E58 400 plus HP Dart sport build

If your engine builder has problems with KB hyper pistons breaking, you need a different engine builder.

I wonder about this concept. Dan Dvorak swore against Hypereutectic Pistons and he was an accomplished engine builder. I remember RRR saying "You have to read the instructions and gap the rings correctly." Maybe these pistons are fragile without extra caution and precaution. Once properly installed (not including nitrous use, or maybe forced induction) perhaps these pistons perform perfectly fine within >>?what?, designed<< parameters.?.

replicaracer43, do you think it is possible that intelligent, competent, engine builders could run into problems between heavy foot customers, liability, and the thinner KB-107's Hypereutectic pistons and operation outside designed parameters?

Though in your favor (replicaracer43), the common denominator IS the KB-107's, among engine builders and drivers.
