Just curious if any body had put an underdrive pulley on there car, and how much of a difference it made, or how much HP you gained,, thanks.

Kwanza always bashes on the 5sfe motor, especially in NA trim. I have wanted an underdrive pulley, but I'm worried about the rpms needed to run accessories. Everyone knows the 5s is a happy at lower rpms. That is the rod/stroke thing Kwanza was talking about. You would regularly have to run the motor faster to make accessories work propperly. I have a light weight flywheel, and it picked up a little, but not much. Every little bit helps though. If anyone has an underdrive pulley for the 5s that they are willing to sell because they didn't like it, I'll buy it, as long as the price is right.

The crank is what is balanced. The pulley is semetrical, I don't see how it's used to balance. -------------------- Live Free, Be Happy
