Hyper pistons do have some qualities like the heat cycles and tighter clearances, and even though there are plenty of guys making power with them, for my money i wouldn't waste my time, for a few reasons..
1, because i KNOW if i build an engine, i'll never be satisfied and eventually i WILL get juice or forced induction, and since my wallet won't allow me to rebuild an engine and swap pistons, i'm gonna do it how i consider "right" the first time, and if my budget won't allow it then i'll just have to save up. It's ghetto but most speed shops do have lay-a-way....a buddy of mine is picking up Vic. Jr. heads tuesday that he got that way...
2, The fact that hypers don't expand and contract...even though that gives tighter clearances and may not burn oil, that same fact means that they don't have any "give" and when they come to their limits, they peal like onions. Also that bit about better ring sealing because of heat cycles....well if you have good quality forged pistons, once they heat up they'll seal just as tight.
Now i do agree that high dollar internals in a stock block is kinda backwards thinking, but every build has a weak link somewhere. Right now the new Z06s are blowing pistons to hell and back, and if you ask me it's because they're hypers. I'm not saying forged pistons don't blow but you don't see Pro Stock cars running 200mph running hyper pistons.
