RE: Underdrive pulleys + blower.....
The other bad part about using a U/D pulley on the crank for a FI car is that even if you DO get a smaller pulley for the blower, you will be loosing surface area on the blower pulley, so it will be more prone to slip.
Aka, even if you repully the blower to keep the output the same it will tend to slip more. If your running signficant amounts of boost this can lead to a loss in PSI and belt shredding.

Are you sure he has underdrive pulleys and not a s/c upper pulley? With s/c'd cars, the smaller the s/c upper pulley is the more boost they create... may want to double check with him, see which pulley he has.
