How to find the right Automotive Performance Nitrous Oxide Regulators AI guide

What the AI looks for in Automotive Performance Nitrous Oxide Regulators

Hold the pressure your jets assume
Nitrous jet charts commonly assume a bottle pressure of about 900 to 950 psi. Your air-fuel ratio is only as stable as the pressure feeding the jets. Pressure that drifts moves the tune lean or rich.
Fuel-side regulation
Set fuel pressure on the enrichment circuit to the value in your kit's jet chart, and regulate it independently if the kit calls for it. Wet kits are jetted against a specific fuel pressure. A regulator shared with the engine's fuel system can let the nitrous fuel supply sag.
Return vs deadhead
Match the regulator type to your fuel system's layout, either return-style or deadhead. The wrong type causes pressure creep or heat soak under nitrous load.
Fittings and media rating
Choose a regulator rated for the medium it will handle, nitrous or your fuel type including ethanol blends, with ports matching your AN lines. Seals not rated for the medium fail, and adapters add leak points.

Brands that matter

  • Aeromotive: Well-known fuel pressure regulators for performance fuel systems.
  • NOS: Nitrous-specific components, including pressure regulation parts.
  • Nitrous Express: Fuel system components designed around their kits.
  • Holley: Broad fuel regulator range, and the owner of NOS.

What to avoid

  • Running a wet kit off an unregulated fuel source
  • Regulators with no stated fuel compatibility when running ethanol blends
  • Setting fuel pressure by guesswork instead of with a gauge
