I’m not much into dyno numbers.

Awesome video! Neat thing about hub dynos, since the dyno is connected in-line with the drive axles there is no risk of the vehicle "falling off" the dyno (driving off the rollers) and it doesn't need to be strapped down. That's why you are able to see the car lift up just like it would if it was launching at the strip. A neat benefit of that is you can watch the chassis and suspension and see how it handles the power, to some extent... still no reaction forces being applied forward but you can see the reaction torque on the driveline and chassis doing its thing.
