Ok so im sure anyone that hears a car go by with a turbo, you love the sound of the flutter "tu tu tu tu tu". Although those with any knowledge in the forced induction field are aware of a thing called compressor surge or "cavitation".
For those who do not know what compressor surge is:
Compressor Surge- A condition caused by compressed intake air caught between the compressor wheel and closed throttle plates. When you get off the throttle after a burst of acceleration, the plates close but the compressor wheel may still be sending compressed air into the system. If the compressed intake charge cannot flow through the throttle plates, it will flow back to the compressor, causing it to spin "backwards", which could result in bearing damage.
Some of us know that certain Blow Off Valves can imitate this imfamous sound, one known example ise the Differential Bypass Valve or DV for short, which usually come on VW 1.8T.
An example:
The question that i want to know, and many other turbo enthusiasts may want to know is,
Is it possible to modify a standard BOV to produce the infamous "flutter", without causing severe damage, if any to the turbo without using a DV?
Thanks!
