I added the clutched power steering pump ranger to the wiki mod page years ago.

I found some more info on Saginaw pumps.
All belt driven power steering pumps do the same thing so this largely applies to them too.

According to hot rod magazine the early P1 Saginaw type pump moves up to 20GPM at 5,000RPM.
The saginaw type 2 makes 15GPM at that speed.

I would really like to just take my grossly over kill Saginaw pump and just clutch it.
