>>The reason a cast DIESEL piston can handle 1000hp while a cast gas piston will fail is NOT due to the mass, it's due to the way the fuel is burned in each... A gas piston sucks air/fuel in, fills the cylinder area, piston comes up, compresses hard & just before the top, a spark plug POPS the mixture causing a controlled explosion.. Diesels are nothing like that at all.. The diesel doesn't mix fuel before the piston starts compressing. The diesel begins "injecting" fuel around the top dead center just as the compression peaks. The heat / compression detonates it , and the injector feeds the burning / expanding fire ball as it chases the piston down during it's power stroke. Basically, a gas engine uses a single instant EXPLOSION to throw the piston, where the diesel SHOVES it during a 3 or 4 inch burn cycle... Try to tow a car using harsh yanks on a tow strap VS a steady tug. The YANK might make it move quick at first, but it's hard on the parts. The steady tug is easier on parts & better to pull up a hill..

Yes he did, but they aren't called Hypereutectic pistons in trade, just in marketing wankery speak. They are high silicon based forged Aluminum pistons. Hypereutectic is a marketing trade name.

Unfortunately forged aluminum pistons can't have a steel ring carrier so a piston of this type would be racing only. Forged steel pistons as mentioned in the video are heavier than their aluminum counterparts, however reduced piston pin length can bring down overall oscillating masses of a steel piston assembly to the level of aluminum ones.
