[s-cars] Forge BPV's ??(diverter valves)

[joeamund]

Hello listers!
Does any of you have any experience with the Forge BPV's?

( http://www.forgemotorsport.com/s4.asp?cat=audis4&catalog=AUDIS4DV )

I am a bit puzzled over the two types diverter valves, one is the FMCL007P
closed loop all aluminium with a piston and the other is a FMDVR-Race also
aluminium but with a diaphragm and four different springs.

I would  think the piston  type would be more durable, since I am having a lot
of trouble keeping the Audi RS2 BPV to hold in my car at all. the diaphragm is
ripped almost apart after som months of driving and they are expencive too,
let alone the power loss.(which is the worst...)

I probably should have gone to a bigger dimention when I did the plumbing on
the IC, but is currently running two identical RS2 BPV, and wanted to hear
your opinion before i purchase two new ones.
