One of the problems with the Chinese and Russian Magnetos is the placement of the capacitor within the coil. The coils run hot which degrades the capacitor. If one looks at the Mallory Super Mags and Sprint Mags the coil is outside the magneto. Looking at the top Fuel dragsters and Funny Cars the MSD Magneto coils are outside the magnetos. When ever high currents and coils are involved heat is an enemy. Eventually even the Vertex Magneto was available with an external coil. The Taylor Plug wire used in the auto conversions is not really a resistor wire but is a spiral wound wire which somewhat defeats the unwanted radiated RF energy, due to the use of finer wire and the spiral winding adding to the effective wire length the resistance is higher than the Russian of Chinese wire.
