I wonder if these pistons can be made of magnesium. Magnesium is lighter than aluminum, about 2/3 density of aluminum, but has about the same strength of aluminum. So perhaps it can be forged or at least shot peened to increase its strength. I think Porche has used magnesium for the engine block but I'm not sure for what part. Anyway, I strongly believe these high compression pistons can be used with mild boost from 12-15 psi. 10 psi is under estimation. For the same psi, it can gain a lot more hp and tq than lower compression pistons.
