I am currently running a stock distributor on my 2.0 w/ Djet. It has the pertronix ignitor module made for my distributor with the vacume advance. I also had a flame thrower 3ohm coil made by pertronix. I am not sure how many ohms a stock bosch coil is, but my question is...
most high performance coils such as mallory, crane, even the flamethrower (not the one I have) comes with a resistance of .06 or less. Why is this, and what does the ohms do for you anyway. I am thinking to put one of the VERY low ohm coils on my engine to see if any better performance. If you dont mind also explaining why i threw out my ballast resistor when I originally put the pertronix in. (as per installation instructions) what the heck did that do for a stock coil thats not needed for a 3 ohm coil? (IMG:style_emoticons/default/popcorn[1].gif) |

some cars use the ballest resistor when running, but bypass the resistor during cold start. Some British cars are configured this way. this allows a hotter spark during start up, and a lower power spark during running. if the high power spark was used for any longer than starting (ie cranking the motor) the point would burn up. a nice way to deal with a cold start issue
Ohms =Volts/Amps ...... So ohms (resistance) is the value of Volts (potential) divided by Amps (current) |
