(bang) I wanted one of these... I guess I jumped the gun too soon... 
Synapse Hybrid Bov Review
- Thread starter driver311
- Start date
only problem is that the boost decreased on the car in the dyno by 2-3 psi so the hp gain is most likely from the octane booster. Its amazing how much hype a product can get from a b.s. dyno. How can you make claims like that with all the variables that are not accounted for. Notice they don't show you boost after the BOV was installed but its more than 2psi less. I asked for the charts and they posted them on another forum.

Wow you're so negative, pure boner killer. Whether or not it gives you an additional 28hp isn't important, functionality and reliability is. There are multiple reviews out there stating this device works extremely well and yes of course the company that is endorsing their own product is going to say things to their own benefit, that's how they make their money. I think it's good that some people are taking a different path away from the HKS SSQVs and the Forge and trying something new.
I am just being a realist. I like this bov in all honosty but I don't agree with this marketing trick. The dyno is not controlling for important variables and I cannot accept those results, especially. Considering the boost graph showed a 2 psi loss in pressure after the bov was installed. I am looking forward to more dynos.
yes this brings up a good point, driver311 got 2 or 3 psi more with the bov, the dyno shows 2 psi less, but a 28 hp gain....... I like this valve too, but need this explained. If the synchronic people are watching this board, pls post an answer or do a few more dynos. If the product really does what they say it does, the dyno will prove it.
here is there explanation from another forum sorry I don't feel like posting the charts.
"This first chart shows the boost line in Blue. Horsepower is in green. The solid line is the run with Synchronic BOV, the dotted line is the baseline run. It looks unusual how we're making more power with lower boost. But this is the same thing that we saw with the Corvette and Bosch DVs.
It sounds counterintuitive that you are running less boost with a BOV that doesn't leak. However, when you have a leak in the boost system, you unload the compressor, effectively overspinning the turbo a little. This means that the turbo is probably not operating in the right efficiency island of the compressor map and making more heat. More heat = more pressure. More heat also means less dense air and lower molar quantities of Oxygen. At the same time, the exhaust manifold backpressure is likely to be higher for that given shaft speed RPM. Which means worse exhaust scavenging and dirtier charge = lower BMEP cylinder pressure."
I guess it would make sense, but the turbo was within its efficiency range with the stock valve so its not pushing hot air.

I agree with that statement. The better way to get in touch with them is to find the mazdaspeed 3 bov review on youtube and post a comment in the form of a question. They're pretty good at replying.
if you're buying a bypass valve to pick up horsepower, I'm laughing.
also, if you don't have a leaky stock valve (I didn't) nothing is going to change, unless you plan on running more boost eventually. you'll just have a more robust, more reliable, nicer looking, probably cooler sounding bypass valve.
also, if you want to know what it's going to do on your car (these speed3's all seem to have a personality of their own) just buy the thing and put it on. I am sure if you don't like it, you won't have a problem getting rid of it. everyone seems to have a boner for it right now.

google turbonator dude ....you'll lol

My thoughts exactly, but driver is claiming a 2-3 boost gain from stock to forge to now this, "synchronic". To good to be true?? I hate to be a doubter cause it's such a negative thing to do but...
