Well I forget what the rotaing mass to hp savings is which i am sure someone will chime in

These weights are from a 95 stock to 95 alum.

Alum Stock
Spinning wheels Sc pulley 9.4oz 1lb .05oz
5% OD Jackshaft 1lb 14.6oz 3lb 2.2oz
10%OD Crank 3lb 10.2oz 6lb 7.1oz
 
I would like to see the differance in all pulleys. Not just overdirves. PS, WP, Crank, WP & JS pulley. Some of us cant run the 5-20% overdrive. Its good info though.
 
The alum water pump PS and alt will be in a couple weeks. Although I will not be able to state the weight of water pump because I have electric ;)
I can tell you if you go the stock crank it would be even more wieght savings from what i stated since the overdrive has a bigger radius thus more material
 
An extra bonus is the aluminum pulleys look a hell of a lot better than the stock steel ones, especially after they're polished.
 
Oh i definately agree I love mine and I dont even have them on the car right now. It was more of a question that other people might have. I love my alum.
I have rear Mark viii arms, mark viii diff, custom driveshaft alum flywheel and above stated pullies anything to make that fatty lose some much needed lbs
