I think the diferences are that one is an underdrive and the other is just light weight.

To gain a better understanding here, the difference between the underdrive and the lightweight is that the underdrive is smaller in diam. than the original right? The lightweight is just a different type of lighter metal.

The Indigo pulleys are lighter and smaller in diameter. I have a set here on my desk.

They offer less drag by spinning the items slower, thus less drag/loss.

Personally, if you want to do this think this through.

Lets say you swap out the crank pulley.

It's (1 Lb Less)
It's an Inch Larger so everything spins a bit slower.
Not much Of A Gain..for your big BUX

Or Do it My Way.

Remove the A/C (70 Lbs)
Remove the P/S (50 Lbs)
No More Loss Due to 2 Complete Items.

All I have hooked to the Pulley is the Alternator and Water Pump
That makes the type of diference that becomes noticable.

Haha, Brian you're nuts. If I did not live in GA, removing AC might be an option. How's it feel with no power steering?

Get the manual rack off of a Base model, install it and it's fine..

Actually the stock crank pulley is 5lbs and the RR-Racing pulley is 1.5lbs.

The stock muight have been 7lbs, I can't remember right now, but it's in an old thread. And it did make a noticable difference.

Probably not as much as taking off 150 Lbs.. :)
