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???

Stock ecu+maf

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.

I got you, but I want to install vta bov, and tial will fix the problem with air leak at idle???
cauz i dont want to recirculate air back to intake

I see only one way without extra piping is install hks sequential blow off? am i right?

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.

I want to switch over to the - Synchronic synapse when I switch over to my over radiator intercooler set up, and vent to atmosphere.

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.

Iys my first time installing turbo, so im kinda nood in this. I will get ms later. Cauz closest dyno for me is 200 miles away. So here is what i got now td05 16g(rebuilded with japanese parts.), tial wastegate, begi fpr, wallbro pump, supra 305 injectors, prosport wideband, cxracing intercooler kit and cheap manifold and downpipe from ebay, msd timing, o2clamp. Im trying to get good quality parts, so is good idea or no?

Im not prep a car for racing, i uses this car for cruising and sometimes use extra hp. Sorry for my english

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?

and no bov sound? Sounds stupid bit i like that sound

My recirculated Bosch valve still made fancy noises.

if its a simple low boost setup, forget a bov for now.

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.

Save your money, buy a real computer, smile later.

so i understand tha there is only one way. Recirculate air baxk to intake. And when ill get a MS get a normal bov.?

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

Pay for car 500$ and pay for extra hp 3000$ just for fun?)

thanx techsalvager for short and resonable answer)))

Absolutely. If you want something more modern you can get an Evo 9 for $15,000 and spend $10k to make it keep up with one of our cars. You can also buy a C5z for $20,000 if that makes you feel better. Wrap up the package price, compare, then tell me how I and everyone else on this forum made the right decision. I have ~$15k in my car that I bought for $1600 (if you subtract the mistakes). Show me a $20k car that can run the times I run at one of the tracks I know like Hallett. It can't be done.

Like was said, replace the ECU with a computer which will let you run in speed/density (all of them) so you can ditch the AFM/MAF and not have to worry about what effect your BOV has on AFR. Then, run whatever BOV you like. Running an EMS will also allow you to part with your FPR, O2 clamp, and MSD box. Trade your 305s for 460+ and you'll be good to go. The jump to an EMS is worth it, every time.

That's kind of the entire point of this forum, isn't it?

kinda, i wish i can go MS but as i told already that the closest dyno is 200 miles from me. thats a main problem. cauz i cant tune it myself. and im doing this first time, so I think that my setup is good for novice, isn it??? And some experince for me. I know tha easyer to buy ready kit and read pictioral instruction, but i would love to get more experience with tune for the future=) starting from how you said "bandaid"
But Thanx everybody.

Sure, piecing a band-aid solution together is a good way to learn the ins and outs if you're not familiar with FI or cars in general (that's how I did it before my MS). But as your needs grow, so too does the need for "proper" management.

Dyno is a moot point. I (no expert, by any means) roughly tuned in my fuel and left the spark as standard on DIY's basemap until I dynoed, which was also roughly 200 miles from me. Megalogviewer made this easy. Even on that rough tune, which was just DIY's basemap with fuel tailored to my setup, the car was much more driveable than with bandaids, and after going to the dyno, fuggitaboutit.

And I can run whatever BOV I choose. :)

You might not want one at that point. Recirc isn't always silent like you think. It is on factory turbo cars for the most part, but that has more to do with the factory air box silencing everything. You will be running some kind of cone air filter and it will be noisier.

I have a begi re-circulatory BOV and crossover pipe, and a pipe with the air filter for sale Here. Shoot me a pm and we can work something out. Sound wise it is only a little quieter then my Tial VTA BOV.

Fast and Furious 5??? do you really need the annoying sound between every shift?
i'd love to go without it if I could. but then there are guys running 4 PSI and look for the loudest BOV to announce "this here car is fast sounding". good luck .....
