Aftermarket purge valves?
I'm wondering if anyone makes aftermarket purge valves for the C32? I'm mostly looking for a good blowoff sound (like that found on most aftermarket blow off valves on cars w/ turbos). If no one makes these, does anyone know exactly what part of the valve is the silencer?

Both cars came stock with Bosch and it was a direct replacement. I don't know
your cars setup so can't directly answer your question just turbo cars. Also HKS
makes a nice unit.

Forgive my ignorance, but I was unaware that a supercharger could utilize a blow off valve since it is belt driven and under very little load when the clutch disengages.
My understanding of the use of such a blow off valve for a turbo car is that catastrophically damaging amounts of pressurized air need to escape from the turbo before/during shifting (depending on how you look at it) because it is statically connected to the exhaust and engine intake. On the other hand, the AMG kompressor is connected dynamically, releasing it's connection to the engine intake when not in use or when use ceases.
Anybody have any thoughts that knows more about this stuff?

You are reffering to a blow-off or bypass valve. This valve is used on turbo and supercharged cars to either blow-off or bypass boost under throttle lift-off.
However, C32 does not use one.

is there a point to this, because as the car revs down, so does the supercharger, so there are not the same problems as with turbos, because they stay spooled up, plus one more thing to break on a very complicated motor

On the c32 when you remember the engine cover that reveals the blower pully, on both sides and connected to the blower are two valves that look like BOV's. What exactly are they then? Also, I thought that even superchargers had to release pressure for gear changes so it doesn't overbear the torque converter? What happens to the pressure that is created when accelerating, and you simply let off the pedal?
