Forge DV 007 spring rate

[Noam]

Anyone know what would be the ideal spring on runnig 18 PSI of boost on a k03??

Red or Blue?
Thanks in advance.

green. - neither of yours suggestions... they are too stiff.

yellow at most

im on blue as ive not changed back to yellow/green, whats the difference? i thought it was onyl a problem if your running higher boost and a weak spring,, not the other way round.

Not sure if this is peak / sustained or what but this is what forge recommend.

Green - 5-15 PSI

Yellow - 15-23 PSI

Blue - 23-30 PSI

Red - 30 + PSI

Black - 100 + PSI


OK I made the last one up....

 

[flashbsd]

coolio, but does it matter im runnign stiffer on lower boost?

 

[acidstrato]

the boost forces the dv open..too stiff and it wont open..too weak and it opens early...decide for yourself i guess

 

[ibizacupra]

too stiff a spring like blue and the DV wont open properly...
you need a DV which has enough spring pressure to seal, but is as easy to open (fast) as possible.

I have tested a gree spring for leak to 22psi when I heard the faintest of hisssss, like you would never feel in real driving terms.

So with a REVO or Jabba generic remap is it right that you should change to a Yellow spring?

 

[cordobabrendy]

not necessarily, ive been running a yellow spring for a year and a half remapped and non remapped, makes bugger all difference to a green really so not worth the effort to change.

 

[acidstrato]

have always used what ever spring came with the dv..green i think? never any problems

I've run both the Yellow and Green on my REVO Audi A3 1.8T (150bhp Stock so comparable to a Beeza). Couldn't tell the differance between them on the road but had the Green one in for my RR run and it made 192bhp/218lb_ft and didn't appear to be bleeding boost in the slightest. So no need for the yellow one IMO.

me too

although after reading post 4 i might change mine to be safe to the yellow spring

If bill can run 480bhp on a green spring I think most other forum users will be OK with yellow, I only used yellow in my LCR (270bhp) and that was fine too.

 

[CupraTgirl]

Yeah its just something i was told that may need to be changed

Thank you all
