thrashing to the red line gets you worried? geeze, my RB25 spends 99% of its time on the limiter Ive thrashed my RB's more then most people on here will ever do... and not had one blow, let alone a power run on the dyno
as joel said, its a good opportunity to run it up anc check your AFR's and make sure all is A OK as you never know when your fuel pump might decide to cark it
