weird one forge dumper

[turbotony21]

wen i got my s70 t5 it had the standard dumper still fitted plus a forge dumper aswell so i got a blankin plate off fleebay to remove the standard one and just keep the forge on wen i bought the car on my trip home i couldnt here the forge at all and its still the same with the standard removed still really quite but yet if i rev it it blows off louder than wen im driving like nite and day im puzzled like only been out incar couple times just to wee trip to garage get work done and never booted it really as was in town

Most likely the spring in the dv is too weak and letting pressure past while on boost

ok thanks

Could it be that the spring is too hard, needing a strong vacuum to let it open?

i've just bought one, looks like i've got some reading up to do to see which spring i need to use

[T5frankie]

you'll need a softer forge spring

i got that kit included, just didn't know the colour/psi rating. I'm only starting on the 15g so might try a shim'd green to start with

I'm running the red spring on 25ish psi and is fine, more chatter less air loss
