who runs the standard bosche dumper?

i recently put one back on the car and its ok, not much difference but theres still a slight noise which aint ott and u can still here a bit of the wastegate chirpin

comments welcome

 

If you mean the standard cossie dump valve I think the purpose was to not give a ptschh and to not give off chatter, but to eleminate chatter and just hear the revs of the engine

 

yeah i see wat they meant to do, it does the job, but it still goes pshh pretty quietly against uprated aftermarket item


if i give the car full chat it sounds good

 

Take the fooker off completely

 

if it makes a noise the diaphram is probably knackered

 

hmm how can i resolve this?

 

dont no weather or not u can get new ones or not, but u can get aftermarket recirculating dump valve which are basicly the same just shiny lol
