Synapse Hybrid Bov Review

[driver311]

First off I wanna thank pg for hooking me up with this badboy. Looks dope for sure but how does it work?................ FACKING SICK!!!!!! My car has been hitting around 14-15psi max in 3rd and 4th gear and touches 15-16 in 5th and would fall off hard in every gear to 11psi by 6k. Now its a whole new car. I hooked it up recirculation. It has the option to go either way. Im hitting 16-17psi in 3rd and 4th and it touches 18psi in 5th now. Car holds boost much much better. By 6k Im still over 14psi in the upper gears. Thats much better than before. I took some pics for you guys to see this badboy. Enjoy

Thought Id throw this little one in to.

Its also built like a brick s*** house. I have one sitting in my garage right now, lol. Its heavy as hell, it looks like I could drop kick it against a wall and let it drop the to the concrete floor...and the BOV would win.

[sk00terz]

It takes a bit of trial and error, and you have to snip the recirc hose a touch, but it'll fit. You need to get one of the APR flanges, either the GReddy or HKS, and then a flange that mounts from the valve to the APR flange.

i wanted ot get this piece before i got my hks.

If anyone is looking to pick one up, shoot me a PM. I have all the needed hardware, and it was only run on my car for a about 100 miles or so (three days of commuting).

That's a big difference in psi after only switching valves. If possible, do you think we can see some vid clips or charts? Not another one of those "doubt you" posts, but it sounds too good to be true. Thanks. Nice looking piece nonetheless.

I'll let Driver311 speak for himself, but its a pretty well accepted assumption that the stockers leak and loose boost up in the top end. Plenty of people installing new BPV/BOVs have shown holding a pound or so more of boost all the way through 5500/6000 (depending on a CDFP).

 

[driver311]

I dont know what to tell you guys. I picked 1-2psi across the board easily. Up top maybe even 2-3psi. Holds good.

The valve is as fast acting as they say, I hold more boost also. I am running vta and may be having a problem with the anti-stall kit sealing or leaking. I tryed to fix it but haven't run the car since Saturday to verify proper operation now.

My stocker leaked!!! I gained one solid psi and spike at a solid 20. With the stocker, it was spiking all over the place, 17, 18, 19...but now I get a solid 20 and settles down to 16.6.

In addition, the boost builds up instantly between shifts now. With the stock valve, the boost built up progressively in between shifts. The stock valve reacts too slow and leaks...

Definitely more responsive since I upgraded my BPV!!!

Upgrade that BPV!!! (2thumbs)

I also wanted a Synapse, but I don't like to be the Guinea pig for new applications... (lol2)

 

[Craighjr]

311 and I both have them installed. Your not the test pig now!

I wish I would have known that before my HKS purchase... (thought)
Though I love my HKS!!! (2thumbs)

 

[tru-boost]

you gained that boost over the stock valve or a FORGE ? i thought you had a forge on it at one point ??? i saw very similar gains when i switched to the forge.

Be happy mine runs like SSSSSHHHHHHHIIIIIIIIITTTTTTT!!! I have a video that I will post tonight. I have both vac ports on top to the manifold nipple where the stock one goes, and the boost only port goes right to the compressor cover where the wastegate line comes from. Any ideas whats up? I am going lean as hell and sputtering while on the gas after a shift.

Are you running VTA?
