  • it sounds sloppy

  • Did this guy just put a non connected bov vs a connected one to see which is better? it doesn't matter how sensitive it is, you know there is a huge difference and isnt a fair comparison. bias review

  • Good vid. Nothing wrong with comparing products. It's a competitive market out there, no problem at all with pointing out an opponents flaws that's on them. Good vid

  • Wait im confused.. is this a turbo S2000 or a lawn mower??

  • Just a shame your "company" is threatened by the liked of HKS, Blitz and greddy.

    Shame you have to dump all over their products.

    Pumping compressed air through your product, slagging off another bov at the speed it vents.

    HKS SS seals better and doesnt let shit in... which yours doesnt.

    HKS is also piston operated.

    HKS has NEVER let me down.

    HKS are proven to work, and work well.

    I see no other companies using or apraising your product.

    Stop slating other products and play fair.

  • The Synchronic line of products are available by registering at SYNAPSEENGINEERING*COM/CART, use referral code YOUTUBE when you register and be eligible for limited edition designs and market pre-releases

  • hmm... it still surges when it moves...

  • LOL, seriously I own a 95 TT supra, an 89 supra. The 89 puts down 595hp, and the 95 is making 754hp. I don't think those are naturally aspirated pieces of shit.

  • @synaptic1 Dude, it also lets in un-metered, un-filtered air and debris!

  • Seriously , you dipShitz are judging a product that you haven't even tried, don't knock it till you try it, and if you're still adamant about saying that it's a piece of shit product based on the fact that it doesn't go woosh wooooooosh excessively loud, then you need a swift kick in the face. this guy has something going for him, you have to start somewhere, what have you done?

  • kids R tools these days, they need to have the loudest bov on the market so they can show off/and or use it as an instrument to help aid in hollering at DA diMe pieces; ...

    chad: sup brian, thats a gnarlly Bov you got thur brah"

    brian: yea, its pretty loud man

    chad: yahh, well.. mines louder

    brian: haha, i seriously doubt that dude

    chad: ehh lets just go drive by some chicks maybe our bovs will impress them enough to approach our cars.

    brian: yea man high 5 lets break some necks

  • sounds like its surging at the end lol

  • I have this on my s2000 and it is actually a very nice blow off valve. If you heard it in person I don't think there would be so many people complaining

  • man, this sounds kinda like the ford commercials, someone came up with something new and is trying to compete with all the popluar japanese products except there are some other good american products that isn't the cheap piston type. everyone knows that you can adjust all the blow off valves you tested so there would'nt be any compressor surge. greddy and hks have a lot of r & d and have been selling them for years, don't need to try and compare to them, it just makes you look needy like ford

  • why is this blow off valve so special? My stock saab had one that did the same exactly thing from factory. It had a vacuum line running to the manifold and it opened everytime there was a vacuum in the manifold (aka throttle plate closed)

  • Engine's got no power.

  • stop, the engine is choking >.<

    poor engine

  • what type of blow of the the stuttering one?

  • I usually use the term sequential blow off valve rather than synchronic. I think sequential is more used but i may be wrong.

  • Compressor surging is bad... and yet this guy loves making it happen :D

  • @peepeevagi even after "fixing it" it still sounds like it's there in some shots when he's under the hood revving it by hand

  • HA HA HA HAHAHAHA HAAHAH LOWTECH EQUIMENT DIE BY FOOL WAY WITH TURBO AND ARMY TECHNOLOGIES.

  • cool.. u sure love to rev that thing eh...

  • :_(

  • I bet that impress  the girl on your first date..

  • so what is this a cheap blow off valve??? lol go buy a hks, ricer

  • why isn't the ssqv hooked up to charge piping as well?

  • hey great vid mate just wondering how did you get you valve to churp like that in your drive by? ive installed on my r32 GTR and it just sounds like a hiroic ppsssshhhhh even on low boost i dont like it!! what ports are you using for vacuum on the valve and are you using anti-stall kit? thanks

  • This sounds like a horse with down-syndrome.

    Poor engine.

    Shit BOV

    & The worst company.

  • Comment removed

  • how come your timing is delay?

  • poor s2k;(

  • There is no vacuum anywhere, it's negative pressure. Go and read your school physics books, synaptic1.

  • Your valve retainers are cracked and your about to drop a valve.

  • YOUR GASSSSS!

  • that car engine sucks so fucking bad!

  • those injectors are really really loud...

  • so this device allows non filtered air that hasnt been read by the MAF into your engine,which on a turbo car increases risk of DET (melts pistons) . this makes no sense atall it would ruin your engine when the point of a blow off valve is to protect your engine??

  • sounds shit

  • wow.. dude is a fucking faggot.. why would you want your bov to sound like that?? AKA... SHIT!

  • @TaekwondoGuy86 because the purpose of a bov is not to sound nice contrary to popular oppinion... its REAL job is get rid of excessive boost presures that could be dangerous to the engine or transmission.. children these days i tell u...

  • OK really?I mean you say your BOV will fix the problem of sucking in air?What BOV sucks in air?The point of a blow off valve is this when your in boost and let-off the gas it opens to let the build-up boost out not in!Your trying to sale this crap to someone that know nothing about cars or how a turbo and BOV works but take it from me,go to HKS and get something that works.

  • no pressure doesnt keep building and building in an auto car. thats what the waste gate is for

  • Dude! u need that pressure. By letting it go early your loosing the turbos power response or recovery rate.

  • is it me or does it look like the blow off valve is open at idle

  • okay I have the intercooler piping with the hks flange. I have that for the the bov too. How do I get the bov to stay on the piping? it fits perfectly with the ssqv adapter but how do you get it to stay on?

  • c ring, should come with the kit

  • c ring, clip what ever you wanna call it, you need special pliers to put it on

  • let's insult. doublemcnasty, because you're a girl! rubiox08, you've written the truth. doublemcnasty, take notes on rubiox08, because you're a girl. mrslowskyline, you impress me most w/ your idiocy. mrslowskyline should hook up w/ doublemcnasty because she states that she is a girl.

  • surge doesn't cause the compressor to spin in the other direction. Imagine the pressures involvd in that. Your turbo is spinning along at 100,000rpm. it stops and spins the other way? It blows apart. The sound is air chopping against the compressor blades. The wheels do NOT spin backwards.

    I won't buy a synaptic blow off valve because their official movies make such outlandish claims about backwards spinning turbos = they dont know shit.

  • @MrSlowSkyline

    you sir are a fucking idiot... you just said yourself that its chopping against the compressor blades. YES it is chopping because its trying to spin the blade backwards hence CHOPPING.. think before you speak its not going to literaly spin it backwards but its trying to hence the CHOPPING...

  • u need to sell that s2000 and go back to school thos are 2 diff bov's and there not look to work that same but they ill do that same job u can read an book out there about cars and they well tell u that

  • this guy sounds like he's high trying to explain that

  • this guy is a fucking jackass how the fuck are you going to compare two different bov and one is hooked up to the car .....really really now i dont car what you say the one that is hooked in to the car is no shit going to respond fast ....WOW gotta love people that think they know what their talking about .......

  • @ doublemcnasty suped up srts dont last. my friend already spent like 35 gs on repairs for his in 2 and a half years. 3 times the amount its worth. hes stage 2 mopar with all its supporting mods

  • what shitty throttle response

  • Well,dudes,I bought a SRT-4 brand new back n 04,broke it in correctly,then after 2,500 miles I started losing boost.I knew this was a crock,so I took it 2 the dealership where they proceeded 2 insult me(because Im a girl),and because they suck!!They said nothing was wrong,its normal to lose a few lbs of boost.Wtf ever,got rid of that damn thing,and found out that the boost actuators were faulty on em....Mite wanna check into that....And Mopar does sell "aftermarket" diaphragm bovs.

  • GET A HARDTOP PLZ

  • @Lulubug87

    Compressor surge is what happens when you create too much positive pressure on the intake side of the engine via a compressor, when throttle is released the pressure pushes the compressor in reverse. It's actually very simple. In most cars it is caused by the pressure from the manifold to not be released fast enough. Off throttle the pressure backs up in the charge side and needs to escape. If it can't escape your BOV as fast as it can via the turbo.

  • Thats because OEM turbo systems use bypass valves, not blow-off valves, that recirculate the relieve pressure back into the , compressor to manifold piping. Hence, they OEM turbo cars dont have that blow off sound. that doesnt mean that the positive pressure is left to shoot back into the compressor. Turbo surge is a real thing.

  • What is compressor surge...it is good or bad?

    Someone kindly explain for me thanks...i really wanna know...

  • @Tsukuy0mii

    It is bad. You do not want excess pressure in your charge side coming back through the turbo, that's what your BOV is there for.

  • poor engine...

  • u prob drive a chevy tahoe

  • @jezzetv ACTUALLY I own one of those too, what the fuck does that have to do with my comment though?

  • @23027 ppl who put down jap cars are usually american muscle lovers thats all. I dont see how this is a poor engine?

  • That's no good, a recycling system is a lot better keeps the turbo spinning in between gear changes. I had one as standard on my 89 Intergale!

  • @mylaser91 You can ruin your turbo all you want. The man is right. and just because the other BOV is bolted down it makes NO difference in the pressure....

  • I have so many questions on this. Does this help relieve pressure on the engine block a lot better than a normal one? Also, does this let the engine suck in more air? Does it give more power?

    Sorry for the overload on questions, it's just I think this is a great idea. Also, turbocharged carson a normally N/A car put a huge amount of stress on the engine and and make it ruined after a while unless it isn't built up. So does this help solve that problem?

  • @billygoatdawg081992 no when a blow off valve opens it releases preasure in your manifold and no it does not give more power maybe a tiny bit off boost but they are used so your turbo does not blow up

  • also for people who get surge.. they are not adjusting their bov correctly.

    My HKS SSQV has ZERO SERGE regardless of low or high boost.

  • I respect your point of view. But the hundreds of guys that have bought our HKS adapter and will never go back, demonstrate to anyone that they have found a definite advantage with Synchronic over the HKS.

  • hundreds of guys dont know the ins and outs of a BOV. If you respect our point of view, dont knock other companies that put out a great product for a reasonable price. The bottom line is you stil need a recir kit to make your BOV work. You cant install recir with out drilling or putting in a new hold after the MAF sensor. Thus its more expensive to install your kit and needs more custom work. The

  • They don't have to know the ins and outs of a BOV. They bolted on Synchronic, and it was far superior in performance to what they had. What else is there to say? Almost all factory turbo cars with MAF already have a recirc.

  • would a factory bov rob boost presure?? have a srt4 and if im lucky ill get 10 psi if im lucky when im sposed to get 11 to 15

  • @speedoracle I wouldn't say that you may be one of the hundreds.. But I will add to your knowledge. You need to use a bypass valve, or a BOV with a recirculated setup only on MAF metered cars.. What about cars that use MAP sensors? The only reason you don't want to release to atmosphere on a MAF setup is because the air is accounted for already, and you need it to stay stoch.. A MAP doesn't measure the amount of air coming into the system, so could care less if it's vented to the atmosphere..

  • "50% of all people that are buying Synchronic BOVs have already spent money on another brand and choose to eBay the inferior brand"

    lets not KNOCK awesome brands out there. Non of them are inferior. They work with stock ecu and aftermarket ecu.

  • Synchronic is designed to be used re-circulated with MAF cars.

  • does recirculated kit come with the BOV? or do you need to buy it extra?

  • 1.25" comes in the box standard.

  • comes with recir kit on all your bov

  • My HKS SSQV works just as fast. and is actually closed at idle thus NO VACUUM leak.

    You BOV makes a HUGE vacuum leak for those people who are not running speed density or stand alone ECU.

    This setup is not good for stock ECU since stock MAF sensor already calculated the right amount of air but with this BOV, new additional air is let in and the car will have unmetered air and run like crap if run at all.

  • In re-circ, you can actually pick up improved throttle response by having the BOV open and in full re-circ. It is simply a different philosophy and not for everyone.

  • I think your company should send out the correct information before claiming its the hottest BOV out there.

    My HKS Gen1 SSQV reacts just as fast and can be used on a stock vehicle with stock maf sensor and ecu because the valves are closed at idle.

  • Sound is really the only thing that you should look for in a bov. The HKS performs perfect every time.

  • When you bolt on the Synchronic BOV you will realize what an improvement in throttle response a well designed BOV can make in any turbo charged system. This is the reason why 50% of all people that are buying Synchronic BOVs have already spent money on another brand and choose to eBay the inferior brand, because performance is what matters to our customers.

  • sweet a guy that stricly goes by sound go do some research on the both bov's synchronics is a way better bov

  • The HKS super sequential is way better than this piece of junk

  • nice honda

    nice blow off valve

    nice knowledge

    greetings from chile

    bye

  • Omg lol, this is so fucking rigged. When a blow off valve actuates(opens) it isn't just the diaphragm that pulls it open. It is also the vacuum that is in the charge piping. That is why the HKS SSQV wont move in this video. Fuck you Synapse, you bastards rig every video you have. I hope you go bankrupt, mainly for downing other products that have been proven countless times to work the best.

  • @mikethedick Sure it is rigged. BTW, there's no vacuum in the charge pipe.

  • @synaptic1 Run some real boost and test reaction speed. I don't think people buying the HKS SSQV are out to run in "Economy Mode". I'm certain of two things, all the other main stream valves will open just as fast and sound better than that little Queef your valve lets off.

  • @synaptic1 Here I am a year later standing true to the slander you have in this video. "When a blow off valve actuates(opens) it isn't just the diaphragm that pulls it open. It is also the vacuum that is in the charge piping. That is why the HKS SSQV wont move in this video." You like to rely on the terminology of the "Hated" or "Hater(S)," and associate this with your company. This product is not inferior, it is a ripoff of HKS's patented design. You also slander them in the video. Go Bankrupt.

  • @mikethedick If there was a VACUUM in the charge pipe, there was no need for a BOV ;-).

  • @mikethedick last time i checked they are using a synapse synchronic you jackass and there is no vaccuum in the charge pipe like he said you dont know shit about cars youngin

  • @Jlizel Care to elaborate on a shitty reason for me building eleven engines that have all held 700-950HP. Those were all built ranging from 2003 to 2007. They are still being used in this day and age. So please go drive your KIA Rio with 90HP please.

  • @mikethedick im sure you've built engines you just a rich christiansen pinks fanboy. i dont own korean piece's of shit. your all talk keep to your naturally aspirated outdated american pieces of shit. you dont know anything about forced induction based on your previous comment you ignorant hillbilly sister fucker

  • i have a question.. will BOV work on stock car?

  • depends, ur car has to be turbocharged, and u may need to change a peice of ur charge pipe to one with a b.o.v flange

  • ho a blow off valve is when u change gear it makes a sounds ? lol help

  • yah, anytime u let off the gas. the BOV will release and spit out all the pressure that the turbo builds up so u dont blow your engine.

  • its not the changing of gear, it the fact you go off throttle before you change, the bov vent the pressure as you throttle shuts.

  • As you probably already know its when you let of the gas. Thats why you only see them in manual cars cause if you put it in an automatic even though the gears are shifting you still have your foot on the gas so the pressure keeps building and building till you blow sumthing. Unless theres a way of letting the pressure out without me knowing it.

  • how bias the other BOV is made to work WITH the spring adjusted correctly and not on the lowest setting

    maybe you should compare them when theyre set up correctly

  • A mi no me gusta una valvula con lo bonito que suena ese coche.

  • Fuck your stupid torqueless piece of trash.

  • hahahahaha

  • lol its not torqueless anymore its got a turbo. u dont fuck with turbo'd s2k's man this is comin from a kid with a 30r sti makin 340whp

  • that's pretty sad if you only have 340 whp with a 30r...

  • yall sound like granmas fighting over cock

  • sounds like a retarded duck quack

  • sounds like it would get annoying really quick

  • Flutter is cool tho..

  • Those BOV's sound like shit.

  • Turbo's cannot spin backwards and this is not compressor surge, it doesn't even sound like wastegate chatter, it's charge air being forced back through the turbine and chopped up,

  • yeah but the sound is the air TRYING to force the turbine to spin backwards, and getting chopped up.

  • Air doesn't make a sound when it's trying to do something, only when it is doing something, the sound is a pulse created by the speed of the turbine, size, pitch and shape, and the resonance volume within the turbine housing, and possibly the intake pipe feeding the turbo.

  • lol?

    the TRYING to force the turbine backwards IS the air doing something, ie, hitting the blades which are spinning in the opposite direction in which the air is trying to, being chopped up.

  • The air isn't spinning, it is to all intent and purpose it is a lamina flow hitting the blades, trying to spin the blades backwards implies it is exerting a torque on the turbine, torque has no sound, unless something breaks. It's the disruption caused to the air flow that gives the sound.

  • ...

    it's almost like you're trying to blind me with technical terms.

    and yes of course it's the disruption to the air flow that is making the sound

    the air is disrupted because the turbine blades are moving forwards, the air wants to move in the opposite direction to said blades..

    which is what i've been saying the entire time.

    and torque has no sound.. that's a stupid statement, torque is a moment of a force around a rotating mass, nothing more, nothing physical itself.

  • Torque is very physical, and it's a tangential force applied at a distance from an axis, it doesn't need to be rotating.

    Anyway, yes the noise is caused by air hitting the blades, which, if unopposed would cause the turbine assembly to counter rotate.

  • no it has to be rotating lol.

    Torque, also called moment or moment of force (see the terminology below), is the tendency of a force to rotate an object about an axis,

    can't have linear torque.

    and torque isn't the force itself, it's the ability of the force to rotate around a point.

    sure, from wiki, but it's the exact same in the textbook i have. i learnt about it for long enough too :(

    i'm too tired for this

    and we're WAY off topic.

  • An object does not need to be rotating to experience torque, it's simply a turning force imparted onto an mass. It's possible that torque can result in rotation but not always.

    I've been studying it for years too, I share your pain man,

  • i love this sound!!!!!!!!!!!!

  • 1. a lot

    2. garrett, ihi

  • hey guys, can u tell me the price to install the turbo for my car? and what type of brand is the best....plz guys

  • synchronic or tial

  • My civic running without the air filter cover sounds way better.. maybe if you revved it higher....

  • you sound stupid as fuck

  • like the way your brain thinks?

  • I dont know, Im pretty partial to a Greddy type RS...even if this one works better, I wouldnt be happy with the sound.

  • is that a rod knock or ur valves ticking u should check befor u post a video were we can hear it perfectly

  • turbos only spin in one direction dude. it's the sound of the air being pushed back through the fins and the fins cutting it up.

  • surge sounds so good. if you shift hard enough you can keep a bit of boost when you dump the clutch into the next gear

  • good video man! very informative!

  • the valve stays open on idle, and part throtle. what filters the air? any bov with a weak spring will react fast, but will stay open on vacuum. it's a compromise... a bov should only be open when there's air coming out, not in.

  • i dont hear any blow off valve haha

    you make that thing sound so pinner

  • sounds like ya got some knock.. ?

  • what the fuck? economy mode? and do we really need to hear you do the same damn >2000rpm rev 200 times on that garbage blow off valve?

  • yea man right on....fuck that was funny

  • sounds like u got a little bit of valve chatter

  • I love how all you assholes comment cuz u think you know everything. When really you dont know SHIT

  • nice 5*

  • yea man you guys are stupid as hell,all honda's sound like that its the valves?lol i have an 03 s2000 mine sounds the same.you you guys even own honda's?DOHC?

  • sounds like shit

  • i like the sounds..."seses"

  • LOL more like VROOMFFFTSSSSS

  • car has no power and its a terrible bov

  • car has plenty of power and its a great bov

  • so why is compressor surge bad?

  • Because the turbo builds boost in the intake circuit while you're under throttle and then when the throttle blades slam shut, there's all that boost and no where to go. It's only path that it can take is back through the turbo in the OPPOSITE direction, and that is bad. It's extremely hard on the turbo and the motor.

  • it's not.. a few "elitists" made this claim in an attempt to be the only few with the neat sounding cars

  • My turboxs bov is a full piston bov with no diaphram and it reacts just as fast as the synchronic.

  • Actually you nit-wit that is Compressor surge....you usually if not ALWAYS get compressor surge by closing your throttle plate very quickly and the excess boost forcing it's way out of the intake turbine of your turbo hence why it makes that noise...

  • thats not compressor surge

  • yes it is...

  • well it's not the sound of pressure forcing the turbine to spin the other direction, the turbine does slow down, yes, but never changes rotational direction. The sound comes from the pressure waves created when the turbine is trying to push more air than the engine can take. That's why you see "anti surge" housings with ports in the inlet designed to break up the pressure waves. Has nothing to do with the turbine spinning the other direction.

  • HKS are much better than this, compared to HKS this is a cheap peice of crap you would buy from halfords....

  • Have you ever actually looked at an HKS? They are die cast like cheap toys, it is made of the same crap metal that Matchbox cars are. The valves are plastic. The Synchronic BOV is billet 6061 aircraft-grade aluminum that is individually CNC machined within 0.03mm tolerances. There is no diaphragm and the valve is solid Aluminum machined from billet.

  • I know HKS has been around a while. But you're in the UK, we're in the US, and the product isn't "new" there are thousands here in the US and a healthy chunk of them have removed their HKS that they have already spent money on, just to put on a Synapse and are impressed by the improvement.

  • Do they "specalise" in cars or do you just play need for speed?

  • does the bov happen when you press the clutch in ?

  • Only If youre actually driving under load, when you press the clutch in it closes the throttle plate.

  • okay can you PLEASE say it in an EASY way ?! i didnt understand anything ,.. i wanna be a mechanic and im 14 .. so i gotta lean alot ..

  • dude u should download urself a computer program dat is wat i did and its really cool im 16

  • eh okay whats it called ?

  • its called cad i bought mine but its good man

  • U need to learn about engines and how they work before u learn about turbos.

  • i know alot about cars and im 14 and what really helped me out alot is watching ALOT of youtube videos of random car stuff! lol im serious just look up like street racing or something and they normally talk about their cars. this might sound stupid but it really helped me. hopefully it willl help you

  • kid, although watching youtube vids might help you understand some of the things, it is undeniable that many other things require a hands on experience and years of experimentation to fully understand, so dont miss your oppurtunities... Some times, getting outside your house and observing cars at events might be the better alternative.

  • i know. but over summers i go help my dad out at his shop so im getting hands on also haha
