Depending on turbo really. Newer VF's are stronger, TD's are good and strong.
Pros, sounds good.
Cons, turbines are forced the other way and stall. Turbo life is shortened. And as it stalls slightly, might take a little bit longer to pick up again.
Up to you really.

im not sure about this but i read on he web that it is a misconception that it spins the blades backwards as there is too much anertia in the blades but it does slow them down and cause that flutter sounds as the air goes back in this is not a forced oppinion im just sharing what i have read and would be happy if someone could verify or give reason to another theory thanks
on another note my97 catalunya does the flutter noise but i have some sort of dump valve sitting just under my intercooler on the righ hand side any ideas? maybe needs wd40'd or slackened maybe?????

I have a TD05 18G and as prev mentioned, the TD series are strong turbos which can put up with the compression coming back thru the blades. I've also heard that with the earlier VF series turbos its not adviseable to remove the dump valve.
The noise you get without the dump valve is amazing - I love it!!!
