Default synapse bov

Anybody has any experience with it.
company who sales them explain that with this bov you dont need to recilculate air from bov back to intake to prevent air vacuum leak
is it true???

I've heard a lot of "Chinese crap" from a few turbo people. If you're going to spend that kind of money, TiAL is an option, American made, great reliability record, and I'd buy from them again.

Or get the standard "Q" BOV and run a pink, 11psi spring in it. It will seal at idle and cruise and still work properly for a long time.

Just a thought: Buy a real fueling solution, or recirculate. The idle surge isn't the only problem.

There is a right and a wrong way to do things on the cheap. Spending a ton of cash on a blow off valve that wont leak because you don't want to pony up for a real ECU is pointless.

If it leaks at idle and cruise it will let dirt into the motor. My very first UOA had a bunch of silicon in it, changing the spring in the BOV fixed it.

I've only read about these I personally have never seen one in person. I just approve on design. In theory it sounds like it should work. You could always run a filter for those who don't like the valve open on cruise and idle, or do the recirculated method.

I'm not saying its a good idea to run a leaking BOV. But running a VTA valve because you "don't want to recirculate" and are running a stock ECU is a poor excuse to spend the cash. At such low boost pressures, just buy a stock valve from an audi and recirculate.

No sag, no leaks. Win.

You will most likely crack that manifold. It may hold up if you brace it properly. Everything else points to a fairly tame bandaid setup, which is doable, but not advised. Just save the cash for now and pick up a bosch valve and recirculate it. You'll appreciate it when the car doesn't run like crap between shifts.

sounds simple, just put small air filter on synapse bov and it should work?

My recirculated Bosch valve still made fancy noises.

if you want to use the synapses bov with the AFM still in place you will need to run their check valve they have for it.

you can use that and recirculate the synapses bov until later, than you can run it without it once you go standalone
