Forging Pistons and Thermal Expansion: can't find data to support it.
I meant piston-to-wall clearance. Minimum, not on the thinner part of the camming. The ten-fold increase in clearance was from a Subaru STi piston which has stock piston-to-wall clearances from .0000"-.0009" listed as stock. That is where I'm getting the "ten times" clearances. It is a...- SaabTuner

Forging Pistons and Thermal Expansion: can't find data to support it.
So for a long time I've been vexxed by the explanation given by piston makers for the increased tolerances in forged pistons. I've spent many long hours scouring matweb for any evidence to suggest that the forging/pressing process significantly affects the thermal expansion of an alloy in any...- SaabTuner
