WHAT LIMITS THE MAXIMUM ENERGY THAT AN IGNITION SYSTEM CAN PRODUCE?
From an electronic standpoint, nothing. From a practical standpoint, after a certain maximum limit, more ignition energy does not improve combustion or horsepower. More energy does nothing more than put added stress on all of the components of an ignition system. The weakest link in a single coil system is the arcing between the distributor cap and rotor electrodes. These components will deteriorate rapidly in a very high energy system. To obtain very high energy and retain durability a DIS™ (Distributorless Ignition System) that eliminates the cap and rotor must be used.
