The myth

WTF is up with SR's blowing up rocker arms? Yes I realize that this has been covered; however, if it's true that they blow up due to high reeving, then why is it that the JDM Silvia cluster reads 9K?! I've heard cases of people reving up to 7.5k and blowing them bitches. Whats your 2 cents on this?!?

everything changes in the higher revs. things begin to vibrate and flex and my guess is that this and the ultimate design of the sr valve train is what leads to the issue

Bouncing off the rev limiter and mis-shifting down tend to be the cause of rocker arm failure. Also anti-lag systems. Hydraulic lifters are part of the reason for rocker failures. Many top engine builders don't believe an RAS does anything - there are plenty of sr's w/ RAS kits installed and displaced rockers.
