Prechamber Mod "Flame" Front
I’m glad to here that people are having fun. The ideas that have been shared so far have been fantastic, and as a result, I am going to reduce the dia of the burn tube its self, just a little bit, in my custom designed PC to increase swirl. I’ll do a couple of sizes as I would be able to increase the ID easy enough if the ideal size is larger than the smallest size I try.
For my next mod I will machine a slot from the left hole across to the right hole, making a mouth.
When I look at the area of the holes of a 60X PC compared to the cylinder displacement, and then look at the 61X PC hole area compared to the 61X cylinder displacement, I see that even with the holes opened up, I'm still on the concretive side. When I look at the area of Jeemu's modded PCs compared to the cylinder displacement, The slot looks good.
I will have some more numbers to post later that pertain to laminar flow of an orifice the size of the PC holes. The point being that hole size makes a difference. 8 small holes will flow differently than three big holes of a total area = to the total area of the 8 small holes. (poorly worded I know).

Hercules,
Great info, I think Tomnik posted similar, (if not the exact), MB PC mods in my other thread. I was waiting to bring them over hear until the idea that MB sanctioned changes was officially challenged. If it hasn’t been challenged by now, I don’t think it will be.
There was another one for the OM615 to address complaints of low power, I believe it said to open up the burn holes in that one, but I have to look again to be sure. I have incorporated those changes into my PC design.
