The resistor limits the current to the coil, to prevent the coil from
overheating. If the coil you're using was originally intended to be used
with a resistor, then keep using that resistor. If you're using a
performance coil that is designed from the outset to be used without a
resistor then you can leave it off.
Pertronix claims lots more energy from the coil when it's used without a
resistor, and that's true, but if you increase the coil output to the
point where it slowly burns through the insulation then you're going to
be stuck on the side of the road at some point, most likely on a hot
day.

Subject: Ignition
Here's technical question for everyone. I just decided to toss my
points from the old autolite dual point and go with a pertronix
ignition. Pertronix suggests running a straight 12v right to the coil
and bypassing the resistor. I'm sure more than a few somebodys out
there have gone this route. Right now I have the pertronix hooked up to
12v and the coil still going through the resistor, seems to run fine.
Does bypassing the resistor make a difference? Should I just jump the
12v on the resistor right to the output to coil? That way I could leave
the resistor block in place for originalities sake. Why is there a
resistor to begin with?
