It’s not often that I see a full size kart on the dyno, but no surprise that Musgrave Racing leaves no stone un-turned.
Who makes full size kart dynos?
You can use an automotive dyno. Especially those like DynoDynamics and other eddy-current type dynos.
The dyno in the video looks to be this one:

I know Johnny West has one. Rodney Berryhill (Champion Racing). I’ve seen Josh Lane run his karts on one, but don’t recall who owned it.
