I can understand building the cryo tanks from carbon fibre for BFR means
developing new techniques and going beyond current state of the art. But
does Falcon 9 Heavy push any such limits or just scale existing tech
within what that tech is capable of?


Carbon fiber tanks will be something new for SpaceX, so it's a risk.
The question is, how big of a risk?


They've built a big tank and measured how much they can overpressure
it before it blows. They need to take another test article and
subject it to several hundred cryo cycles at something like 10%
overpressure and then tear it down to its component atoms and see how
it did.
