Cars using NOS (nitrous oxide) can easily hit 175 or 200 mph. Such speed creates unimaginable stress, making engine reinforcement a necessity that can cost up to $3,000. The NOS kits â bottles, lines, intake interface, electronics, clips and all â cost from about $350 to $650. NOS works two ways: a.
