Stock Bov Max Boost Holding?

[fredzz32]

can the stock bov hold upto 1 bar?

also ive searched but theres so much crap what is the little hole next

to the piston for? smoother boosting or to prevent overboosting (spiking)?

help would be greatly appreciated trying to decide whethet to piss the blitz one

off and just put the stocker back on.

also if i put it back on do i put it on as is or block the small hole as stated in some modification threads,

whats your opinions?

Yes, 1bar is a walk in the park.

you can also "crush" your stock BOV. just use a c clamp and crush from top to bottom about 3-5mm. this increases spring pressure which allows it to hold more boost.
