Reply to "bore size Hypereutectic pistons"

Frank, these are the pistons that i warned about in your other thread, your friends pistons probably broke due to spark timing / engine tune. when hypereutectic pistons experience knock, ping or detonation they break into pieces

insufficient cylinder wall clearance is very unlikely because hyper pistons are suppose to run very little (tight), they don't expand like a piston made of 2618 alloy, or even 4032 alloy

do you want your engine to end the same way as his, then use the same pistons i guess?

standard cast pistons are more durable than hypereutectic

forged 4032 pistons are more durable than standard cast

forged 2618 pistons are very durable
