yeh I know there is a few different variations in sound just by adjusting spring pressure ect... but this is so unique that Im sure the BOV plays a major part in the way it sounds....
its like a quick whistle, instant and dosnt flutter unless released slowly... but it still keeps the high pitch whistle sound..
I wish I could describe it better or add a sound clip....
but anyone who has seen this BMI episode should know exaxlty what Im talking about....
just hoping someone has the same BOV or knows someone with one that makes the same sound...
