I have just bought a forge atmo dump valve and when it dumps it just give of a short quick pssssh and i was comparing it to my mates baileys dump valve and his give of a long pssssssssssh sound.I am just wondering is the right for my make of dump valve?? Cheers Gary

 

Gary,

I had one for a MY01 and it would give a longish noise on every gear change and let off of throttle, only problem it would not hold boost. So I had to have two ally spacers fitted to it and then it only made a noise when changing gear from full boost. It is now in a box in my garage. IMO they are a waste of time.

Si.

 

I want one but to quite my standard recirc one down my blitz cone filter makes it sound insane

 

When i bought this i never got a gasket with it so i used the original one. Was i supposed to get one? It does not sound right at all. I think you are right a waste of time..
