Chatter is compressor stall or surge, not the wastegate fluttering about. as you shut the throttle the turbo is still spinning and the air has nowhere to go. Not good for a turbo. Its loads worse if its heard on boost though

Carlo am i correct in thinking you've got Euans old engine now? Did it/does it have a D/V in its current guise?

For me personally, id get a re-circ and since you will no doubt go for a GT28/GT30 (according to Stoo) i'd see no harm in it.

Im not running one justnow but will hopefully be running 2 bar + soon so going to look into getting a hose to refit the Bailey valve i use to run.

So is the opinion that if your running a gt30 or larger garret turbo and lots of boost you need a dump valve? Does anybody not run one, and has anybody had a turbo failure?

I have a bailey recirc if anyone wants one

dump valves ? i no likey !! but a coz had them from a kickoff so shouldn't cause any running problems which would be my main concern.i am only running 20psi and to be honest you don't really hear the d/valve.just LOADS of chatter.tried a bailey item,its not for me.mine made a right weird noise like unplugging your air hose off a compressor,so back to the collins one with a new diaphragm.it just sounds like there is a turkey under the bonnet but so far i haven't found it,just the one in the drivers seat !!
