Introducing New SFI-Approved Underdrive Crank Pulleys!
We are proud to introduce a new underdrive balancer pulley for the LS1 f-body. We offer them in a 10% and 25% underdriven pulley, and it features deep grooves to keep the belts from slipping off. You can see some pictures below.
.
For an introductory special, we will be offering them for $199 + shipping, and the new crank bolt will be included! This offer will be good for the first 20 25% underdrive pulleys and 10 10% underdrive pulleys. Give us a call if you have any questions or would like to get one on order.
Thanks!

25% is the same as ASP's pulley. If its the pic I'm thinking of, then its the same pulley just shrunk to fit the price in under it (I made fun of Jason for that too). It comes with a crank bolt, and from what I overheard today the belts would run $35.
I havn't opened a 10% box yet, but I'd say it'll gain about 4-5 rwhp on 10% and the same as an ASP for the 25%. I'll prob install one myself late tomorrow night or Friday on a local car.

Underdriven Pulleys
How much do these pulleys systems help in rwhp? My car is running 13.031 and 108MPH with standard A4 converter - I want some extra hp to go sub13.00
