Underdrive Pulley

I know this subject has been talked about briefly in the past. I've tried doing some searching through the dusty old archives to no avail. Nothing specific about anything anywhere other than one guy looking into having something custom made from the stock parts.

I guess my question is, why the hell do the N54 and M3 guys get these and we don't? I would venture to guess our crank pulley is massively heavy and we could gain some pretty sizable numbers at the wheels.

Gavin, care to jump in on this?
