Adjusting A Sard R2D2 Bov

[stig mick]

Just bought one second hand it doesn't seem to want to open up all the way I'm still getting flutter

The thumb screw is all the way out as far as it can go

Any ideas?

Yes I'm not all that keen on vent to atmosphere bovs

But it's better than no bov at all

i had one on my series 6, make sure its not seized try oped it with your thumb and check your vacuum source for the top sees boost and vacuum.

Running no bov will cause no harm to the turbo. I don't think there has ever been a case where the usual flutter has killed a turbo... I'd feel safer with no bov as I hate the over fuelling issues with atmo. None the less, as above, check your piston. Maybe your atmo is too close to the turbo. I've got a turbo smart bov and it flutters a spilt second before the tsssh. its no longer on my car. It was way too close to the turbo.

I tried it in 2 positions and It still flutters

I opened the whole up last night it's not seized I just have a feeling the spring is to hard
