For you tech hungry junkies? we will provide some details explaining what makes this nitrous system so great. The key to maximizing nitrous horsepower is to keep the nitrous in a dense liquid form until it is injected into the engine. Sharp bends in the nitrous flow path cause the nitrous flow to become turbulent which causes gaseous bubbles to form in the flowing nitrous. Dense liquid nitrous makes more power than gaseous nitrous ? Period! This NX nitrous system contains the key components that ensure you are getting maximum power per pound of nitrous used.
