- Speed-Pro developed Powerforged Pistons, and set the pace in powerforged technology. The high silicon VMS-75 alloy is found exclusively in pistons "powerforged" by Speed-Pro. Up to 3,000 tons of force forges aluminum slugs into the basic piston form, which creates a grain flow pattern in the structure providing excellent strength, ductility, and heat dissipation.
Note: All compression ratios are approximate. They're figured with a gasket thickness representative of those commonly used.
