issues
there is a great debate, at least with sti's, that crank pulleys are harmonic balancers. Placing a non harmonic balanced pulley could and will slowly vibrate and destroy your engine. Unfortunately most have not been running pulleys for more than 100k so no one really knows. Underdriven is best for power, but seems to mess things up. OEM sized pulleys are just lighter weight.

torque loss
again, i do not know too much about audi's yet.. but on sti's a lightened OEM size pulley makes the car rev faster, thus better for luanches and downshifting/revmatching. Please say it runs through the gears easier and also saying torque has INCREASED.
Reason for no light fly and no light pulley is that too much mass reduced makes launching hard. as is, drag cars do not have a lightened fly, you bog too easily.
