I'm using the apr r1 , bigred the noise sounds like the dv at 0 psi the diaphram is vibrating open and closed but not sure yet if that is normal

 

they get a stuck piston

 

i have the gfb hybrid, i love it. Only problem i have is that the spring inside is a little weak and not changable. It basically blows off loud then kinda flutters, but oh well

 

can we get a sound file thread going? lets hear your audi bov's

 

Well I am about to place an order:
Atmospheric Blow Off spacer for VAG 2.0 FSiT

Feedback on this type of bov please. Thanks

 

So what this thread states is no BOV's? but a DV instead. What would be the best one for a B5 A4 1.8T

 

what if you are using an aftermarket turbo kit? is all this talk just about putting a bov on your stock audi turbo system?

 

Try reinstalling your DV1 in the "Reversed from OE" orientation. The reversed orientation is actually the proper connection direction for the DVs used on the 1.8T and other VAG cars using a similar setup. Reverse from OE orientation means with the flow of excess boost pressure air into the DV at the bottom center port, connected to the plumbing from the compressor discharge to the intercooler crossover pipe, and the side port connected to the turbo compressor intake pipe.(TIP) The reverse from OE orientation allows for the use of the lightest spring and pre-load, while also providing for the fastest response and leak proof performance of the DV.

 

ive heard the forge DV/BOV is pretty good. and ive also heard that the stock audi TT DV is good also. true?

 

I ordered the Forge BOV/ DV the other day and recieved it today.. We replaced the factory DV with this one today but didnt get the PSSSH noise I was expecting... We thought maybe we had it on the wrong way so we tried it the other way... Still the same thing nothing changed.... Any suggestions??
