Forged or hypereutectic pistons?
 

I pulled my motor apart tonight and found the top ring land gone on one piston. Now I have to figure out what kind of pistons to run. The motor will be a 468 with cast iron rectangular heads and twin turbos running about 10 psi of boost. Should I consider running a hypereutectic piston at this boost level. The inital compression with the hypereutectic pistons will be about 7.5

I'd run nothing but forged pistons.

Isn't 'Hypereautectic' just a fancy word for a cast piston with a high silicon content? :D

I like to build them with the best parts so you can feel good about it when you have the throttles mashed to the dash :D

:evilb: more .02 :D

Forged all the way. All Hyper. pistons are good for is dissipating heat faster, but at a cost of strength. Forged pistons are denser therefore hold heat longer, but take more abuse.

I broke one of those pieces of crap on an under 100 hour 454 rebuild. I will never have that problem again! Forged only.

you want forged turbo pistons with extra thick top lands.

Forged :D

forged is the only safe way to go and i would get a peice made for usng a turbo spend the money now and you won't regret it :D
