Good tip. Thanks! I quite like the noise, but we'll see it attracts too much police attention.
As for the valve, I'm running a Turbosmart Kompact 25mm Bypass Valve.
I tried a dual port Kompact 25mm to get a bit of "pssssshhhhhttt", but regardless of how the spring was adjusted, throttle response sufered, and it was venting whenever engine braking (which makes sense with a SC setup as boost is relative to RPM directly rather than engine load.
