T (charge time - milliseconds) = L (inductance - mH) X I (current - amps) / V (battery voltage - Vsat)

Since the MSD coil has a higher inductance, the charge time will take longer to reach the desired
current/energy, potentially limiting the max rev point. This should not be an issue for non-race
engines.
