Synapse Hybrid Bov Review

[newwildchild]

look like that is correct, there also waiting for the flange on the mazdaspeed6 group buy. price list for the group buy

The discounted pricing i got is as follows.
0-9 units $197.10
10-19 units $187.10
20+ units $177.10
Flange is fixed at $22.49
Shipping is $14 in lower 48 states

from the mazda6forum group buy

So far i called the company and they say the main batch is still stuck. That is why i am holding off on doing a full GB until everything is set. I do not want to do it now and find out i am stuck with no flange. Other website might say they have but i really have no idea. I just talk directly with the company yesterday and they are still waiting eagerly for the flanges.
Hope it hits the 20+ target.

So far the list is as follows.

1. kurfgator-No Flange
2. JumpingJackson - Speed 6 Flange
3. aviator79
4. Chucky12
5. MPSdriver - Speed 6 Flange
6. mdduff
7. sgon
8. fireboy
9. Qbert
10 Fountainclimber
11. ynitro56
12. knyghtryda
13. 6derek6
14. MZBuckeye - Speed 6 flange

I am pretty sure I remember him saying he has a leaky stock valve. that was my original point. if you have a leaky valve, it's going to help. I'm not 100% sure that he compared the new one to the stocker, cause I know he had a forge before this one, but I am assuming that is the case. I don't doubt his results. he's been 100% honest every time I've delt with him.

i compared it to stock. I sold the forge. the forge held boost better but not as good as this. The forge still fell off hard by 6k. this one holds it much better.

Ps. My results are exactly as I posted them. The car is way faster with it on. I have no gain by posting these results. No one pays me to do this. Pg sent me a unit to test and these are my results. The thing works thats all I know. LOL

Of course you don't have to post or do anything you don't want to do, but It's a forum thing. When people make a claim on a thread, what usually happens next? "proof? proof?". Just saying...

btw, the 2-3psi sounds more realistic now. Wasn't sure if the synchronic was compared to the forge or leaky stocky. Glad that's confirmed.

driver how does the bov sound in recirc. I heard one sound clip and it sounded stock which is exactly what I am looking for.

 

[driver311]

Similar to stock but a touch louder. Its perfect for me. You can definately hear it outside though. Just not 10 cars away. LOL

ps. Again the best part is how good it holds boost to 6k. 3psi atleast at 6k. Thats a big difference. Ill dyno like I said when i get time. Mx'ing is taking up all my spare time.

Is there any flutter or anything like the forge and is it audible when you shift at any rpm or just when the engine is under high load. I really don't want a loud BOV. I can't understand the VTA bs. The car runs worse and you look like an asshole everytime you shift. No offense to anyone who is into to this, but I like having a sleeper.

At high boost it has that multiple sneeze sound still It sounds nice and is mellow at low boost. These impressions are on my car in VTA. Dread do you have a Standback running VTA? The car used to run fine with a HKS. The Synapse member on Mazdaspeed Forum dot org did admit the valve isn't meant to run in VTA on a MAF application. the anti-stall kit doesn't work that great in my opinion. I didn't know this before hand so I tried it. I am switching back to recirc if I can make everything fit. If not I am dumping this valve to go back to my HKS.

I don't have a standback or BOV

Fitment question for you Craig: how close is the bpv/bov mounting location/angle on your fmic compared to the stock mounting location? I'm curious to see if the Synapse will fit set-up for recirc along with a COBB SRI and stock IC. With the SRI and a stock IC, I had trouble getting the stock recirc hose around this particular intake charge hose when attempting to run a HKS SSQV no matter how I turned the stock hose. It just kinked way too much. I think the only option I had was to piece my own recirc hose together. Also, any chance the Synapse will include a recirc hose for MS3's or is the stock one to be re-used?

According to Synapse, you re-use the stock recirc hose, but need to cut an inch off of it. Looks like it will fit with the stock IC and a Cobb SRI.

 

[dread]

why would you need to cut it? I don't want to cut my recirc hose, I want to be able to go back to stock.

Because it's too long if you don't cut it.

The BOV isn't for sale yet Sleeper. The BOV is huge and does present some weird fitment issues PLM. The Cobb on my car fits great with the BOV, the BOV is sooo close to the hood, but I am mounting it on a FMIC.

 

[daonly1around]

ok, so what do i need to use this when i get my first couple mods, only thing under the hood for me starting off is the cobb intake, and upgrade mount, and either the forge unit, the bolt on HKS, or this if this will work with my my setup

This will work with any setup, from completely stock to seriously upgraded. How much of a performance upgrade you will see at a stock or near stock level will depend on how much, if any, your stock BPV leaks. Either way, with how fast this valves seems to react, I suspect you will notice a difference even if your stocker doesn't leak at all. Nowhere near 28 hp, but a difference nonetheless.

i still dont see adapter flange on their website I'll wait till its avaliable to order mine.

Yeah where the **** is the adapter. It sounds like the valve barely fits under the hood, so I would like a proper adapter.

I've posted these pics in another thread, but here is what the recirc tube looks like when attempting to install the HKS bolt on with the COBB SRI. The hoses were much too restricted due to kinking in my opinion no matter how I rotated the stock hose. You could see it pulling on the intake. I think you'd need to look for another piece of hose with a descent bend to it in order to get underneath the intake with this particular combo.
