it is comming from the TB and I believe it is in line with the VSV (Vacuum Switching Valve). Adjusting the spring preload gets it to the piont where it stays mostly closed but it starts fluttering a bit. Any tighter and it won't open at all. Under load it closes and opens almost all the way on the atmospheric side.

My intention is to find another vac line.

The stock boost on the tC is rated at 7lbs which realistically means +/-6.5lbs ... could this explain anything since the low spec of the Splitter is at 7lbs?

 

No... that just happens to be the lowest boost that you can run on a VW 1.8t.

Too little boost won't open the valve, it has to be either too much boost at idle present in the charge pipe or too much vacuum on the top of the valve.

 

A restrictor in the vac line might work...

 

i would think that anyone running a higher boost pully would be able to adjust this thing easier then...

 

anymore information on this? I just got mine and i dont know if i should install it or not. I read the first page writeup and i orderd it, now i just saw the other pages.

 

i thought it was possible to fully recirculate with this.. or do you need a seperate "kit" to use this feature?

 

Comes with a plug to run the BPV as either as a hybrid, a full recirculating BPV, or a fully atmospheric one (not recommended on our vehicles).

 

hey bluemeanie when your having trouble at idle, is it only when you have it set up as a hybrid? or does it also leak when set to full recirc?

 

watching..

 

watching

 

bump

 

I havent got around to installing mine yet, But when i do ill make a post to let you guys know how i make out.

 

thank you

 

Full recirc seems to be fine, hybrid is still fluttering a bit at idle but it doesn't happen all the time.

 

so let me ask you blue, are you still satisfied with your bpv, or are you gonna sell it and move on to a regular full recirculating bpv

 

I think the fluttering is from the evac senor thingy the green part on the vac line it makes my boost gauge bounce at idle.

 

do you know what setting your at with the clicks and stuff?

 

so does nobody else have this thing, or are you just to chicken to experiment and find out what works for you

 

if i could i would.
found it here for 148.75

the interesting design also allows for differnt trumpets to be screwed in for different types of sounds.

 

well I guess ill have to snag one and see what results I get
