Good Idea but effectively the same thing is happening
I had to increase the sim.frequency to 200 to get it to work on my comp,
the gears were slipping
On my 4 stroke 9 cylinder radials the cam ring is turning at 1/8
crank speed but the lasers still only have the same amount of time to do their job as if the cam was only turning 1/2 crank speed
Upload all you want far better than the avalanche of newbie junk we have been buried with lately

Yeah you're right.
Hmmmmm I'm really not sure what else I could do to change the collision layers of the balls more reliably. I'm sure it's something really simple though. Or maybe I've just reached the the limit of how fast this thing can go in this frequency

So I ditched the lasers and went with normal ball collision and I made an entirely new engine from scratch. its running at a perfectly stable 60 rads with no brakes or anything.

It's so smooth that I thought the engine was glues to the background, but it was actually just resting on the ground

I'll upload it in a vehicle this time rather than just the engine by itself on on my little test platform lol
