ago
Hm.I never thought of that,not bad!But I have another idea:The bov is there because without it you will get a pressure buildup that slows down the turbo and gives you lag when you shift,right?So I figured that it might be possible to use a throttle valve in the intake instead!It will be normally fully open,and close fully on signal.The vacuum cleaner gave me the idea:If you shut off the air the motor will actually spin faster because the fan blades dont get resistance in vacuum!Whata u think?

95% of the people that have bought Synchronic BOV already had a BOV installed. Guess which one actually worked and they kept? The fact that you are bitter and make broad sweeping statements, like "everything they sell is crap" is indicative that you are biased because you either sell something else, or you are trying to develop product that simply can't produce results. You have also, never used the product, otherwise you wouldn't be talking smack.

Duckyistrippin 3 years ago
You can run a separate air filter on the bypass or route it to the intake after the MAF sensor or air filter. "sucking sand and dirt in a 40k motors isnt really an option for our customers" I'm sure the fine patrons eating at McDonald's don't really care.

mitsuboost30 3 years ago
wow what a deal you can suck unfiltered nasty shit into your motor... yaaayyy. that little bov cant pass enough air to allow an engine to gain efficiency while cruising. and just because a turbo isnt "on boost" doesnt mean its not moving air. its still spinning. god this guy is so full of shit.
Duckyistrippin 3 years ago
Have you ever even used a load-based dyno? At 15% throttle and cruising on the freeway, a 500HP twin turbo Corvette will only make 35HP. Calculate how much air that really means for that displacement and you'll quickly realize that you don't need that big of an orifice to pass that volume. Don't be ignorant. A video is no fun to watch with the BOV recirculated. And if your turbo is efficient enough, you're blowing air out anyhow, even at idle so you aren't sucking in air.
TransmissionProsSD 3 years ago
goddamn your dumb. ALL dyno's are "load" based. some are static load like a dynojet 248h some use eddie current like a superflow others are water brake or viscous like a dyna pack. anyway you slice it synaptic is a bullshitter, you are sucking unfiltered air into your motor and all his videos are fucking rigged. i run a dynojet dyno so you can go fuck yourself.
Duckyistrippin 3 years ago
I guess that's why we advocate recirculating the discharge of the BOV with almost every installation.
synaptic1 3 years ago
If you setup your MAF as a blow though setup with your BOV before the MAF do you still need to run the anti stall on your BOV?
TechSalvager 3 years ago
Nope, no need for anti-stall if you are doing blow through.
synaptic1 3 years ago
You will NOT get better mileage under cruise conditions. You will have the same delta-P from atmosphere to manifold for a given load, so same net pumping loss. The difference will be how much of the pressure drop is contributed by the throttle and how much comes from the turbo/bov. The only condition that would improve would be WOT, before boost comes on; but that condition has nothing to do with gas mileage.
adynes 3 years ago
So for those cars running an airflow meter on the intake side of a turbo..ie a stock SR20DET setup..what are the affects of the engine taking in unmetered air? wouldn't it be running a bit leaner as the ECU is only expecting air thats passed through the AFM, not what is also coming through the bov?
aaronactive 3 years ago
You are correct Aaron, which is why we instruct AFM cars to re-circulate the discharge for maximum performance.

aaronactive 3 years ago
genius where can i get one
sWoLaNdO 3 years ago
lol, the turbo at idle is still putting pressurized air into the intake pipe creating pressure. to vent that pressure you use a bov. no air is being sucked in through the bov, maybe for a thousands of a sec it will when you put gas in it and the time for the bov to close is where it will suck in air.
h2o12 3 years ago
ok so its just works backwards .. i see what you guys are getting at .. but meh i wouldn't pay more than 14$ for a a bov .. your better off having a regular bov and a check valve to just by pass the turbo to get rid of the " restriction" or do like me and just puta huge turbo on an engien that aready is realy responsive with an auto tranny. have launch on just the motor and once speed comes up the boost will come.

imo, you shouldnt use a blow off valve, either internal wastegate or an anti-lag setup

Internal wastegates don't hold very much pressure and force, so they don't work well with anti-lag. You need an external wastegate for that.

All it is, is a piston, recycle bypassvalve... Where is the innovation????
Webrexxx 3 years ago
Look up the patent 6,863,260. The change in geometry allows for the ability to equalize the force on either side of the piston, so that no matter how much boost you run, it is still the same amount of force to open the BOV. The valving mechanism is still a poppet valve and not a piston. The actuator is a piston.
synaptic1 3 years ago
And why would i buy anyting from you, if it worked, when i can just take a standard bypassvalve and remove the spring, then the valve will be open as long u got vaccum.
Thats all youre grap is, a recirculating bypass whit a really weak spring.
Webrexxx 3 years ago
Synchronic does not have a diaphragm and has a tiered piston actuator that does not leak boost, and is pressure tested to 100 psi not to leak boost. The valve geometry is a pull-type design that seats harder as you run more boost. Try running a weak spring on a diaphragm BOV and see just how fast it closes with boost pressure at the valve face.
synaptic1 3 years ago
Only amatures run whit diaphram BOVs stupid.
All the BOVs and Bypasses i use hav o-ringed light alloy pistons, or, just valve stems like a wastegate whit Oring seat, those will never leak. 100psi, thats like 6.5bars? We test whit factory-standard 10 bars here in sweden.

The restriction is under vacuum conditions. You bypass all of the surface area that is in the intercooler, charge piping and compressor.
synaptic1 3 years ago
Go, fuck your self, i built more turbo charge cars than u can dream off!
You onesly think a hose whit 20-30mm would flow better than the 2" the IC and the turbo?
Do you even know anyting about air flow dynamics and restrictors?
This is, BS! Pure BS. I can hear u opening the trottel less when the valve is closed.
Webrexxx 3 years ago
Hey genius, do you even have a dyno? Under cruising, part throttle loads with vacuum, a twin turbo Z06 only makes 35 HP, how much airflow do you think that requires? Do you know the difference between flow and pressure?
synaptic1 3 years ago
I have acces to a couple enginedynos, rotortest, etc.
35HP uses less than that 20mm, of flow, and thats what i mean, the turbo system haf way less restriction than a small hose.
If it was a 1.5" tube, whit a trottle bypass maybe, i would belive some of it, and that it would make a different on a car whit a Realllly small turbo and IC.
Offcourse when youre taking air from the atmosfere and bypassning the filer u get som results, but when a hose is there, you'll get nothning.
Webrexxx 3 years ago
Come on by, any car with the bypass valve between the throttle and intercooler installed, we'll throw it on the dyno and have you see it for youself. Why do you think that the roots blowers have these built in bypasses, even though they don't have the same level of restriction?
