Think the way to make one is just go full out good to say 10K without breaking up. If I had the time I would give it a shot just to many Irons in the fire now.

They (manufacturers) don't know there is a need. The tough thing about doing something like this is the design and set up cost is the same whether you make 50 or 50,000. The end cost of the product is hugely different between the two though.As a resource on this quest I have a brother that is an electrical engineer who has been designing computer chips for the last 15 years. Bet he could draw up a design layout for our boards.
Knowing what internal parts we would need, could probably build and solder together parts from Radio Shack to get a first rough draft off the ground.
Like the idea of a 10,000 rpm no limit version just to keep it simple.
There are lots of smart people on here that could guide us along to the next steps to make it happen.
I just have a real hard time believing in today's tech world that the manufacturing industries have not been able to come up with a new reliable ignition module off of the mopar original design.
With manufacturing coming back to the USA now, good possibilities to get them done. We might have to show them how to do it though.
R is resistor, D is diode band side is direction of flow --->|- C are capacitors , triangle 3 pins are transistors (BCE) you could pop the board out and show us the back side traces and we can come up with a schematic. Once you get the schematic out there, you can overbuild it to your taste, (300V TO-3, Massive isolated heat sink, cooling fan, etc) I know there is a handwritten one out there somewhere. IIRC @KitCarlson made an ignition circuit and there are DIY projects out there. I think the dwell circuit is only thing not a few transistors cant do switching wise. This one has no dwell circuits but look how simple the switching is, 5 components! There are even digital projects out
there. Programmable Digital Ignition

The heat has to get out of the case. Vents or a expansion valve?
Talking about heat sinks, what is the operating temp of the transistor and the unit as a whole? Would there be a benefit to installing it in the cabin and getting it out from under the hood and away from 600° exhaust?
I'm surprised that the aluminum u shaped channel even dissipates enough heat This is a heat sink. But it will just absorb heat if the underhood temps are higher than the transistor puts out.

I have to ask this what is every ones electronics backgrounds? I was a Avionics shop Chief in the USAF for 18 years. Back when I started we actually repaired the internal board in the boxes. Bet we have some serious knowledge here on this thread
Lots of good work on this. Has anyone examined a failed box to see what part actually failed? It appears that we are focused on the power transistor as the failure cause. I agree that it is a likely culprit, but do we have any evidence? My average blindfolded with a shotgun isn’t all that good....
