Great with dealing with big heat and load but will crack up in a big way with det.
Good tune and your not going to have a stress with them.

Re: Hypereutectic pistons??
The biggest drawback of adding silicon to pistons is that the piston becomes more brittle as the ratio of silicon is added. This makes the piston more susceptible to cracking if the engine experiences pre-ignition or detonation.
The up side being lower thermal expansion and resistance to heat.
Look at it this way. They are stronger than nomal cast pistons but weaker than forged pistons.

Re: Hypereutectic pistons??
Cheaper than forgies, too
I'd rather spend whatever a good set of hypereutectics cost and still be able to pay shit
off, save for rego and eat than blow my budget on a cheap set of forgies

Re: Hypereutectic pistons??
forgies are worth it if you want big power aka over 220rwkw thats prob the limit of hyper pistonswebby wrote:Cheaper than forgies, too

they are worth it and forgies are only 8 to 900 bucks i mean thats cheap compared to some of the other motors on the market
just a thought
man always with your 2 cents , what about 5 cents next time man i need more cashlpgalant wrote:those pistons rnt hyperutectic in the pic, there acl duralite, standard replacements, ive used them to, my 2 cents worth lol

i want 300 to 350 RWKWS so forgies it will have to be lol. jet is punching about 200 maby a bit under on standards i believe as she doesn't rattle on cold startup.

Re: Hypereutectic pistons??
Hey fellas, As I have stated many times, I am currently using ACL hypereutectic pistons in my car and I do Have roughly 300rwkw or 388hp in the old speak.
In my experience, These pistons do not crack when there is detonation. They melt the edges away - meaning that if you have bad tuning, or something fails and there is a lean out - the thing won't shatter like a forged piston and ruin your bores.
30psi, boost, nitrous, 10 sec passes, powerskids in top gear. I swear by the ACL's

Re: Hypereutectic pistons??
that is a good reputation for the acl pistons. i have a standard set in my scorpion and never had a problem and i have a set of hyper's in the shed ready for my efi build, starting very soon.
