One quick question about redlines... what is the highest a stock internal D16z6 can rev up to? Peak HP is at about 6600rpm and the tach shows the redline at like 7200, so im wondering if its safe for the engine to run the rpms up higher or will I damage the internals? Also if i do put aftermarket pistons and rods can i rev higher?

 

theres really no point in going past 6600 if thats peak power.
