Product Details

The Nitrous Express 55040-15 is a conventional RNC (Restricted Nitrous Class) nitrous oxide injection system designed for the 4150 carburetor flange and built specifically for gasoline applications. This kit is the first choice among professional racers competing in classes where jet size is restricted, as it is engineered to extract maximum power from any given jet size.

At the core of this system is a CNC billet nitrous plate with enlarged nitrous passages and a .178" orifice Lightning nitrous solenoid. Combined with an 8AN feed line and a .500" orifice Lightning 500 bottle valve, these components work together to deliver an exceptionally dense liquid nitrous charge — allowing the maximum possible nitrous flow through a restricted jet. The result is more horsepower per jet size than any competing system on the market.

Kit Features:

  • CNC billet nitrous plate with enlarged nitrous passages for optimized flow
  • .178" orifice Lightning nitrous solenoid
  • .500" orifice Lightning 500 bottle valve
  • 8AN nitrous feed line
  • Lightning series fuel solenoid
  • Stainless hard lines connecting solenoids to plate
  • Heavy-duty relay, switches, and stainless bottle brackets
  • 15lb nitrous bottle included
  • Every nut, bolt, and electrical connector needed for installation

Nitrous Express backs this system with a satisfaction guarantee — if you don't make the most horsepower per jet size, NX will provide a full refund. The 55040-15 ships as a complete, ready-to-install kit for 4-barrel 4150 carburetor applications running gasoline.
