What's holding speed freaks back? Power or keeping the car down?

Both! LOL
The sound is cool too.

Air resistance, friction, etc.
The "breaking the laws of physics" is obviously a hyperbole though.

Getting to 200 will reveal alot of new little things that will eventually end up in the AE kits. Looks like they may need to add a wing to that rudder to prevent lift.

At 200mph the governing factor will be aerodynamics.
Overcoming the drag will require a huge amount of power from the motor (gearing up reduces the torque at the wheels so that wont help). The solution will be more volts and more powerful motors!
Downforce will be critical; too much and it will create even more drag (and dig itself into the floor). Too little and it will get airborne.
Awesome project, hope they hit the target!

I thought it looked familiar.

Both.... plus keeping the transmission together, keeping the tires on the wheels, keeping the bearings from melting, etc.
Don't know what technology they used here. But if I were trying it, I'd guess four 10,000KV brushless motors with axle bearings, one on each wheel, direct-drive; solid-rubber tires, and a single ESC that would make your eyes water. Plus a radio that had at least a mile range on the ground (aircraft radios have that range, but only because the model is up high).
Or, to cut to the chase... no electrics at all (except radio), freewheeling wheels... and a small turbine engine like they're using on model jets nowadays.
Those Associated guys are probably encountering problems we never imagined.
