    I'm not the one to answer this but if I had a choice, I would NOT use it with hyper pistons!

    Not sure I even like them without nitrous!! Yes, they are brittle! I have a ZZ1 Chevy 350 I bought with two broken pistons just from detonation alone. I don't know what was done to the motor before I bought it but it is VERY low miles and perfect other than two broken pistons.

    I actually think I would run cast before I would run them but forged is always the best bet.

    NOS on pistons

    I had run a 200 shot on those pistons for eight years. I had no problem at all,as long as you run a good fuel suupply.The car went from a 11.78 to a 10.56 at 124mph. Do not go over 200 on the NOS at all.I sold the car and the guy put on fogger kit and blew it up the first touch of the button,250 pill KABOOOOM. :3gears:

    I like his answer a LOT better than mine! I guess I should have cut it short at DON'T DETONATE THESE PISTONS!!!

    NOT a good idea for ANY piston but the hyper-eutectics won't put up with it AT ALL!!

    I also think nitrous has gotten a bad rap because of people NOT doing the fuel system right or paying a few extra bucks for safety features like low fuel pressure cut out, etc.....

    It can be cheap HP but some just try to be TOO cheap!!
