turbo shudder problem

just started today my new BOV gradually stopped working..now all the backpressure is being slammed against the turbo making that horrible shudder flutter sound...i tried putting my stock one back on and also another BOV i had...still does it..car is reaching peak boost but not releiving the pressure...any help would be great

Sounds like your 'passion' for modding your Subaru has created a terminal problem.

Have you checked the blades on the impeller in the compressor for damage?

everything on the turbo is fine...i jsut drove the car again after a couiple of hours and it was back to normal...my passion for modding comes with problems yes but they are all worth it...anything aftermarket has its quirks....but what fun is having a stock car anyway

I don't blame you for modding the car, temptation is a hard thing to resist.
If the car is back to normal, it may have just been a 'bedding in' thing with the replaced part, which happens with mechanical things.

Glad it's sorted itself out though.

make sure you didnt kink or twist the rubber hose from the intake manifold to the bov.
