I put in a pertronix and thought it worked great. I could even see a drift reduction when observing with a timing light.

Cant figure out why is it blowing the coils, my mechanic say it may be a bad production batch, anyone else using the CV kit? Thanks I have. Pertronics distributor here, just need to buy another coil maybe to match. Don’t know wat to do really. |

Does the coil have an internal ballast resistor? About 4 ohms when you measure the coil primary? No ballast resistor = coil runs too hot and shortens the life.

What is the "CB Performance ignition kit"? Is it a Pertronix and a coil? If so, maybe just try a Bosch blue coil? There's a lot of folks out here doing that.

Hmm - I’d talk to CB Performance. Their coil is low resistance and low impedance. It will pull A LOT of current. A lot more than a Bosch Blue coil. If they designed it for 1 ohm it’s up to them to make sure it can withstand the heat that it will generate.
Not liking 1 ohm primary at all for use with an old school distributor that has long dwell time (time the coil is energized). Low ohm coils like this usually serve only one or maybe two cylinders (in wasted spark application) fuel injection applications. In your application, this coil is trying to serve 4 cylinders. That means the coil is powered with a whole lot more “on” time than whatever application they took this coil from. |

Yep, I ATE a LOT of coils on the RX8: lots of sparks 8500-9000 rpm

Is that an Autolite distributor?

(IMG:style_emoticons/default/confused24.gif) I will try the pertronix for a while. I have it in hand. |

Here is a picture, the price was comprehensive. Based on the suggestion I will try the Pertronics distributor and 009 coil I have it on hand (I am running away from points and condensers if possible) |

My recommendation would be swap the coil only. Why add more uncertainty by swapping multiple components?
