What does "HYPERUTECTIC Pistons" mean?
I wonder what "HYPERUTECTIC Pistons" means???
What's the difference to cast pistons and forged pistons?
(I know what forged and cast means but what is Hyperutectic??)
Thanks
Olivier

What's the experiences here?
What's the difference from one hyperutectic to another?
KB seems to be a good priced set. What about other manufacturers?

I've had the Keith Black's in my Z28's 420HP 383 with 10.5:1 CR for the past two years. I have had no problems. I think that in terms of quality/price, they are a good product.

Speed-Pro (aka TRW) also has a nice selection of hypereutectic pistons for most popular engines ... I have a set w/ coated skirts ... quite pleased. Prices tend to be a bit less than KB.

I've always understood the hyperutectic pistons as being made with an alloy that provides for a great compromise between the sealing properties of cast pistons and the near strength of forged pistons. Forged pistons are great, but you get that cold knock. Cast pistons are fairly tight (no knock), but they aren't as strong.
With hyperutectic pistons, you can run real tight tolerances. Plus, I believe the Keith Black hp's and others are treated with anti friction coatings on the skirts.
Hope this helps. Now I'm going to read the links to see if I was right...
