im not all that familiar with supercharged cars, as well with minis, but with a turbo charger i know one of the parts u can up grade is a blow off valve, do they make them for minis or am i just an idiot?

 

The MINI doesn't have a blow-off valve. It does have a compressor bypass valve but that works to allow air to bypass the supercharger at lower RPMs and light load conditions for improved fuel economy and throttle response. It is a part that can be upgraded on the MINI but it's not designed to vent boosted air out as much as to allow air to not have to go throught the compressor when there's no need for boost. It won't make the pshht noise most BOV's do.

 

aww that kind of bums me out...but thanks for the info...ya all i really wanted it for was the sound any ways..
