What is the benefit of running NOS instead of a supercharger?

 

NOS is part time. Supercharging is full time. Both will put x-tra stress and heat on the engine. If you need more horse power all the time, go with the supercharger. If you want it only some times (like when you pull up next to a bowtie) pick the NOS system. Be prepared to spend much more on the supercharger and also expect a decrease in engine life.
