Blow Off Valve

Dumb question BUT- Can you put a blow off valve on a supercharged engine. Like something such as... Hmmm.. I dont know, Maybe a MINI COOPER S!?
Just curious, i mean boost is boost whether or not it is coming from a turbo charger or a supercharger......

LOL!

To the OP - no, you can't have a blowoff valve, but you can put in a fake one.
A BOV is not needed in a supercharged engine. The SC has a fixed displacement, unlike the turbo which will 'overboost'. You could vent to atmosphere, which might sound cool (to some) but you would then be losing boost.
