Flutter/Chatter after DV Cold Side Relocation for 'LC' **HELP**

[Mo Arif]

the noise before was perfect, proper recirculating DV noise.

reading through some UK mkivs threads, it seems like it could be the DV itself?!! it's not even 1 months old yet!?! I bought it brand new?!!!

It's not cause of the 90degree bend youve got going into the DV causing a restriction to the charged air escaping through the DV, leaving some pressure going back through the turbo is it?

Mo what does boost gadge read on idle? Mine did this exactly the same when I left vac pipe off the top of DV sounds nice lol check for vac leaks mate could be the cause

 

[Mo Arif]

ok UPDATE:

Removed the relocation and put it back to normal, sound gone?!!!!!!!!!!!!!!!!!!!!!!

what a waste of time

Right, ive just seen this thread, on my LCR, 007p in standard place sounded normal, no flutter, i did the DV relocation and sometimes when i build up boost from low revs and let off, i get a slight flutter

sounded to me like your dumpvalve was finding it hard to hold presure, dumpvalve may need a service. or the vacuum pipe on top of the dumpvalve is to long. 3mm vacuum hose might have been better.

That's normal I think coz you not really lifting the piston so in affect it's not opening properly nothing to worry about

Got the rite spring? As you have so much more piping it migh find it hard to push a stronger spring up???? Just a thought
