Ok I have had a stock BPV, Forge BPV, and a HKS BOV installed. I am a fan of the HKS BOV. When I got the BOV installed we removed the solenoid that routes all the vacuum lines around and the vacuum tank as well as blocked off the nipple on the cold side charge piping. So after all that and BOV installed I had turbo surge. So I then I went out and bought the forge BPV. Personally I don't like it, way to quiet, even the stock was louder. But I want the BOV back on so...

First I called Vince at trifecta and he told me to try installing the vacuum tank and all other parts back on and try the BOV again, he said it might work. (haven't got to doing that yet) but any other suggestions on how to run a BOV without surge.

Tell me your setups cause I know several of you run HKS SSQV 3's

 

Subd

 

forge bpv sounds great if you ask me. and way louder than stock. and its stress free unlike a bov haha

 

i have the tredstone block off plate, tial bov with the vac line straight to the intake manifold, i just left the solenoid alone, runs the same as she always did

 

Ok obviously my forge isint installed right or something. Cause at full boost and letting off there is no sound. Then at low boost just a quiet psssshh.

 

did you line up the bpv with that slot like area in compressor housing? that could be part of your problem with it not sounding right. Personally if your on the stock turbo there is NO reason for a BOV. the bpv does just fine and bov are just really put on cuz there "Cool" and sounds "Sweet". Not worth it to me. To each there own i guess.

 

Not sure. I'll pull it out and check that

 

Pics of your hookup!!!

I bet that it is routed wrong. I have Forge BPV and its hella louder than stock.

 

I had the same issue with my HKS SQVIII bov, after doing the following I get zero surge and no audible flutter. Vince at Trifecta saw compressor surge with the stock set up and after doing this and data logging there was no surge.

Also I have the stock bpv blocked off with a treadstone plate.
