Performance High Output Ignition Coils. Do you need them?

5/10/2018

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.

Cycling is something that I am passionate about. I love that you are giving new cyclists some information that they can use to feel a bit better. I believe that it is a must for us to do this if we want to make our lives a bit better. I am sure that there are people who do not actually believe this, but I am fine with that. I just want to see how far you can go, that is what I want to do.

    I have been involved in mechanics and motorcycling from a young age. I formed Cycle Improvements in 1981 and still have the same passion to learn today as when I started. Hope you find this blog interesting and educational.
