Do we have to go further than that? I can absolutely MELT a forged piston with a mis-tune on nitrous. But on the opposite side of the coin, Hyper-craps will tak a bit of abuse, but not A LOT!
FWIW, I'm beating the PISS out of my hypers, all motor. And so far, so good! They're getting swapped out for a set of forged slugs this winter (perhaps 9.5:1 ratio????? Hmmmmm)
Think of it this way. You're hitting that piston with "X" amount of force when the fuel/air ignites. Think of "X" as a sledge hammer. In a normally running engine that sledge hammer, or "X" hits the entire top of the piston, and the world is good.
If detonation occurs, somehow a 16 penny spike ends up on top of your piston, and "X" hits the nail, and ALLLLLLLL that force ends up in one single concentrated spot on the top of your piston. NOT GOOD.
Forged pistons are a lot more forgiving on the whole detonation thing, while hypers are not. Hypers have a higher silicon content (which is used for longer more reliable street use) but if your "tune" is off, they DO NOT like nails! So basically, whay Brian said is true, if you know what you're doing, you're good to go. Margin of error is significantly smaller with the hypers.
With me?
