I’ve witnessed that hysteresis phenomenon over the shoulder of a prominent camshaft manufacturer.
It’s akin to watching a snake slither about on hot asphalt – only he survived.

Yes - people don't realise that you just need to change the value of one item e.g. spring-rate to move the critical frequency out of range!Originally Posted by splinter

Some backyard tuning shops don't know what they are doing by raising the rev limit, or worse, deleting the rev limiter altogether.
Friend of mine destroyed a Toyota "Twin Cam 16" 4AGE engine by doing that. You could safely rev the 4AGE engine to 9000rpm with modified valvetrain - but no ways standard.
