They are different.

Wastegate & Blow Off Valve

[rion]

yeah, but it seems they do a same Job, which is releasing excess pressure...?

edit: bov is connected in the main pipes pala...

looks like they do same Job but wastegate works on open throttle releasing excess pressure. while Bov works on closed throttle releasing excess air pressure to avoid bouncing back to the turbo.

wastegate=Engine protection
Bov=Turbo Protection.
=same Job of releasing excess air pressure.

verdict= useful rice. (very cool sound fx. specialy with trumpets type)
