Pulley question...

Idk if this is a dumb question but what is the difference between the lightweight STANDARD and UNDER DRIVE pulleys by stillen?

The lightweight standard pulley is the same size as the stock pulley but lighter. The underdrive pulley is both lighter and smaller and reduces power to accessories by 20%.

Exactly..

Underdrive pulleys are good unless you're planning to supercharge, then stick with the standard size (or you'd be spinning the blower slower), or if you have some monster sound system, and needed every possible amp out of the alternator, although we haven't seen anyone have any issues with upgraded audio.
