Re: Force 150 spark plug question
An ignition system designed to output 33K voltage will output 33K voltage regardless if the plug is SGP or not. the only difference is the timing of the arc or spark. If the plug use has narrower gap, that means the arc will happen before than originally designed but also of smaller magnitude but the coil output voltage will still be 33K volts. As for the current in the preceding scenario of using a narrower gapped plug, will be less compared to designed wider gapped because the arc discharges the capacitor well before the designed curve of the current. So does that mean if the plug used is of wider gapped it stresses the ignition system? NOT AT ALL! Because the system was designed as such. So will the use of plugs with narrower gap makes the ignition system less stressed? Again, not at all. The only thing that changed when you use narrower gap plugs than those designed to start with is that the arc happens way before than designed. AND IT DOESN'T HAVE ANYTHING TO DO WITH STRESS ON THE IGNITION SYSTEM AS OTHERS CLAIM.
What about if we go the other way around, i.e. using a wider gapped plug (than originally designed) in a narrower designed plug ignition system? Will such setup put stress on the ignition system? The answer is yes. With wider gapped plug, there is a possibility an arc or spark may not be accomplished due to lower working coil voltage. As such, this will prevent the capacitor from discharging hence making the system inoperative. This is the very same reason why CDM's are damaged when plugs are pulled and not grounded when troubleshooting.
All coils are set to have certain output (H.V) their primary will be of cause 12 volt in auto and marine unless it is a 24 volt system, it will depend on the secondary coil to what voltage output it is. The voltage output will never change in a coil unless it is faulty or unless you input a different voltage on the primary.
So in theory if you do put std plugs in place of a surface gap plug, you would make the coils working current lower, not it's voltage. If the coil is designed to work with SGP you could possibly reduce the amount the coil is working (Power = Current * Voltage)with pronged plugs.
Also it was I who said the SGP had a better spark as noted in my manual. But also I understand everyone's personal preference in how they run their motors and I am not suggesting your wrong by running the std plug. Just disagree on your theory of the SGP, nothing wrong with a good debate anyway
