Good Hyper piston?

[mytight95]

I was looking at summit.com, and i looking at the keith black cnc'd version, and the speed pro cnc'd version, they are about 21$ a piece. That seems pretty cheap, are these good quality, is there any specific ring landing size i should look for? I want 10:1 compression. Do i want dome, or flat tops? Is one or the other better?


just general education is needed here.......and i want a floating wrist pin, or a pressed wrist pin



thanks

i dont see whats wrong with it...

poeple always seem to say that hypereutectic pistons are bad and will break easily. which i dont think is entirely true. from what i am told they are perfectly fine for a N/A motor, i hear that if you have a SC or nitrous they may break or something.

But as far as performance and etc they arent different. You couldnt tell the difference.

if anything they may help you, they expand more than forged alum and will keep a better seal with the wall and prevent blowby

this is what i have been told, if i am wrong please correct me...

They can't handle the detonation as well as their forged brothers can. But, with a good tune, there should be no detonation.

i have never had a detonation issue, I AM going with a hyper piston, i was just wondering what the best kind to use would be brand wise etc...
