Hypereutectic pistons and failures related..

ran them and beat them to death for years in stock and super stock, stock car racing, they wont take a hit, hit the valve and you'll break one, too tight a ring gap and you'll seized the piston land and seperate the piston into pieces....however, i would run them again in a stock or super stock class anyday, cheap reliable power on a budget, i wouldnt hesitate to use them.......however there is a hp limit to them, under 7k and under 500 hps they will live, once you get pass that point, time for real pistons and real rods, unlike most people I believe a cast crank will take more punishment than a steel crank, a steel crank will not twist, a stock cast crank proved to be reliable for many years in 450/500hps stock car motors, however they have a fatigue point, about 2000 laps we would throw away.....take a hard hit, seem like a cast crank would survive a steel one would crack or snap in half.....

it is a double edge sword, pass the 7k rpm point and 450/500hps, and you better have good stuff if you want it to live and be reliable....

speed cost money how fast do you want to go
