Thought I would share this as this question came up today. I have customers that want to order a high output ignition coil sometimes to get a "hotter spark" for better performance. What they do not realize is that in almost all cases on a stock or evenly slightly modified motor it will not make any difference. The advantage to a high output cool is it's potential to supply a higher voltage if the motor demands it because of its state of tune. Factors that can cause a higher spark energy are the spark plugs gap, compression ratio, air/fuel ratio....etc. Stock or modified motors will generally never come close to exceeding the stock coils potential. Save your money.
See the waveform below from a Suzuki GSXR that I captured using our Pico Oscilloscope.As you can see the peak voltage requirement is not even 9,000 volts when revving the engine. It is obvious that a 30,000 Volt coil is overkill and not necessary for peak performance.
