=Power Cube 50=

Create a more powerful power cube utilizing a mid-90's era Geo Metro 1.0L 3 cylinder engine.  50 HP is plenty of power indeed for a small tractor, these engines are extremely compact.

Things to consider:

# making power cube a little larger to accomodate?
# water cooling radiator
# hydraulic cooling radiator
# blower
# fuel tank
# hydraulic tank
# a pump like one of these: http://www.longsurepump.com/upload-images/LS-20.pdf <- 25cc variable displacement axial piston pump

GPM X PSI X .0007 = horsepower

GPM = Horsepower/(PSI*.0007)

GPM = 50/(3000*.0007)
GPM = 24 GPM

RPM X Pump Displacement / 231 = gpm

RPM = 4000 ( 30+ HP out of the metro engine)

Pump Displacement = GPM * 231 / RPM

Displacement = 24 * 231 / 4000

Displacement = 1.39 Cubic Inch = 22.7 cubic centimeters
