Thanks, guys. I want to run two hydraulic motors off a single pump. I'd like the vehicle to run 25mph, which means I would need a pump running 200 rpm if going direct drive.

I found one that is 200 rpm @ 1000psi, 9 gpm, and 1230 lb/ft torque and 10 cubic inch/rev.

So, I would need a pump that delivers 18 gpm. That is quite a bit.

I found a calculator online and figured I could drive the motors with a 10.5 hp engine. Stan, your equation verifies that, also. Just need a pump to mate to the engine.

How does cubic inch displacement work? The motors, combined, would be 20 ci/rev. I'd need a pump that displaces 20 ci/rev?
