I found a good price on a danfoss orbital. the OSPM 70 ON. Would this work well with a GM pump with a 2x8 cylinder and 42"s? :fish:

It'll be real slow, at only 70cc/rev displacement.

So something 100+ would be better?

(2/2)^2 x 3.14 x 8 =25 cu/in cylinder lock to lock on the big side assuming single ended, less for a DE ram. how many turns you want lock to lock? 2.5? okay, 25/2.5 = 10 cu/in per revolution.
there are 16.387064 cubic centimeter per cubic inch. so a 160 cc orb would be nice.

So I'm having some trouble with the orbital. I'm running a stock ps pump with a cooler and ext. reservoir with a single ended ram. L and R are ran to the ram, with the pressure side from the pump to the orbital. the return line from the orbital is ran back to the ext. reservoir then into the cooler then back to the ps pump. Am I missing something or does it have THAT MUCH air in it? It will turn the tires but its extremely slow and difficult.
