Hi guys, just wondering what would be signs of my bov (stock) not staying shut? Sometimes when im giving my T some s**t, its like its not using all the boost its producing and when I change gears it lets off a louder than usual flutter or whoosh. Its been tuned and is producing around 340 rwhp at 8 psi, could that xtra bit of boost be to much for the stock bov to stay shut? I do regular maintenance to keep my boost solinoid from sticking so im pretty sure thats not the problem?
Any ideas?
Thanks,
Shaun.

sorry but stock turbo'd engines have bov's? thought it was just the wastegate?

I dont think the xr6t has a 'blow off valve' as such but it does have a plumbed back pressure relief valve fitted stock which is kinda the same type of thing so i find it easier to just call it a bov, and yes it does have an internal wastegate that is controlled by the electric boost solinoid

The XR6 Turbo does indeed have a BOV. I have not heard of any faulty ones though. But may be an idea to upgrade the stock one if your boosting higher.
