Does anyone know of an actual member on these forums who blew a motor at 450rwhp or lower? I've asked this several times before and I don't believe I've ever seen a response from anyone.

I've never heard of anyone blowing their motor under 450rwhp, so I'd consider that to be the bright-line border of safety. Exceed it without forged internals at your own risk.
