REV-N-NATOR vs MSD Street Fire CDI

????? I'm not familiar w/ the "Streetfire", but I don't know any capacitive
discharge ign. that uses the ballast resistor. The only purpose for the ballast is to protect
the points/std. elec. boxes and coil at low rpm's that use charge system voltage saturation
to power the coil primary. CDI's transform & discharge capacitors sending 100's of volts to
"bombard" the primary side of the coil. This increases the current energy as well as volts
across the plugs.And as the moniker implies "Multiple" capacitors discharge for more than
one spark event at low speeds. I am considering the Rev-a-nator myself, and am curious
to see more member input here w/real-world results,so far so good.
:coffee2:
The MSD Streetfire box is a MSD digital 6al with a different cover, and $50 cheaper than the actual digital 6al

So here is a question? Is it normal for the ballast resistor to be 200* while running? I'm seriously considering the MSD, mostly cause I already have a good coil, and I'd be ok with eliminating the ballast..
