Anyone happen to know the specs on the stock hydro-fan pump, as in Gpm and Psi output? I'm looking at the feasibility of using the stock pump to power a hydraulic motor for a centrifugal supercharger, and I would assume that the pump is pretty strong considering how heavy and fast the stock fan is, and the fact its Lexus and "good enough" is not in the engineers repertoire. I can speculate all day, but without even rough numbers it's just a waste of time. A good waste of time though, seeing as this is keeping me busy at work.

 

Bumpity bump, anyone have any ideas? If they're are any engineers in here, do you happen to have any advice on how to test and calculate pump flow?
