My "forge copy" bov does not flow properly, i can still hear the turbo stalls a little bit even with low boost.

Does anyone have any suggestions to a better flowing one? Preferably a recirculating one. Unfortunately i only have a 25mm outlet in my boost hose.

I know everyone has them buy I think as an allrounder the Bailey one is spot on

Yes i can hear chatter from the turbo, is that not the same as the turbo stalling a little bit?

mine has a bailey and chatters aswel as the dump valve but should be getting the spec r recirc soon, ment to be realy good

The raeson behind this is becuase the boost pressure has to overcome the tension on the secondary piston spring, or the main spring is slightly too strong, fitting a single piston dumpvalve or one with an adjustable main spring rate will cure this, but i dont think its a flow rate problem if you hear it light throttle/ low boost.

Yes mate, works well on anything flowing a lot of air, its massive and the build quality pretty amazing to be fair. Best dump valve I have ever seen!
