I have seen several on this forum building hydraulic pump style dynos.Several have attempted to use a stepper motor on the flow control valve.They seemed to struggle with their design and asked questions, but I have not seen a working version posted.Here is what I have put together for kart engines. (mainly 15-30 hp)34cc pump @ 3000 rpm1" input line3/4" output lineI initially purchased a 3/4" flow control valve, but I also now have a 1" valve. Some say the smaller valve is harder to turn and I can use the larger valve if it helps.My question is what size stepper motor have people successfully used in a similar application?Jeff
