It's a BOV...having a fancy word with it isn't going to make it any better than any other one on the market. It's still going have the same effect as any other BOV.

That couldnt be further from the truth. Blow off valves range from terrible to really really good when it comes to functionality. Many of them leak, some leak really bad. Some leak at anything past like 17PSI, others, like GFB valves, tend to leak as early as 7PSI. Some dont release properly consistantly.

Then there are others that hold like a rock, and vent correctly.

All blow off valves are not created equal by a longshot.

But yes, I would bet on the syncronic being no better or worse than the average. It could be good, it may suck.

Like I said before, remember the "badass bov" thread from a few years back? It was inspired by the new (at the time) worx bov. An entire thread with people who put it on, and went PSSSSSHHH and thought that made it better than any valve out there.
Meanwhile they leak like its going out of style. They arent badass. They are bad, and they are ass. And I dont think that particular valve is even on the market anymore, and its only been a couple years. No one phases out a product like a bov after only 2-3 years. There is a reason its not around anymore.

after alot of effort i got one installed on my stock 05 wrx.

http://www.clubwrx.net/forums/showth...ght=synchronic

overall its a great bov and there is absolutely no compressor surge, although i do recommend the antistall valve with it, which prevents the bov opening at idle and stalling.

Its their method of limiting the amount of idle air bieng released, and sucked in on idle, s0 watching my boost gauge it will go from -20psi to a fall in rpm's less than 1k and the vacuum going to -10psi so its introducing a method to limit the air entering and leaving. Ill be getting one soon and ill let u know how it works..

But the sound it makes is amazing.

well im less concerned with the sound , if thats what i was going after id just dual out ssqvs, but im after no surge and no premature opening, which the title seems to be owned by tial , even compared to the hks racing valve type 2 the tial can handle double the psi according to info ive looked up

Whats nice about the synchronic, no tuning necessary, it runs of ur vaccum and ur boost, which makes perfect sense. And i havent had any boost or compressor surge, i finally got her perfect, with the synchronic bov i recommend a mbc to achieve full boost effectively although the stock one can work.

You's didn't understand what I was getting at. At the end of the day, it's a BOV. Regardless if it leaks or not, goes PSSSSSHHHHHT any louder or quieter than most do.

So really what makes the synchronic so damn special? What awesome things can it do that the factory BPV can't do?

the claim they make is that there is 0 surge at any time, and the reaction time to the valve opening is very quick especially compared to push type bovs, but my worry is that they may leak more or open prematurely

why use anything but the tial bov then?

the tial bov is awesome. holds crazy boost and reacts very fast. the only thing is getting the right spring so you dont get compressor surge. the synchronic looks like a pos that will probably break in a week.

doesnt it tho , it looks like a plastic ssqv that would explode under my 27 lbs lol.. im probly gonna stick to the tial get the 11-12 lb spring and shim accordingly.. but i just wanted to see if anybody has had som extensive hands on experiance working with this new bov

i was asking about other bovs because def all are def far from being equal... even high names such as hks are not as good as another .. i mean hks vs worx or turbo xs and perrin the high name list goes on..

they're so good they had to start a campaign on youtube slandering tial to get press

any company that feels the need to state another PROVEN company is bs by rigging the setups doesn't deserve any money.

Bumping this thread.

Well I have to say that my car was the one that you see in the videos.
Here it is before I made a reverse manifold in my garage


And then after I hacked up the piping


The Tial BOV I still have has the wrong spring in it for what my car should run. The reason for this is because I had all the piping you see in the first picture fabricated off of a turbo XS FMIC kit. I got the 30R on there and Nick Deblasi (STEALTHWRX) (Green drag car) fabbed up the kit for me when he ran his own shop a couple of years ago. We can see that a TIAL BOV is not a Bolt-on peice. So he welded eveything together and I was enjoying my car until I heard about compressor surge. and I was thinking to myself that this was happening to me. I tried to take the spring out of the BOV but there were no markings or colors on the spring to tell how stiff it was. All I knew was that it surged, So when I went to Synapse Engineering witch is local for me I went there to test the 40mm wastegate and when I got there the owner asked if I wanted to run the BOV too with the promise of no more surge. So I put the thing on with the tial adapter flange and what do you know it worked beautifully. There was nothing doctored on the bov to make it not work but then again there was no attempt to put a softer spring in there either

Here is the car now
