MSD Blaster 2 Coil question

The MSD 8202 will have an estimated peak current of 7.4A based on a typical ballast resistor of 1.2 Ohms. The standard coil would have a peak current of 5.8A, so the increase of current for the blaster is about 28%. The 8202 also has about 20% greater inductance. Since the stored energy increases as the current squared, times the inductance, the 8202, has the potential of 2x the spark energy, excluding losses.

The reason for not using the coil is the additional stress on the output transistor of box, due to both peak current and greater peak voltage due to additional inductive kick. Results may vary, a car with aged wiring and crusty bulkhead connectors may never reach the peak current due to voltage drop losses, and box may survive. My experience in working with electronics is great reliability when keeping within component specifications. Exceeding maximum specifications leads to failure.
