Nitrous Express Hellcat Supercharger Lid Nitrous & Water Injection Kit (100–400 HP) — No Bottle
Designed for supercharged 6.2L HEMI platforms, this Nitrous Express system replaces the factory lid with a CNC-machined billet supercharger lid featuring integrated, spraybar-less nitrous/fuel passages and provisions for water/meth assist. The result is clean plumbing, even mixture distribution, cooler charge temps, and reliable gains from 100–400 HP when properly jetted and tuned. This version ships without a nitrous bottle, so you can pair it with the bottle size, valve, and accessories of your choice.
Key Features
- Billet Aluminum Lid: Precision CNC-machined replacement improves airflow and integrates internal nitrous/fuel routing for a tidy install.
- Spraybar-less Distribution: Internal passages promote even N2O/fuel delivery across the supercharger discharge.
- 100–400 HP Capability: Supports multiple jet options with appropriate tuning, fueling, and ignition changes.
- Water/Meth Compatibility: Supports charge-cooling strategies for knock resistance and repeatable performance.
- Direct-Fit: Uses OEM-style mounting points for Hellcat-family applications.
Product Notes
- Included: Billet supercharger lid, integrated passages, solenoids/lines/hardware as specified for the lid system.
- Not Included: Nitrous bottle, bottle brackets, heater, pressure gauge/monitoring devices (select to suit your build).
- Tuning & Plugs: Calibration, wideband monitoring, and colder spark plugs recommended for the selected shot.
- Emissions: Not CARB approved, for off-road/competition use where permitted.
- Prop 65: May expose you to chemicals known to the State of California to cause cancer or reproductive harm.
- Availability: May be special-order, lead times can apply.
Installation Notes
- Professional installation recommended. Inspect/clean sealing surfaces, torque fasteners to OEM specification.
- Route nitrous/fuel (and water-meth if used) per NX guidelines, verify bottle pressure control and safety devices (WOT/window switch).
- Confirm AFR and ignition timing for the selected shot, use appropriate octane and fuel system capacity.

Forced Induction
Forced induction systems encompass every method of pushing air into an engine at greater than atmospheric pressure, including turbochargers driven by exhaust energy, superchargers driven mechanically by the crankshaft, and prochargers using centrifugal designs belt-driven at higher ratios than traditional roots-type blowers, with each approach delivering a significant increase in air mass per cylinder fill that allows proportionally more fuel to be burned and more power to be produced without increasing engine displacement. Adding 10 PSI of boost pressure to a naturally aspirated engine can increase power output by 50 to 70 percent depending on the engine's breathing efficiency and the quality of the supporting hardware, making forced induction the most power-dense modification available relative to cost and complexity. This collection covers complete forced induction systems, turbocharger and supercharger hardware, intercoolers, blow-off valves, wastegates, and supporting component...
