Synapse Hybrid Bov Review

I don't get it, its just like when the cobb sri came out and everyone sold their intakes to get the new one. Its probably a good bov, but there is nothing that suggests its better than any that were available before. Yes the video is B.S. but right after it was posted on you tube, every mazda forum had several threads about the synapse BOV. Shows you what some bull s*** dyno graphs can do for a product.
 
yeah its def not like that at all !

So for someone replacing their stock BPV (not replacing a Forge), would the performance gains justify the $250 (valve, shipping, flange)? I'm not as intersted in the noise it makes, or the look it provides under the hood. Rather the potential gains from holding boost better/longer etc.

The cost plus the ease of install makes it seem like a no-brainer if the above gains are realized, right?

Or is there another BOV I should consider, keeping in mind I'm not interested in sound or appearance.

I guess this is potentially a larger question, and could be more broadly a "bang for your buck" MOD question based on performace.

my point in all this is that.... If you like the performance of the FORGE but the want quietness of the stock set up, and feel of the stock set up this valve is a good choice..

If your looking for a moderate price and performance get a forge IMO (as long as you dont care about sound) you will be happy

If the Synapse is +1 on the Forge (from your experience), wouldn't I be better off with the Synapse? Is there a big price difference between the two? I'm not cheap, just want the best value, if that makes sense considering the product.

Yes there is a big $ difference the synapse is about dubble :(...... the +1 is IMO i had the forge for a while and liked it still do if you are in a BOV/BPV market you cant go wrong with either, FORGE has a +1 on the fitment and style IMO...


Alot of people frown at the noise the Forge makes. iI didnt mind at all but it is nice to have a stock sounding bov again that performs just as good if not a little better then the Forge.....

***To people who have the Cobb SRI fitment is tight using that intake put that on the CON list ......

the forge sounds whack! thats my opinion.
im very big on value too, but with a good mix of performance and overall quality. i like the turbosmart, but it was too expensive imo. everyone and thier sister has HKS, Greddy is also old.
we'll see how it plays out. im very picky on how i have my things
 
Yes turbo xs seems to be good, but I keep reading reviews that say the quality sucks and I have listened to sound clips and it sounds pretty loud. I want a valve that sounds stock but works better.

Sorry for my ignorance.....but what's "IMO"? So the Forge is a better fit (pressumably an easier install) and half the price ($159 on mazdaspeedstore.com) with very similar performance increases over stock. Thanks for your candor, perhaps I'll avoid the hype and try the Forge.

Can you expand on "whack" (i.e. tinny, too loud, etc)? The sound clips I've heard sound similar to stock (with MS CAI), but the speakers in my office probably don't have quit the dynamic range to differentiate.
 
Forge sounds like the old Mario Bros game when you jump to hit your head on the box with the coins in it.

The Synapse is a PITA to install. I have it but am not a huge fan. It is barely better than anything else that doesn't leak. I wanted one for like a year now so I jumped on it. I was dissappointed as the valve can not function as a VTA valve on our cars (mine saw 10 afr's at cruise and 17 afr's under boost).

Sweet crap i gotta hear this! Does anyone have a good sound clip. Oh and IMO mean In My Opinion. IMHO just has Humble thrown in there. Took me a few minutes to get that the first time too. PITA threw me for a loop too. lol.

That is an unusual sound!! I'll check around for sound clips. Did you replace another bov/bpv with the synapse your running know, or was the synapse your first after market bov/bpv? Just wondering if you had something previous that you preferred to the synapse.
 
Whats IS a BPV and it doesnt cause the jerking inbetween shifts from the system giving to much fuel because it thinks theres more pressure than there is? Or is this not the case? I'm noob to Boost, too much honda lol

BPV=By Pass Valve(recirc only)

Correct!

A LOT of people have a problem with the sound the forge makes thus shying away from it. I didn't particularly like the sound either but felt the performance was worth it. SO to me the Synapse is great im getting great performance and stock like sound and drive ability...

Synapse:
If you have the funds and don't mind an actual install vs. (hot swap) i recommend it...

P.S. DON'T BUY THIS THINKING ITS WILL GIVE YOU 20 MORE HP!!!!! its a great increase over the STOCK BPV but if you have a good valve already and like it the synapse wont impress you much more..
 
the forge valve is kind of annoying. if I had an extra 200 bucks int he bank that I didn't know what to do with, I'd get the synapse for the heck of it.
