You'd rather use aerodynamic surfaces for turning as well as the speed increased.
It would start resembling aerobatic aircraft like Extra 300.
High aerodynamic acceleration is an old thing, it's how they actually discovered G-induced loss of consciousness. If you are mostly doing the racing with electronic motors, there's less noise and it's not as interesting anymore. Therefore some airstream operated whistle or siren would be useful, as you could deduce the speed directly from it:
But by this point, you are effectively left with a rocket that just happens to have some circular things that touch the ground.
