RE: 80k volts to plugs!
By John - 12/29/2004 11:12:33 PM; IP 142.177.99.152
Even with 8:1 CR, your measurements seem low. Regardless, seems to me the vacumn advance error would play a huge part in your low power problem. If gas mileage isn't your worry (hobby car, etc.) I'd suggest doing away with the troublesome thing and using a mechanical advance only dist. Works for me. Now about that 80Kvolts......well, a spark gap and the conductivity of the gas/air mixture in the gap dictates the voltage across the gap, not the coil. Sort of like a zener diode for those of you familiar with them. The rest of your system takes up the difference. In most cases this is handled by your resistive plug wires. The 80K won't burn up the plugs, but it may not give a spark of good quality. You need duration, and if that is sacrificed at the expense of abnormally high voltage, then you may be having ignition trouble. Although maybe not for the same reasons as Mikee Likee, I have to concur that maybe your ignition system is more hype than performance. What exactly have you got there anyway?
This thread, so far...
