Evening all. Just had a thought, performance coils are basically just transformers with a larger amount of turns on the secondary so if i were to use 2 standard coils, i would have double the voltage. 27kV standard? with elec ignition and a flame thrower there would be 40kV but 2 coils in parallel would give 54 kV. Are there any down sides to this setup? Would the dizi cap and rotor arm take more wear? I would imagine i could set the spark gaps larger too? Thanks

DANGER DANGER DANGER!!!!!!!!!!!!!!!!!!!!!!!!!!

DO NOT UNDER ANY CIRCUMSTANCE WIRE THE SECONDARY COIL TO THE PRIMARY OF ANOTHER. YOU WILL KILL YOURSELF!!!!!!!!!!!

no point wiring them in parallel, cant see it working at all, how would you wire the ignition leads. You would still have the same secondary voltage on both of them and it would a watse of time and space.

If you have electronic ignition, use only th coil that it was designed to use, do not fit a higher power coil, it will destroy your electrinic ignition.

There is more to it than what i have put here

If you want twin coils, fit Megajolt and EDIS

im not connecting the output of one into another, you CAN run 2 in parallel which effectively doubles the voltage output (I have done it before just not with a car) I dont want to run megajolt, i just wonder why go through all the expense of the electronic ignition, flame thrower coil etc when i could kick the voltage to 54kV with just a second coil, all the benefits of the other upgrades but cheaper and more effective. Would the dizi and rotor arm sustain substantially more wear? Also im looking for any downsides to using this setup.

Under what laws of physics will two identical 'transformers' in parallel double the original output voltage???????.....................

Like this:



v1 is 27kV or so, v2 is 54kV or so

Anyone tried it? What will i break?

I'm trying to picture how this is going to work?
If the coil wire itself is one leg of the secondary of the tramsformer and it discharges throught the plug and back to ground...assuming the case is the other leg of the secondary...how are you going to connect the secondaries of the coils together in series like that?

The primary sides are easy with the + and - terminals. But those are in parallel.

What am I missing?

if you wire the coils in parrellel, all you'll do is double the CURRENT

if you wire them in series (impossible by the way, as the negative of the secondary coil is internally tied to the negative terminal to stop the voltage floating too high, not seperate as you have in that diagram) then all you'll achieve is that you'll notice your HT leads, sparkplugs, rotor and cap will all break down VERY quickly, as they were never designed for those kind of voltages

It is however, possible to wire one coil normally, giving 25KV, then wire one in reverse (positive earth) to give -25KV. Between the terminals, it should give 50KV. But you'll never get it to work on an engine, as it would mean insulating the sparkplug from the engine, to give it the -25KV charge





If you somehow manage that, let me know

Hmm, now hatching a plan to rubber mount the engine, starter and alternator and use mechanical gauges. Then come up with some seriously advanced system for setting up the dizzy and earthing the casing electrically neutral to the two coils...... Then again, surely electronic ignition might be simpler.

There have been a few funny topics on this forum in the past

I rank this one Number two in my list

[robson]

whats number 1? Ill let you know how i get on

If it works as it is, don't fix it.

[robson]

if only i could stick to that

just buy a nice chromey flame thrower one, mmmm
