Comes with it. It's removable though.

 

If you order the bov with the adaptor plate for the hks, per Prestige is does not comes with the c-ring and o-ring. Can be a problem for some if you want to sell the hks.

Until then, you can buy the c ring/ o ring from http://shop.edoperformance.com

 

That is correct. The synapse BOV does not come with a C ring. You will need to keep the existing C ring from your HKS BOV. We do carry HKS C-rings, however they have not been added to the website yet.

 

yeah...i noticed there was not an option to order it with the HKS adapter AND the anti-lag...

 

alright, I just got my Synapse bov im gonna swapp it off with my greddy rs bov. my car was experiencing prblem just like brown dogg.

 

install it today but my car keep on stalling an shutoff . I dont know what happen, so i put my greddy rs bov back on and recirculate it an runs fine. someone know hoe to work this?

 

If your synapse BOV is venting to the atmosphere, you need the anti-stall kit. If you're recirculating, you might want to check what ports you're using on the BOV.

 

I am using ports A and B, I guess I need a anti stall kit , I tried looking at your website but you can not purchase it individually. One other thing does it need to be tap as close as possible to intake manifold vac line, becuase my wastegate actuator is tap already to vac line.

 

We're going to add the Anti-Stall kit as a separate option today.

in your case, since the Greddy RS was recirculating, your car would run much better recirculating the BOV. The only reason we didnt' recirc browndogg's tC was because the dezod kit isn't made to do so.

 

wow...your greddy RS was already being recirced and it was having those issues?

 

got mine on, havent hooked up the third barb yet, gotta find a fitting for the compressor. still flutter dumps but not as much as the hks. sounds like puff, puff, whooooosh. it's quieter too. i wont be able to do a before dyno just an after, which will be soon.

 

Hook up the port 3 to the wastegate line and that fluttler will go away. It make the BOV open insanley fast.

 

i plan on it once i get the fitting.

 

So on my car... port 3 inst being used right now. And I have the Tial wastegate and one of the ports on it is just open to the atmosphere. So if I hook up the empty port on my bov and the empty port on my wastegate.... that will work?

Do you have a pic of your car and bov and wastegate doing this for reference? That would be awesome!

 

No. The line running to the bottom of your wastegate should be the boost signal line from the compressor of the turbo. "T" that and run that same sidnal to the port 3 and the BOV will work sooooo much better.

 

Installed mine on my turbonetics kit last night. Seems to work great, no more stalling and most important, no more backfires! Those huge backfires were going to get me pulled over eventually. I would say it's a great improvement for a small investment.

 

Is that safe to do?

 

port 1 and 2 are on the back of the unit and 3 is on the side. it is designed to have the boost on that side port.

 

Its how its made to work. If you check out there youtube videos mine sounds just like the wrx test car.

 

I was wondering if you tried hooking up the second unused port on your old Raptor to the boost line near the compressor. IF you tried that back when you had your old Tnetics setup did it help with compressor surge?
