I never used any form of dump valve on the saxo at 9.5psi and never had an issue with it. As ross said though, it really doesn't matter at mild boost.

My s14a had a re-circ when i bought it and running 22psi you don't hear anything on shut off. I removed the re-circ didn't have any issues apart from it would let a few flames and bangs out when you lift off but this was due to it being afm so it chucked extra fuel in expecting air to be going in with it as it normally would with a re-circ.

There is a lot of debates about it damaging the turbo or not, personally I never use a dump valve of any description as I enjoy listening to the chatter. A good friend of mine works at a well reputed engine tuner and he is dead against it and therefore always runs a re-circ on his gtr. On the flip side though, a guy who's in the same circle of mates has a sierra cosworth running 30psi on a gt30 and he runs no dump valve, so far no problems.
