Hypereutectic running clearance
Web27 dec. 2012 · Because of the unequal thermal expansion coefficients between materials used in the engine (i.e. pistons vs engine block). Or uneven geometric thermal expansion inside components (i.e. pistons being oval when cold, but round when hot). All of this to achieve "optimum" clearance in running conditions.

WebBack clearance is the measurement of the space between the inside diameter of the ring and the base of the piston groove, when the ring face is flush with the ring land of the piston. Optimum back clearance for a racing application is .000". In other words, back clearance should be as small as possible without having the ring face protrude beyond Web1 jun. 2005 · A third manufacturer said some coated hypereutectic pistons may be installed with as little as .0008″ to .001″ of clearance. On a Chevy LS1, they recommend .0025″ to .003″ of clearance. So it all depends on the application, the type of piston, the alloy used and the piston profile.
