The Keith Black 390 Hypereutectic alloy is cast in a permanent steel mold
which makes it possible to build a light weight piston that makes more power 60-0165
and uses less fuel and lasts longer than any other type of piston being made
today. We can now forget about running loose, noisy, oil-burning pistons.
The low heat transfer of the alloy keeps the skirts cool so piston expansion is
minimal. Test engines have run with as little as .0005” (¹⁄₂ thousandth) piston-
to-wall clearance. The combination of a low heat transfer piston alloy and high
compression ring placement increases power and economy. The high ring
placement alone reduces detonation and increases the top ring temperature.
