Speaking to various engine builders forgies with moly rings are not as tollerant to daily driver cold start/go driving as casts and hypers.
Forgies for excessive nitrous (>150hp shots), otherwise hypers are OK.
What cylinder pressures (HP levels) would warrant forged pistons for a naturally aspirated setup only?
