A discussion has taken place concerning modifications to the Power Cube for the upcoming OSEBG LifeTrac build. The question was raised about powering the LifeTrac with a single more powerful Power Cube instead of two current Power Cubes.
Similar Hydraulic Power Units
Foster 35 HP diesel hydraulic power unit @ $18,000 and 3100 lbs (compare to Power Cube @ $26,000 and 500 lbs):

Engine
Diesel engines are heavier. For example this 26.4 HP engine weighs 171 lbs dry and without radiator, fan or water. It is comparable in price to some gasoline engines ($2195):
Of course, more power means more fluid flow and heat dissipation. The hydraulic plumbing must also be considered and adjusted if necessary. The pump will have to change as well.
