I've seen small displacement ones amounting to about 13 HP sustained
capacity for a couple hundred. That's enough for highway speeds, barely,
with good aerodynamics.
Would like to find something capable of 40 GPM at around 2000 PSI, 3K RPM
for pump, 1500 RPM for motor, very roughly, to be in the same ballpark as a
mid-performance car.

what is a good price for one of those and what prices
have you seen so
far? will it be prohibitively expensive?

Sweet.
Let me know if you come across a good value
variable displacement pump or
motor.
I'm not having an easy time finding those on
surplus center and they're
well-suited to vehicle applications.
Proportional/servo valves as well, likewise.

HYDRAULIC POWER
Complete Hyraulic power unit $299
http://www.northerntool.com/shop/tools/product_200329758_200329758?cm_ven=n…
vs
11GPM 3000PSI hydraulic pump - $90, would
need a motor and coupling, or a
clutch/gearing to use power from an engine

Hydraulic motor $125

1.5" bore, 10" stroke - $50

2.5" bore 14" stroke - $60
http://www.amazon.com/Mighty-Double-Acting-Hydraulic-Cylinder/dp/B009LQIXJ4/
this doesn't include valves - there
are manual and solenoid easily
available but I would like to also develop a standard servo-actuated ball
valve
