Which DV Spring?
SIlly question, i no they have a guideline on the site!
Iv got a Forge DV and an MRC remap. Its at about 0.8bar ish.
Now do i stick to the standard spring (Weakest) OR move up to the next one.
I can hear the car dump each time i let off. And it seems to hold boost.
Would putting a harder spring in give it a little more peak boost?
Thanks all, and again sorry for the silly question!!
Re: Which DV Spring?
Had this dilemma with my mapped S3. Had the yellow spring in it (which is one up from weakest) , but it wasn't until I was looking for a boost leak that I tried the standard valve back on. Immediateley a marked difference. It seems I was leaking boost through the DV. Got the red spring in there now ( heaviest ) . You can just hear the turbo starting to stall on small throttle inputs. A little more boost to dump, and you can hear the valve dumping. If it were stalling the turbo on medium to higher boost I would swap it for the blue, but it seems to dump meaningful boost ok. This is at 1.5 bar though.
So trial and error I would say.
