Accel plug wires
Reply #18 –
Chrome several 2.3 TC owners used aftermarket High performance coils. Only to have a high compression load miss fire.(SPARK BLOW OUT). But some say the COP aftermarket coils are better than stock FORD. Only issue is the aftermarket stuff has to be comparable in price. Now the High Performance stuff claims more energy. Is that Current or voltage??? If you have a TFI ignition system better be ware as primary and secondary voltage and current load plays havoc on the TFI system. If you want a TFI system to work better keep it in tune. Otherwise some night the flat bed and you will be good friends. Also many car companies specify special plugs. Installing the wrong plugs in some NISSAN'S will blow the coil packs. So be advised bigger is not always better. just me could be mistaken!!!
NOTE i spend many hours on the cylinder scope and scope patterns. I have found no difference in spark voltage with or without a high performance coil. With a gap of lets say .040 the coil can only produce so much voltage. It seems like the gap dictates the voltage. If the gap increases the voltage goes up. This is void of the mixture present. Because that does also make a difference. Case in point an open plug wire will blast the scope voltage pattern of the screen. When i see excessive voltage on a particular cylinder it normally means a bad wire or excessive gap or a mixture issue in that cylinder. So if you want to increase your voltage at the plug increase it's GAP!!! That is what the HEI ignition systems did. They raised the voltage and increased the gap. If you are running a high performance coil capable of more voltage increasing the gap is where it is at. If not the stock system is totally adequate. But you put xcessive loads on the primary trigger system. And that blows modules left and right. Stock modern closed ended wafer coils are at their best. Other than COP the coils are able to produce enough spark for just about any engine combination. Thanks
