I can't see it causing any issues. I can't see it doing anything beneficial either, except maybe making the pump last longer by reducing the wear and tear. Whatcha trying to do?

I am not sure if it matters or not but your brake booster is hooked into the power steering pump as well.

Yup. The hydraulic brake booster gets its pressure from the power steering pump. That means when the pump goes out you have increased resistance in both your steering and braking circuits requiring a considerable increase in effort to operate either system. Was there not a recall recently in these systems for the '04-'05 trucks?

Is that your pulley Ryan? That thing is a work of art. I've always wanted to fab up some pullies that matched my rims.

You won't feel 10%, meaning the effort to turn the wheel or meaning power increase? I think that's true for both situations. I've pulled my PS belt on my car at the track before, and it did absalutely nothing. It just made the turn off really hard. On the circle track car we used to run a gaint pulley on the water pump and PS though, so it did make a difference there, but we never did back to back tests.
