My 499 840 hp idled at 650 with instant throttle response in gear, timing all in at idle, but was maybe 10 degrees starting so it wouldn’t kick back. 7320 dominator. No little stuff in this engine, I could put in in gear, get out and walk around and it would just sit there. By the way it’s an engine not a motor, a motor is electric.
Forgot to add total was 37, never moved it to see if it was better anywhere else.
