brainsboy,

how does a short-rod motor get the piston to move away from TDC faster than a long rod motor? The piston will dwell longer at TDC with the long rod, but it will move faster as it hurries to get to BDC, where it will again dwell longer than the short rod motor's piston.

If the piston dwells longer at TDC and BDC with a longer rod, there is less time for it to go up and down, so it's piston speed must be greater than the short rod motor.
