Is the block-the-dump-valve-hole-off-for-a-flutter-noise-mod any better for the engine then?
Not really a case of being better but a DV is not required on these cars unless you fit a turbo of T4 size or bigger (not too likely on a CVH) or you are running more than 30psi of boost (again not too likely). All you gain from the fitment of the DV is the gay noise. There are arguements that the fitment of the DV can causepotentialy harmfull overspeeding of the turbo.
RST's do not require one so why bother fiting something that will do nothing to aid performance or turbo longevity?
Because some people like the noise! People like what they like!
I do agree though, if it's doing harm, it shouldn't be there. I will have a look into having it removed.
Didn't think the chatter noise on mfi was particularly loud though?
