    those look nice, but ill always have a thing for the CP pistons. I have built many high HP/Big boost motors and have yet to see them fail, all though I run a different ring set and different wrist pin than what comes with the normal off the shelf kit:

    those are also CP pistons and are in sleds running 45+ psi
    the wimpy stock style skirts crack/brake off under big boost
    so slow91 have you been close to 45psi 600+hp

    personally no, but I have built Darton/cp/carrillo motors for guys running big boost.

    Yes I have a skidoo that is going to the dyno soon that I will start at 35psi
    and may get close to 45 ....I will only go to or over that if a race depends on it

    the reason for this post is to see/find if any one had real high boost pistons for the 1500 for sale
    or maybe find a stroker crank/rod/piston combo
