Streetfire Ignition Only Likes Accel Coil
A primary side of a regular coil is designed to run on a continuous 8volts or so, with the negative side switched. The coil in this system is just a transformer with about 3000:1 step-up ratio, or more; so if you input 8 volts, you might get 24000 output.It will run like this for several decades.
But a Capacitor Discharge Amp, likes E-core coils. Most CDI systems are firing 400 to 500 or more volts into the coil, multiple times below 3000 rpm. Stepped up by a regular coil, this might be capable of delivering 120,000volts, But the wire inside that regular coil, while possibly surviving in single-strike mode, I'd be surprised to see it survive in multi-strike mode; it is a very fine wire.
So if you have a CDI system, you need a CDI compatible coil.
Why then does the SuperCoil survive? IDK. I guess it's living up to it's name.
