Just something to remember. If you change the balancer hug ( if you adding a blower you will want a key'd hub and billet) and pulley you will need to make sure that the SC pulley remains in alignment with the blower so you don't end up loosing or tearing up belts. Some of the after market stuff is designed only to work as a stock pulley would, and can have extra material to meet te SFI rating so it could will result in the SC pulley being futher forward.

I bought my hub from Thunder racing, bt I'm sure others mae then as well. You want to also make sure the hub seats properly on the crank and may need to bevel the lip so to not score/dig into the crank where it starts to flair before the front bearing, if it does it can result in crank failure, snapping the snout off. This was a problem found some years ago with the Eagle crank design and and the billet hubs.

Due to my ET, I need a SFI pulley and was looking at the JEG's unit, but found no one running one, everyone that I know is running the ATI. I Plan to try the Jegs unit over the winter.

Underdrive pullies can affect the charging system and hapens often with L1s, you would need to change the alt. pulley to compensate. Power steering and AC isn't effected as much.
