One comment I wanted to add for future heat sinks that members here might wish to fabricate/install on their distributors... don't be afraid to extend the heat sink beyond the "front" of the distributor base. The larger the heat sink (within reason) the better.
This is the heat sink I made and installed 15 years ago. Still using the same ICM all these years later!
And yes, I know the long screws look goofy. I left them that way on purpose to aid in the cooling... and besides, they can't even be seen when the distributor's in place.[This message has been edited by Patrick (edited 06-04-2023).]

Both you and vintage nut have made the assertion that adding a heat sink will improve on the factory design. Did you not? If not, what's your claim then, that A) "it will make no difference adding this heat sink" or B) "it will actually make it worse adding this heat sink"? It seems like you're just arguing for the sake of arguing at this point. If you don't believe it will improve upon the design made by hundreds of GM engineers over dozens of car lines and 6 divisions, then why did you do it? To make it look cute?
His heat sink is about 1 sq inch. Yous is larger. So now your second claim is 1) Adding a heatsink is an improvement to the factory design considered and rejected by hundreds of GM engineers, AND 2) The bigger the heatsink, the better. e.g. If a 1 sq inch heatsink is good, a 1000 sq in heat sink is even better. Again no one has shown any evidence that it works, let alone that it works even better as the heatsink gets larger.
Further your assertion that because you have a car with a cute little heat sink where the module hasn't gone bad means your cute heatsink works is dumb. I have a 35 year old IM without a heat sink that hasn't failed yet. So using your logic, the heat sink is ruining them quicker? Further I live in a much hotter climate I imagine than you. Again it's dumb but I'm using your own logic against you.
So again, if you think youv'e improved upon the design of 100's of GM engineers, the burden of proof is on you to show it. I'll stick with the wisdom of the engineers at this point. If you want to use empirical evidence rather than seat of the pants "it looks cool so it must work", then I'd be happy to consider it with an open mind.

Even when you're told in plain English what size the heat sink is, you continue to report the wrong size. Is your math really that poor, or are you simply being obstinate?

Oh, the irony.
Run a google search for ICM heat sink and you'll see plenty of examples of factory ICM heat sinks from GM, Ford, Audi etc. But of course, you know more than engineers from around the planet.[This message has been edited by Patrick (edited 06-05-2023).]

Obviously reinhart, you missed the point of well-known ICM failures, plain facts and rationale, but rather struggle that your  is 'accurate'.
We all get your ‘analysis’, please move on……VN

Sorry but based on his own picture. I can say for a fact it is not "2 sq inches". It may have started life as 2 sq in but after the mods it certainly isn't. I was trying not to further embarrass Nut. I just grabbed a spare distributor and there isn't even 1" of distance between the underside edge of the pole and the flat edge of the base which is why he had to cut a row of fins off to get it to fit. Further accounting for the significant area removed by the screws it's less. So did you even look at the picture?!? LOL More bad guessing Patrick? At best it's 1.5 sq" accounting for the removed fins. Or in your mind does it still count as a heat sink area with fins removed?
Regardliess you are really good at missing the forest for the trees. Rather than defend your absurd claim that you know more than GM designers you focus on whether the cute useless heat sink is 1" 1.5" or 2". You avoid the massive problems with your claim and try to distract with your irrelevant focus on whether the heatsink is 1 sq" or 1.5" sq". Pretty typical pattern of behavior by you and shows you have no leg to stand on as to whether the cute little thing works or not.
I checked the google image search you sent. I had previously said "I'm unaware of any manufacturer that had a factory heatsink on an IM". So I stand corrected out of the thousands of car models with distributors it looks like there were perhaps two or a handful of apps. I never said I had scoured every single car on earth and knew for a fact than no one anyone ever tried it. I think we can agree that at best 1% of car applications used one. Is that fair? Again you love focusing on the tree and miss the forest. It looks like there was one distributor module application that had a heat sink from Ford and one from GM showing in your search results. So the fact those two automotive manufacturers used it in basically one application only reveals 1) They knew about the option to do so, 2) They decided it was only helpful in the rare 1% of the time. We don't know the circumstances for these applications. Were the modules near an air duct etc? Were the modules of a different design? So does that hurt or help your argument for the Fiero?!? It hurts it, because you now confirmed GM knew about the idea and didn't use it and it means they didn't see any improvement when testing or modeling. 99% of the images in the search were jerry rigged by seat of the pants people such as yourself thinking they were smarter than the hundreds of GM engineers.
So again. Any proof your cute little gizmo works or is entirely based on your narcisistic belief that you're smarter than 100 GM engineers?

I'll take that as a "No" to my question:
"So again. Any proof your cute little gizmo works or is entirely based on your narcisistic belief that you're smarter than 100 GM engineers?"
Look on the bright side, although useless, you do have the cutest Fiero distributor around.

Just like an "ad hominem" attack is a non-argument, saying that something was designed by hundreds of engineers is irrelevant to the technical issue at hand.
A technical debate should be debated based on the technical issues only.
The credentials of whoever designed whatever apparatus have no bearing.
Branching off to the "hundreds of engineers" comment, I doubt that it took hundreds of people to decide upon a cooling method for the Fiero distributor.
Greg Locock over on eng-tips once wrote that him and one colleague were the mechanical engineering staff during the design of the Ford Capri. The duo took care of everything, suspension, steering, doors, windows, body.
It's pretty weird to think of automotive engineers as wizards whose designs should not be touched or criticized; we're just... people. Don't put us on a pedestal.

I believe the results of 15 years of service with zero failures says that the solution for the elimination of excessive module heat has been solved with Patricks heat sink design. . ------------------
