^^ +1... silky & sweet sounding!!! like the JDM big boy Supra's

 

C to boost only,

A + B to vaccum from intake mani.

I had just A (I think) and I hade major flutter everytime, however I noticed one of the ports was loose so maybe that was causing the flutter and not the setup. I will actually go disconnect one take it for a drive, then swap it on the street and drive again.

But my BOV definitely does not sound almost anything like my stock BOV. It barely sounds like a swoosh at all, it sounds like a crack almost, but not quite as sharp as a crack. Maybe as like a nutcracker breaking a nut. Its quite hard to describe, but definitely not just a SWOOSH of air.

 

Just went out to test and looks like just having C to boost and B to intake mani and A vented has worked best for me but I still get flutter basically whenever I am not boosting heavy. For the first time though I got a much more normal sound more like a swoosh but only when I was like over 12PSI. I guess I didnt realize but I think I was actually getting some flutter on almost every shift before.

Can a leak in the connection to my intake from my BOV cause flutter? I have a wierd custom setup with a steel 90deg elbow and maybe that setup is leaking and causing problems?

Feedback would be GREATLY appreciated.

 

With this new change, is there anything different about the BOV aside from C being blocked? Cause if its the same shouldnt we just block ours off?

 

The enitire C-port chamber is modified in the newer version...

 

Ah I see, thats lame cause I only got mine about 3-4 weeks ago

 

i bought mine this week and mine doesn't have the blocked off c port what a rip.

 

contact (Synapse) Pete and let him know, I'm sure he will work something out with you (guys), dude is cool and willing to help! I wouldnt recommend drilling the chamber out until you actually seen how it's done. Like I said earlier in this thread, they did mine in a matter of minutes so it can't be that hard and get them back out to their customers!

 

With anybody with the older normal Synapse have any success with port C besides to the wastegate?

I am getting flutter with C to wastegate and all 3 sets up of Just port A just port B and both port A and B. I guess next is to try and do Port A with B blocked and port B with A blocked. How would you go about blocking the port? Buying a rubber piece to go onto it?

If I cant figure this out soon I will probably just sell it and buy a Forge RS.

 

is anyone running a bigger than stock or stock appearing turbo having problems with the bov? I'm not currently experiencing any of these problems w/the HTA 3582r turbo kit that I have and just wondering...I have the older version as well

 

I'm running port C VTA cause I have the Buschur LICP and it doesn't have the nipple like the stock LICP does. I get terrible shutter in part throttle, but I also have A & B ported to vacuum cause thats what synapse said to do back in the day. Any idea where else I could T the boost only source from? I'm gonna test out just using A & B separately tonight and see how that goes. Cheers

 

Nate I am not sure what you mean about the LICP nipple? Why can't you get your boost only source from the wastegate?

 

I will try that thanks

 

There's a mid-section pipe (black) that comes off the turbo and connects to the LICP...

 

With the Buschur LICP (Which I also just installed this week), the LICP takes the place of the "j-pipe" and it doesn't have a nipple like the factory j-pipe does. I just had a local shop drill/thread in a nipple for my LICP.

I also tried running just A and/or B just to see, and the car did not run well at all. It wanted to die at every stoplight.
