Nice circuit. I am surprised the ignition coil does not short. Do you know what kind of ignition coil it is?

Thank you @kooler! I will try to find that kind of transformer.

the coil is from a dodge ram 1500 5.2 liter

the little ford coil doesn't work as well for voltage but has some current on it like real red spark..

Thanks. I will try to get one. The JT part of your circuit looks brilliant. The diode should get the transistor to turn off fast - thus big voltage spikes. It should work great with a flyback transformer. I will be trying it as soon as I get some parts and some free time.

PS - I hope you are recovering from your fall.

thanks,
my back is healing slowly..
i made a small mistake in the schematic
tinycad did not put a dot on the emitter to negative.. didn't know if many people saw that.. (pese pointed it out.. thanks man)
yea the diode does make the cutoff alot sharper..
the cap on the base just reduces heat and gives a little more power .. you won't need a heat sink on the transistor.. it stays cold..
you can run this on a 9 volt battery.. but i was using a wallwart because 9 volts cost alot..

ps.. this circuit will short out a m.o.t. in the first 5 seconds.. but if you dip it.. you can get alot better sparks than the ign coil..
