I have set of very lightly used Diamond piston that have literally seen boost for only one dyno session. I made some changes to my motor and ended up with a different piston design. Pic is spec sheet from Diamond and these pistons were made for a lot of power and cylinder pressure. I also made them change the valve relief and put more material in the ring lands which is why the dish looks a little different.
