I myself had two power steering lines rust straight through one day while I was driving down my street after having spent a month assembling my fuel system. After losing power steering while driving I can definitely say that any hp gain would not be worth the loss of control. Plus, it took me, my dad and my 90 psi air hammer 2 days to knock those rusted out pipes off the car and replace them, so I don't really feel like entertaining the notion that I could have avoided all that labor.
