C6 Very high RPM, for pulling???

I've used C6s with good results in pulling but probably seldom seen much over 8500. We never shifted these out of 1st. And won't in the future if I were to use one. Now my question is whether anyone has ever used a C6 or does anyone think it would hold up in the range of 10,000 to 11,000 and with no shifting out of first. Any thoughts on whether it would withstand that kind of RPM?

Thanks, Bret

Here a couple of videos of one of my customers running a c6 turning 9500 rpm taking off in second gear.
