i knew that was a reason to cut them for lighter weight, but i thought you was talking about compression when you was saying to flycut them, it also helps drop the compression a little when your talking about a BIG boost motor Johnny, though with a .010 longer rod you dont loose much compression, cutting the skirt down too much causes piston rock and ring flexing, and will lead to broken rings or scuffed cylinder walls. you can cut factory LBZ pistons all ya want but it cant compare to a special built custom designed racing piston. factory pistons are also hollow compared to the racing pistons.

It does reduce the compression slightly or even quite a bit if you want, which seems to be the trend for purpose built diesel race motors making big boost. There are ways to regain the compression if desired. We do have purpose built race pistons and rods for the DMax. Nasty Girl is running the fly cut LBZ pistons. Actually most factory pistons are Hypereutectic which is not hollow but they do provide some flex.

I missed this post somehow and boy did that have me lost.
I remember hearing about this stuff now. Shaving down the piston faces and playing with the rod lengths to get that "perfect" compression ratio depending on what you're running and what you're using it for. I had no idea that shaving the face would affect lateral movement and all of that though.
It's interesting stuff.
I'd take a guess you probably couldn't shave a diesel piston skirt much before it would try turning sideways on you. Are guys doing anything like cross drilling the skirts though?
