Nice review, I just bought a G1 supercharged M3 and have had it for a week. Drove an older ESS supercharged M3 the week prior so it's an interesting comparison.

I definitely think above 2500rpm there is constant supercharger wine/hum. Top of the rev range sounds like a turbo flutter which is cool.

The car came with the 91 pulley but will be switching to the 93 pulley for next year cause we have that at the pump.

My car also did not come with the cold start delete, so cold starts are loud. I just bought a turner valved exhaust that I'm going to put on to help.

The supercharger definitely seems pretty chatty at idle when your on the outside of the car. Haven't heard the old ESS supercharger at idle to compare though.
