This is possible but the majority that you are referring to are in the experimental catagory.
NOS may be used in some race planes but have seen it only at the Reno Air Races and used only on a 15 minute race. The tanks needed for longer operation are far too large and heavy. By in large they make their power these days by running huge amounts of boost (120 inches) with very special fuels on the old WW2 transport engines.
The FAA mandates that any engine that is used in a certified airplane has to comply with a "Type certificate data sheet" and the limits on this are very strict. Lower compressions and turning low speed (prop limits) as well as magnetos for ignition in 99% of the cases so we are back to tractor era equipment.
