This system includes 8 of the patented NX Shark Nozzles, 2 NX Lightning 250 Nitrous solenoids, 2 NX Lightning series fuel solenoids, anodized aluminum distribution blocks, 3/16 stainless hard lines, nickel plated fittings, Jetting for 200-2100HP, D-8 stainless braided nitrous feed lines, a high flow D-8 Y fitting, a wide open throttle switch, 40 Amp relays and relay harnesses, master arming switch, stainless bottle brackets and a 15 lb nitrous bottle with the DF5 bottle valve. This system includes the latest technology and the best components available. 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. Read on and we’ll explain. NX Lightning solenoids feature an improved flow path that allows nitrous / fuel to enter above the seat and exit out the bottom for flow unmatched by any other solenoid on the market. Lightning Series solenoids feature CNC aluminum bodies for the ultimate in weight savings. Nitrous Express only uses the highest quality, made in the USA components in its solenoids. Do not be fooled by low price come-ons, the solenoids are the most important component of a nitrous system. The billet aluminum DF5 bottle valve not only looks great; It is packed with features including an integrated gauge port, an integrated push port, a large .500 orifice and a straight through flow path. The DF5 valve includes a locking handle to prevent accidental opening.
