I have been doing a great deal of research on internal work and I have a few things I thought I would posit for discussion.
1. Piston deburring, do you do it. Why or why not. One area of concern/interest for me is the bowl edges. Not only are they sharp and therefore crack prone, but as the piston reaches TDC the air is forced from the area outside the bowl to the bowl. A smoother transition may help in this transition and effect a more complete combustion.
2. Bowl work, any ideas or things that you have tried or wanted to try.
3. Ring gas ports. I don't think that this is needed because of the nature of the combustion in a forced induction compression ignition event. But maybe it is???
Just some thoughts. These are things that many builders in the gas world use so I thought I might bring them up....
In the past I have just removed the lip to allow for a bit more timing in the injection event and still have the fuel spraying into the bowl. I can make the argument that the "lip" needs to remain in the bowl design and just the general shape enlarged with a bit of a radius on the sharp edge to help with heat build up and cracking.
I think I see it the same way. A small radius on the sharp edges is more than enough. There is a reason the bowl is shaped the way it is. I see that you did change the center point in the bowl, kinda looks like a cummins bowl.
Pretty sure they come like that. 12V's and 7.3's only had two valves, everything is just slightly set off center in the head, so the bowl is off center.
That makes sense - and what I was guessing. I really want to understand how that helps performance and such - the whole system and why one component needs to do something. One day - I will.
So really the one on the right would not be needed if your running a stock cam and pushing for maybe 600 max HP. I can understand slightly machined ones like the one on the left but for something that is a DD and stock cam does the one on the right really serve a purpose?
I bought a reduced compression mahle and used it .
